Method for detecting a touch-and-hold touch event and corresponding device

摘要

The invention relates to a method for determining a touch-and-hold touch event on a touch sensitive interaction surface of a touch sensing device comprising the steps of: a) determining a touch location of the touch event based on vibrations, such as bending waves, propagating through the interaction surface and b) determining whether the touch event comprises a hold touch event based on a sensed airborne signal. By integrating the acoustic signal it thus becomes possible to decide whether a touch or a touch-and-hold touch event occurred on the interaction surface. The invention furthermore relates to a device configured to carry out the inventive method. The invention further relates to an electronic device comprising a first element with a first surface and a second element with a second surface, the first and second surface forming an angle ± with respect to each other, a means for emitting an airborne signal provided on or in the first element at least one means for sensing airborne signals provided on or in the first element, and a means for analyzing sensed airborne signals wherein the means for analyzing sensed airborne signals is configured to determine a position of an object relative to the second surface based on sensed airborne signals. The invention furthermore relates to a corresponding method.
