[0014] FIG. 1 is a block diagram illustrating an electronic device according to an embodiment.

[0015] The electronic device 100 may include a wireless communication unit 110, a sensing unit 120, a user input unit 130, an interface unit 140, an output unit 150, a memory 160, a control unit 170, and a power supply unit 180. The components illustrated in FIG. 1 are not essential for implementing the electronic device 100, and the electronic device 100 described herein may have more or fewer components than those listed above.

[0016] More specifically, among the components, the wireless communication unit 110 may include one or more modules that enable wireless communication between the electronic device 100 and a wireless communication system, between the electronic device 100 and other wireless communication-enabled devices, or between the electronic device 100 and an external server.

[0017] The wireless communication unit 110 may include a wireless internet module 111 and a short-range communication module 112 .

[0018] The wireless internet module 111 refers to a module for wireless internet connection and may be built into the electronic device 100. The wireless internet module 111 is configured to transmit and receive wireless signals over a communication network using wireless internet technologies. Examples of wireless internet technologies include wireless LAN (WLAN), wireless fidelity (Wi-Fi), wireless fidelity (Wi-Fi) Direct, digital living network alliance (DLNA), wireless broadband (WiBro), world interoperability for microwave access (WiMAX), high speed downlink packet access (HSDPA), high speed uplink packet access (HSUPA), long term evolution (LTE), and long term evolution-advanced (LTE-A). The wireless internet module 111 transmits and receives data according to at least one of the wireless internet technologies, including internet technologies not listed above.

[0019] The short-range communication module 112 is for short-range communication and may support short-range communication using at least one of Bluetooth, RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB (Ultra Wideband), ZigBee, NFC (Near Field Communication), Wi-Fi (Wireless Fidelity), Wi-Fi Direct, and Wireless Universal Serial Bus (Wireless USB) technologies. The short-range communication module 112 may support wireless communication between the electronic device 100 and a wireless communication system, between the electronic device 100 and a wireless communication-enabled device, or between the electronic device 100 and a network in which an external server is located, through a wireless area network. The short-range wireless communication network may be a wireless personal area network.

[0020] Here, the wireless communication enabled device may be a mobile terminal (e.g., a smartphone, a tablet PC, a notebook, etc.) capable of exchanging data with (or interoperating with) the electronic device 100 according to the present invention. The short-range communication module 112 may detect (or recognize) a wireless communication enabled device capable of communicating with the electronic device 100 in the vicinity of the electronic device 100. Furthermore, if the detected wireless communication enabled device is a device authenticated to communicate with the electronic device 100 according to an embodiment, the control unit 170 may transmit at least a portion of data processed by the electronic device 100 to the wireless communication enabled device via the short-range communication module 112. Thus, a user of the wireless communication enabled device may use the data processed by the electronic device 100 via the wireless communication enabled device.

[0021] The sensing unit 120 may include one or more sensors for sensing at least one of information about the environment surrounding the electronic device 100 and information within the electronic device 100. For example, the sensing unit 120 may include a position acquisition sensor 121 and an inertial sensor 122, and may additionally include at least one of a battery gauge, an infrared sensor, an inclination sensor, a brightness sensor, an altitude sensor, an olfactory sensor, a temperature sensor, a depth sensor, a pressure sensor, a banding sensor, an audio sensor, a video sensor, a grip sensor, and a touch sensor. Meanwhile, the electronic device 100 disclosed herein may utilize information sensed by at least two of these sensors in combination.

[0022] The sensing unit 120 may collectively refer to the various sensing means described above. The sensing unit 120 may sense various user inputs and the user's environment and transmit the sensing results so that the control unit 170 can perform an operation accordingly. The sensors described above may be included in the electronic device 100 as separate elements or may be integrated into at least one element.

[0023] First, the position acquisition sensor 121 is a sensor for acquiring the position of the electronic device 100, and a representative example thereof is a GPS (Global Positioning System) sensor. A GPS sensor calculates distance information and accurate time information from three or more satellites, and then applies trigonometry to the calculated information to accurately calculate three-dimensional current position information according to latitude, longitude, and altitude. Currently, a widely used method is to calculate position and time information using three satellites and then correct errors in the calculated position and time information using another satellite. In addition, a GPS sensor can calculate speed information by continuously calculating the current position in real time. The position acquisition sensor 121 can provide position information according to time.

