Device adapted for emulating tactile contacts on a capacitive screen

摘要

The invention relates to a device comprising a capacitive keyboard (KB) constituted of a plurality of keys (KY), each key comprising an active electrode (AEL) and an active ground plane (AGP), a microcontroller (MC) connected to said keyboard through the active electrode and the active ground plane. Said microcontroller is adapted for managing said keyboard in a reverse manner for emulating a sequence of tactile contacts on a capacitive screen when the device is placed on said capacitive screen.
