SYSTEM FOR TRACKING A GOLF BALL AND DISPLAYING AN ENHANCED IMAGE OF THE GOLF BALL
BACKGROUND
[0001] The present invention relates generally to a system for tracking a golf ball and displaying an enhanced image of the golf ball.
[0002] The game of golf is an increasingly popular sport at both amateur and professional levels. Both amateur and professional golfers spend sizeable amounts of time developing the muscle memory and fine motor skills necessary to improve their game. Golfers try to improve their game by analyzing launch and trajectory information while playing golf. Golf balls are difficult to see when flying through the air on a golf course. Consequently, it is difficult to track the trajectory of golf balls and to find golf balls after they have landed. Thus, it would be advantageous to make a system for tracking a golf ball.

DETAILED DESCRIPTION
[0014] A system for tracking a golf ball is disclosed. The system may track the trajectory of a golf ball and display an enhanced image of the golf ball on a display such that the enhanced image is imposed upon a user's real world view. Displaying an enhanced image of the golf ball may help a user view the trajectory of the golf ball and find the golf ball after the golf ball lands. In some embodiments, the system may display an enhanced image of the golf ball on a heads-up display configured to be worn on a person's head. For example, the heads-up display may include a pair of eyeglasses having a lens. By displaying an enhanced image of the golf ball on the lens, the user may view the enhanced image while remaining hands-free. The enhanced image may include at least a portion of the trajectory of the golf ball. Thus, the enhanced image may facilitate tracking the trajectory of the golf ball, which may help the user to compare the golf ball's trajectory with an ideal trajectory. The enhanced image may also help the user see where the golf ball lands, which may help a user find the golf ball. The system may display other information, such as launch and flight information about the ball, on the heads-up display.

For example, in some
embodiments, processor 202 may be configured to communicate with user location sensor 120 to determine the distance between the user and the next pin on the course. Such information would help a user find his yardages during a round of golf.
[0019] Golf ball tracking system 200 may include one or more golf ball sensors. The golf ball sensor may be configured to detect the golf ball. The golf ball sensor may be mounted on or housed within eyeglasses 102. For example, as shown in FIG. 1 , a golf ball sensor 1 10 may be mounted such that golf ball sensor 1 10 is exposed through an opening 1 12 in eyeglasses 102. FIG. 1 shows golf ball sensor 1 10 as being mounted such that it will be positioned above the user's left eye when a user wears eyeglasses 102. In other embodiments, golf ball sensor may be positioned in any suitable position. The location and number of golf ball sensors may be selected based on a number of factors. For example, the location of the golf ball sensor may be
selected based on the positioning of other components and/or the sensitivity of the golf ball sensor.
[0020] In some embodiments, the golf ball sensor may include a reflective sensor capable of detecting the location of a golf ball without any communication components being provided within the golf ball. For example, the golf ball sensor may include radar, LIDAR, optical, and/or sonar sensors.

FIG. 1 shows camera lens 106 as being mounted so that it will be positioned above the user's right eye when a user wears eyeglasses 102. In other embodiments, the camera may be positioned in any other suitable position. The location of the camera may be selected based on a number of factors. For example, the location of the camera may be selected to provide the camera lens in a position close to the user's eye so that the view from the camera is similar to the view from the user's eye.
[0025] In some embodiments, processor 202 may be configured to process information relayed to and from the golf ball sensor and/or the communication component provided with the golf ball. Processor 202 may use this information to determine the location of the golf ball. In some embodiments, the processor may also be configured to control display system 208. As a result, the processor may control the images shown by the display. In some embodiments, processor 202 may be configured to process information relayed to and from user location sensor 120. The processor may use this information to determine the location of the user. In some embodiments, the processor may determine the distance between the user and a landmark, such as the pin or a restroom. In some embodiments, processor 202 may be configured to process information relayed to processor 202 from camera 204. Processor 202 may use this information to display images captured and recorded by the camera to the user. Processor 202 may be configured to display enhanced images to the user.
[0026] In some embodiments, the system may include an interface 1 14 configured to communicate with components of the system. In some
embodiments, the interface may be in communication with golf ball tracking system 200, camera 204, and/or eyeglasses 102 either directly or through processor 202. Interface 1 14 may be in communication with processor 202, golf ball tracking system 200, camera 204, and/or eyeglasses 102 either wirelessly or by wire. For example, FIG. 1 shows wire 1 16 extending through an opening 120 in eyeglasses 102. Wire 1 16 may couple interface 1 14 to processor 202. Interface 1 14 may provide the user with a way to control system 100. In some embodiments, interface 1 14 may have an interface display. Such an interface display may show information about control settings and commands for system 100. In some embodiments, interface 1 14 may have inputs for providing data and control signals to system 100. For example, interface 1 14 may have buttons. In some embodiments, system 100 may include a touch screen that provides both an interface display and an input. In some embodiments, a user may wear eyeglasses 102 and put interface 1 14 in his pocket during use.
