[0023] One or more specific embodiments of the present disclosure will be described below. These described embodiments are examples of the presently disclosed techniques. Additionally, in an effort to provide a concise description of these embodiments, all features of an actual implementation may not be described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

[0024] When introducing elements of various embodiments of the present disclosure, the articles “a,”“an,” and “the” are intended to mean that there are one or more of the elements. The terms “comprising,”“including,” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements. Additionally, it should be understood that references to “one embodiment” or “an embodiment” of the present disclosure are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features.

[0025] As used herein, the terms “approximately,”“generally,” and “substantially,” and so forth, are intended to convey that the property value being described may be within a relatively small range of the property value, as those of ordinary skill would understand. For example, when a property value is described as being “approximately” equal to (or, for example, “substantially similar” to) a given value, this is intended to mean that the property value may be within + / −5%, within + / −4%, within + / −3%, within + / −2%, within + / −1%, or even closer, of the given value. Similarly, when a given feature is described as being “substantially parallel” to another feature, “generally perpendicular” to another feature, and so forth, this is intended to mean that the given feature is within + / −5%, within + / −4%, within + / −3%, within + / −2%, within + / −1%, or even closer, to having the described nature, such as being parallel to another feature, being perpendicular to another feature, and so forth. Further, it should be understood that mathematical terms, such as “planar,”“slope,”“perpendicular,”“parallel,” and so forth are intended to encompass features of surfaces or elements as understood to one of ordinary skill in the relevant art, and should not be rigidly interpreted as might be understood in the mathematical arts. For example, a “planar” surface is intended to encompass a surface that is machined, molded, or otherwise formed to be substantially flat or smooth (within related tolerances) using techniques and tools available to one of ordinary skill in the art. Similarly, a surface having a “slope” is intended to encompass a surface that is machined, molded, or otherwise formed to be oriented at an angle (e.g., incline) with respect to a point of reference using techniques and tools available to one of ordinary skill in the art.

[0026] As briefly discussed above, the present disclosure is directed to an exercise activity monitoring system configured to be incorporated with eyewear worn by a user during a physical or other activity (e.g., exercise activity). For example, the exercise activity monitoring system may be utilized with swim goggles, sunglasses, ski goggles, helmet visors, other protective eyewear, and / or any other suitable eyewear that may be worn by the user. The exercise activity monitoring system may be utilized during a physical activity (e.g., exercise), such as swimming, running, cycling, skiing, hiking, walking, motor sporting, and so forth. The exercise activity monitoring system includes components configured to enable monitoring, tracking, storage, and transmission of metrics associated with the physical activity carried out by the user. For example, the exercise activity monitoring system may include one or more sensors configured to measure or detect an activity parameter related to the user and / or the physical activity, and the exercise activity monitoring system may include a memory and / or storage device configured to track and store values of the activity parameter (e.g., data) during performance of the physical activity.

[0027] In accordance with present techniques, the exercise activity monitoring system includes an unobtrusive (e.g., minimally intrusive) and / or small form factor that enables securement of the exercise activity monitoring system to the eyewear in a manner that enables reduced obstruction of the user's field of vision during the physical activity. For example, the exercise activity monitoring system may be secured to the eyewear in a location that is adjacent or external to a peripheral field of vision of the user. In other words, the exercise activity monitoring system may be secured to the eyewear such that the exercise activity monitoring system is not within the user's central field of vision and / or line of sight (e.g., forward line of sight). In this way, the exercise activity monitoring system may not distract or otherwise interrupt the user during the physical activity.

[0028] Additionally, present embodiments of the exercise activity monitoring system include a modular design or configuration that enables convenient installation, removal, and reinstallation of the exercise activity monitoring system with one or more embodiments of the eyewear. The exercise activity monitoring system is also configured to be secured (e.g., attached, mounted, fixed) to the eyewear in a fixed position. Specifically, the exercise activity monitoring system may be secured to the eyewear such that the exercise activity monitoring system does not move, shift, or otherwise change position relative to the eyewear and relative to the user during the physical activity. For example, the eyewear may be secured to a head of the user in a fixed position, and the exercise activity monitoring system secured to the eyewear may therefore be fixed in position relative to the head of the wearer. In this way, the exercise activity monitoring system enables improved (e.g., more reliable, more consistent) detection and tracking of metrics (e.g., physiological parameters) of the user during the physical activity. While the embodiments discussed below are described in the context of the exercise activity monitoring system incorporated with swim goggles, it should be appreciated that other embodiments incorporating the present techniques may be utilized with other eyewear.

[0029] Turning now to the drawings, FIG. 1 illustrates an embodiment of an activity system 10, illustrating an exercise activity monitoring system 12 (e.g., sensing system, sensor system, monitoring system, exercise monitoring system, swimming data detection system) that may be implemented with one or more types of eyewear 14 that may be utilized by a user during various activities (e.g., physical activities). For example, the exercise activity monitoring system 12 may be implemented with swim goggles 16, sunglasses 18, ski goggles 20, a helmet visor 22, protective glasses, prescription sports glasses, shooting glasses, automobile driving glasses, and / or other suitable types of eyewear 14 that may be worn by a user during physical activity, such as exercise or athletic competition (e.g., a racing event). The exercise activity monitoring system 12 may be configured as a module configured to be removably secured to the eyewear 14. For example, the exercise activity monitoring system 12 may be secured to and removed from an embodiment of the eyewear 14 (e.g., swim goggles 16) without the use of tools or other specialized instruments.

[0030] The exercise activity monitoring system 12 is configured to detect one or more parameters related to an activity performed by a user wearing the eyewear 14 having the exercise activity monitoring system 12 attached thereto. For example, as discussed further below, the exercise activity monitoring system 12 may include one or more internal sensors (e.g., disposed within the exercise activity monitoring system 12) configured to detect an activity parameter (e.g., data) related to the activity being performed by the user. The sensors of the exercise activity monitoring system 12 may be configured to detect biometric parameters of the user, physiological parameters of the user, environmental parameters, activity parameters, performance parameters, and / or any other suitable parameter related to the activity performed by the user. In some implementations, the activity may include swimming 24, bicycling 26, running 28, motorcycling 30 (e.g., motorsports), skiing 32, and / or any other suitable activity (e.g., physical activity, exercise). Further, in some embodiments, the exercise activity monitoring system 12 may interface with (e.g., receive data from) one or more external sensors 34 that may be worn by the user and / or disposed in certain equipment and may be configured to detect other parameters associated with the activity being performed.

[0031] The exercise activity monitoring system 12 is also configured to store data, such as measured values of the one or more activity parameters detected by the exercise activity monitoring system 12. After completion of the activity (e.g., exercise, athletic competition) the data may be transferred and / or transmitted to an external device 36, such as a mobile device, a tablet, a laptop computer, an electronic notebook, external computing system, and / or other external system. In some embodiments, the exercise activity monitoring system 12 may transmit data stored thereon to a cloud-based system 38. The external device 36 and / or the cloud-based system 38 may be utilized to view, analyze, and / or process the data received from the exercise activity monitoring system 12. For example, the external device 36 may be a mobile device configured to execute software (e.g., an application) that receives, displays, analyzes, and / or processes the data. In some embodiments, the external device 36 may execute software to process the data and derive one or more activity metrics (e.g., performance metrics) indicative of the user's execution of the activity. The metrics may then be displayed (e.g., via the external device 36) for review by the user. In this way, the user may assess and evaluate the user's performance of the activity.

[0032] As discussed in further detail below, the exercise activity monitoring system 12 is configured to be removably secured to the eyewear 14 (e.g., swim goggles 16), such that the exercise activity monitoring system 12 may remain fixed relative to the eyewear 14 and relative to the user during the activity performed by the user wearing the eyewear 14. As a result, the exercise activity monitoring system 12 may more accurately detect and / or measure one or more activity parameters of the user during the activity. Further, the exercise activity monitoring system 12 includes a small form factor, such that the exercise activity monitoring system 12 may be secured to the eyewear 14 in a position that does not obstruct the user's central field of vision, thereby enabling detection, monitoring, and tracking of the activity parameters (e.g., via sensors of the exercise activity monitoring system 12) during the activity with substantially reduced distraction of the user.

