The present disclosure relates to the field of sports technology. More particularly, the present disclosure relates to identifying one of a ball impact and a custom tap based on at least one sports data collected by at least one smart sticker mounted on a sports equipment.
The following description of related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section be used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of prior art.
With the improvement of technology and standard of living of people, there has been more and more people indulgence in sports, especially in cricket, tennis, badminton, baseball, ice hockey and other ball games. When participating in such games, people exercise and improve their physical fitness, along with the spirit of competition by participating in tournaments. With further developments in computer technology, data analysis for sports in recent years has also vigorously developed. Through the collection and analysis of motion data, participants can get physical data of the sport, as well as suggestions for improving movements and tactics in order to enhance the success rate.
One of the examples of data collection and analysis in the field of cricket is for edge detection, wherein in order to determine whether or not the ball has hit the bat, audio data from the bat around the time of the impact is required to be acquired and assessed. This is then assessed in view of the camera feed from various cameras placed at different angles and location in the stadium. Together, such audio and camera technology is used for edge detection.
Also, there are many solutions for providing such sports data and analysis of said sports data, but these currently known solutions have many limitations and there is a need for improvement in this area of technology. The known solutions typically use or rely on piezoelectric sensors for detecting an impact on a sports equipment. Typically, three piezoelectric sensors are used to sense impact data and the same is processed to identify the impact. Use of multiple sensors is however disadvantageous for numerous reasons. Firstly, piezoelectric sensors are usually temperature sensitive, so the readings from piezo sensors vary over time based on the temperature. Secondly, the output from piezoelectric sensors are very low so external additional circuitry is required to be connected to retrieve readings. Piezoelectric sensors are highly dependent on assembly and placement, and readings may vary in different placement and thus reliability on such data is an issue. Therefore, there is a requirement to provide more efficient and effective sports data to identify ball impact and other impact such as tap.
This section is provided to introduce certain aspects of the present disclosure in a simplified form that are further described below in the detailed description. This summary is not intended to identify the key features or the scope of the claimed subject matter.

As shown in
In order to identify one of a ball impact and a custom tap on the sports equipment, at least one sports data is collected by at least one smart sticker mounted on the sports equipment. Thereafter, said collected sports data is transmitted to the stump box [102]. The stump box [102] thereafter identifies one of the ball impact and the custom tap based on the sports data, wherein the sports data comprises at least an acceleration data.
Further, an exemplary block diagram of a smart sticker [104] for identifying one of the ball impact and the custom tap, in accordance with exemplary embodiments of the present disclosure is shown in
Further, in an implementation each of the one or more accelerometer sensors [202] may be a low power accelerometer sensors configured to determine velocity of the sports equipment in a low power mode of operation. The invention encompasses that each of the one or more accelerometer sensors may be a 3-axis high frequency accelerometer sensor. Also, in another implementation the one or more accelerometer sensors [202] are configured to collect at least one acceleration data associated with a sports equipment (such as the cricket bat) [106]. Also, the at least one acceleration data may include but not limited to at least one data associated with an impact on the sports equipment. The data associated with the impact comprises an indication of the impact/tap detection on the sports equipment. Also, the data associated with the impact is determined by the one or more accelerometer sensors [202] based on an analysis of one or more samples of the one or more accelerometer sensors [202] for a fixed period of time, a detection of at least one spike summation value based on the analysis of the one or more samples and a comparison of the at least one spike summation value with at least a low threshold value.
For example, a spike in each of the X axis, Y axis and Z axis is determined based on taking sample acceleration values along each of the X axis, Y axis and Z axis of an accelerometer, respectively. Further, a spike summation value is calculated as a total spike (TSi) based on the spike in each of the X axis, Y axis and Z axis. Further at least one total spike value is compared with at least a low threshold value to identify an impact. For example, in an implementation, if one or more total spike values exceeds the low threshold value for a fixed time period, an impact is detected.
