HAPTIC FEEDBACK DEVICE AND METHOD CROSS-REFERENCE TO RELATED APPLICATIONS

[0003] The concept of applying forces, vibrations and / or motions to a user for improved immersion in media content and / or improved user experience is known as haptic feedback. Various devices may be configured to provide haptic feedback when, for instance, playing a video game, watching a movie or operating a handheld device. Such devices may include, for example, a mouse, a keyboard, a controller, a phone or other handheld device, and so on.
[0004] Attempts have also been made to integrate user feedback into seating surfaces, for example a seat equipped with mechanical actuators or vibration motors that create sensations for a user in concert with the media content displayed on a screen. For instance, vibrations in the backrest or seating surface of a seat may be generated to immerse the user in the media content.
[0005] Traditional haptic feedback devices such as vibration motor systems are typically rigidly mounted, offering uniform haptic feedback across the entire structure. These mountings do not offer the ability to selectively control spatial distribution of vibrational energy using a single actuator. Thus, there remains a need for improved haptic feedback technology offering additional flexibility to provide localized feedback in addition to transmitting vibrations throughout the entire system.SUMMARY

[0047] This present disclosure is directed to systems and methods that are capable of creating representative sensations that include all the elements of a haptic interaction by using a haptic element. The haptic element as described herein may include, for example, a seat providing haptic feedback, or haptic vibrations, in the seat or back areas. Such a seat may include, for example, a video game chair, an aircraft seat, a home theatre seat, a cinema seat, etc.
[0048] Now referring to Fig. 1 , there is shown a schematic block diagram of a haptic element 10, in accordance with an embodiment. In the shown embodiments, the haptic element 10 is a vibration motor system. It is understood, however, that other types of haptic elements which can provide other types of haptic feedback (i.e., other than or in addition to vibrations) are contemplated. The depicted haptic element 10 includes a controller 12, at least one actuator 14, and a haptic feedback transmitter for transmitting haptics generated by the actuator 14 to the user. The controller 12 of the haptic element 10 is in communication with a media content source 16. The haptic element 10 has a housing 18 in which the actuator(s) 14 are installed and in which, in certain embodiments, the controller 12 may also be installed. Insome embodiments, the housing 18 is omitted. The haptic element 10 may be powered by any suited power source, such as a battery or from a DC or AC external source. In operation, the controller 12 receives signals from the media content source 16 indicative of an “event” in the media content, and in response, provides a control signal to the actuator 14. For example, a character controlled in a video game may contact an object in the video game. The subsequently issued control signal can include instructions regarding a specific intensity and / or frequency at which the actuator 14 is to vibrate to replicate the sensation of contacting the object.
[0049] It will be appreciated that the type of actuator 14 may vary. However, in a particular embodiment the actuator 14 is a vibration actuator, and be selected, but not limited to, one of an eccentric rotating mass (ERM), a linear resonant actuator (LRA), a voice coil, a piezo haptic actuator, a solenoid haptic actuator, an ultrasonic transducer, an impact actuator and other actuators of the like. The actuator 14 may also be a deformation actuator, a force feedback actuator, and / or a motion actuator. Regardless of actuator type, the actuator 14 is configured to excite mechanical motion of the end effector 22 rather than to define the spatial distribution of the resulting haptic effect. In this regard, the selective delivery of localized or systemic haptic feedback arises primarily from the mechanical coupling characteristics between the actuator 14 and the haptic feedback transmitter, including the relative mass, compliance, and coupling behavior of the first and second end effector portions, rather than from the specific construction or operating principle of the actuator itself.
[0050] Accordingly, different actuator technologies and drive signals can be employed to excite substantially similar mechanical response modes of the haptic feedback transmitter, provided that the actuator 14 is capable of generating vibrational energy within the operating range of the mechanical system. In some embodiments, the actuator 14 is be driven with broadband, composite, or time-varying excitation signals, while the mechanical structure of the haptic feedback transmitter functions to selectively transmit, attenuate, or spatially redistribute the vibrational energy delivered to the haptic feedback region.
