Portable information terminal apparatus, mobile wireless terminal apparatus, and sensor control method
View Patent ↗A touch sensor detects contact input by a finger or the like, and includes two sensor modules. Each of the sensor modules has many sensors arrayed linearly. The operation state of each sensor module is set under the control of a control unit. When a user touches a sensor of the sensor module, the control unit energizes only the sensor which the user has touched and neighboring sensors to detect an input from the user, and does not energize the remaining sensors on the same sensor module.
