Touch simulation device and touch simulation method

Abstract

The invention discloses a touch simulation device, which is arranged above a device to be touched. The touch simulation device comprises emitting electrodes, receiving electrodes and a signal processing circuit, wherein the emitting electrodes and the receiving electrodes are mutually crosswise arranged and are electrically insulated from each other; the signal processing circuit receives a touch control instruction; the receiving electrodes receive a pulse synchronization signal of a driving circuit in the device to be touched through electric field induction; the signal processing circuit processes the pulse synchronization signal into a synchronous electric field signal applied to the emitting electrodes according to the touch control instruction; and the synchronous electric field signal enables an induction circuit in the device to be touched to generate electric field change for determining that touch behaviors happen. The invention also discloses a touch simulation method. In the absence of physical motion, the touch simulation device and the touch simulation method realize the finger touch simulation of touch-sensitive devices including a touch screen, support the simulation of actions including multi-point touch, dragging, click, double click and the like, and realize the operation of the touch-sensitive devices including the touch screen and the like under the condition that a space above the touch screen is insufficient or a user can not conveniently operate with hands.

Description

Technical field [0001] The invention relates to a touch simulation device and a touch simulation method. Background technique [0002] Mobile smart devices such as smart phones have now become indispensable personal items in people's work and life due to their convenience and rich application functions. As the hardware specifications of smartphones become more powerful, their computing and storage capabilities have approached or surpassed personal computers. Many applications previously running on personal computer systems have been able to run on smartphones. It can be said that to a certain extent, smartphones can Replace personal computer. Due to the requirement of portability, the size of the smart phone screen is usually designed to be a smaller size, such as less than 5 inches, which limits the application of the smart phone in some occasions that require a larger display size. [0003] At present, smart phones usually have HDMI video output, which can project the content d...