[0024] The inertial sensor 122 is a sensor for detecting the inertial force of the movement of the electronic device 100 and acquiring various information such as the acceleration, speed, direction, and distance of the electronic device 100 over time. The inertial sensor 122 acquires information about changes occurring in the electronic device 100 in order to analyze a swing occurring when a user uses a golf club. When a user swings a golf club, the acceleration and angular velocity of the golf club change, and similar changes also occur in the electronic device 100.

[0025] The inertial sensor 122 may include an acceleration sensor and a gyro sensor. For example, the inertial sensor 122 may be a six-axis inertial measurement unit (IMU) that combines a three-axis (x, y, z) acceleration sensor and a three-axis gyro sensor.

[0026] The acceleration sensor can acquire the degree of tilt of the electronic device 100. For example, the acceleration sensor can acquire the degree of tilt by calculating the tilt using the angle of rotation in the up and down direction from a preset reference direction acquired by the gyro sensor. The acceleration sensor can measure, for example, a maximum of 16 g and have a sampling rate of 500 Hz.

[0027] The gyro sensor can acquire the angular velocity of the angle that the electronic device 100 rotates per time. For example, the gyro sensor can have a maximum of 2000 dps (degrees per second) and a sampling rate of 50 Hz.

[0028] The inertial sensor 122 will be described with reference to Fig. 2. Fig. 2 is an exemplary diagram showing axes of an inertial sensor according to an embodiment.

[0029] 2(a) is a diagram visually illustrating the axes of the inertial sensor 122. As shown in FIG. 2(a), a direction perpendicular to the display unit 151 of the electronic device 100 is represented as the z-axis, a direction perpendicular to the z-axis and parallel to the display unit 151 is represented as the x-axis, and a direction perpendicular to both the x-axis and the z-axis is represented as the y-axis.

[0030] Here, the acceleration sensor can measure the acceleration in the x-axis direction (ax), the acceleration in the y-axis direction (ay), and the acceleration in the z-axis direction (az). At this time, the magnitude of the acceleration sensor value (an) is the magnitude of the acceleration vector in the three axes, i.e. The file is TIFF0007752448000001.tif11156.

[0031] The gyro sensor can measure the angular velocity (gx) when rotating around the x-axis, the angular velocity (gy) when rotating around the y-axis, and the angular velocity (gz) when rotating around the z-axis. At this time, the magnitude of the gyro sensor value (gn) is the magnitude of the angular velocity vector in the three axial directions, i.e., The file is TIFF0007752448000002.tif11156.

[0032] 2(b) is a diagram visually illustrating the axes of the inertial sensor 122 when a user wears the electronic device 100. Since the electronic device 100 is carried by the user, the axial direction of the electronic device 100 is not fixed but changes depending on the movement of the user.

[0033] The inertial sensor 122 can acquire motion data. The motion data can include acceleration information including acceleration on three axes (ax, ay, az) and the magnitude of the acceleration (an), and angular velocity information including rotational angular velocities about three axes (gx, gy, gz) and the magnitude of the angular velocity (gn).

[0034] Next, the user input unit 130 receives information input from a user. When information is input through the user input unit 130, the control unit 170 can control the operation of the electronic device 100 in accordance with the input information. The user input unit 130 can include a mechanical input means (or mechanical keys, for example, buttons located on the front, rear, or side of the electronic device 100, a bezel or crown of the electronic device 100, a dome switch, a jog wheel, a jog switch, etc.) and a touch input means. For example, the touch input means can be virtual keys, soft keys, or visual keys displayed on a touch screen through software processing, or can be touch keys located outside the touch screen. Meanwhile, the virtual keys or visual keys may be displayed on the touch screen in various forms, for example, graphics, text, icons, videos, or a combination thereof.

[0035] The interface unit 140 serves as a passageway for various external devices connected to the electronic device 100. The interface unit 140 may include at least one of an external charger port, a wired / wireless data port, and a memory card port 160. When an external device is connected to the interface unit 140, the electronic device 100 may perform appropriate control related to the connected external device.

[0036] The output unit 150 generates an output related to the visual, auditory, or tactile senses, and may include a display unit 151, an audio output unit 152, a vibration output unit 153, and the like.

