An touch control pen and a human-computer interaction device

Abstract

The invention relates to the technical field of touch control, and discloses an active touch control pen and a man-machine interaction device. The active touch control pen comprises a pen body, comprising an active pen core and a pen case surrounding the pen core, wherein a clamping member is arranged between the pen core and the pen case, and the pen core can do deflection movement with the clamping member as a fulcrum when the pen core is forced; a light emitter fixed on the tail of the pen cartridge, the luminous surface being arranged away from the pen cartridge; an optical signal sensingunit located on the rear side of the pen core and capable of sensing a light beam emitted from the light emitter and outputting information on the coordinates of the position where the light beam is irradiated; a micro-control unit connected with the optical signal sensing unit, and used for generating a corresponding driving signal according to the position coordinate information outputted from the optical signal sensing unit, and sending the driving signal to the touch screen through the pen core. Users can control the touch function by changing the pressing force and / or the holding postureof the active stylus, so as to meet more touch requirements and improve the application experience of the stylus.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to an active touch pen and a human-computer interaction device. Background technique [0002] With the development of touch technology, more and more mobile terminals use touch to perform human-computer interaction. The active pen is a tool often used for human-computer interaction. The current working principle of the active pen is based on the fact that when writing, the screen of the electronic device will transmit a certain pressure to the pen core, and the pressure detection device inside the active pen core will receive the pressure. After the received pressure signal is processed, it is sent to the screen of the electronic device through the conductive component and the pen core, and then coupled with the capacitance at the screen end, so that the display of the electronic device, that is, the touch display screen, presents a written image. content. However, with the develop...
