Patent ID: 8749517

Claim:
A touch sensing device with a touch hold function, comprising: an interaction surface, in particular a touch panel, with a touch location system for determining a touch position based on an acoustic signal, an acoustic isolating means being elastically compressive and dielectric provided on one surface of the interaction surface; a first conductive electrode provided between the interaction surface and the isolating means; a second conductive electrode, the first conductive electrode and the second conductive electrode sandwiching the isolating means; a means for determining the capacitance between the first conductive electrode and the second conductive electrode; and a capacitance processing means configured to determine a touch hold and/or touch release based on a change of capacitance between the first conductive electrode and the second conductive electrode, determine a hold action upon the detection of a touch by the touch location system, provide information regarding a hold position on the basis of a plurality of measured capacitances, and and carry out a comparison of the touch position determined by the touch location system and the hold position.
