A BELIEVABLE FEEDBACK SYSTEM WHIT A QUASI-TANGIBLE TABLETOP INTERFACE

摘要

PURPOSE: A haptic U table is provided to supply effective active haptic feedback according to dragging which contact time is long or an input which a contact surface is large by consisting a vibration motor in a screen of a tabletop interface. CONSTITUTION: A touch screen converts an analog signal according to a touch input into a digital touch signal. A vibration motor(200) generates a vibration. A generating control unit(300) generates a vibration control signal controlling vibration strength and time of the vibration motor by receiving the touch signal form the touch screen through a serial communication. A motor control chip(400) controls and drives the vibration motor according the vibration controls signal.