[0027] As discussed above, golf ball tracking system 200 may include a golf ball provided with communication components that are configured to communicate with a golf ball sensor. FIGS. 3 and 4 show a golf ball 300 that may be provided with communication components. Golf ball may include any suitable type of golf ball. For example, in some embodiments, golf ball 300 may be a one-piece golf ball. In other embodiments, golf ball 300 may be a multi-piece golf ball, such as a 2-piece or 3-piece golf ball. Golf ball 300 may have an outer surface including dimples 302. Golf ball 300 may be provided with communication components including emitting diodes 304 and a microchip 400. For example, the communication components may include those described in U.S. Patent Number 6,634,959, entitled Golf Ball Locator, issued to Kuesters on October 21 , 2003, the disclosure of which is hereby
incorporated by reference in its entirety, and as described in U.S. Patent Number 5,564,698, entitled Electromagnetic Transmitting Hockey Puck, issued to Honey et al. on October 15, 1996, the disclosure of which is hereby incorporated by reference in its entirety. Emitting diodes 304 may be disposed on the outer surface of golf ball 300. FIG. 4 shows a cross-sectional view of
golf ball 300. As shown in FIG. 4, microchip 400 may be disposed inside golf ball 300. Emitting diodes 304 may be connected to microchip 400 by wires 402. In some embodiments, microchip 400 may be configured to power and control emitting diodes 304. In some embodiments, microchip 400 may be configured to communicate with processor 202. For example, microchip 400 may be configured to communicate with processor 202 via wireless signals. In some embodiments, microchip 400 may include a power source, timing circuits, on/off switches, a pulsing circuit, and/or shock sensors to control the powering of emitting diodes 304. In such embodiments, the shock sensors may be configured to detect movement of golf ball 300. Accordingly, movement of golf ball 300 may trigger the on/off switch to power emitting diodes 304. To conserve power, timing circuits may be configured to control how long emitting diodes 304 are powered. Thus, shock sensors may detect when a golf club strikes golf ball 300, which may trigger the on/off switch to power emitting diodes 304 while golf ball 300 is in flight. After a predetermined amount of time, the timing circuits may trigger the on/off switch to shut off power to emitting diodes 304.
[0028] In embodiments in which golf ball 300 includes emitting diodes 304, golf ball sensor 1 10 may be configured to detect signals from emitting diodes 304. For example, emitting diodes 304 may include infrared emitting diodes and golf ball sensor 1 10 may include an infrared receiver. Golf ball sensor 1 10 may transmit this data to processor 202. Processor 202 may be configured to use this data to determine the location of emitting diodes 304, and thus, the location of golf ball 300. In some embodiments, in place of or in addition to golf ball sensor 1 10, camera 204 may be configured to detect emissions from emitting diodes 304. In some embodiments, in place of or in addition to golf ball sensor 1 10, multiple golf ball sensors may be provided in the location in which the golf ball is to be tracked. For example, multiple golf ball sensors may be provided in various positions on a golf course. In such embodiments, the position of the golf ball sensors may be known and the golf ball sensors may be used to determine the location of the golf ball by detecting emissions from emitting diodes 304.
[0029] FIG. 5 illustrates a user 500 wearing eyeglasses 102 while using a golf club 508 to hit a golf ball 300 off of a tee 504 in a tee box 506. FIG. 6 shows the user's view after he hits golf ball 300. Eyeglasses 102 provide an enhanced image of golf ball 300 imposed upon the user's real world view such that the enhanced image's position matches the position of golf ball 300. In FIG. 6, the user's real world view through lens 104 includes golf ball 300, a tree 514, and a pond 512 disposed within user's line of sight. The enhanced image adds a comet tail 600 to golf ball 300 as golf ball 300 flies through the air toward tree 514 and pond 512. Comet tail 600 may lag behind golf ball 300 such that comet tail 600 stays visible after golf ball 300 lands. Comet tail 600 may represent at least a portion of the trajectory of golf ball 300. In some embodiments, comet tail 600 may represent the entire trajectory of golf ball 300. As a result, user 500 may see the entire trajectory of golf ball 300 at least temporarily after golf ball 300 lands.
[0030] FIG. 8 shows a method 800 of displaying an enhanced image of the golf ball imposed upon the golfer's real world view according to an embodiment. The steps of method 800 may be performed in any order. Step 802 may include capturing and recording images from the user's viewpoint. Step 804 may include transmitting the recorded images to processor 202.
Camera 204 may perform steps 802 and 804. Step 806 may include tracking the location of golf ball 300. Golf ball tracking system 200 and/or processor 202 may perform step 804. For example, in the embodiment discussed above with reference to FIGS. 3 and 4, hitting golf ball 300 may trigger shock sensors. As a result, on/off switches may cause microchip 400 to power emitting diodes 304, which may cause emitting diodes 304 to pulse. Golf ball sensor 1 10 may detect the pulses and transmit data to processor 202. Processor 202 may use the transmitted data to determine the location of emitting diodes 304, and thus, the location of golf ball 300.