[0051] The controller 12 may be installed inside the housing 18 of the haptic element 10, or exterior to the haptic element 10. For instance, the controller 12 may be installed in the haptic element 10 and have means to wirelessly communicate with another computing device having the media content source 16. In some other embodiments, the haptic element 10 may include both the controller 12 and the media content source 16. In some embodiments, thecontroller 12 of the haptic element 10 is coupled to another computing device having the media content source 16 via a USB cord or other wired means of the like. In some embodiments, the haptic element 10 is positioned in a device configured to be in contact with a user, such as a seat. Exemplary seats include a video game chair, a pilot’s seat or other aircraft seat, a home theatre seat, a cinema seat, an office chair, a simulator seat, an automobile seat (e.g., a driver’s seat) or other vehicle seat, etc. The haptic element 10 is positioned inside the seat in a suspended fashion (e.g., in a free-floating framework such that the haptic element 10 is decoupled from a given seating surface) and is configured to provide haptic feedback to the seat or back areas. The haptic element 10 is configured for selectively decoupling under certain conditions to vary the area of the seat being subjected to the vibrations. Other devices configured to be in contact with a user may be contemplated. For instance, in an embodiment, the device is a bed and the one or more haptic elements are positioned in a body contacting surface of the device. In another embodiment, the device is an article of clothing such as a vest, shirt, pants, cuff, etc., and the one or more haptic elements are positioned in a body contacting surface of the device. Yet other device types are contemplated.
[0052] In seating implementations, the haptic element 10 is mountable within or beneath one or more compliant layers of the seat, including but not limited to foam cushions, spacer fabrics, trim covers, or suspension elements, such that the haptic element 10 is mechanically decoupled from rigid structural components of the seat frame. In such configurations, the first and second operating modes of the haptic element 10 may be perceived by a user as differences in spatial extent, distribution, or character of the haptic feedback rather than as discrete mechanical transitions. The compliant materials of the seat may further act in combination with the haptic element 10 to attenuate or distribute vibrational energy, thereby contributing to the localized or systemic nature of the haptic feedback. Transitions between operating modes may occur without perceptible mechanical switching, audible artifacts, or abrupt changes in surface compliance, such that the change in haptic effect remains substantially imperceptible to the user aside from the intended variation in haptic sensation.
[0053] Referring to Figs. 2A and 3, the depicted the haptic element 10 includes, within a given haptic feedback region 20, an actuator 14 mounted in the housing 18 (shown in Fig. 1). The haptic feedback region 20 is located in a device configured to be in contact with a user, such as a seat. It is understood that a given region of a seat may include a plurality of haptic elements 10, each positioned in a distinct haptic feedback region 20. The actuator 14 acts onthe haptic feedback transmitter, illustratively end effector 22, in such a manner as to generate a haptic feedback that is transmitted to the user via this end effector 22. The actuator 14 is partially decouplable from the end effector 22. By partially decouplable, it is understood that the actuator 14 is adapted to selectively transmit the haptic vibrations to some or all of the haptic feedback region 20 based on the selected operating mode governing the connection between the actuator 14 and the end effector 22. As will be discussed in further detail below, the haptic element 10 is configured for operating in in a first operating mode, also referred to as a decoupled, localized or isolated haptic mode, in which haptic feedback is provided to an isolated portion (referred to below as a first haptic feedback region 20a) of the given haptic feedback region 20, and in a second operating mode, also referred to as a general or systemic haptic mode, in which haptic feedback is provided to a majority of the given haptic feedback region 20 (referred to below as a second haptic feedback region 20b). As used herein, the term “majority” refers to a portion of the given haptic feedback region 20 being greater than 50% of the entire region 20 and up to an entirety (i.e., 100%) of the region 20.
[0054] In some cases, a given haptic feedback region 20 extends across an entire seating surface (e.g., a seat or a back area). Stated differently, a single actuator 14 is configured to selectively provide haptic feedback to an entire seating surface of a given seat. Referring now to Fig. 2B, in other cases, a seating surface 21 is subdivided into multiple haptic feedback regions 20, 120, 220 as discussed above. In such cases, the haptic element 10 includes multiple actuators 14, 114, 214, with each actuator 14, 114, 214 configured to selectively provide haptic feedback to different portions (i.e., regions 20, 120, 220) of the seating surface 21 . Various layouts for the multiple actuators may be contemplated. Other arrangements are contemplated for delivering haptic feedback to the user.
