<P>PROBLEM TO BE SOLVED: To provide a touch sensing device having high accuracy in touch sensing. <P>SOLUTION: The touch sensing device includes: a capacitive sensor for detecting capacitance variation and converting the capacitance variation into a first electrical signal; a piezoelectric sensor for detecting physical shock and converting the physical shock into a second electrical signal; and a display unit; wherein the information displayed on the display unit is controlled by the first electrical signal and the second electrical signal. The thickness and area of the capacitive sensor are designed to be optimal such that the touch sensing device has highly reliable sensibility. In addition to the capacitive sensor, the touch sensing device further includes a piezoelectric sensor for detecting physical shock, providing an alternate sensing technique for the users to choose. <P>COPYRIGHT: (C)2013,JPO&INPIT |