[0033] FIG. 2 is a front perspective view of an embodiment of the swim goggles 16 including an embodiment of the exercise activity monitoring system 12, and FIG. 3 is a rear perspective view of the swim goggles 16 including the exercise activity monitoring system 12, in accordance with the present techniques. FIGS. 2 and 3 will be discussed concurrently below. The swim goggles 16 and the exercise activity monitoring system 12 may be cooperatively considered or described as a swim race data capture system, in some embodiments. In the illustrated embodiments, the swim goggles 16 include a left lens 40 (e.g., eyepiece, goggle lens, eye goggle) and a right lens 42 (e.g., eyepiece, goggle lens, eye goggle) coupled together via a nose bridge 44. The left lens 40 and right lens 42 each include a respective lens seal 46 (e.g., eye seal, gasket, face pad, cushion) extending about a respective rim or edge of each lens 40, 42. The swim goggles 16 also include a strap coupled to the left lens 40 and right lens 42 to enable positioning of the swim goggles 16 on a face of the user.

[0034] As shown, the exercise activity monitoring system 12 is disposed within an inner cavity 48 defined by the left lens 40. More specifically, the exercise activity monitoring system 12 is disposed within the inner cavity 48 adjacent (e.g., abutting) an outer edge 50 (e.g., outer lateral edge, lateral edge) of the left lens 40. Due to the relatively small form factor of the exercise activity monitoring system 12, the exercise activity monitoring system 12 within the left lens 40 occludes a relatively small portion of a front face 52 of the left lens 40. Indeed, the exercise activity monitoring system 12 disposed at the outer edge 50 of the left lens 40 may occlude a portion of a peripheral field of view of the user, but the exercise activity monitoring system 12 may not occlude a central field of view 54 (e.g., forward field of view) of the user wearing the swim goggles 16 with the exercise activity monitoring system 12 secured within the inner cavity 48. Thus, during a swimming 24 exercise or race event, the user wearing the swim goggles 16 with the exercise activity monitoring system 12 may not be distracted by the presence of the exercise activity monitoring system 12 within the left lens 40 and may instead remain focused on performing the swimming 24 exercise or race event.

[0035] As mentioned above, the exercise activity monitoring system 12 may be configured to enable simplified installation and removal of the exercise activity monitoring system 12. For example, the exercise activity monitoring system 12 may be removed from the left lens 40 and may be installed within the right lens 42, such as within an inner cavity 56 of the right lens 42 and at an outer edge 58 of the right lens 42. Additionally or alternatively, the exercise activity monitoring system 12 may be removed from the left lens 40 and installed within another pair of swim goggles 16. In accordance with present techniques, the exercise activity monitoring system 12 is configured to be secured (e.g., positionally secured) within the swim goggles 16 (e.g., within the inner cavity 48 of the left lens 40) such that the exercise activity monitoring system 12 does not move or shift during use of the swim goggles 16 (e.g., swimming 24). In other words, in an installed configuration, the exercise activity monitoring system 12 is configured to be fixed in position relative to the swim goggles 16 (e.g., left lens 40) and therefore fixed in position relative to a head of the user wearing the swim goggles 16 (e.g., in an operational configuration of the swim goggles 16). Securement of the exercise activity monitoring system 12 within the swim goggles 16 is described in further detail below.

[0036] FIG. 4 is block diagram of an embodiment of an exercise activity monitoring system 12, illustrating various components 80 that may be included within the exercise activity monitoring system 12. The exercise activity monitoring system 12 may include a housing 82 (e.g., modular housing, compartment, enclosure, module) configured to contain the components 80. In some embodiments, the housing 82 is a waterproof or watertight housing configured to block (e.g., prevent) entry of water into the housing 82. As discussed further below, the housing 82 may have a shape, geometry, and / or configuration that enables installation of the exercise activity monitoring system 12 within the swim goggles 16 (e.g., left lens 40, right lens 42) or other eyewear 14 in a manner that reduces (e.g., minimizes) visual obstruction of a user wearing the swim goggles 16. The shape, geometry, and / or configuration of the housing 82 may also enable reliable securement of the exercise activity monitoring system 12 within the swim goggles 16, such that the exercise activity monitoring system 12 does not move or shift (e.g., relative to the swim goggles 14, relative to the user) during an activity of the user (e.g., swimming 24). In this way, the present techniques may enable more reliable detection and tracking of activity parameters via the exercise activity monitoring system 12.

[0037] As mentioned above, the components 80 of the exercise activity monitoring system 12 may include one or more sensors 84 (e.g., internal sensors). The sensors 84 may include heart monitoring sensors, such as photoplethysmographic (PPG) sensors, plethysmographic sensors, piezoelectric sensors, pulse oximetry sensors (e.g., light sensors), accelerometers, gyroscopic sensors, biometric sensors, temperature sensors, magnetometers, electrocardiogram sensors, health informatics sensors (e.g., ISO / IEEE 11073 sensors), a global positioning system (GPS), and / or any other suitable type of sensor 84. The sensors 84 may detect any suitable activity parameter, such as activity parameters related to swimming 24 activities and performance of the user engaged in the swimming 24 activity.

[0038] The components 80 of the exercise activity monitoring system 12 may also include processing circuitry 86 and a memory 88 (e.g., storage device, memory device). In some embodiments, the processing circuitry 86 includes a microprocessor, which may execute software for controlling one or more of the components 80 of the exercise activity monitoring system 12. The processing circuitry 86 may include multiple microprocessors, one or more “general-purpose” microprocessors, one or more special-purpose microprocessors, one or more field programmable arrays (FPGAs), one or more reduced instruction set (RISC) processors, one or more application specific integrated circuits (ASICS), or some combination thereof. The memory 88 may be configured to store information, such as instructions, control software, data tables, configuration data, data collected by the sensors 84, and so forth. The memory 88 may include a volatile memory, such as random access memory (RAM), and / or a nonvolatile memory, such as read-only memory (ROM). The memory 88 may store a variety of information and may be used for various purposes. For example, the memory 88 may store processor-executable instructions including firmware or software for the processing circuitry 86 to execute, such as instructions for controlling one or more components 80 of the exercise activity monitoring system 12. In some embodiments, the memory 88 is a tangible, non-transitory, machine-readable-medium that may store machine-readable instructions for the processing circuitry 86 to execute. For example, the processing circuitry 86 may execute instructions (e.g., code) stored on the memory 88 to process (e.g., analyze) data from the sensors 84 that is stored on the memory 88, such as to derive one or more activity metrics based on the data. The memory 88 may include ROM, flash memory, a hard drive, or any other suitable optical, magnetic, or solid-state storage medium, or a combination thereof. The components 80 also include a power supply 90 (e.g., battery) disposed within the housing 82 and configured to provide power to one or more of the components 80. The power supply 90 may include one or more rechargeable batteries that are chargeable via induction charging techniques and / or wired charging techniques.

[0039] In the illustrated embodiment, the exercise activity monitoring system 12 also includes communication circuitry 92. The communication circuitry 92 is configured to enable communication between the exercise activity monitoring system 12 and an external system, such as the external device 36 and / or the cloud-based system 38. The communication circuitry 92 may be configured to enable wired and / or wireless communications. For example, the communication circuitry may include circuitry communications via Wi-Fi (e.g., IEEE 802.11X), cellular (e.g., HSPA, HSPA+, long term evolution LTE, WiMax), near field communications (NFC), Bluetooth, including low power Bluetooth, personal area networks (PANs), Zigbee, Z-wave, wireless mesh networks, and so forth. As previously mentioned, the communication circuitry 92 may be configured to transmit data (e.g., sensor 84 data) stored in the memory 88 to an external system, such as the external device 36.