[0055] In some cases, the end effector 22 is located within a seating surface of a given seat and thus does not directly contact the user. For instance, in some embodiments, the haptic element 10 is suspended within a seating surface of a given seat. In other cases, the end effector projects or extends through the seating surface, thereby directly contacting the user. As shown in Fig. 2A, the haptic feedback region 20 includes a first haptic feedback region 20a, also referred to as an isolated portion of the haptic feedback region 20, and a second haptic feedback region 20b, also referred to as a remainder of the haptic feedback region 20. In the depicted embodiment, the haptic feedback region 20 has a circular planar shape, with the second haptic feedback region 20b disposed radially outwardly of the firsthaptic feedback region 20a in a concentric arrangement. Other configurations (e.g., more than two haptic feedback regions, and arranged in various relative arrangements) remain possible.
[0056] Referring additionally to Figs. 3-6, the end effector 22 includes a first end effector portion 22a, also referred to as an inner end effector portion, and a second end effector portion 22b, also referred to as an outer end effector portion, disposed radially outwardly of the first end effector portion 22a. The first end effector portion 22a is configured for transferring the haptic vibrations to the first haptic feedback region 20a, while the second end effector portion 22b is configured for transferring the haptic vibrations to the second haptic feedback region 20b. In the shown case, the first and second end effector portions 22a, 22b are coupled to one another via a spiral spring 24 integrated into the second end effector portion 22b. Alternatively, in some embodiments the spiral spring 24 is distinct from and couplable to the second end effector portion 22b (as discussed in further detail below). In the shown case, the spiral spring 24 is configured for selectively and passively decoupling the first and second end effector portions 22a, 22b from one another, as will be discussed in further detail below. Other connections between the end effector portions 22a, 22b configured for passive decoupling of the first and second end effector portions 22a, 22b may be contemplated, for instance compliant mechanisms or bistable configurations. In some embodiments, a leaf spring or a non-spiral spring (i.e., a rotationally symmetric spring) is provided in place of the spiral spring 24. It is understood that these examples of spring arrangements are exemplary, and other spring arrangements are contemplated.
[0057] In the shown case, the spiral spring 24 integrally formed with the second end effector portion 22b and is configured for selectively allowing the haptic feedback applied to the first end effector portion 22a to be transferred to the second end effector portion 22b. For instance, in the first operating mode, the tensile forces due to the stiffness of the spiral spring 24 oppose the vibrations from the first end effector portion 22a and resist the movement thereof so that the second end effector portion 22b remains static with little to no vibration, while in the second operating mode, the intensity and / or frequency of the vibrations cause the first and second end effector portions 22a, 22b to resonate and vibrate together, with the spiral spring 24 magnifying the vibrations, for instance in a resonant mode or band. In this regard, the spiral spring 24 defines an adjustable mechanical coupling between the first end effector portion 22a and the second end effector portion 22b, the coupling being defined by a predetermined stiffness, damping, and effective mechanical impedance. The first and second end effector portions 22a, 22b can further differ in mass and inertial properties, such thatvibrational energy generated by the actuator 14 is preferentially confined to the first end effector portion 22a under certain excitation conditions. As such, the haptic element 10 is configured for operating in a first operating mode in which the haptic vibrations from the actuator 14 are transferred only to the first haptic feedback region 20a (via first end effector portion 22a) and a second operating mode in which the haptic vibrations from the actuator 14 are transferred to the entire haptic feedback region 20 (i.e., first and second haptic feedback regions 20a, 20b) via first and second end effector portions 22a, 22b, respectively. Stated differently, in the second operating mode, the actuator 14 is configured to resonate the entire end effector 22 when operating at specific intensity levels and / or frequencies. The first operating mode may be referred to as a localized haptic feedback mode, whereas the second operating mode may be referred to as a systemic haptic feedback mode. In some embodiments, the actuator 14 vibrates at lower intensities in the first operating mode and higher frequencies in the second operating mode. The haptic element 10 shown in FIGS. 2A and 3-6 is configured for selectively delivering localized or systemic haptic feedback in a passive manner. In particular, an extent of haptic feedback delivery by the actuator 14 is passively managed by the behaviour of the spiral spring 24 (or other like connective member) in view of the intensity and / or frequency of the vibrations emitted by the actuator 14. In other cases, management of the extent of the haptic feedback delivery is managed actively, as discussed in further detail below. In embodiments, the transition between the first operating mode and the second operating mode is continuous rather than binary, such that partial coupling between the first and second end effector portions 22a, 22b occurs over a range of excitation amplitudes and / or frequencies. Accordingly, in such cases, the spatial extent of the haptic feedback delivered to the haptic feedback region 20 is progressively varied as a function of the excitation signal provided to the actuator 14, without requiring discrete mechanical switching or additional actuators.