Further, each of the one or more inertial measurement unit [204] comprises at least one multi-axis accelerometer and at least one multi -axis gyroscope. The multi-axis accelerometer may be a 3-axis accelerometer and the multi -axis gyroscope may be a 3-axis gyroscope. The one or more inertial measurement unit (IMU) [204] is configured to collect at least one linear dynamic motion data and at least one angular dynamic motion data of the sports equipment [106], wherein the at least one linear dynamic motion data and the at least one angular dynamic motion data is collected by the at least one multi-axis accelerometer and the at least one multi-axis gyroscope, respectively. In an implementation, a twist of the sports equipment [106] is further identified based on the data collected by the multi-axis gyroscope and a velocity of the sports equipment [106] is further identified based on the data collected by the multi-axis accelerometer. Furthermore, the present disclosure encompasses these and other sensors, data from which may be used to determine parameters such as a launch angle, a back-lift angle, etc.
More specifically, in a cricket match, data such as gyroscope values and accelerometer values from IMU sensors, values of high frequency accelerometer sensors and/or gravity components etc. are used to determine at least one of a Backlift angle, Backlift direction, Handedness of Batsman, Intended Direction of Shot, Face Angle, Impact Determination, Forward Swing Angle, Twist Angle, Follow Through Angle, Velocity at Impact, Impact Localization, Impact Differentiation, Launch Angle and the like.
Also, in an implementation, the sensors placed in the smart sticker [104] are connected to a microcontroller via an interface. For instance, multi-axis (or for instance 6-axis) sensors are connected to the microcontroller via Serial Peripheral Interface (SPI). In another instance, each of the Low power Accelerometer is connected to the microcontroller via Serial peripheral Interface (SPI). In yet another instance, a Fuel Gauge is connected to the microcontrollervia Inter Integrated circuit (I2C) Bus.
Further, the battery [206] of the smart sticker [104] may comprise of a wireless battery receiver and charger, a Li-ion thin film battery, a dual buck regulator, and a battery protector IC. The batter protector IC is used to protect the battery from over-voltage, under- voltage, over charge current, over discharge current and short circuit. In an implementation the battery [206] is charged via wireless charging and a specific LED indication is provided to indicate charging. Also, a count of no. of charging and discharging cycles are calculated and stored in the memory unit of the smart sticker [104] as well as transmitted to the stump box [102] as a health packet/data. Further, one or more LED indications are also provided to indicate a battery percentage.
The Bluetooth antenna [208] of the smart sticker [104] is configured to establish a Bluetooth connection with the one or more stump boxes [102] placed in a sports field. In an implementation, a striker side and non-striker side in a cricket match is identified based on a Bluetooth signal strength of the smart sticker [104] connected with the stump box [102]. For example, a striker side strength is a threshold value of Bluetooth signal strength and once the smart sticker [104] is paired with one stump box [102] placed near the stumps, the Bluetooth of the smart sticker [104] blocks detection and pairing from a stump box [102] present at the opposite end unless batsman takes up position at opposite end. Also, in such implementation a data acquisition from the smart sticker [104] is enabled only if the Bluetooth (BLE) is connected and the signal strength is greater than the striker side strength, also there is no storage of sports data in case of poor connection. Further, in such implementation in an active mode of the smart sticker [104], the data acquisition may happen (both striker side, non-striker side) and then after a ball impact collected data is transmitted via the BLE in case of good signal strength or stored in the memory unit of the smart sticker [104] in case of poor signal strength.
Also, the invention also encompasses that the smart sticker [104] establishes a direct connection with a user device such as a mobile phone, to transmit the data collected by the sensors of the smart sticker [104] to the user device. This connection may be a wireless connection, and for example, via the Internet. The user device may then assess the data received from the smart sticker and display the assessed data on the user device. The user device may also transmit the assessed data to one or more other user devices.
Further, the smart sticker [104] is configured to operate in a number of modes such as a standby mode, a sleep/deep sleep mode, an active mode and a storage mode. For example, the smart sticker [104] is configured to, initially, operate in a sleep mode wherein only the at least one low power accelerometer is active in the sleep mode. The smart sticker [104] is configured to wake up from the sleep mode upon the low power accelerometer detecting an acceleration/motion above a predetermined threshold.