[0040] The components 80 of the exercise activity monitoring system 12 may also include one or more input / output (I / O) devices 94, in some embodiments. The one or more I / O devices 94 may enable a user to adjust operation of the exercise activity monitoring system 12. For example, the I / O devices 94 may include one or more buttons, switches, sensors (e.g., touch sensors), and so forth configured to receive an input (e.g., a gesture input, such as swiping, tapping, pressing, holding) from the user. The user may utilize one or more of the I / O devices 94 to power the exercise activity monitoring system 12 on and / or off, change an operating mode of the exercise activity monitoring system 12, and so forth. In some embodiments, the I / O devices 94 may include an output device, such as a light emitting diode (LED), which may provide feedback indicative of an operating state (e.g., on, off) and / or operating mode of the exercise activity monitoring system 12.

[0041] The exercise activity monitoring system 12 also includes an inertial measurement unit (IMU) 96. The IMU 96 (e.g., six-axis IMU, nine-axis IMU) may include one or more sensors, such as a specific force sensor, an angular rate sensor, an accelerometer 98, a gyroscope 100, and / or magnetic field change sensors (e.g., magnetometers) that may detect and / or measure inertial measurements during use of the exercise activity monitoring system 12 (e.g., based on movement of the exercise activity monitoring system 12). The IMU 96 may be configured to detect one or more degrees of freedom (DOF) measurements indicative of a user's performance of an activity (e.g., swimming 24), as described in more detail below. The IMU 96 (e.g., accelerometer 98, gyroscope 100) may be communicatively coupled to the memory 88, and the memory 88 may be configured to store data detected and / or captured by the IMU 96.

[0042] In some embodiments, the exercise activity monitoring system 12 may include other components 80, such as a timer 102 (e.g., clock) that may track one or more elapsed time periods during an activity of a user wearing eyewear 14 (e.g., swim goggles 16) with the exercise activity monitoring system 12. Time periods tracked by the timer 102 may be stored in the memory 88 and may be transmitted (e.g., to one of the external devices 36) via the communication circuitry 92 for review and assessment by the user after completion of the activity (e.g., swimming 24). Further, in some embodiments, the exercise activity monitoring system 12 may include one or more circuit boards 104 (e.g., printed circuit board), which may enable communicative coupling between one or more of the components 80. For example, one or more of the components 80 may be disposed on (e.g., soldered to) the circuit board 104, and the circuit board 104 may be configured to transmit data, signals, and / or other information between components 80 of the exercise activity monitoring system 12. As mentioned above, one or more of the components 80 (e.g., memory 88, IMU 96, accelerometer 98, gyroscope 100, sensors 84, circuit board 104, timer 102, etc.) may be electrically coupled to and configured to receive power from the power supply 90 (e.g., battery) to enable operation of the one or more components 80.

[0043] In accordance with present techniques, the exercise activity monitoring system 12 may also include one or more retainers 106 (e.g., securement, attachment feature, fastener, adhesive, etc.). As discussed in further detail below, the one or more retainers 106 may be features (e.g., physical features) configured to enable securement of the exercise activity monitoring system 12 to the eyewear 14 (e.g., swim goggles 16). For example, the one or more retainers 106 may include a tab, a clip, a retaining ring, a retention segment, a biasing member (e.g., spring, gasket), and / or any other suitable positioning, biasing, and / or securement feature configured to fix and / or retain a position of the exercise activity monitoring system 12 (e.g., relative to the left lens 40, relative to the right lens 42) in an installed configuration of the exercise activity monitoring system 12 with the eyewear 14 (e.g., swim goggle 16). In some embodiments, one or more of the retainers 106 may be integrated with the housing 82 and / or may be physical features of the housing 82. Additionally or alternatively, one or more of the retainers 106 may be a component separate from the housing 82 and may be configured to engage with the housing 82 to retain the housing 82 in a desired position in an installed configuration of the exercise activity monitoring system 12 with the eyewear 14 (e.g., with the swim goggles 16). In some embodiments, the housing 82 and / or one or more of the retainers 106 may have a geometry and / or contour configured to match with (e.g., correspond to) a corresponding contour, shape, or geometry of a portion of the swim goggles 16 (e.g., left lens 40, right lens 42, outer edge 50, outer edge 58).

[0044] It should be noted that the exercise activity monitoring system 12 does not include a display, such as an LED display, a micro LED display, a display screen, a display projector, a direct display system, an indirect display system, or other display system. That is, the exercise activity monitoring system 12 does not include a display configured to output or project light (e.g., an image, an alphanumeric character, a symbol, etc.) to a user to provide feedback or other information to the user during use of the exercise activity monitoring system 12 (e.g., during an activity, during swimming 24). Thus, the exercise activity monitoring system 12 is configured to detect and track activity parameters of the user with substantially reduced (e.g., minimal) distraction to the user during the activity. Further, the omission of any display system (e.g., real-time display system, activity feedback display system) in the exercise activity monitoring system 12 may also enable the exercise activity monitoring system 12 to satisfy one or more regulatory standards or qualifications, such as standards mandated by a governing entity or body for a certain activity, sport, event, and / or discipline (e.g., athletic competitions, sanctioned athletic competitions). In other words, the exercise activity monitoring system 12 according to the present techniques may qualify for use in certain regulated or administered activities or events, such as competitions, races, and so forth. The omission of a display system in the exercise activity monitoring system 12 may also reduce power usage by the exercise activity monitoring system 12 and enable a reduction in size of the exercise activity monitoring system 12, which may further contribute to reduced (e.g., minimized) obstruction of a field of view of a user of the exercise activity monitoring system 12.

[0045] FIG. 5 is a schematic flow diagram of an embodiment of a process 120 for utilizing the exercise activity monitoring system 12 with eyewear 14. The process 120 and / or certain steps of the process 120 may be implemented as computer-executable instructions (e.g., stored on the memory 88) executed via the processing circuitry 86, the external device 36 (e.g., mobile phone), the cloud-based system 38, another external computing system, or any combination thereof. It should be understood that the process 120 may include steps that are optional, and that the steps may be performed in other order than that shown in FIG. 5. Indeed, it should be appreciated that any of the functions, and / or operations described herein may be incorporated as one or more steps of the process 120.

[0046] In the illustrated embodiment, the exercise activity monitoring system 12 is incorporated with swim goggles 16 worn by a user 122 engaged in swimming 24 activity. As the user 122 swims, the exercise activity monitoring system 12 may collect data indicative of the performance and / or actions of the user 122 during the swimming 24 activity. In accordance with the present techniques, the exercise activity monitoring system 12 may be utilized to perform one or more steps of the process 120 during swimming 24 as a leisurely activity, as a training activity, as an athletic competition (e.g., a swimming race), and so forth. To this end, as indicated by block 124 of the process 120, the exercise activity monitoring system 12 (e.g., processing circuitry 86) may receive data, such as data indicative an activity parameter detected by one or more of the sensors 84 and / or the IMU 96 (e.g., IMU system). Data from the timer 102 may also be received, in some embodiments. As mentioned above, the IMU 96 may include one or more sensors (e.g., specific force sensor, angular rate sensor, accelerometer, gyroscope, magnetic field change sensor, magnetometer) that may be configured to detect multiple degrees of freedom of a head 126 of the user 122. For example, the IMU 96 may be configured to detect a position of the head 126 of the user 122 and / or changes in a position of the head 126 of the user 122 during the swimming 24 activity. In the illustrated embodiment, six degrees of freedom are provided by the IMU 96, including pitch 128, roll 130, yaw 132, movement and / or position along a vertical axis 134 (e.g., upward direction 136, downward direction 138), movement and / or position along a lateral axis 140 (e.g., left direction 142, right direction 144), and movement and / or position along a directional axis 146 (e.g., direction of travel axis, forward direction 148, and backward direction 150).