[0058] In the shown case, the actuator 14 includes a shaft 14a extending from a first end 14b to a second end 14c. The shaft 14a is shown to be hollow and have a square-shaped cross-section, although other configurations are contemplated. The first and second ends 14b, 14c have greater thicknesses than the remainder of the shaft 14a, and ribbing 14d is provided partway along a length of the shaft 14a. Covers 14e, 14f are illustratively provided to cover the hollow interior of the shaft 14a at the first and second ends 14b, 14c, respectively. The first end is received in a slot 22a1 on an underside of the end effector 22. In the shown case, the slot 22a1 is formed within a protrusion 22a2 protruding from the underside of the secondend effector portion 22b, with the slot 22a1 aligning with the first end effector portion 22a. Other slot configurations are contemplated. Various attachment means between the actuator 14 and first end effector portion 22a are contemplated in a manner to transmit vibrations from the actuator 14 to the first end effector portion 22a.
[0059] The actuator 14 is configured to transmit vibrations to the end effector 22, for instance upon receiving instructions to do so from the controller 12. The instructions include a targeted haptic feedback area of the haptic feedback region 20: an isolated portion of the haptic feedback region 20 (i.e., first haptic feedback region 20a) or a majority of the haptic feedback 20 (i.e., both first haptic feedback region 20a and second haptic feedback region 20b). Upon receipt of these instructions, the actuator 14 is configured to generate haptic feedback (i.e., vibrations) at a specific frequency and intensity in order to selectively transmit the vibrations, in coordination with the spiral spring 24 or other like connective element, to only the first end effector portion 22a or to both the first and second end effector portions 22a, 22b. The first and / or second end effector portions 22a, 22b are thus configured to transmit the haptic feedback to the desired portion(s) of the haptic feedback region 20.
[0060] While not shown in Figs. 2A and 3-6, various powering means for the actuator 14 are contemplated. For instance, in an exemplary seat, a plurality of actuators 14 are each electrically coupled to a central power source such as a battery mounted inside the seat or to the electric grid. Alternatively, each actuator 14 can be provided with its own power source, for instance a battery stored within a housing 18. Other power supplies are contemplated.
[0061] Referring now to Figs. 7-11, another embodiment of a haptic element 10’ is shown. Unless otherwise specified, like reference numerals refer to like elements, with the addition of an apostrophe.
[0062] As was the case for the haptic element 10 shown in Figs. 2A and 3-6, the haptic element 10’ is configured for selectively providing haptic feedback to some or all of a given haptic feedback region 20’ in a device to be in contact with a user, such as a seat. The haptic element 10’ is said to be configured to provide active decoupling of the first and second end effector portions 22a’, 22b’ via an active decoupling mechanism such as an electromagnetic actuator, a solenoid or clutch (not shown). For instance, an exemplary active decoupling mechanism includes a solenoid arranged to engage with a rubber top or other like coupling element coupled to the end effector 22’, whereby the solenoid pushes against the rubber topto actively couple or decouple the first and second end effector portions 22a’, 22b’. Other configurations for the active decoupling mechanism are contemplated, for instance an electromagnetic latch selectively activatable and deactivatable to couple or decouple to actively couple or decouple the first and second end effector portions 22a’, 22b’. One or more connections 26’ operatively connect the first end effector portion 22a’ to the second end effector portion 22b’, the connection^) 26’ also coupled to the active decoupling mechanism for selectively decoupling the second end effector portion 22b’ from the first end effector portion 22a’. In some cases, the connection(s) 26’ are integrated with the active decoupling mechanism. In some cases, the active decoupling mechanism is controlled, via instructions received from the controller 12, in real-time to provide dynamic switching between systemic and localized haptic effects.
