Claim Text:
1. An input device, comprising: a detection unit that includes acceleration sensors and detects a vibration that is generated by tapping on a body of a user and transmitted through the body of the user; and an input information identification unit that refers to the vibration and identifies a tap position based on how the vibration varies according to a length of a transmission path of the vibration from the tap position to the detection unit, wherein the detection unit comprises a first detection unit provided on a tapping side, the first detection unit comprising a first acceleration sensor among the acceleration sensors, and a second detection unit provided on a tapped side, the second detection unit comprising a second acceleration sensor among the acceleration sensors, and the input information identification unit identifies the tap position based on a difference between a time when the first detection unit detects the vibration and a time when the second detection unit detects the vibration.