[0047] As discussed above, present embodiments include the exercise activity monitoring system 12 configured to be positionally fixed (e.g., attached, secured) to the eyewear 14 (e.g., swim goggles 16), such that the exercise activity monitoring system 12 does not move or shift relative to the eyewear 14 and / or relative to the head 126 of the user 122 during use of the exercise activity monitoring system 12 and performance of an activity (e.g., physical activity, swimming 24). Thus, in the illustrated embodiment, the sensors 84 and / or the IMU 96 may remain fixed relative to the swim goggles 16 and the head 126 of the user 122, which enables detection and collection of more accurate, more precise, and more reliable data via the sensors 84 and / or the IMU 96. For example, the present techniques enable detection of data indicative of a position of the head 126 of the user 122, including changes in the position of the head 126, throughout the swimming 24 activity in a more accurate manner. As a result, the data captured by the exercise activity monitoring system 12 may enable the user 122 to more thoroughly and precisely assess and evaluate the performance (e.g., action, behavior, response, consistency) of the user 122 after the swimming 24 activity, which enables the user 122 to improve future performance in swimming 24.

[0048] The data received from the sensors 84 and / or IMU 96 may be stored by the exercise activity monitoring system 12, as indicated by block 152. For example, the data may be stored in the memory 88. Indeed, the sensors 84 and / or the IMU 96 may continuously and / or continually measure and / or collect data indicative of one or more activity parameters (e.g., performance parameters, physical parameters) of the user 122 performing the swimming 24 activity, and the exercise activity monitoring system 12 may continuously and / or continually store the data in the memory 88. The process 120 may also include deriving one or more activity metrics, as indicated by block 154, via the data collected by the sensors 84 and / or the IMU 96. For example, in some embodiments, the processing circuitry 86 of the exercise activity monitoring system 12 may be configured to analyze, manipulate, and / or otherwise process the data (e.g., captured by the sensors 84 and / or IMU 96) to derive one or more activity and / or performance metrics. In other embodiments, one or more activity and / or performance metrics may be derived from the data by the external device 36 (e.g., mobile phone). As mentioned above, the activity and / or performance metrics derived may include a position of the head 126 of the user 122 during and / or throughout the swimming 24 activity.

[0049] It should be appreciated that the data received from the sensors 84 and / or IMU 96 may be indicative of any suitable activity and / or performance parameter related to the activity performed by the user 122. Similarly, the activity and / or performance metrics derived via the data may include any suitable activity metric related to the activity performed by the user 122. In an implementation with swimming 24, the activity parameters and / or activity metrics may include head 126 position, a stroke pattern (e.g., stroke frequency, stroke consistency, stroke type), a kicking cadence, a flip turn parameter (e.g., time, rotational speed, pushing force), race times and / or splits (e.g., underwater time, total time, lap time), a breathing pattern (e.g., breathing frequency, breath duration, breath speed), a start parameter (e.g., reaction time, leaping force), a direction of travel (e.g., in open water swimming), length of travel, speed of travel, another suitable activity parameter and / or activity metric, or any combination thereof. It should be appreciated that data indicative of any suitable activity and / or performance parameters may be detected and any suitable activity and / or performance metrics may be derived that is related to a particular activity of the user 122 utilizing the exercise activity monitoring system 12.

[0050] The process 120 further includes transferring the data, as indicated by block 156. As discussed above, the exercise activity monitoring system 12 may transfer the data to an external system, such as the external device 36. In some embodiments, the exercise activity monitoring system 12 may be configured to transfer the data (e.g., via communication circuitry 92) after completion of the activity performed by the user 122. In other embodiments, the exercise activity monitoring system 12 may be configured to transfer the data (e.g., via communication circuitry 92) as the user 122 performs the activity, such as for viewing and / or assessment by another person (e.g., a trainer, a coach, an athletic competition official, an observer of the activity). In some embodiments, the data may be transferred, during performance of the activity, to an external system for evaluation of compliance with one or more rules, regulations, and / or other metrics associated with performance of the activity. For example, the exercise activity monitoring system 12 may be utilized to capture data indicative of the position of the head 126 of the user 122, and the data may be transferred to an external system for derivation of a metric indicative of a performance, behavior, decision, or other action of the user 122, which may be assessed for evaluation by an official (e.g., competition official, referee, judge, etc.) associated with the activity.

[0051] In any case, the exercise activity monitoring system 12 does not include a display system configured to display or output visual feedback (e.g., light, data, derived activity metric, image, symbol, alphanumeric character) to the user 122 during the activity, which enables the user 122 to more completely focus on performing the activity. The data transferred to the external system (e.g., external device 36) may then be viewed, analyzed, processed (e.g., to derive an activity metric), and / or otherwise manipulated or referenced via the external system to evaluate the performance of the user 122 during the activity, but the user 122 utilizing the exercise activity monitoring system 12 may not be able to view or perceive an output (e.g., data, light, display) of the exercise activity monitoring system 12 during performance of the activity 12. Accordingly, the user 122 may utilize the exercise activity monitoring system 12 to capture data indicative of a quality or performance of the activity during certain events of the activity (e.g., athletic competitions) that do not permit use of particular types of feedback devices (e.g., visual feedback devices).

[0052] FIG. 6 is a rear perspective view of an embodiment of a portion of the swim goggles 16 including an embodiment of the exercise activity monitoring system 12 disposed within the inner cavity 48 defined by the left lens 40. The left lens 40 also includes the lens seal 46. In the illustrated embodiment, the lens seal 46 includes one or more of the external sensors 34, which may be communicatively coupled to the exercise activity monitoring system 12, such as via a wired or wireless connection.

[0053] The lens seal 46 may include a seal body 180 formed from any suitable material, such as silicone, foam, or other suitable material. The lens seal 46 is disposed about an edge of an eyepiece 182 (e.g., eye goggle) of the left lens 40. The eyepiece 182 may be formed from any suitable translucent or transparent material, such as plastic. One or more of the external sensors 34 may be at least partially embedded within the seal body 180. Additionally or alternatively, one or more of the external sensors 34 may be disposed on an outer surface 184 of the seal body 180. When the swim goggles 16 are worn by a user (e.g., user 122), the seal body 180 may be positioned against the face (e.g., skin) of the user, and the outer surface 184 of the seal body 180 may disposed about an eye (e.g., left eye) of the user 122. In other words, the seal body 180 and / or the eyepiece 182 may circumscribe an eye (e.g., a single eye) of the user 122, such that the inner cavity 48 of the left lens 40 is exposed to the eye of the user 122. The seal body 180 may be biased (e.g., pressed) against the face of the user 122, which may create a watertight seal between the left lens 40 and the face of the user 122 to block water from entering the inner cavity 48 of the left lens 40 during swimming 24. The positioning of the seal body 180 against the face of the user 122 may also enable the external sensors 34 to detect data indicative of one or more activity parameters (e.g., physiological parameters, performance parameters) of the user 122 during the activity (e.g., swimming 24).

[0054] In some embodiments, the external sensors 34 may include a PPG sensor, a piezoelectric sensor, a resistance-based sensor, a temperature sensor, an electrocardiogram sensor, a health informatics sensor (e.g., ISO / IEEE 11073 sensor), and / or any other suitable type of sensor. One or more of the external sensors 34 may be positioned within and / or against the seal body 180 to enable the external sensor 34 to a supraorbital artery region, an angular artery region, a temporal artery region, and / or other region of the face of the user 122 to enable detection and / or capture of data indicative of an activity parameter (e.g., physiological parameter) of the user 122 during swimming 24, such as heart rate, a volumetric measurement (e.g., plethysmogram), temperature, and / or another suitable activity parameter.

