The present invention discloses a touch simulation device provided above a touch-sensitive device. The touch simulation device comprises: transmitting electrodes and receiving electrodes arranged in an overlapping manner and electrically insulated from each other, and a signal processing circuit for receiving a touch control instruction. The receiving electrodes receive a pulse synchronization signal of a drive circuit in the touch-sensitive device via the electric field induction. The signal processing circuit processes the pulse synchronization signal to a synchronization electric field signal applied to the transmitting electrodes according to the touch control instruction. The synchronization electric field signal enables an induction circuit in the touch-sensitive device to generate an electric field change for determining the occurrence of a touch action. The present invention further discloses a touch simulation method. The present invention realizes finger touch simulation on a touch-sensitive device such as a touch screen without physical motions and supports the simulation of actions including multi-point touch, drag, tap, and double-tap, thus enabling operations on the touch-sensitive device such as the touch screen when a space above the touch screen is not allowed for operation or in a situation inconvenient for a human hand to operate.
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 become indispensable personal belongings in people's work and life due to their convenience and rich application functions. With the increasingly powerful hardware specifications of smartphones, their computing and storage capabilities have approached or surpassed that of personal computers. Many applications that previously ran on personal computer systems have been able to run completely on smartphones. To a certain extent, smartphones can Replacement of personal computers. Due to the requirement for portability, the size of the smartphone screen is usually designed to be smaller, for example, less than 5 inches, which limits the application of the smartphone in some occasions that require a larger display size. [0003] At present, smart phones usually have HDMI video output, which can proje...
