MOTION DETECTING DEVICE, RECORDING SYSTEM, COMPUTER READABLE MEDIUM, AND MOTION DETECTING METHOD

摘要

A motion detecting device includes: a first detecting unit that detects a state of a writing hand of a writer based on first data output depending on the state of the writing hand from a first sensor; a second detecting unit that detects a distance between the writer and a recording medium based on second information output from a second sensor; a determining unit that determines that the writer is writing on the recording medium when the state of the writing hand detected by the first detecting unit is a predetermined state and the distance detected by the second detecting unit is smaller than or equal to a predetermined threshold value; and an output data generating unit that generates output data based on a state of the writer determined by the determining unit.