[0037] The display unit 151 displays (outputs) information processed by the electronic device 100. For example, the display unit 151 may display execution screen information of an application program run on the electronic device 100, or UI (User Interface) or GUI (Graphical User Interface) information corresponding to the execution screen information. Two or more such display units 151 may be present depending on the implementation of the electronic device 100.

[0038] The display unit 151 may include at least one of a liquid crystal display (LCD), a thin film transistor liquid crystal display (TFTLCD), an organic light-emitting diode (OLED), and an e-ink display.

[0039] The audio output unit 152 can output audio data stored in the memory 160 as sound, and is implemented in the form of a loud speaker that outputs various alarm sounds and multimedia playback sounds.

[0040] The vibration output unit 153 generates various haptic effects that can be felt by the user. The strength and pattern of the vibration generated by the vibration output unit 153 can be controlled by the user's selection or the setting of the control unit 170. For example, the vibration output unit 153 can output a combination of different vibrations or output them sequentially.

[0041] Additionally, the output unit 150 may further include an optical output unit that outputs a signal indicating the occurrence of an event using light from a light source.

[0042] The memory 160 also stores data supporting various functions of the electronic device 100 (e.g., the data may include, but is not limited to, course map information (e.g., location, elevation, slope, undulation, material, characteristics, width, etc.) for the tee boxes, fairways, hazards, bunkers, rough, greens, holes, etc.) of a golf course. The memory 160 may also store firmware and application programs operated by the electronic device 100, as well as data and instructions for the operation of the electronic device 100. At least some of these application programs may be present in the electronic device 100 at the time of shipment for the basic functions of the electronic device 100. At least some of these application programs may be downloaded from an external server via wireless communication. Meanwhile, the application programs may be stored in the memory 160, installed on the electronic device 100, and driven by the control unit 170 to perform the operations (or functions) of the electronic device 100.

[0043] In addition to operations related to the application programs, the controller 170 generally controls the overall operation of the electronic device 100. The controller 170 processes signals, data, information, etc. input or output via the above-mentioned components, and runs application programs stored in the memory 160 to provide or process appropriate information or functions to the user.

[0044] 1 to operate an application program stored in the memory 160. Furthermore, the controller 170 may operate at least two or more components included in the electronic device 100 in combination with each other to operate the application program.

[0045] The power supply unit 180 receives an external power source or an internal power source under the control of the control unit 170 and supplies power to each component included in the electronic device 100. The power supply unit 180 includes a battery, which may be an internal battery or a replaceable battery.

[0046] At least some of the components may cooperate with each other to realize the operation, control, or control method of the electronic device 100 according to various embodiments described below. In addition, the operation, control, or control method of the electronic device 100 may be realized on the electronic device 100 by running at least one application program stored in the memory 160.

[0047] The electronic device 100 may be applied to various structures such as a watch type, a clip type, a glasses type, or a slide type, a swing type, a swivel type in which two or more bodies are coupled to be able to move relative to one another, etc. Although the description relates to a specific type of electronic device 100, the description of the specific type of electronic device 100 may be generally applicable to other types of electronic devices 100.

[0048] A method for controlling the electronic device 100 according to an embodiment will be described with reference to Fig. 3. Fig. 3 is a flowchart of the method for controlling the electronic device according to an embodiment.

[0049] First, the position acquisition sensor 121 acquires the current position (S310).

[0050] The location acquisition sensor 121 can acquire coordinates of the current location of the electronic device 100. According to an embodiment of the present invention, since the user mainly wears the electronic device 100 on the wrist, the current location of the electronic device 100 is the same as the current location of the user. The current location of the electronic device 100 can be periodically acquired and updated according to user input.

[0051] The control unit 170 determines the shot mode (S320).

[0052] Specifically, the control unit 170 can determine a shot mode using the coordinates of the current position and the corresponding course map information. For example, the control unit 170 can read the course map information corresponding to the coordinates of the current position from the memory 160. The control unit 170 can combine the read course map information with the current position information obtained from the position acquisition sensor 121 to determine whether the electronic device 100 is currently near the tee box, on the fairway, outside the green, or inside the green.

