FIELD OF THE INVENTION
The present invention relates generally to sports training devices or systems. More particularly, the present disclosure relates to a wireless basketball shot tracking system, method and processor-readable medium involving a hands-free-portable portable electronic device that is in wireless electrical communication with a shot detector for instructing a basketball player where to shoot from and automatically tracking real-time shooting percentages of the basketball player from the instructed shooting locations.
BACKGROUND OF THE INVENTION
Basketball is a popular sport played by professionals and amateurs alike and is a wide-viewed sport that is typically broadcasted on national and local television. The game is often played in schoolyard playgrounds, at parks, in residential driveways, and at local recreational centers. An organized basketball game is played on a basketball court having a playing surface that consists of a generally rectangular floor and two basketball goals that are disposed at opposite ends of the basketball court and typically positioned ten feet from the court. A basketball goal includes a round metal rim or hoop that is secured to backboard which is attached to a frame, and netting that is suspended from the rim. The diameter of the basketball hoop is larger than that of a basketball to allow the ball to fall through the hoop during play. The playing surface includes a number of geometric markings, such as circles, arcs, and a variety of straight and curved lines, that define the playing boundaries prescribed by game rules. Teams compete against each other over the course of 2 to 3 hours where players assume offensive and defensive roles while attempting to score points by throwing a basketball through the opponent's basketball hoop. The team with the most points wins.
During the basketball game, players normally employ guard, center and forward positions on the basketball court. More particularly, the playing positions are typically defined as point guard, shooting guard, small forward, power forward, and center. Each player assumes a particular position based on the player's performance skills. For example, the player assigned to a point guard position is usually the person who is the team's best basketball handler and passer, and a shooting guard is usually the team's best basketball shooter.
Many individuals simply enjoy the opportunity to shoot basketballs without having to follow particular rules or participate in officiated games. As such, the game is often played with fewer players and basketball shots are made on a basketball goal that is often attached to a garage, or fixed to a frame that is secured to a base having a ballast. Whether on a team or playing solo, basketball players consistently strive to gain the satisfaction of improving the frequency of successful basketball shots.
Players constantly train to perfect their shooting and handling skills of the basketball on the court. A player must develop good balance, coordination, concentration, form and technique, and must also master the ability to make successful shots on goal from various positions on the basketball court. Players spend countless hours practicing a variety of different shots that generally include two-handed shots, one-handed shots, jump shots, hook shots, lay-up shots, one-handed underhand, three-point shots, and bank shots. Since repetitive shots are often made from a single location on the basketball court, the practicing player often becomes accustomed to this level of comfort thereby diminishing the player's ability and confidence to make successful shots from different locations on the court. To improve the frequency rate of successful shots made on basketball goal, it is important for individual players to practice their shooting skills by shooting basketballs from different locations on the basketball court. To better assist individual players in improving their shooting skills, and gaining confidence in their shooting abilities, many players have employed the help of shooting aids.
There are a number of shooting aids on the market today that are designed to help a basketball player improve his/her shooting skills. Examples of shooting aids include: video camera based tracking systems that capture images of shot trajectories; mechanical braces used on an individual's arm, wrist or hand to help position the extremities in proper angle for successfully shooting a basketball within a hoop; spot location devices, such as floor mats or position markers that are placed on a playing surface to indicate shot locations to a player from where to make basketball shots; gesture recognition systems that include a plurality of markers fixed to a person's body to permit a camera to capture and analyze body movements during play; sophisticated computer analysis systems including complex software used for analyzing a basketball player's performance; and finally, a variety of self-contained electronic devices that are attached to a player to provide an audio or illuminated signal to indicate improper positioning of a player, or an indication of a successful shot being made.
Many conventional shooting aid devices or systems are too complex or sophisticated to integrate for use, are expensive, and require time consuming assembly. Other devices are bulky to use, non-user friendly, and are simply ineffective in assisting basketball players for improving their shooting skills. Further, such devices fail to provide a method of being able to keep track of a person's shooting percentages during a basketball shooting session, and to provide a historical log of information for a person to review and analyze to help determine whether improvements are being made over time. Conventional aids that do provide a data log, fail to assist a player in improving their shooting skills from different shooting locations on the basketball court.
Accordingly, what is desired is a basketball shooting aid system that improves a person's shooting performance from multiple locations on a basketball court, monitors and records real-time shooting percentages of basketball players during shooting sessions, and provides historical data for performance review.

