Operation input device and method, program, and electronic apparatus

摘要

An operation input device includes: angular velocity detecting means for detecting an angular velocity; relative velocity detecting means for contactlessly detecting a relative velocity to a target object; distance detecting means for detecting a distance to the target object; and computing means for computing an amount of movement based on the angular velocity, the relative velocity, and the distance.

主权项

1. An electronic apparatus, comprising:
circuitry configured to: detect an angular velocity of the electronic apparatus; contactlessly detect a relative velocity of the electronic apparatus in reference to a target object; detect a distance of the electronic apparatus to the target object; and compute an amount of movement of the electronic apparatus based on the angular velocity, the relative velocity, and the distance, without communicating with another object; the circuitry being further configured to: acquire a peak frequency of vibration generated at sliding of the electronic apparatus in reference to the target object based on the angular velocity; acquire a correction value based on the detected frequency; and compute a corrected velocity at the sliding based on the correction value and the angular velocity.
