A compact convenient hand-held, accelerometer-based computer control device is utilized to control on-screen animated characters presented by a comer-driven display in which the movement, persona, style, and voice of the character is controlled. The control device detects accelerations which are used to provide the on-screen character a particular persona, style or voice quality determined by the user. Character motion is determined by acceleration patterns based upon a learned language. The system requires only a series of easily learned hand movement patterns for corresponding character control.
