Title:
INPUT DEVICE AND MULTIPLE POINT LOAD DETECTION METHOD EMPLOYING INPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/058005
Kind Code:
A1
Abstract:
An objective of the present invention is to provide an input device that can obtain the load on each of a plurality of press points which are simultaneously pressed, and a multiple point load detection method employing the input device. An input device (1) according to the present invention comprises: a static capacitance touch panel sensor (4) which is capable of detecting a press location upon an operating surface; a plurality of load sensors (A-D) which output a sensor output corresponding to a load; and a control unit (2) which computes the load on each of a plurality of press points upon the operating surface which are simultaneously pressed. In particular, with the present invention, it is possible to derive the load on each press point even if the number of the plurality of simultaneously pressed press points is the same as the number of load sensors.
