Abstract
A strain quantity threshold value is set in accordance with a distance from a pressure detection unit for each divided predetermined subdivision which is obtained by dividing an operation surface of a touch panel unit into a plurality of subdivisions. The minimum value of the strain quantity threshold value is set to be a value larger than a strain quantity when water or the like is attached to the operation surface of the touch panel unit.
Claims17
An electronics apparatus, comprising:
- a display configured to display content;
- a touch panel being electrostatic capacitive, overlapping the display, and having a first quadrangular shape, a side of the first quadrangular shape being located along a direction, the touch panel configured to determine a two-dimensional coordinate corresponding to an instructing object which has conductivity;
- a transparent member, overlapping the touch panel, and having a second quadrangular shape, a side of the second quadrangular shape being located along the direction;
- and
- a sensor configured to detect a bend of the transparent member at least at a first position, a second position, and a third position on the transparent member, the first position, the second position, and the third position being aligned in the direction, the second position being between the first position and the third position, wherein
- when the sensor detects the bend of the transparent member at the first position, which is larger than a first threshold value, the two-dimensional coordinate determined by the touch panel is effective,
- when the sensor detects the bend of the transparent member at the second position, which is larger than a second threshold value, the two-dimensional coordinate determined by the touch panel is effective,
- when the sensor detects the bend of the transparent member at the third position, which is larger than a third threshold value, the two-dimensional coordinate determined by the touch panel is effective,
- the second threshold value is larger than the first threshold value, and
- the second threshold value is larger than the third threshold value.