[0053] Based on this, the control unit 170 may determine the mode as full swing mode when the current position of the electronic device 100 is on the tee box or on the fairway. Also, the control unit 170 may determine the mode as approach mode when the current position of the electronic device 100 is within a preset range from the green. For example, the control unit 170 may determine the mode as approach mode when the current position of the electronic device 100 is within 50 m from the green. The control unit 170 may determine the mode as putting mode when the current position of the electronic device 100 is on the green.

[0054] Of course, the user can select a shot mode different from the shot mode determined by the control unit 170 via the user input unit 130. Then, the control unit 170 can perform the next step based on the shot mode selected by the user.

[0055] The control unit 170 acquires the user's motion data (S330).

[0056] The control unit 170 may acquire user motion data from the inertial sensor 122. Here, the user motion data may be a motion input including a wrist-raising motion and / or a wrist-rotating motion of the user. For example, when the user lifts the electronic device 100 from a dropped pose to an ascending pose, the user raises the wrist and / or rotates the wrist. Then, the control unit 170 determines the wrist-raising motion and / or the wrist-rotating motion based on the motion input.

[0057] Then, the control unit 170 determines whether the user's motion corresponds to a valid swing (S340).

[0058] Generally, during a golf game, most players take several practice swings rather than hitting a golf ball in one go. Therefore, in order to calculate an accurate golf score, it is necessary to distinguish between practice swings and valid swings that actually hit a golf ball. To this end, the control unit 170 analyzes acceleration and angular velocity information from the motion data received from the inertial sensor 122 to determine whether a valid swing condition is met, thereby distinguishing between practice swings and valid swings. The control unit 170 can determine whether an impact has been made on the golf ball using the maximum magnitude value of the acceleration information.

[0059] A golf swing consists of the address (the position where you position your feet and hit the club on the ground before hitting the ball), the backswing (the action of pulling the golf club back after addressing as a preparation for applying force), the downswing (the action of swinging down to hit the golf ball after the backswing), and the follow-through swing (the action of pushing the golf ball forward after hitting it).

[0060] That is, in one swing, the head of the golf club reaches the top of the backswing after the address point by backswinging, and then reaches the impact point by downswinging from the top of the backswing. In other words, the time taken from the address point to the top of the backswing is the backswing period, and the time taken from the top of the backswing to the impact point is the downswing period. The backswing period and the downswing period together can be called the shot tempo.

[0061] Specifically, the control unit 170 can first calculate swing singular points from the motion data, where the swing singular points are the address point, the top point of the backswing, and the impact point.

[0062] During address, the user stops the golf club near the golf ball for a certain period of time. That is, during address, the speed / angle of the golf club is maintained or the change amount is maintained below a specific threshold. Therefore, the control unit 170 can determine the point where the speed is minimum before the backswing occurs as the address point. That is, the point where the speed of the club head is minimum before the backswing period begins can be the address point.

[0063] In addition, the control unit 170 may determine the point where the velocity is minimum after the backswing occurs as the backswing top point. That is, the point where the backswing period ends and the downswing period begins may be the backswing top point.

[0064] The method for determining the impact point differs depending on the type of shot mode.

[0065] In the full swing mode and the approach mode, the control unit 170 may determine the point where the angular velocity (gy) of the gyro sensor has the minimum value as the impact point.

[0066] In the putting mode, the control unit 170 can determine the point where the gradient of the acceleration (az) of the acceleration sensor is maximum as the impact point. In other words, the control unit 170 can determine the point where the acceleration change amount between any time (t) and the time (t-1) immediately before that as the impact point.

[0067] On the other hand, the magnitude of the impact generated when swinging may be the same as the magnitude (an) of the acceleration sensor. For example, the magnitude of the impact will have a maximum value when the golf club head hits the ball at the impact point.

[0068] Since the type of swing performed varies depending on the shot mode, the valid swing satisfaction condition may vary depending on the mode. The control unit 170 may determine whether the valid swing condition is satisfied based on the period between swing singular points.

[0069] In the full swing mode, the control unit 170 determines that the valid swing conditions are met if i) the backswing period is equal to or longer than a predetermined first reference time (T1), ii) the downswing period is equal to or longer than a predetermined second reference time (T2), and iii) the maximum amount of impact is equal to or longer than a first threshold value.

