Touch panel input device and gesture detecting method
First Claim
1. A touch panel input device, comprising:
- two resistive films which are arranged to face each other with a minute gap therebetween;
a first electrode pair formed by electrodes provided at the edges of one of the resistive films that face each other;
a second electrode pair formed by electrodes provided at the edges of the other one of the resistive films that face each other and extend in directions perpendicular to the first electrode pair; and
circuitry configured to;
apply voltages between the first electrode pair and between the second electrode pair;
measure divided voltages which are divided at two touch points with respect to the first electrode pair and the second electrode pair when the resistive films are caused to contact each other by being touched at the two touch points;
measure currents that flow between the first electrode pair and between the second electrode pair when the touch occurs, wherein the currents indicate distance between the two touch points; and
discriminate trajectories of the two touch points based on the values of the measured divided voltages and currents.

Abstract
Detection of complex input by two touched points are enabled to be detected by a resistive film type touch panel input device equipped with two resistive films facing each other with a minute gap therebetween; a first electrode pair; a second electrode pair extending in directions perpendicular to the first electrode pair; means for applying voltages between the first electrode pair and between the second electrode pair; means for measuring the voltage which is divided at two touch points with respect to the first electrode pair and the second electrode pair, when the resistive films are caused to contact each other by being touched at two points; means for measuring currents that flow between the first electrode pair and between the second electrode pairs when the touch occurs; and discriminating means, for discriminating the trajectories of the two touch points based on the values of the measured voltages and currents.