[0063] In particular, the actuator 14’ is configured to transmit vibrations to the end effector 22’, for instance upon receiving instructions to do so from the controller 12. The instructions include a targeted haptic feedback area of the haptic feedback region 20’: an isolated portion of the haptic feedback region 20’ (i.e., first haptic feedback region 20a’) or a majority of the haptic feedback 20’ (i.e., both first haptic feedback region 20a’ and second haptic feedback region 20b’). Upon receipt of these instructions, the actuator 14’ is configured to generate haptic feedback (i.e., vibrations) at a specific frequency and intensity in order to selectively transmit the vibrations, in coordination with the active decoupling mechanism, to only the first end effector portion 22a’ or to both the first and second end effector portion 22a’, 22b’. The first and / or second end effector portions 22a’, 22b’ are thus configured to transmit the haptic feedback to the desired portion (or majority) of the haptic feedback region 20’.
[0064] In the shown case, a housing 18’ is provided to cover or surround the actuator 14’. In particular, a first housing portion 18a’ covers a lower portion of the actuator 14’, while a second housing portion 18b’ covers an upper portion of the actuator 14’. Other housing 18’ configurations are contemplated. In addition, in the shown case, an annular support member 22c’ is received on an underside of the second end effector portion 22b’, although this is optional. The depicted protrusion 22a2’ forming the slot 22a1’ is illustratively distinct form the end effector 22’. In other cases, the protrusion 22a2’ is integral with one of the first end effector portion 22a’ or second end effector portion 22b’.
[0065] Referring now to Figs. 12-13, another embodiment of a haptic element 10” is shown. Unless otherwise specified, like reference numerals refer to like elements, with the addition of a double apostrophe.
[0066] As was the case for the haptic elements 10, 10’ shown in Figs. 2A and 3-6 and 7-11 , the haptic element 10” is configured for selectively providing haptic feedback to some or all of a given haptic feedback region in a device to be in contact with a user, such as a seat. As was the case with the haptic element 10 shown in Figs. 2A and 3-6, the depicted haptic element 10” is configured for providing passive decoupling of the first and second end effector portions 22a”, 22b” via a spiral spring 24” coupled to the end effector 22”, illustratively to an underside of the second end effector portion 22b” (although other mounting configurations are contemplated). Stated differently, in the shown case, the spiral spring 24” is a distinct component than the end effector 22”, illustratively having a disk-like body, that is configured for coupling with the end effector 22” to provide passive decoupling of the first and second end effector portions 22a”, 22b”.
[0067] In an embodiment, the spiral spring 24” is configured for selectively allowing the haptic feedback applied to the first end effector portion 22a” to be transferred to the second end effector portion 22b”. For instance, in the first operating mode, the tensile forces due to the stiffness of the spiral spring 24” oppose the vibrations from the first end effector portion 22a” and resist the movement thereof so that the second end effector portion 22b” remains static and does not vibrate, while in the second operating mode, the intensity and / or frequency of the vibrations cause the first and second end effector portions 22a”, 22b” to resonate and vibrate together, without any opposition from the spiral spring 24”. In this regard, the spiral spring 24” defines an adjustable mechanical coupling between the first end effector portion 22a” and the second end effector portion 22b”, the coupling being defined by a predetermined stiffness, damping, and effective mechanical impedance. The first and second end effector portions 22a”, 22b” can further differ in mass and inertial properties, such that vibrational energy generated by the actuator 14” is preferentially confined to the first end effector portion 22a” under certain excitation conditions. As such, the haptic element 10” is configured for operating in a first operating mode in which the haptic vibrations from the actuator 14” are transferred only to the first haptic feedback region (via first end effector portion 22a”) and a second operating mode in which the haptic vibrations from the actuator 14” are transferred to the entire haptic feedback region (via first and second end effector portions 22a”, 22b”, respectively). Stated differently, in the second operating mode, the actuator 14” is configuredto resonate the entire end effector 22” when operating at specific intensity levels and / or frequencies. The first operating mode may be referred to as a localized haptic feedback mode, whereas the second operating mode may be referred to as a systemic haptic feedback mode. In some embodiments, the actuator 14” vibrates at lower intensities in the first operating mode and higher frequencies in the second operating mode.
[0068] The spiral spring 24” is thus configured to selectively and passively decouple the first and second end effector portions 22a”, 22b” from one another. Other connections between the end effector portions 22a”, 22b” configured for passive decoupling of the first and second end effector portions 22a”, 22b” may be contemplated, for instance compliant mechanisms or bistable configurations. In some embodiments, a leaf spring or a non-spiral spring (i.e., a rotationally symmetric spring) is provided in place of the spiral spring 24”.