[0055] FIG. 7 is a rear perspective view of another embodiment of a portion of the swim goggles 16 including an embodiment of the exercise activity monitoring system 12 disposed within the inner cavity 48 defined by the left lens 40. The illustrated embodiment also includes the lens seal 46 having the seal body 180 with multiple external sensors 34 (e.g., sensors external to the housing 82) embedded within the seal body 180. Any suitable number of external sensors 34 may be embedded within the seal body 180, and the external sensors 34 may be arranged in any desired position within the seal body 180. As similarly discussed above, the external sensors 34 may be piezoelectric sensors configured to detect data indicative of cardiac rhythm and / or heart rate. For example, the external sensors 34 may include one or more multi-angled piezoelectric sensors. Data collected by the external sensors 34 may be transmitted to the exercise activity monitoring system 12 (e.g., via wired or wireless connection) for storage (e.g., in the memory 88), processing (e.g., via the processing circuitry 86), and / or transfer to one or more external devices 36. In some embodiments, the lens seal 46 (e.g., seal body 180) may include wiring, tracing, or other electrical connections (e.g., embedded within the seal body 180) configured to communicatively couple the external sensors 34 to the exercise activity monitoring system 12 in an installed configuration of the exercise activity monitoring system 12 with the swim goggles 16.

[0056] FIG. 8 is a rear perspective view of an embodiment of a portion of the swim goggles 16 including an embodiment of the exercise activity monitoring system 12 disposed within the inner cavity 48 defined by the left lens 40. However, it should be appreciated that some or all of the embodiments of the exercise activity monitoring system 12 described herein may similarly be disposed within the inner cavity 56 of the right lens 42 (e.g., right eye goggle). The swim goggles 16 and the exercise activity and monitoring system 12 (e.g., sensor system) may be cooperatively considered a swim race data capture system 200 configured to enable the collection of data indicative of an activity and / or performance metric of a swimmer (e.g., user 122) participating in a swimming competition. In other embodiments, the exercise activity monitoring system 12, without the swim goggles 16, may be considered an embodiment of the swim race data capture system 200. In particular, the exercise activity and monitoring system 12 is configured to couple (e.g., mount, attached) to the swim goggles 16 (e.g., within the inner cavity 48 of the left lens 40) in a secured manner, such that the exercise activity and monitoring system 12 is fixed relative to the left lens 40 and therefore relative to a head of the swimmer wearing the swim goggles 16 (e.g., in an operational configuration of the swim goggles 16 and / or the exercise activity monitoring system 12). In this way, the exercise activity and monitoring system 12 may more reliably capture data indicative of one or more metrics indicative of a performance of the swimmer during a swimming event or activity. Moreover, in accordance with the present techniques, the exercise activity and monitoring system 12 does not include a display or other visual feedback output device configured to output light or other visual indication (e.g., toward the eye of the swimmer protected by the left lens 40) during the swimming activity (e.g., athletic competition, swimming race) of the swimmer. Therefore, embodiments of the exercise activity and monitoring system 12 described herein, which do not include a display or other visual feedback output device in an operational configuration of the swim race data capture system 200, may be utilized during certain athletic events (e.g., swimming races) having regulations or rules that do not permit the use of visual feedback devices (e.g., personal visual feedback devices) during participation in the athletic event.

[0057] As described in detail above, the exercise activity monitoring system 12 includes the housing 82 containing various components 80 of the exercise activity monitoring system 12. It should be appreciated that the housing 82 may include all and / or any combination of the components 80 described above. In some embodiments, the exercise activity monitoring system 12 may include additional or alternative components. For example, the housing 82 may include the one or more of the sensors 80, the IMU 96, the circuit board 104, the memory 88, and / or any other components 80 disposed within the housing 82. The housing 82 may be watertight or otherwise sealed to block ingress of water, liquid, moisture, contaminants, and / or other particles and thereby protect the components 80 disposed therein.

[0058] In the illustrated embodiment, the housing 82 is disposed within the inner cavity 48 of the left lens 40 and against a lateral edge 202 (e.g., peripheral edge) of the left lens 40. Thus, the exercise activity monitoring system 12 is disposed external to the central field of view 54 of a user wearing the swim goggles 16. In other words, the user wearing the swim goggles 16 with the exercise activity monitoring system 12 may not readily see, notice, or perceive the exercise activity monitoring system 12 when looking in a forward direction (e.g., forward direction 148, forward gaze direction) through the left lens 40, such as during swimming 24.

[0059] In the illustrated embodiment, all or substantially all of the components 80 (e.g., electrical components) of the exercise activity monitoring system 12 are disposed within the housing 82, and the housing 82 is disposed within the inner cavity 48. The inner cavity 48 is defined by the left lens 40 (e.g., eye goggle, eyepiece). The left lens 40 is an eye goggle 204 (e.g., left eye goggle) of the swim goggles 16, and the eye goggle 204 includes a front lens portion 206 and a skirt portion 208 (e.g., frame portion) extending from the front lens portion 206. For example, the skirt portion 208 may extend about a boundary 210 (e.g., outer boundary, circumference, outer edge, an entire boundary) of the front lens portion 206. The front lens portion 206 and the skirt portion 208 may cooperatively define the inner cavity 48 of the eye goggle 204. In an installed configuration of the exercise activity monitoring system 12 with the eye goggle 204, the housing 82 may engage with the front lens portion 206, the skirt portion 208, or both. For example, the housing 82 may engage with and / or at least partially abut an inner surface 212 (e.g., inner circumferential surface) of the skirt portion 208 extending about the inner cavity 48 at and / or adjacent the lateral edge 202 of the left lens 40. In some embodiments, the housing 82 may include an outer geometry 214 (e.g., lateral geometry, outer lateral edge, outer lateral surface, outer contour, curved geometry, arcuate contour, outward geometry, surface contour), and the inner surface 212 of the skirt portion 208 at the lateral edge 202 may include an inner geometry 216 (e.g., lateral geometry, inner contour, curved geometry, arcuate contour, surface contour) corresponding to the outer geometry 214 of the housing 82. In other words, the outer geometry 214 and the inner geometry 216 may generally match and / or mate with one another to enable engagement between the housing 82 and eye goggle 204 in an installed configuration of the exercise activity monitoring system 12.

[0060] In some embodiments, the housing 82 may also include an inward geometry 218 (e.g., inward lateral geometry, inward contour, inward surface, inward lateral edge) that is opposite the outer geometry 214 of the housing 82. In the illustrated embodiment, the inner geometry 218 of the housing 82 is substantially flat and generally faces a remainder of the inner cavity 48 (e.g., toward the central field of view 54). In this way, the housing 82 may be more visually inconspicuous to a user wearing the swim goggles 14 having the exercise activity monitoring system 12 disposed within the inner cavity 48.

[0061] As mentioned above, the housing 82 may be retained in a fixed position within the inner cavity 48 (e.g., against the inner surface 212 of the skirt portion 208) in any suitable manner. For example, the housing 82 may include an outer contour, edge, and / or geometry (e.g., outer geometry 214) configured to mate and / or engage with a corresponding inner contour, edge, and / or geometry 202 (e.g., inner geometry 216) of the eye goggle 204. In some embodiments, the housing 82 may include one or more retainers 220 (e.g., retention feature, coupler, attachment element, securement) configured to enable engagement between the housing 82 and the eye goggle 204, as well as retention of the housing 82 within the inner cavity 48 in a fixed position (e.g., relative to the eye goggle 204). For example, the one or more retainers 220 may include a tab, a tongue, a lip, an edge, a prong, a clip, a pin, a hook, a ridge, a protrusion, another suitable attachment feature, or any combination thereof. In some embodiments, the one or more retainers 220 may be configured to engage with (e.g., extend within) one or more complementary features (e.g., engagement receptacles 222) of the eye goggle 204. For example, the one or more retainers 220 may be configured to extend within one or more corresponding recesses, notches, grooves, crevices, and / or openings, which may be defined by the inner surface 212 of the skirt portion 208 and / or another portion of the eye goggle 204. Additionally or alternatively, the housing 82 may be configured to engage with the inner surface 212 and / or the front lens portion 206 via an interference fit, a friction fit, and / or a snap fit. In some embodiments, an adhesive may be applied to the housing 82, the inner surface 212 of the skirt portion 208, and / or front lens portion 206 of the eye goggle 204 to enable securement of the housing 82 within the inner cavity 48 in a fixed position.

