Hockey is a high-intensity sport that involves constant movement, which contributes to cardiovascular fitness. The fast-paced nature of the game helps to improve heart health and endurance. In addition to the cardiovascular benefits, playing hockey develops strength in the lower body for skating and the upper body for stick handling and shooting. Regular play helps develop muscle strength and overall body conditioning. Another benefit of hockey includes coordination and balance. Skating and maneuvering on the ice or field demand a high level of coordination and balance. Moreover, the sport involves a combination of aerobic and anaerobic activities, promoting overall fitness. For example, short bursts of intense activity during sprints and gameplay contribute to anaerobic conditioning. Another benefit provided by hockey play is flexibility. The constant movement and varied actions in hockey help improve flexibility, especially in the hips, knees, and ankles. Yet another benefit of playing hockey includes improved reflexes. Hockey requires quick decision-making and rapid responses to the movements of the puck or ball and other players. Thus, hockey helps enhance reflexes and hand-eye coordination.

[0003] In addition to the aforementioned physical benefits, the sport of hockey also provides multiple social benefits. Hockey is a team sport that emphasizes the importance of working together towards a common objective. Players learn to communicate, coordinate, and support each other on and off the ice or field.
These factors contribute to the development of teamwork skills. Moreover, participating in hockey can also serve to develop leadership skills. Players often Date Recue/Date Received 2023-12-08 take on leadership roles, such as team captain or alternate captain. Players learn to respect opponents, referees, and teammates, contributing to a positive sporting culture. Furthermore, the sport of hockey can help develop communication skills. Effective communication is essential on the hockey rink.

Players need to convey strategies, call for passes, and coordinate plays.
Players learn to respect opponents, referees, and teammates, contributing to a positive sporting culture. Moreover, being part of a hockey team can help develop discipline and time management skills. Regular practice schedules and the commitment to team activities teach players discipline and time management skills. For young players, balancing sports with other responsibilities can develop into a valuable life skill. Thus, playing hockey offers a holistic approach to physical fitness while promoting essential social skills that can positively impact various aspects of life.

In one or more embodiments, electronic display 201 comprises a touchscreen, enabling user interface functionality. In one or more embodiments, the touchscreen includes a capacitive touchscreen, resistive touchscreen, infrared (IR) touchscreen, or other suitable touchscreen type. In one or more embodiments, the electronic display comprises a liquid crystal display (LCD), organic light-emitting diode (OLED) display, AMOLED (Active-Matrix Organic Light-Emitting Diode), or other suitable display type.

[0038] Augmented Reality (AR) is a technology that overlays digital information, such as images, videos, or 3D models, onto the real-world environment in real-time. Disclosed embodiments provide real-time interaction by superimposing digital information onto the user's view of the real world, which includes a hockey practice area, hockey stick, and/or hockey workpiece. Disclosed embodiments track the hockey workpiece to enable the hockey workpiece to interact with one or more augmented reality elements, such as targets, virtual lines, virtual goal nets, and so on. In embodiments, a target defines an area in which the hockey workpiece (e.g., puck or ball) is intended to pass through as part of a hockey exercise or drill. Disclosed embodiments utilize object tracking for tracking a hockey workpiece with computer vision techniques and/or machine learning.
This can include a series of steps to detect and follow the position of a hockey workpiece (e.g., puck or ball) across consecutive frames in a video or image sequence. The steps can include detecting the hockey workpiece in the initial frame of the video. The detection can be done using object detection algorithms, Date Recue/Date Received 2023-12-08 which identify regions of interest (ROI) in the image that likely contain the hockey workpiece. One or more embodiments may utilize an object detection algorithm including, but not limited to, YOLO (You Only Look Once), SSD (Single Shot Multibox Detector), and Faster R-CNN (Region-based Convolutional Neural Network). The steps may further include a feature extraction process. Once the hockey workpiece is detected, features such as color, texture, or shape are extracted from the detected region. These features help uniquely identify the hockey workpiece in subsequent frames. One or more embodiments may further utilize a tracking algorithm. The tracking algorithm may be initialized by using the detected features to create a "track" for the hockey workpiece. The initialization may involve creating a bounding box around the hockey workpiece and/or extracting key points. In one or more embodiments, a motion prediction process is used to enable more accurate tracking. The motion prediction process can include estimating the direction and speed of the ball based on its previous positions. In one or more embodiments, Kalman filters and/or Particle Filters are used in the motion prediction process. In one or more embodiments, a computer vision framework, such as OpenCV is used for providing tools and functions for implementation of hockey workpiece tracking using various algorithms.