Further, the operating modes of the smart sticker [104] are explained as below:
1. Standby Mode: In Standby Mode following are the states of the components of the smart sticker [104]:
Furthermore, if any motion > threshold acceleration values for 5s is identified by the IMU of the smart sticker [104], the smart sticker [104] enters in the Standby Mode from the Sleep mode and the Bluetooth operates in a Wakeup and Advertise state.
Also, if a Timeout (such as an inactivity of the sports equipment or for example no motion in a cricket bat) for > 10 min is identified, the smart sticker [104] enters in the Standby Mode from the Active mode. Also, in Standby mode the smart sticker [104] waits for a batting stance/state.
2. Active Mode: In Active Mode following are the states of the components of the smart sticker [104]:
Furthermore, if batting stance is identified, the smart sticker [104] enters in the Active Mode from the Standby mode and starts the data acquisition. Also, if an active Bluetooth connection is identified, the smart sticker [104] enters in the Active Mode from the Storage mode. Also, in Active mode the smart sticker [104] is configured to acquire data and on shot detection the data (i.e. the sports data) is transmitted to the stump box [102].
3. Sleep Mode: In Sleep Mode following are the states of the components of the smart sticker [104]:
Furthermore, if no motion for 10 min or Low Battery i.e. Battery < 5%, is detected the smart sticker [104] enters in the Sleep/Deep sleep mode from one of the Standby mode and the Storage mode. In such case the data is stored in the memory unit of the smart sticker [104]. Also, in Sleep mode the smart sticker [104] is in a Sleep state and waits for wakeup.
4. Storage Mode: In Storage Mode following are the states of the components of the smart sticker [[104]:
Furthermore, if no active Bluetooth connection is found the smart sticker [104] enters in the Storage Mode. In Storage mode, the smart sticker [104] is configured to acquire data and on shot detection the data (i.e. the sports data) is stored in the memory unit (for instance the NVM of the smart sticker).
In an implementation, for mode transition the smart sticker [104] is configured to detect an active sports equipment (or for instance an active/moving bat) and a passive/still sports equipment (or for instance a passive bat) in real time. If the bat is passive (i.e. no motion) for greater than a configured idle time limit (for example - 10 min) the sensors of the smart sticker [104] are in a shutdown state and the smart sticker [104] enters in the deep sleep/sleep mode. The sensors of the smart sticker [104] are configured to wake up on movement or a pre-defined motion signature. If the bat is active (any motion) for greater than a configured time limit (for example 5s), the sensors of the smart sticker [104] are configured to receive a trigger (interrupt) from the IMU to wake up and reinitialize.
Furthermore, the smart sticker may be in a circular shape and be placed anywhere on the sports equipment such as on the bottom left or right side of the bat. Also, for the smart sticker [104], the no. of days from full charge to full discharge may vary between 3-5 weeks. Also, in an implementation, the max number of shots in full charge may be upto 500 shots and the number of shots stored in the memory unit may be at least 100 shots. Also, the smart sticker [104], is further configured to synchronize the data collected from various sensors and/or units of the smart sticker [104] to provide the stump box [102], the at least one sports data associated with the sports equipment [106]. For example, the data collected via the IMU [204] and the data collected via the one or more accelerometers [202] (for instance a high acceleration data) is synchronized at a time of a ball impact on the sports equipment [106].

Further, the processing unit [304] is configured to identify, one of the ball impact and the custom tap, wherein the ball impact is identified based on the positive indication and the custom tap is identified based on the negative indication.
For example, in an implementation AXs, AZs is identified as a set of sampled acceleration data in X axis and Z axis (i.e. identified acceleration pattern) correspondingly from an accelerometer sensor and AXr, AZr is a set of reference acceleration data in X axis and Z axis (i.e. preconfigured acceleration pattern) correspondingly for a tap/impact. A correlation for X axis and Z axis acceleration data is then computed and correlation coefficients (i.e. correlation values) for accelerometer sensors are determined based on the identified acceleration pattern and the preconfigured acceleration pattern.
Further, if mean of the correlation coefficients is greater than a Tap correlation threshold, then a negative indication is generated and the impact is considered as “Tap”, else a positive indication is generated and the impact is considered as “Ball Impact”.