The user secures the display unit 10, 100 to the wrist using the wrist attachment 26. The display unit 10, 100 may be secured to either wrist, however, the display unit 10, 100 may be worn on a user's non-shooting wrist so as not to interfere with the person's shooting motion. With a finger of one hand, the user begins to program the display unit 10, 100 where the player enters a number of programs and a number of shooting locations, each program being associated with one or more shooting location on a basketball half court. To begin a shooting session, the player enters the play mode by depressing the mode 19, 119 button on the display unit 10, 100, respectively. Upon selecting a pre-entered program, a blinking indicator is shown on the symbolic half court which is displayed on the display 16, 116 of the display unit 10, 100. The player physically stands on the playing surface at the spot correspondingly identified by the blinking indicator on the display 16, 116 and attempts to shoot a basketball into a hoop 71 of a goal 70 from the indicated location. Three operative measurements are made to determine whether the shot was a made basketball shot or a missed basketball shot.
The three operative measurements include a vibration measurement, a vibration-paddle measurement, and a paddle measurement. In a vibration measurement, when the basketball hits the rim 71 or backboard 74 of the basketball hoop 70, the vibrations are measured by one or more vibration sensors 49 disposed within the shot detector 40. When the vibration sensor 49 is activated, a signal is generated, and the generated signal is transmitted to the display unit 10, 100 via a RF transmitter. The RF receiver of the display unit 10, 100 receives the transmitted signal and processes the signal to determine a missed basketball shot. The information is recorded and stored in memory. In the event a ball is not heavy enough to activate the vibrations sensor or sensors 49 when the ball hits the rim 71 or backboard 74, a user may activate an airball button 118 located on the display unit 10, 100 to record a missed shot.
In a vibration-paddle measurement, when a basketball comes in contact with the rim 71 or backboard 74, the vibration sensor 49 senses the impact and generates a signal. As the ball continues to pass through hoop 71, the ball engages paddle sensor 44 and paddle sensor 44 pivots to generate a signal. Both signals are transmitted, via the RF transmitter, to the RF receiver for processing the signals to determine a made basketball shot. The display unit 10, 100 may include a set amount of time between the vibration sensor 49 and the paddle 44, such as 3 seconds. If the vibration sensor 49 in the shot detector 40 senses a vibration but the basketball does not activate the paddle 44 during the set three seconds, the display unit 10, 100 processes the signal to determine a missed basketball shot. The information is recorded and stored in memory.
In a paddle measurement, when a basketball passes directly through the hoop 71 but does not come in contact with the rim 71 or backboard 74 to trigger the vibration sensor 49, the paddle 44 is activated to generate a signal. The RF transmitter transmits the signal to the receiver of display unit 10, where the display unit 10, 100 processes the signal to determine a made basketball shot. The information is recorded and stored in memory. It will be noted that the recorded data is stamped with a time and/or date, and may also be stamped with a shooting session identifier. Thus, made basketball shots, missed basketball shots and dates are recorded and stored in the display unit 10. Shot data may also include shooting locations the basketball was thrown from.
Shot detector 40 wirelessly transmits data, via a transmitter, to the display unit 10. The display unit 10, 100 receives the data via, a receiver, and processes the information to determine whether a basketball was successfully made or missed. Shot data is collected during a shooting or playing session and the data is stored in memory to provide real-time and long-term tracking. The data may be uploaded to a computer via, USB port 28, for processing the data, storing the data, transferring the data or for generating data charts or graphs. The wireless tracking system of the present invention may include receivers/transmitters or transceivers for providing RF communication between a shot detector 40 and display unit 10, 100. The wireless tracking system may include any type of wireless transmission technology, including, but not limited to, Wi-Fi, 3G, 2G, 2.5G, 4G, WiMax, and Bluetooth technology.
In an alternative embodiment, display unit 10, 100 may incorporate the use of motion technology. For example, display unit 10, 100 may include an accelerometer to provide spatial data as to when and possibly where a user is shooting the basketball. The motion technology system could use infrared technology, or wireless communication. The motion technology provides the ability to track the shooting data of a user without the user relying on the directive instructions provided by display unit 10, 100.
The invention further contemplates a non-transitory processor-readable medium (for instance, the memory of the hands-free-portable electronic device or display unit 10) having processor-executable instructions stored thereon that, when executed by an electronic processor (for instance, the processor of the display unit 10), cause the processor to carry out the method claimed herein.
Since many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalence.