[0039] The electronic computing device 200 can include an image capturing device (camera) that is configured to acquire still images and/or video. In embodiments, the image capturing device can be configured to obtain images from a downward viewpoint of an area in front of a user. As shown in FIG. 2, this includes the hockey stick 242, and hockey workpiece 244 of the user. For example, referring again to FIG. 1, the hockey stick 104 of FIG. 1, and hockey workpiece 106 of FIG. 1 can be represented by hockey stick 242 and hockey workpiece 244 of FIG. 2. One or more augmented reality targets may be synthesized and rendered on the display 201. As shown in FIG. 2, four augmented reality targets are shown, indicated as 204, 206, 208, and 210. In one exemplary use of disclosed embodiments, a user manipulates the hockey workpiece with his/her hockey stick to move the hockey workpiece such that the Date Recue/Date Received 2023-12-08 hockey workpiece overlaps with one or more targets during the course of travel of the hockey workpiece. In embodiments, a performance metric, such as a score, is computed and rendered on the display 201, such as score 234, indicating a current score of 6. In one or more embodiments, an objective of a hockey drill is to "clear" all the targets as quickly as possible, by manipulating the hockey workpiece (e.g., puck, ball, etc.) such that the rendering of the hockey workpiece on display 201 overlaps with the rendering of an augmented reality target. In one or more embodiments, when the hockey workpiece overlaps with the augmented reality target, the augmented reality target is removed from the screen, and the score is incremented accordingly. Additionally, in one or more embodiments, an elapsed time for clearing the targets is rendered as shown at reference 232. In one or more embodiments, a bonus is added to the score when all targets are cleared within a predetermined time interval. As an example, a bonus of 10 points may be added to the final score when all augmented reality targets are cleared within 30 seconds. As a user continues to practice using disclosed embodiments, his/her stick-handling techniques can improve. The electronic computing device can further include a user-facing camera (front-facing camera) 202. In one or more embodiments, the user-facing camera 202 can acquire images and/or video of the user as he/she performs hockey practice drills, such as the aforementioned target clearing drill.

[0040] In one or more embodiments, the one or more augmented reality elements includes at least one target. In one or more embodiments, performing an object tracking process on a hockey workpiece comprises performing an object tracking process on a hockey puck. In one or more embodiments, performing an object tracking process on a hockey workpiece comprises performing an object tracking process on a ball.

[0041] FIG. 3 shows another exemplary user interface showing augmented reality elements in accordance with disclosed embodiments. Electronic computing device 300 can comprise a tablet computer in one or more embodiments.

Date Recue/Date Received 2023-12-08 Electronic computing device 300 can be similar to electronic computing device 200 of FIG. 2. Continuing from the example shown in FIG. 2, a hockey workpiece 344 is set in motion along path 343 by hockey stick 342, which is manipulated by a user (e.g., 102 of FIG. 1). As can be seen in FIG. 3, the path 343 indicates that the hockey workpiece 344 (e.g., a hockey puck) moves such that it overlaps with augmented reality target 308 during the travel of the hockey workpiece. In response to the hockey workpiece 344 overlapping the augmented reality target 308, the processor within the electronic computing device 300 removes the augmented reality target from the electronic display 301, and increments the score 334 accordingly. The elapsed time 332 also continues to increment as the user performs the target clearing drill. Additional augmented reality targets 310, 304, and 306 remain to be cleared. In one or more embodiments, as augmented reality targets are cleared, new augmented reality targets can be rendered to allow the target clearing hockey practice drill to continue. In one or more embodiments, the new augmented reality targets can be rendered in a random, or semi-random location. In one or more embodiments, the rendering of a new augmented reality target in a semi-random location can include rendering a new augmented reality target in an opposite half of the display from the augmented reality target that was just cleared.

