1. A three-dimensional data input device for a computer having a display screen, said three-dimensional data input device comprising:

  • a plurality of angular velocity sensors arranged on a plurality of axes, respectively, said axes being positioned so as to have a given angle therebetween, each of said angular velocity sensors detecting an angular velocity about the corresponding axis and producing an angular velocity signal indicative of said detected angular velocity; and

    angular data generating means for producing angular data each indicative of a rotation angle about the corresponding axis, based on the corresponding angular velocity signal and further based on the angular velocity signal relative to the axis other than said corresponding axis,wherein said computer rotates a corresponding object to the screen corresponding to said angular data.