[0031] Step 808 may include displaying an enhanced image of golf ball 300 upon the user's real world view. In some embodiments, processor 202 may use the location of golf ball 300 and the images recorded by camera 204 to make display system 208 display an enhanced image of golf ball 300 to user
500. The enhanced image may be displayed such that the enhanced image overlays the user's real world view. In some embodiments, the enhanced image may be transparent. In some embodiments, the enhanced image may be stereoscopic. In some embodiments, the enhanced image may be bigger and/or brighter than the recorded image. For example, the enhanced image may appear to be glowing. The enhanced image may be selected to make golf ball 300 and the trajectory of golf ball 300 stand out more to the user while allowing user to still see a real world view. As shown in FIG. 6, the enhanced image may include comet tail 600 trailing behind golf ball 300. Comet tail 600 may show the trajectory of golf ball 300 such that user 500 can compare the trajectory of golf ball 300 to an ideal trajectory. In some embodiments, display system 208 may display an ideal trajectory such that the trajectory of golf ball 300 may be compared with the ideal trajectory.
[0032] In some embodiments, processor 202 may use the location of golf ball 300 at various times to determine launch information and/or flight information about golf ball 300. In some embodiments, to determine launch information and/or flight information about golf ball 300, system 100 may use methods and components described in U.S. Patent Application Publication 2007/0021226, entitled Method of and Apparatus for Tracking Objects in Flight Such as Golf Balls and the Like, applied for by Tyroler and published on January 25, 2007, the disclosure of which is hereby incorporated by reference in its entirety. In some embodiments, to determine launch information and/or flight information about golf ball 300, system 100 may use methods and components described in U.S. Patent Application Publication 2005/0233815, entitled Method of Determining a Flight Trajectory and Extracting Flight Data for a Trackable Golf Ball, applied for by McCreary et al. and published on October 20, 2005, the disclosure of which is hereby incorporated by reference in its entirety. In some embodiments, to determine launch information and/or flight information about golf ball 300, system 100 may use methods and components described in U.S. Patent Application Publication 2010/0151955, entitled Global Positioning System Use for Golf Ball Tracking, applied for by Holden and published on June 17, 2010, the disclosure of which is hereby incorporated by
reference in its entirety. To determine launch information and/or flight information about golf ball 300, system 100 may use methods and components described in U.S. Patent Application Publication 2008/0254916, entitled Method of Providing Golf Contents in Mobile Terminal, applied for by Kim et al. and published on October 16, 2008, the disclosure of which is hereby incorporated by reference in its entirety. FIG. 7 shows how information may be displayed to the user. For example, launch information, such as initial velocity, and the distance to the pin may be displayed on lens 104. In another example, lens 104 may display the ball spin rate and/or launch angle. By displaying information to user 500 on eyeglasses 102, user 500 may reference this information without having to pull out a device or without having do anything other than look in front of his eye. Accordingly, the user may quickly and easily reference information without having to distract from other activities.
[0033] In some embodiments, system 100 may include a separate launch monitor configured to monitor and record data related to the golf ball, golf club, and/or golfer. For example, system 100 may include the launch monitor described in U.S. Patent Application Serial Number 13/307,789, entitled Method and Apparatus for Determining an Angle of Attack from Multiple Ball Hitting, applied for by Ishii et al. and filed on November 30, 201 1 , the disclosure of which is hereby incorporated by reference in its entirety. The separate launch monitor may be in communication with processor 202.
[0034] User tracking system 206 may determine the location of user 500. For example, in embodiments in which global positioning system receiver 120 is included in eyeglasses 102, global positioning system receiver 120 may determine the location of user and transmit the location of the user to processor 202. Processor 202 may be configured to know the locations of various landmarks on a golf course. Processor 202 may be configured to determine the distance between the location of the user and the various landmarks on the golf course. For example, processor 202 may be configured to determine the distance between user 500 and the next pin on the golf course. Processor 202 may be configured to display this distance to user 500, as shown in FIG. 7. In some embodiments, the user may be a golfer wearing eyeglasses 102. In
some embodiments, the user may be a caddy wearing eyeglasses 102 and watching a golfer. The caddy may use the system to help the golfer choose clubs, adjust his swing, and find golf balls. In some embodiments, the user may be a spectator wearing the eyeglasses and watching a golfer.
[0035] In some embodiments, system 100 may display an image of golf ball 300 and/or an image of user 500 on a representation of the golf course. Display system 208 may display these images to user 500 on eyeglasses 102 to help user 500 navigate and/or locate golf ball 300. To display the images, system 100 may use the methods and components described in U.S. Patent Application Publication 2007/0021226, U.S. Patent Application Publication 2005/0233815, U.S. Patent Application Publication 2010/0151955, and/or U.S. Patent Application Publication 2008/0254916.
[0036] While various embodiments of the invention have been described, the description is intended to be exemplary, rather than limiting and it will be apparent to those of ordinary skill in the art that many more
embodiments and implementations are possible that are within the scope of the invention. Accordingly, the invention is not to be restricted except in light of the attached claims and their equivalents. Also, various modifications and changes may be made within the scope of the attached claims.