[0042] One or more embodiments can include: determining that at least one image of the hockey workpiece is overlapping with a region defined by the at least one target; modifying a performance metric based on the overlapping; and presenting the performance metric on the user-facing electronic display. One or more embodiments can include providing multiple targets, and further include:
determining that at least one image of the hockey workpiece is overlapping with a corresponding region defined by each of the multiple targets; modifying a performance metric based on the overlapping;

[0043] recording an elapsed time for each region to undergo an overlapping condition; and Date Recue/Date Received 2023-12-08

[0044] presenting the performance metric and the elapsed time on the user-facing electronic display.

[0045] FIG. 4 illustrates an example 400 of overlap in accordance with embodiments of the present invention. As shown in the example 400, an augmented reality target 405 is shown. A boundary region 402 is computed for the augmented reality target 405. In one or more embodiments, the boundary region is computed as the smallest circle that circumscribes the augmented reality target. This technique accommodates non-standard shapes of augmented reality targets, such as a "star" shape, a team logo, and/or other non-standard shapes. A hockey workpiece boundary region 404 is computed for a hockey workpiece 408. When a hockey workpiece is positioned such that overlap exists between the hockey workpiece boundary region 404 and the augmented reality target boundary region 402, an overlap region 412 is formed, that includes an area that is part of both the hockey workpiece boundary region 404 and the augmented reality target boundary region 402. When the overlap region 412 exists, disclosed embodiments register a target-clearing event, and perform a target clearing process. The target clearing process can include adjusting a performance metric such as a score, clearing (removing) the augmented reality target 405, and/or rendering a new augmented reality target in a new location on the display of the electronic computing device. In one or more embodiments, the score is adjusted as a function of the area of the overlap region 412. As an example, when the maximum size of overlap region 412 is less than half the area defined by hockey workpiece boundary region 404, one point may be awarded.
Similarly, if the maximum size of overlap region 412 is greater than or equal to half of the area defined by hockey workpiece boundary region 404, two points may be awarded. In this way, disclosed embodiments can promote accurate placement of a hockey workpiece, and update the score based on the accuracy of the placement.

[0046] FIG. 5 shows another exemplary user interface showing augmented reality elements in accordance with disclosed embodiments. Electronic computing device 500 can comprise a tablet computer in one or more embodiments.
Electronic computing device 500 can be similar to electronic computing device 200 of FIG. 2. FIG. 5 illustrates a speed-measuring application of disclosed embodiments. A user (e.g., 102 of FIG. 1) manipulates his/her hockey stick 542 to shoot the hockey workpiece (e.g., puck or ball) along a path 543 such that it crosses two augmented reality lines, indicated as augmented reality line 551 and augmented reality line 553. These lines are generated by a processor within electronic computing device 500. Disclosed embodiments determine the elapsed time for the hockey workpiece to traverse augmented reality line 551 and augmented reality line 553. As shown in FIG. 5, the hockey workpiece contacts augmented reality line 551 at position 541, and a time of contact with augmented reality line 551 is recorded. Similarly, the hockey workpiece contacts augmented reality line 553 at position 544, and a time of contact with augmented reality line 553 is recorded. A difference between the two times is computed. Based on the time difference, and an estimated distance between the two augmented reality lines 551 and 553, an estimated hockey workpiece speed is computed and rendered as shown at 557. Shot speed is an important aspect of hockey, and shot speed can significantly impact a player's effectiveness. A faster shot is harder for goaltenders to react to, increasing the likelihood of scoring.
Players with powerful and quick shots can capitalize on scoring opportunities even in tight spaces. Moreover, a high-speed shot increases the chances of generating rebounds off the goaltender's pads or creating opportunities for teammates to deflect the puck into the net. Disclosed embodiments provide a feature that allows users to develop their shot speed. In one or more embodiments, a history of the most recent shot speeds is displayed, as shown at 557 where the three most recent shot speeds are displayed.

