Problem Statement: In table tennis, the service is crucial. Often players try to “jam” the opponent with a serve along the centerline of the table. However, with the speed of the ball and heavy spin generated, it is very difficult for the players or umpire to determine if a serve was “in” or “out”. With organizations like NCTTA, a doubles match is used as a tiebreaker, so one missed call can affect which teams move on in competition. Proposed solution : A table tennis fault serve detector integrated in the table beneath the net which will detect if the ball is “in” or “out”. The result will be displayed wirelessly to the umpire so as to not distract the players. Components: Sensor: The choice of sensors must not interfere with gameplay or change the composition of the table and must be able to detect the bounce of the ball. We are leaning towards vibration sensors which would record a spike in the signal on either the left or right of the table close to the middle line. Optical sensors would be ideal for accuracy if we can find a way that it won’t hinder gameplay. Processing: We will interpret the sensor data for the validity of the serve and also account for the racquet hitting the table. We plan on doing this mostly in hardware, the other option being feeding data into a microcontroller and processing in software. Power supply: The power supply must last the length of a best-of-seven game match, which can take up to 45 minutes. Battery power is a possible solution. Wireless Output indicator: We propose a wireless output indicator as placing it anywhere on the table, even the bottom left/right side might affect the player’s peripheral vision. Since professional games are fast-paced, the delay to the display must be minimal. Demo: Since it isn’t feasible to get an actual table tennis table for demo, we can calibrate the system for a regular study table in ECEB and add a net and tape a middle line.