[0062] As described herein, by maintaining a fixed position of the exercise activity monitoring system 12 relative to the swim goggles 16 (e.g., within the eye goggle 204) and the user (e.g., the head 126 of the user 122) during an activity (e.g., in an operational configuration of the eye goggle 204 and / or the exercise activity monitoring system 12), the exercise activity monitoring system 12 may more accurately and precisely detect and collect data indicative of activity parameters related to the activity. Further, as the exercise activity monitoring system 12 does not include any display or display system configured to provide feedback (e.g., visual feedback, project light perceivable by the user) to the user during the activity, any distraction to the user induced by the presence of the exercise activity monitoring system 12 may be substantially reduced and / or eliminated. Moreover, the exercise activity monitoring system 12 incorporating the disclosed techniques may comply with regulatory standards or qualifications, such as standards mandated by a governing entity or body for one or more activities, sports, events, competitions, and / or disciplines (e.g., a sanctioned or licensed race). Therefore, embodiments of the exercise activity monitoring system 12 described herein may be utilized during such regulated activities and / or athletic competitions (e.g., a swimming race) to capture data indicative a performance of a user of the exercise activity monitoring system 12 during the regulated activity and / or athletic competition while remaining in compliance with applicable regulations.

[0063] FIG. 9 is a rear perspective view of another embodiment of a portion of the swim goggles 16 including an embodiment of the exercise activity monitoring system 12 disposed within the inner cavity 48 defined by the eye goggle 204 of the left lens 40 (e.g., swim race data capture system 200). As described in detail above, the exercise activity monitoring system 12 includes the housing 82 (e.g., watertight housing) containing various components 80 of the exercise activity monitoring system 12. The illustrated embodiment includes certain elements and element numbers similar to those described above with reference to FIG. 8. For example, the exercise activity monitoring system 12 includes the outer geometry 214, which may correspond to (e.g., match) the inner geometry 216 of the skirt portion 208 of the eye goggle 204. Thus, the housing 82 may mate and / or engage with the skirt portion 208 of the eye goggle 204 to enable retention of the exercise activity monitoring system 12 in a fixed position within the inner cavity 48 in an installed configuration of the exercise activity monitoring system 12 with the left lens 40.

[0064] The illustrated embodiment of the exercise activity monitoring system 12 also includes a retention segment 240 (e.g., C-shaped ring, biasing ring, C-ring, retaining ring, brace, mounting segment, retention insert, retaining wedge) configured to enable fixed positioning of the exercise activity monitoring system 12 within the inner cavity 48 of the eye goggle 204. The retention segment 240 is configured to engage with the housing 82 and bias the housing 82 against the eye goggle 204 (e.g., skirt portion 208, inner geometry 216) to fixedly position the exercise activity monitoring system 12 within the inner cavity 48. In particular, the retention segment 240 is configured to bias the exercise activity monitoring system 12 against the inner geometry 214 of the inner surface 212 of the skirt portion 208, such that the outer geometry 214 of the housing 82 abuts the inner geometry 214 of the inner surface 212 (e.g., external to the central field of view 54). Additionally or alternatively, the retention segment 240 may bias the housing 82 at least partially against the front lens portion 206 to further secure the housing 82 in a fixed position with in the inner cavity 48. To this end, the retention segment 240 includes notches 242 formed at distal ends 244 of the retention segment 240. The notches 242 are configured to enable mating and / or engagement between the retention segment 240 and the housing 82. For example, the notches 242 may be configured to receive an edge 246 (e.g., vertex, corner) of the housing 82. Additionally, in an installed configuration within the inner cavity 48, the retention segment 240 extends away from the housing 82 and engages with (e.g., abuts) the inner surface 212 (e.g., inner circumferential surface) of the skirt portion 208 of the eye goggle 204. To this end, the retention segment 240 may have a C-shaped configuration. In some embodiments, the retention segment 240 may also engage with (e.g., abut) the front lens portion 206. In the installed configuration, the housing 82 and the retention segment 240 may cooperatively extend about (e.g., circumscribe) the central field of view 54 of a user wearing the swim goggles 16 having the left lens 40 with the housing 82 secured within the inner cavity 48. Indeed, as the retention segment 240 extends along the inner surface 212 of the skirt portion 208, the retention segment 240 may be substantially external to the central field of view 54 of the user wearing the swim goggles 16 with the exercise activity monitoring system 12.

[0065] In some embodiments, the retention segment 240 may be formed from a flexible and / or semi-flexible material (e.g., elastically deformable material, pliable material), such as a semi-flexible plastic, silicone, foam, rubber, a polymer, a composite material, neoprene, another suitable material, or any combination thereof. As a result, the retention segment 240 may be at least partially elastically deformed to facilitate installation of the exercise activity monitoring system 12 within the inner cavity 48 of the eye goggle 204 and removal of the exercise activity monitoring system 12 from the inner cavity 48 of the eye goggle 204. Further, the flexible or semi-flexible characteristic of the retention segment 240 may enable positioning of the retention segment 240 within inner cavity 48 against the inner surface 212 to bias the housing 82, which may be formed from a rigid material (e.g., rigid plastic), against the inner surface 212 (e.g., inner geometry 214) of the skirt portion 208, thereby facilitating fixed positioning of the exercise activity monitoring system 12 within the inner cavity 48 of the eye goggle 204. In some embodiments, the retention segment 240 may be an individual component separate from the housing 82 and configured to abut and engage with the housing 82 in an installed configuration within the inner cavity 48. In other embodiments, the retention segment 240 may be attached to the housing 82, such as via an adhesive, a molding process, or other suitable technique, such that the housing 82 and the retention segment 240 remain coupled (e.g., attached, fixed, secured, directly coupled) to one another in installed and uninstalled configurations.

[0066] FIG. 10 is a rear perspective view of another embodiment of a portion of the swim goggles 16 including an embodiment of the exercise activity monitoring system 12 disposed within the inner cavity 48 defined by an embodiment of the eye goggle 204 (e.g., left lens 40). The eye goggle 204 may be similar to embodiments of the eye goggle 204 (e.g., left lens 40) described above. For example, the eye goggle 204 may have the front lens portion 206 and the skirt portion 208 extending from the front lens portion 206 to cooperatively define the inner cavity 48. The skirt portion 208 (e.g., frame portion) may also include the inner surface 212 (e.g., inner circumferential surface) generally circumscribing the inner cavity 48. The eye goggle 204 may further include other features similar to those discussed above, such as the inner geometry 214 of the inner surface 212.

[0067] As shown, the exercise activity monitoring system 12 (e.g., sensor system) may also have elements similar to those discussed above, such as an embodiment of the housing 82 (e.g., watertight housing) configured to contain and enclose components 80 of the exercise activity monitoring system 12. In the illustrated embodiment, the exercise activity monitoring system 12 defines a generally annular (e.g., ring-shaped) configuration. For example, the housing 82 may define an annular configuration (e.g., annular geometry) configured to extend along the inner surface 212, including the inner geometry 214, of the eye goggle 204. To this end, the housing 82 may be formed from a semi-flexible material (e.g., elastically deformable material, pliable material), which may include a semi-flexible plastic, silicone, rubber, a polymer, a composite material, neoprene, another suitable material, or any combination thereof. As shown, one or more components 80 of the exercise activity monitoring system 12 may be disposed (e.g., spaced, arrayed) throughout the annular configuration of the housing 82.

