SYSTEM AND METHOD FOR CONVERTING INPUT SIGNAL FROM TOUCH SENSITIVE INPUT DEVICE INTO VARIABL TACTILE EFFECT

摘要

In the present invention, in a system for converting an input signal from a touch sensing input device into a variable tactile effect, a touch sensing unit 10 is configured to detect the occurrence of a signal of a touch input, wherein the touch sensing unit 10 is a user A touch sensing sensor 11 for sensing a touch input of a finger or a pen of a user, and a touch input signal sensing unit 12 for checking the type of a touch input using the capacitance and pressure value sensed by the touch sensing sensor 11 ), a finger touch input unit 13 receiving a touch input signal by determining that the touch input is a touch input by a user's finger by the touch input signal detecting unit 12, and the touch input signal detecting unit 12 By determining that the touch input is a touch input by a touch pen, the pen touch input unit 14 receiving the touch input signal, and the strength and weakness of the touch input input by the finger touch input unit 13 and the pen touch input unit 14 , A touch input management unit 15 that manages change values of touch inputs such as coordinate movement, area increase and decrease, and a touch input signal input to the touch input management unit 15 to select valid touch inputs, which is a sensible frequency band of 20~ A controller 20 that converts within 450 Hz to generate a vibration frequency, a driving circuit 40 that controls the generated vibration frequency, and a tactile feedback by receiving the vibration frequency of the controller 20 through the driving circuit 40 It is composed of an electroactive transducer (50) that provides a touch panel to detect changes in contact area or pressure when inputting a touch panel, and provide real-time tactile feedback suitable for signal input to the user, and within the haptic frequency band when providing tactile feedback. As the vibration signal is generated, there is an effect of providing a touch sensation capable of feeling simultaneous and realism when a signal is input from the touch panel.