[0070] In the approach mode, the control unit 170 determines that the valid swing conditions are met if i) the backswing period is equal to or longer than a preset third reference time (T3), ii) the downswing period is equal to or longer than a preset fourth reference time (T4), and iii) the maximum amount of impact is equal to or greater than a second threshold value.

[0071] In the putting mode, the control unit 170 determines that the valid swing conditions are met if i) the backswing period is equal to or longer than a preset fifth reference time (T5), ii) the downswing period is shorter than a preset sixth reference time (T6), and iii) the maximum value of the angular velocity (gy) of the gyro sensor is less than a third threshold value.

[0072] Generally, in the full swing mode on the tee box or fairway, the backswing period is long and the impact is large, while in the putting mode on the green, the backswing period is short and the impact is small, as the golf ball is intended to be put into the hole cup.

[0073] Based on this, when comparing the magnitudes of preset reference times, the order is first reference time (T1) > third reference time (T3) > fifth reference time (T5), or it may be second reference time (T2) > fourth reference time (T4) > sixth reference time (T6). Also, the order may be first threshold > second threshold > third threshold.

[0074] However, if a number of valid swings are made within a predetermined time in the full swing mode and the approach mode, the control unit 170 may determine that a swing previously determined as a valid swing is no longer a valid swing. For example, if the control unit 170 determines that the acquired motion data is a valid swing, it may count the number of shots. However, if further motion data is acquired within a predetermined time, it may cancel the number of shots counted for the first hit.

[0075] Even if a swing is considered valid, the control unit 170 can determine that it is not a valid swing based on the user's input via the user input unit 130. Therefore, the control unit 170 can cancel the counted number of shots. Furthermore, even if a swing is not valid, the control unit 170 can determine that it is a valid swing based on the user's input via the user input unit 130 and count the number of shots.

[0076] If the control unit 170 determines that the user's motion corresponds to a valid swing, it can display a screen corresponding to the valid swing on the display unit 151 (S350). If the control unit 170 determines that the user's motion does not correspond to a valid swing, it can perform step S310 again.

[0077] In addition to the course map image, the control unit 170 may also display, but is not limited to, a screen preset by the user, such as a user interface including the current time, a user interface showing the remaining distance from the current position to the hole, and a user interface showing the difference in altitude between the current position and the hole, etc. These images may be constantly displayed on the display unit 151 after the golf game is started.

[0078] When a valid swing is made in the full swing mode / approach mode, the control unit 170 may increase the cumulative number of strokes for the shot and display the cumulative number of strokes on the display unit 151. In addition, when a valid swing is made in the putting mode, the control unit 170 may increase the number of strokes for the putt and display the cumulative number of putts on the display unit 151.

[0079] In this regard, reference will be made to Figure 4. Figures 4 and 5 are diagrams showing screens displayed on the display unit of an electronic device.

[0080] 4, the display unit 151 may display a shot tempo screen 4001. The shot tempo screen 4001 may include a shot tempo 4003, a backswing period 4005, and a downswing period 4007. The backswing period is 2.0 and is displayed in gray, and the downswing period is 0.6 and is displayed in black. The backswing period 4005 and the downswing period 4007 may be displayed in different colors to make them easier to distinguish.

[0081] The user can check the shot tempo of the swing he or she performed and adjust the speed of the swing. When action data is acquired, the shot tempo screen 4001 can be displayed on the display unit 151 even if the swing is not determined to be valid.

[0082] The shot tempo screen 4001 may also include a stroke information display section including a shot information display section 4009 and a putt information display section 4013, a shot stroke indicator 4011, and a putt stroke indicator 4015. This will be described in more detail with reference to FIG.

[0083] The green strategy screen 4002 allows the user to grasp the green and its surroundings in advance by displaying the overall shape and length of the green 4017, the remaining distance to the safe area behind the green 4018, undulations, and the pin position 4019. The undulations can be expressed by color, contour lines, etc.

[0084] 5, the green strategy screen 4002 may include a stroke information display section. The stroke information display section, i.e., the shot information display section 4009 and the putt information display section 4013, may be located along the periphery of the display section 151. For example, the shot information display section 4009 may be located on the edge of the display section 151.

[0085] The shot number indicator 4011 is located below the shot information display section 4009 and can indicate the number of shots. The putt number indicator 4015 is located below the putt information display section 4013 and can indicate the number of putts. The shot number indicator 4011 and the putt number indicator 4015 can be displayed in different colors to make them easier to distinguish.