[0068] The housing 82 may also have one or more natural or resting geometries and / or dimensions (e.g., width, diameter, length) that is equal to or slightly (e.g., 1 percent, 2 percent, 3 percent, 4 percent, 5 percent, 7 percent, 10 percent) greater or larger than a corresponding geometry and / or dimension of the inner cavity 48. In this way, the housing 82 may at least partially elastically deform to match, engage, and / or abut against the inner surface 212 of the skirt portion 208 (e.g., via an interference fit, via a friction fit) in an installed configuration of the exercise activity monitoring system 12 within the inner cavity 48 of the eye goggle 204. In some embodiments, the housing 82 may be configured to abut an entire circumference or substantially an entire circumference of the inner surface 212 (e.g., extending about the central field of view 54) in the installed configuration of the exercise activity monitoring system 12. The housing 82 may also be configured to at least partially abut a portion of the front lens portion 206 (e.g., an inward surface 260) facing and / or at least partially defining the inner cavity 48.

[0069] One or more of the components 80 disposed within the housing 82 may also be formed from a semi-flexible and / or elastically deformable material to enable temporary, elastic deformation of the exercise activity monitoring system 12. Therefore, the housing 82 and one or more components 80 disposed therein may be at least partially elastically deformed to facilitate installation of the exercise activity monitoring system 12 within the inner cavity 48 of the eye goggle 204 and removal of the exercise activity monitoring system 12 from the inner cavity 48 of the eye goggle 204 (e.g., left lens 40). In other words, the housing 82 may be at least partially elastically deformed and wedged into the inner cavity 48 and into engagement (e.g., abutment) with the inner surface 212 of the skirt portion 208 and / or the front lens portion 206. In some embodiments, the circuit board 104 may be formed from a semi-flexible and / or elastically deformable material, and other components 80 (e.g., IMU 96, accelerometer 98, gyroscope 100, sensors 84, etc.) may be disposed on the circuit board 104.

[0070] While the housing 82 containing the components 80 (e.g., electronic components) disposed therein may define the annular configuration of the exercise activity monitoring system 12, in other embodiments the housing 82 may include a first portion 262 (e.g., first housing portion, electronics portion, sensor portion) containing the components 80 of the exercise activity monitoring system 12 (e.g., sensor system) therein and a second portion 264 (e.g., second housing portion, support portion, retention portion) that does not contain one or more of the components 80 therein. The first portion 262 and the second portion 264 may each have a generally C-shaped configuration (e.g., arcuate configuration, arcuate geometry) that cooperatively define the annular configuration of the exercise activity monitoring system 12, as shown. In some embodiments, the first portion 262 and the second portion 264 may be formed from the semi-flexible and / or elastically deformable material. In other embodiments, different semi-flexible and / or elastically deformable materials may be utilized to form the first portion 262 and the second portion 264. In any case and in accordance with the present techniques, the first portion 262 and the second portion 264 may be integrally formed (e.g., as a single piece) to define the housing 82. The first portion 262 and the second portion 264 may be integrally formed with one another via a molding process, a casting process, another suitable technique, or any combination thereof.

[0071] As similarly described above, the housing 82 having the annular configuration may be positionally fixed (e.g., wedged) within the inner cavity 48 of the eye goggle 204 via an interference fit and / or a friction fit. The annular configuration of the housing 82 in the illustrated embodiment further enables substantially reduced visual obstruction for a user wearing the swim goggles 16 having the exercise activity monitoring system 12 installed therein. Indeed, the housing 82 with the annular configuration may be substantially external to the central field of view 54 of the user wearing the swim goggles 16, as shown, and may not be perceivable by the user when looking through the front lens portion 206 (e.g., in the forward direction 148, in a forward gaze direction). The exercise activity and monitoring system 12 also does not include a display or other visual feedback output device configured to output light or other visual indication (e.g., toward the eye of a swimmer wearing the swim goggles 16, output or project light from the housing 82) during a swimming activity (e.g., athletic competition, swimming race) of the swimmer. Therefore, use and operation of the exercise activity and monitoring system 12 by a swimmer wearing the swim goggles 16 with the exercise activity and monitoring system 12 installed therein may comply with regulations or rules of certain athletic events (e.g., swimming races) that do not permit the use of visual feedback devices (e.g., personal visual feedback devices) during participation in the athletic event. The exercise activity and monitoring system 12 incorporating the present techniques may therefore enable the detection and collection of data indicative of activity and / or performance metrics (e.g., head position) of the swimmer during participation in the athletic event (e.g., swimming race, sanction swimming event), and the data may be subsequently utilized to evaluate the performance of the swimmer in the athletic event, as well as facilitate performance improvements for the swimmer in future athletic events.

[0072] FIGS. 11-14 illustrate another embodiment of a portion of the swim goggles 16 including an embodiment of the exercise activity monitoring system 12 (e.g., swim race data capture system 200) retained within an embodiment of one of the eye goggles 204 (e.g., left lens 40) of the swim goggles 16, in accordance with the present techniques. Specifically, FIG. 11 is a side view of the eye goggle 204 having the exercise activity monitoring system 12, FIG. 12 is a rear axial view of the eye goggle 204 having the exercise activity monitoring system 12, FIG. 13 is a rear perspective view of the eye goggle 204 having the exercise activity monitoring system 12, and FIG. 14 is a perspective side view of the eye goggle 204 having the exercise activity monitoring system 12. FIGS. 11-14 are discussed concurrently below. Additionally, to facilitate the following discussion, the eye goggle 204, the exercise activity monitoring system 12, and other components may be described with reference to a longitudinal axis or direction 300 (e.g., viewing axis, forward direction), a vertical axis or direction 302, and a lateral axis or direction 304.

[0073] As similarly described above, the eye goggle 204 may have the front lens portion 206 defining the central field of view 54 and the skirt portion 208 (e.g., frame portion) extending from the front lens portion 206. The eye goggle 204 may further include other features similar to those discussed above, such as the inner geometry 214 of the inner surface 212. In some embodiments, the front lens portion 206 may have a generally flat and / or planar geometry extending along the vertical axis 302 and the lateral axis 304. In other embodiments, the front lens portion 206 may include one or more curved, arcuate, geometric, or other contoured portions. In any case, the front lens portion 206 generally defines the central field of view 54 in which a user (e.g., a swimmer) wearing the swim goggles 16 may look through the front lens portion 206 (e.g., in a direction generally along the longitudinal axis 300 and / or in the forward direction 148 and / or in a forward gaze direction). As shown, the front lens portion 206 has a generally oval or oblong shape or configuration (e.g., oblong geometry), but other embodiments of the eye goggle 204 may include the front lens portion 206 with another suitable shape, geometry, or configuration.

[0074] The skirt portion 208 extends from the boundary 210 (e.g., outer edge, oblong geometry) of the front lens portion 206. Specifically, the skirt portion 208 may flare outwardly and / or away from the front lens portion 206, and various sections or regions of the skirt portion 208 at least partially along the longitudinal axis 300 (e.g., in the backward direction 150), the vertical axis 302 (e.g., in the upward direction 136, in the downward direction 138), and / or along the lateral axis 304 (e.g., in the left direction 142, in the right direction 144). Indeed, the skirt portion 208 may extend about an entirety of the boundary 210 of the front lens portion 206 to cooperatively define the inner cavity 48 of the eye goggle 204. As similarly described above, the eye goggle 204 may also include a sealing portion 306 (e.g., sealing edge, sealing interface) extending along and / or from the skirt portion 208 (e.g., opposite the front lens portion 206. The sealing portion 306 is configured to contact a face of a user (e.g., swimmer) wearing the swim goggles 16 and extend about (e.g., circumscribe) an eye (e.g., a single eye) of the user to create a sealing engagement between the eye goggle 204 and the face of the user with the eye of the user exposed to the inner cavity 48 defined by the eye goggle 204. In this way, the eye goggle 204 may block ingress of water into the inner cavity 48 and facilitate suitable vision of the user wearing the swim goggles 16 during the swimming 24 activity (e.g., swimming race). The sealing portion 306 may be formed from the same material as the skirt portion 208, or the sealing portion 306 may include an additional material, such as rubber, foam, another compressible sealing material, or any other suitable material, applied to the eye goggle 204 along an edge (e.g., circumference) of the sealing portion 306.

