1. An input apparatus comprising:

  • a casing;

    a sensor section including sensors consisting ofa first acceleration detection section to detect a first acceleration value ax of the casing in a first direction x,a first angle-related value detection section to detect a first angular velocity value ω

    ψ

    as a value related to an angle of the casing about an axis in a second direction y different from the first direction x,a second acceleration detection section to detect a second acceleration value ay of the casing in the second directions y, anda second angle-related value detection section to detect a second angular velocity value ω

    θ

    as a value related to an angle about an axis in the first direction x; and

    a calculation means for calculating a first velocity value Vx of the casing in the first direction x based on the detected first acceleration value ax and the detected first angular velocity value ω

    ψ

    detected, and for calculating a second velocity value Vy of the casing in the second direction y based on the detected second acceleration value ay and the detected second angular velocity ω