[0086] 4 and 5, the shot information display section 4009 may have spaces for positioning shot number indicators 4011 from 0 to 6, and the putt information display section 4013 may have spaces for positioning putt number indicators 4015 from 0 to 4. However, the present invention is not limited to this, and the shot information display section 4009 and the putt information display section 4013 may have different numbers of spaces.

[0087] For example, the spaces in which the shot number indicator 4011 can be located may be arranged so that the number of strokes of the accumulated shots increases clockwise. As shown in FIGS. 4 and 5 , the shot information display section 4009 starts at the 12 o'clock position and the number of strokes of the accumulated shots increases clockwise to the 6 o'clock position. The putt information display section 4013 may be arranged so that the number of strokes of the accumulated shots increases clockwise from the position next to the position where the shot information display section 4009 ends. Similarly, the spaces in which the putt number indicator 4015 can be located may be arranged so that the number of strokes of the accumulated putts increases clockwise. As shown in FIGS. 4 and 5 , the putt information display section 4013 starts at the 7 o'clock position and the number of strokes of the accumulated shots increases clockwise to the 11 o'clock position. The positions of the shot information display section 4009 and the putt information display section 4013 and the arrangement of the spaces in which each indicator can be located are not limited thereto and may have various positions and arrangements.

[0088] 5 shows the case where one shot has been taken. For example, if the number of strokes for the shot is 0, a shot stroke number indicator 4011 may be located below the SHOT space in the shot information display section 4009, and if the number of strokes for the putt is 0, a putt stroke number indicator 4015 may be located below the PUTT space in the putt information display section 4013.

[0089] Thereafter, if the control unit 170 determines that the user's action corresponds to a valid swing in the full swing mode / approach mode, it can increase the cumulative number of shots and display the shot number indicator 4011 on the display unit 151 so that it is positioned below the shot information display unit 4009 indicating 1.

[0090] If the number of strokes for a shot exceeds the number of spaces shown in the shot information display section 4009 on the display unit 151, the number of strokes for the shot can be displayed using multiple shot number indicators 4011. For example, if the number of strokes for a shot is 7, the control unit 170 can display the number of strokes for the shot by displaying two shot number indicators 4011 below the shot information display sections 4009 showing 1 and 6, respectively. The same is true for the putt information display section 4013; if the number of strokes for a putt exceeds the number of spaces shown in the putt information display section 4009 on the display unit 151, the number of strokes for the putt can be displayed using multiple putt number indicators 4015.

[0091] The green capture screen 4002 may be output on the display unit 151 for a certain period of time. The time for which the green capture screen 4002 is output may vary depending on the shot mode. This is because the time it takes for the ball to reach its destination may vary depending on the shot mode. For example, in the full swing mode, the green capture screen 4002 is output on the display unit 151 for 30 seconds. In the approach mode, the green capture screen 4002 is output on the display unit 151 for 10 seconds. Finally, in the putting mode, the green capture screen 4002 is output on the display unit 151 for 5 seconds.

[0092] Since the number of shots and putts are initialized and counted again from 0 each time a new hole begins, the shot number indicator 4011 can be located at the bottom of the SHOT space in the shot information display section 4009, and the putt number indicator 4015 can be located at the bottom of the PUTT space in the putt information display section 4013.

[0093] Additionally, the control unit 170 can display not only the shot tempo screen 4001 and the green strategy screen 4002, but also a shot information display section 4009 and a putt information display section 4013 along with other screens on the display unit 151. Of course, the control unit 170 can also display a stroke count information display screen on the display unit 151, including information regarding the number of shots and putts, the shot information display section 4009, the putt information display section 4013, a shot stroke count indicator 4011, and a putt stroke count indicator 4015. In other words, the user can know the number of shots and putts at any time.

[0094] After the screen corresponding to the valid swing is displayed, the current position of the electronic device 100 can be periodically acquired, so that the control unit 170 can start again from step S310.

[0095] According to at least one of the embodiments of the present disclosure, the number of shots and putts made can be easily checked, and score-related information can be checked with simple operations, which has the advantage that the user can conveniently check information appropriate to the user's situation.
