Patent ID: 8436817

Claim:
A data input device using finger action detection, comprising: a detection unit provided in a predetermined input region formed on one side of a casing of a terminal for an electronic device, the detection unit processing first directional input that generates a first directional input signal through detection of lateral pressing in a predetermined radial direction by a finger placed at a reference location in the input region, second directional input that generates a second directional input signal through detection of vertical pressing in a predetermined direction in a state in which the finger is placed at the reference location, third directional input that generates a third directional input signal through detection of tilt pressing, which is performed by diagonally pressing the finger in a predetermined direction, in a state in which the finger is placed at the reference location, and fourth directional input that generates a fourth directional input signal through detection of a tilt input, which is performed by tilting the entire finger in a predetermined direction, in a state in which the finger is placed at the reference location; and a control unit configured to determine input locations of lateral pressing direction, vertical pressing direction, tilt pressing direction and tilting direction of the finger based on the first to fourth directional input signals, extract data assigned to the corresponding input locations from a memory and input the extracted data.
