This study found that the use of a smart watch to detect the variance and zero-crossing rate of movements in children with ADHD is a very promising method to assist in the diagnosis of ADHD. A smart watch that measures six axes of movement (three for the gyroscope and three for the accelerator) was used. We used our own application program (app) written in Java for the recording. It can be used to solve the problems of the traditional diagnosis of ADHD based on the behavior rating scales, which is over-subjective, and inaccurate.

Diagnosis of Attention-Deficit/Hyperactivity Disorder by Smart Watch (or Treatment Chair) - Scientific and objective diagnosis and assessment.
1)The smart watch can be used to solve the problems of the traditional diagnosis of ADHD based on the behavior rating scales, which is over-subjective, and inaccurate.
2)A smart chair with piezoelectric material inside is potentially an objective and useful method for evaluating the therapeutic effects of ADHD medications.
