A data input device transmits an input signal according to the position touched by an operating finger and an operation performed by the finger. The data input device includes a finger rest unit on which the finger is placed; a finger position sensor capable of detecting one of three positions, such as right, left, and middle parts, of the finger rest unit touched by the finger; and a vertical switch switchable by the vertical movement of the finger rest unit. The finger rest unit is formed so as to support the finger by two rotary bodies having a rotary axis extending in the longitudinal direction of the operating finger. Another aspect is a method of controlling information equipment having an output screen which displays information and a data input device which moves a cursor or a pointer displayed on the output screen to the predetermined position.