[0047] One or more embodiments can include determining a hockey workpiece speed between two augmented reality elements from the one or more Date Recue/Date Received 2023-12-08 augmented reality elements; and presenting a hockey workpiece speed on the user-facing electronic display. One or more embodiments can include: recording hockey workpiece speed values corresponding to multiple shots; and presenting a hockey workpiece speed history on the user-facing electronic display. In one or more embodiments, a calibration procedure is performed prior to utilizing the speed-measuring function. The calibration procedure can include placing a meter stick on the floor surface, and then adjusting the position of the augmented reality line 551 and augmented reality line 553, such that the distance D
between the two lines is one meter. In this way, a speed in miles per hour, kilometers per hour, or other suitable unit can be computed based on the time required for the hockey workpiece to traverse both augmented reality line 551 and augmented reality line 553.

[0048] FIG. 6 shows another exemplary user interface including user-facing video. Electronic computing device 600 can comprise a tablet computer in one or more embodiments. Electronic computing device 300 can be similar to electronic computing device 200 of FIG. 2. FIG. 6 also shows a portion of a bracket 620 that may be used in one or more embodiments to clamp or squeeze the electronic computing device 600 to secure it to a stand (e.g., 120 of FIG.
1), as shown in FIG. 1.

[0049] The electronic computing device can further include a user-facing camera (front-facing camera) 602. In one or more embodiments, the user-facing camera 602 can acquire images and/or video of the user as he/she performs hockey practice drills, such as the aforementioned target clearing drill, and render the user-facing view 661 in a region of the electronic display 601. In this embodiment, the user (e.g., 102 of FIG. 1) can view himself/herself in a straight-on view as shown in view 661, where an image of the user 662, hockey stick 663, and hockey workpiece 664 are shown. Additionally, the hockey stick is also visible in a top-down view as shown at 642, along with hockey workpiece 644.
Moreover, multiple augmented reality targets, indicated as 608 and 610 are Date Recue/Date Received 2023-12-08 shown. A performance metric such as a score, indicated as 634 may also be shown, along with an elapsed time indicated as 632. Accordingly, disclosed embodiments enable a user to view his/her stick and hockey workpiece from multiple angles simultaneously. Viewing multiple video angles to analyze sports techniques provides several benefits for athletes and coaches. Multiple angles provide a more comprehensive view of an athlete's performance. Different perspectives help capture nuances and details that may be missed when analyzing from a single viewpoint. Furthermore, multi-angle video analysis enables a thorough examination of biomechanics. Coaches and athletes can assess body positioning, joint angles, and movement patterns from various perspectives, helping to identify areas for improvement. Moreover, viewing from different angles makes it easier to identify errors or inconsistencies in technique.
Whether it's foot placement, hand positioning, or body alignment, coaches can pinpoint issues and work with athletes on corrective measures. Thus, disclosed embodiments provide powerful tools for enabling hockey players to improve their skills.

[0050] FIG. 7A shows a side view of an assembly 700 including an electronic computing device and bracket in accordance with disclosed embodiments.

FIG. 7B shows a back view of the assembly 700 including electronic computing device 701 and bracket of FIG. 7A, as viewed from the direction indicated by arrow A in FIG. 7A. In FIG. 7A and FIG. 7B, a rear-facing camera 715 is visible. In one or more embodiments, the rear-facing camera 715 is used for acquiring downward images of an area in front of a user. In one or more Date Recue/Date Received 2023-12-08 embodiments, the electronic computing device comprises a tablet computer, where the tablet computer includes a front-facing camera and a rear-facing camera.

[0051] FIG. 8 shows a perspective view of an angled bracket 800 in accordance with disclosed embodiments. The angled bracket can include a straight portion 810. Attached at one end of the straight portion 810 is a hooked portion 814.
The hooked portion 814 is configured and disposed to hook over the edge of an electronic computing device such as a tablet computer. Attached at a second end of the straight portion 810 is an angled portion 818. In one or more embodiments, the angled portion 818 includes a reflective (mirrored) surface 823.
