Abstract

An input apparatus and method for tactile sensing are disclosed. The input apparatus includes a sensor array for outputting input data in an array format according to a touch input, and a controller for obtaining first input data for a first input from the sensor array if the first input above a predetermined pressure is imposed on the sensor array, for obtaining second input data for a second input from the sensor array if the second input above a predetermined pressure is imposed on the sensor array, for generating third input data indicating an input characteristic by comparing the first input data and the second input data, and for operating according to a program based on the third input data.

Claims
