Abstract
A hover touch device with sensory feedback includes: a capacitive touch panel, and a touch driver chip which drives the capacitive touch panel to generate and output a sensing information; based on the sensing information, an embedded system determines whether a conducting object is inside an effective region. The embedded system calculates spatial coordinates of the conductive object, and outputs the spatial coordinates to a graphical user interface, so that the graphical user interface displays a position feedback image on a display device based on the spatial coordinates of the conductive object as a visual feedback. After the embedded system recognizes a hovering gesture event, a speaker generates a hovering gesture event feedback sound as an auditory feedback. The embedded system also makes the speaker broadcast a warning sound when a user's finger contacts the capacitive touch panel.