[0069] In the shown embodiment, the actuator 14” is configured to transmit vibrations to the end effector 22”, for instance upon receiving instructions to do so from the controller 12. The instructions include a targeted haptic feedback area of the haptic feedback region: an isolated portion of the haptic feedback region or a majority of the haptic feedback 20’. Upon receipt of these instructions, the actuator 14” is configured to generate haptic feedback (i.e., vibrations) at a specific frequency and intensity in order to selectively transmit the vibrations, in coordination with the spiral spring 24”, to only the first end effector portion 22a” or to both the first and second end effector portion 22a”, 22b”. The first and / or second end effector portions 22a”, 22b” are thus configured to transmit the haptic feedback to the desired portion (or majority) of the haptic feedback region 20”.
[0070] In the shown case, an annular support member 22c” is received on an underside of the second end effector portion 22b”, although this is optional. A protrusion 22a2” forming a slot 22a1” receiving an end of the actuator 14” is illustratively distinct form the end effector 22”. In other cases, the protrusion 22a2” is integral with one of the first end effector portion 22a” or second end effector portion 22b”.
[0071] It will be appreciated that the haptic elements 10, 10’, 10” shown in Figs. 2A and 3-6, 7-11 and 12-13 are exemplary embodiments of the current technology, and that various other implementations are contemplated. In each of the above-described embodiments, a suspension mechanism, for instance the spiral spring 24, 24” or the active decoupling mechanism is provided for selectively decoupling a portion of the end effector 22, 22’, 22”from the actuator 14, 14’, 14” based on real-time operational parameters to provide localized or systemic haptic feedback. In various embodiments, the above-described selective decoupling is substantially imperceptible to a user of the given device (e.g., seat). In some embodiments, the first operating mode is in the form of discrete, poke-like vibrations, while the second operating mode is in the form of broad, rumble-like vibrations, with both modes achievable using a single actuator 14, 14’, 14”. The actuator 14, 14’, 14” may thus be lightweight and smaller in size, thereby providing a more responsive system that is more easily tunable to resonant frequencies of the system. In addition, haptic element 10, 10’, 10” may be a self-aligning system.
[0072] Various exemplary uses for the haptic elements 10, 10’, 10” are contemplated. For instance, the haptic element 10, 10’, 10” can be used in automobile seats. In an embodiment, the seat includes a massaging function which implements the haptic element 10, 10’, 10” for instance to provide a combination of both localized and general haptic feedback to the user. In another embodiment, a haptic element 10, 10’, 10” in an automotive seat is integrated into the automobile’s advanced driver-assistance systems (ADAS), for instance to provide localized haptic feedback to convey spatial information to the user (e.g., localized feedback on a given side of the seat to signal the detection of another vehicle in the blind spot of the user’s vehicle). Yet other implementations for the above-described haptic elements 10. 10’, 10” are contemplated.
[0073] The above-described haptic elements 10, 10’, 10” are configured for delivering both localized and general haptic effects, for instance to provide wellness and relaxation functionality. For instance, the haptic elements 10, 10’, 10” can be used in automotive and aviation industries, where seating systems are designed to enhance passenger comfort, wellbeing, and engagement during prolonged use.
[0074] Indeed, localized haptic effects focus on precise, targeted stimulation of specific body areas, replicating techniques employed in percussive massage. This is achieved through controlled, rhythmic vibration patterns applied to pressure points, which can alleviate muscle tension and promote blood circulation. For instance, in aviation, the implementation of this functionality in passenger seats may address various health risks associated with prolonged immobility, such as deep vein thrombosis. In automotive contexts, as discussed above, the provision of localized effects in adaptive massage systems can counter driver fatigue during long-distance travel, ensuring alertness and comfort.
[0075] In addition, general haptic effects create a broader sensory experience across larger surface areas. This approach induces a calming or stimulating sensation that envelops the user, fostering relaxation or heightened focus. In aviation, general haptic effects can mitigate the stress of confined cabin environments by promoting a sense of tranquility. Similarly, in automotive contexts, stimulation by way of general haptic effects can enhance the overall sensory environment, particularly in autonomous vehicles, where passenger relaxation becomes a priority.
