Data Acquired by a Single Object Sensor (IMU) of Table Tennis Forehand Strokes
The sensory data were collected from a total of 16 Table Tennis players mixed gender, aged between 19 and 38 years, who used the IMU mounted Racket. We considered the Basic, Topspin, and Push as the sample type of performed Forehand strokes. The Table Tennis Forehand strokes quality evaluation values were collected from a total of 3 Table Tennis highly educated and ranked coaches who manually scored the performed strokes based on the experiment evaluation metrics. The players used the IMU mounted racket when samples were collecting. Each subject's performance was evaluated, scored, and labeled by the coaches who placed around Table Tennis's table. Acquiring simultaneously by the Racket, the strokes' evaluation metrics values, and their labels, each player carried out a predetermined stroke performing protocols when data was gathering. Capturing order of the samples are: 1) the players started performing strokes, 2) paused for five seconds by the coaches at the end of each stroke performing, 3) stored the sensory data by the software into a single CSV file, 4) labeled and scored the players' performance by the coaches manually.
