Problems solved by technology

[0011] However, touchscreens have the same disadvantages as touchpads regarding sensitivity to varying levels of pressure
Additionally, touchscreens are limited in durability, making it difficult to use them as a mouse or input device for recognizing multiple pressures
[0012] Therefore, the exemplary input device described above cannot distinguish the pressure applied by the user and is not sensitive to the application of different pressure levels

Embodiment Construction

[0037] Embodiments of the present invention will be described below with reference to the drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

[0038] Pressure sensor array devices and methods for tactile sensing are described.

[0039] The present invention uses an array of multiple tactile inputs capable of measuring location information indicating the point the user pressed and the degree of force applied when the user pressed that point.

[0040] The tactile input array is capable of continuously receiving information about a plurality of positions and pressures passing through the array during a user's pressing on the array. Since the tactile input array must sense sensitive movement of the finger, it must be designed below the finger's minimum resolution, which in one aspect of the invention is below 1 millimeter (mm).

[0041] In the tactile input array,...

Abstract

An input apparatus and method for tactile sensing is provided. 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.

Description

technical field [0001] The present invention relates to techniques for supporting haptic devices, and more particularly, to a pressure sensor array device having multiple input levels usable in a compact device. Background technique [0002] In currently used mobile terminals, a keyboard is used as a main input device. Typically, keyboards consist of mechanical switches in a two-dimensional array. The keyboard has noticeably low spatial resolution. Only two-dimensional positions can be used as input values ​​in the keyboard. [0003] The use of mechanical switches allows ON / OFF input only over a predetermined area, and the user may feel very uncomfortable pressing the switch with his or her fingers. The use of a conventional keyboard is limited in that it accepts input in predetermined key areas. Also, traditional keyboards cannot be used for other purposes. [0004] Conventional keyboards are capable of receiving input based only on predetermined keystrokes. Therefore...
