Abstract

A portable information displaying apparatus includes an information display unit provided on a first surface of a casing and including a pointer displayed thereon. The apparatus further includes a controller for controlling the movement of the pointer. In one embodiment, the controller is a mouse positioned on the bottom surface of the apparatus which rotates in a freely-selected direction. Alternatively, the controller can comprise first, second, and/or third roller members, each usable to control movement of the pointer along one axis. In addition, a dial member can be provided which is rotatable about an axis perpendicular to the upper surface of the apparatus. These elements of the controller are positioned along side walls of the apparatus. In another embodiment, a track ball and/or first and second slide levers and/or a joystick is provided along a side wall of the apparatus to control the movement of the pointer. In addition, a click button can be provided which is usable in association with the pointer to input information into the apparatus.
