Input device and multi-point load detection method employing input device

Abstract

[Problem] An objective of the present invention is to provide an input device and a multi-point load detection method with which it is possible to obtain a load at each of a plurality of pressure points which are simultaneously pressed. [Solution] This input device (1) comprises: a capacitance touch panel sensor which is capable of detecting a pressure location of each of a plurality of pressure points (A, B) which are pressed simultaneously upon a console surface (4a); a load detection sensor which is capable of detecting a center of gravity location and a center of gravity load of each pressure point (A, B); and a control unit which is capable of computing each load (z1, z2) at each pressure point (A, B) on the basis of location coordinates (x1, y1), (x2, y2), center of gravity coordinates (X, Y), and center of gravity load (Z), of each pressure point.

Description

technical field [0001] The present invention relates to an input device mounted on a portable device or other electronic equipment, and operated by touching an operation panel with a finger or the like. Background technique [0002] Each of the following Patent Documents 1 describes an input device capable of detecting position coordinates and load of a pressed point when an operation is performed on an operation surface with a finger or the like. [0003] In these patent documents, the pressing point capable of detecting both the position coordinates and the load is one point, but there is no description about the detection of the position coordinates and the load at each pressing point when a plurality of positions are simultaneously pressed. [0004] Prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent Laid-Open No. 2009-87311 [0007] Patent Document 2: Japanese Patent Laid-Open No. 2010-146206 [0008] Patent Document 3: Japanes...