[0075] The eye goggle 204 also defines a pocket 308 (e.g., recess, cavity, configured to receive (e.g., accommodate) and / or retain the exercise activity monitoring system 12 (e.g., housing 82) therein. In particular, the pocket 308 may be formed in (e.g., integrally formed in) the skirt portion 208 of the eye goggle 204. The pocket 308 extends from the inner surface 212 of the skirt portion 208 and generally along the lateral axis 304 (e.g., in the left direction 142) in the illustrated embodiment. However, it should be appreciated that the pocket 308 also at least partially extends along the longitudinal axis 300 and the vertical axis 302 to define a volume or space configured to receive the housing 82 of the exercise activity and monitoring system 12. In other embodiments, the eye goggle 204 of the right lens 42 may include the pocket 308 configured to receive and / or retain the exercise activity monitoring system 12 (e.g., housing 82) therein. An embodiment of the pocket 308 formed in the right lens may extend from the inner surface 212 of the skirt portion 208 along the lateral axis 304 and in the right direction 144, as well as at least partially extends along the longitudinal axis 300 and the vertical axis 302.

[0076] To enable retention of the housing 82 within the pocket 308 and fixed positioning of the housing 82 relative to the eye goggle 204, and therefore fixed positioning of the housing 82 relative to a head of a wearer (e.g., swimmer) of the swim goggles 16, the housing 82 may have one or more geometries (e.g., contours, surfaces) that correspond to (e.g., match, mate with, engage with, abut) one or more geometries of the eye goggle 204 (e.g., skirt portion 208) defining the pocket 308. More specifically, the housing 82 may include a plurality of outer surfaces 310, and each outer surface 310 may have a respective geometry (e.g., shape, contour, curvature, angle, dimension) that is configured to engage with (e.g., mate, abut, contact) a respective geometry (e.g., shape, contour, curvature, angle, dimension) of a corresponding inner surface 312 of a plurality of inner surfaces 312 of the eye goggle 204 (e.g., skirt portion 208) defining the pocket 308. Each outer surface 310 of the housing 82 may abut and / or engage with a corresponding one of the inner surfaces 312 defining the pocket 308 in the installed configuration of the housing 82 within the pocket 308. The plurality of outer surfaces 310 and the plurality of inner surfaces 312 may extend along the longitudinal axis 300, the vertical axis 302, the lateral axis 304, or any combination thereof. The outer surfaces 310 of the housing 82 may engage with the inner surfaces 312 defining pocket 308, such that the eye goggle 204 may capture the housing 82 within the pocket 308, and movement of the housing 82 within the pocket 308 along the longitudinal axis 300, the vertical axis 302, and the lateral axis 304 may be restricted, blocked, and / or prevented. In this way, a position of the housing 82 within the pocket 308 may be fixed relative to the eye goggle 204 in the installed configuration of the exercise activity monitoring system 12.

[0077] In some embodiments, the housing 82 may include one or more features configured to enable retention and fixed positioning of the housing 82 within the pocket 308 in the installed configuration. For example, the housing 82 may include one or more embodiments of the retainers 220 described above, and the skirt portion 208 may include one or more of the engagement receptacles 222 within the pocket 308 that are configured to receive and engage with the retainers 220 to enable retention of the housing 82 within the pocket 308 via a snap fit. Additionally or alternatively, one or more of the retainers 220 may extend within and / or otherwise engage with one or more of the engagement receptacles 222 and may instead engage with (e.g., abut) one or more of the inner surfaces 312 to enable retention of the housing 82 within the pocket 308 via a friction fit and / or an interference fit. In the illustrated embodiment, the housing 82 includes a protrusion 314 extending from one of the outer surfaces 310 of the housing 82 along the longitudinal axis 300. The protrusion 314 may engage with one of the inner surfaces 312 defining the pocket 308 to enable retention and fixed positioning of the housing 82 within the pocket 308.

[0078] As will be appreciated, the pocket 308 may be a volume or space that extends from and is fluidly coupled to the inner cavity 48 defined by the eye goggle 204. The housing 82 may therefore be positioned within the pocket 308 via the inner cavity 48 (e.g., translated along the lateral axis 304 in the left direction 142 in the illustrated embodiment). The pocket 308 may be configured to receive a portion or an entirety of the housing 82. Similarly, in an installed configuration of the housing 82 within the pocket 308, the housing 82 may be accessible via the inner cavity 48 to enable removal of the housing 82 from the pocket 308 (e.g., to charge the power supply 90, to transfer data stored on the memory 88 to one of the external devices 36, to position the housing 82 within the pocket 308 of another embedment of the eye goggle 204, etc.).

[0079] As previously described, the housing 82 is configured to be positioned and retained (e.g., positionally fixed) within the eye goggle 204, such that the housing 82 is generally external to the central field of view 54 of a user wearing the swim goggles 16 and looking through the front lens portion 206 (e.g., along the longitudinal axis 300, in the forward direction 148, in a forward gaze direction). In the illustrated embodiment, the housing 82 may be offset (e.g., substantially offset, entirely offset) from the front lens portion 206 in the installed configuration of the housing 82 within the pocket 308. For example, as shown in FIG. 12, the pocket 308 may be formed within the skirt portion 208 of the eye goggle 204, such that the housing 82 positioned within the pocket 308 does not overlap with the front lens portion 206 along the longitudinal axis 300. The housing 82 is external to (e.g., does not overlap with) the boundary 210 of the front lens portion 206 along the longitudinal axis 300. In other words, the housing 82 may not extend within a projection of the boundary 210 (e.g., outer edge of an oblong geometry) and / or front lens portion 206 (e.g., oblong shape) along the longitudinal axis 300. In this way, the housing 82 disposed and retained within the pocket 308 may be substantially or entirely external to the central field of view 54 of a wearer of the swim goggles 16, and the wearer may not perceive and / or otherwise be distracted by the presence of the exercise activity monitoring system 12 disposed within the eye goggle 204 (e.g., during swimming 24, during a swim race, in an operational configuration of the exercise activity monitoring system 12 disposed within the eye goggle 204 and the swim goggles 16 worn by a swimmer).

[0080] Furthermore, in accordance with the present techniques, the exercise activity and monitoring system 12 illustrated in FIGS. 11-14 also does not include a display or other visual feedback output device configured to output light or other visual indication (e.g., toward the eye of a swimmer wearing the swim goggles 16, output or project light from the housing 82) during a swimming activity (e.g., athletic competition, swimming race) of the swimmer. Therefore, use and operation of the exercise activity and monitoring system 12 by a swimmer wearing the swim goggles 16 with the exercise activity and monitoring system 12 installed therein may comply with regulations or rules of certain athletic events (e.g., swimming races) that do not permit the use of visual feedback devices (e.g., personal visual feedback devices) during participation in the athletic event. The exercise activity and monitoring system 12 incorporating the present techniques may therefore enable the detection and collection of data indicative of activity and / or performance metrics (e.g., head position) of the swimmer wearing the swim goggles 16 with the exercise activity monitoring system 12 during participation in the athletic event (e.g., swimming race, sanction swimming event), and the data may be subsequently utilized to evaluate the performance of the swimmer in the athletic event, as well as facilitate performance improvements for the swimmer in future athletic events.
