We conducted a literature review and determined the specifications of an ideal virtual accelerometer in order to design an economical and portable acceleration measurement system that can be used in amateur sports. As a result, the performance of the ideal and virtual accelerometer was determined to have a sampling frequency of 1000 Hz, an acceleration of 200 G (1962 m/s2), and duration of 40 ms. The rotation tests for comparing the ideal and virtual one were conducted on three existing sensors using a rotating impact test system. The results showed that the minimum requirements were a sampling frequency of 200 Hz, a maximum acceleration of 200 m/s2 with a duration of 27 ms. If a sensor also holds，a Bluetooth® communication device, and is dimensions of 30 × 30 × 15 mm or less, it will be used in the storage system of our goal.