[0076] The combination of localized and general haptic effects allows for the customization of sensory experiences based on user needs and environmental contexts. For example, while a driver of an automobile might benefit from localized stimulation to reduce tension in their lower back, a passenger in an automobile or airplane might prefer general haptic effects for general relaxation. This dual capability may thus provide to meet a wide range of user preferences and physiological requirements. The haptic elements 10, 10’, 10” described herein are thus configured to provide both precise, localized feedback and wide-area or general feedback.
[0077] Referring now to Fig. 14, another variation of the exemplary haptic element 10‘ of Fig. 7 is shown. As noted above, the haptic element 10’ is configured for selectively providing haptic feedback to some or all of a given haptic feedback region 20’ in a device to be in contact with a user, such as a seat. In particular, the above-described haptic element 10’ includes an active decoupling mechanism (in the form of actuator 14’) to provide active decoupling of the first and second end effector portions 22a’, 22b’. In this shown case, the actuator 14’ includes a shaft 14a’ supporting the first end effector portion 22b’ and a linear actuator or solenoid 14g’ (or other like mechanism) for displacing a connecting element 14h’ towards and away from the first and second end effector portions 22a’, 22b’ to selectively couple and decouple the first and second end effector portions 22a’, 22b’. The shaft 14a’ and the linear actuator or solenoid 14g’ thus effectively form two separate actuators. The connecting element 14h’ is selectively displaceable (illustratively vertically displaceable) by the linear actuator or solenoid 14g’ to mechanically connect the first and second end effector portions 22a’ and 22b’, thereby adjusting the amount of coupling therebetween. In the shown case, the shaft 14a’ is positioned in a first side (illustratively an underside) of the end effector 22’ while the linear actuator or solenoid 14g’ and connecting element 14h’ are positioned on a second side (illustratively a top side) of the end effector 22’. Other configurations are contemplated, for instance all elements of the actuator 14’ (i.e., the shaft 14a’, linear actuator or solenoid 14g’ andconnecting element 14h’) on a same side of the end effector 22’. In embodiments, the connecting element 14h’ is a rubber element selectively movable into contact with the first and second end effector portions 22a’, 22b’, although other connecting elements 14h’ are contemplated. As such, the first operating mode of the haptic element 10’ corresponds to the connecting element 14h’ being spaced apart from (and thus not connecting) the first and second end effector portions 22a’, 22b’, whereas the second operating mode of the haptic element 10’ corresponds to the connecting element 14h’ mechanically connecting the first and second end effector portions 22a’, 22b’. In the first operating mode, the first end effector portion 22a’ is decoupled from the second end effector portion 22a’ and is thus configured to provide haptic feedback to a particular region, whereas in the second operating mode, the first and second end effector portions 22a’, 22b’ are mechanically coupled and thus configured to provide haptic feedback to a greater region. In embodiments, the linear actuator or solenoid 14g’ is configured to displace the connecting element 14h’ between one or more intermediate positions to vary the degree of coupling between the first and second end effector portions 22a’, 22b’, thereby modulating the effective area of haptic feedback transmitted by the haptic element 10’ (i.e., providing intermediate modes between the first and second operating modes). Other configurations are contemplated.
[0078] Now referring to Fig. 15, there is shown a method 100 for controlling a haptic element, such as the haptic elements 10, 10’, 10”. The method 100 may be performed by a controller, such as controller 12. The method 100 starts at step 102.
[0079] At step 104, an indication of a predefined haptic pattern is received by the controller.
[0080] At step 106, a control signal is generated based on the predetermined haptic pattern.
[0081] At step 108, the control signal is provided is provided to at least one actuator coupled to a haptic feedback transmitter, the haptic feedback transmitter configured for transmitting a haptic effect to a user within a haptic feedback region.
[0082] At step 110, the controller determines the nature of the predefined haptic pattern.
[0083] At step 112a, if the predefined haptic pattern is a localized haptic pattern, the haptic feedback transmitter transmits the haptic effect to a localized portion of the haptic feedback region.
[0084] At step 112b, if the predefined haptic pattern is a general haptic pattern, the haptic feedback transmitter transmits the haptic effect to an entire portion of the haptic feedback region.
[0085] The method ends at step 114.
