Data input device by detecting finger's moving and the input process thereof

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;
• wherein the data is input through one or more of the first to the fourth directional inputs or combination of two or more of the first to the fourth directional inputs.

A data input device using finger action detection, the data input device being provided with a predetermined detection region in a terminal for an electronic device, comprising:

• a detection unit for detecting lateral pressing and vertical pressing at a reference location, which is indicated by contact or pressing of the finger with or on the detection region, and at a plurality of first indication locations, which are arranged in a radial direction around the reference location and are indicated, in the detection region, and generating a first directional input signal corresponding to the lateral pressing and a second directional input signal corresponding to the vertical pressing;
• and
• a control unit for determining a lateral pressing point and vertical pressing direction of the finger based on the first directional input signal and the second directional input signal, extracting data, assigned to the first directional input signal and the second directional input signal, from a memory unit, and inputting the extracted data, wherein the reference location can be displaced, and the first indication locations are moved along with the displacement of the reference location,
• wherein the reference location and the first indication locations are disposed within a range that can be covered with one finger;
• and
• the detection unit can distinguish and detect an entire input mode in which lateral pressing input or vertical pressing input is performed on one of the first indication locations while the finger is placed on the detection unit, and a partial input mode in which the lateral pressing input or the vertical pressing input is performed on one of the first indication locations.
