Problems solved by technology

[0004] However, the smart pen must be equipped with sensors, wireless transmitters and batteries, etc., and the cost is high. When using it, it must first establish a connection with the interactive device and when the power is low, it needs to be charged or the battery needs to be replaced. The operation is cumbersome and reduces user to experience

Embodiment 1

[0024] figure 1 It is a flow chart of a method for identifying the state of a touch object provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation where the state of the touch object needs to be identified. This method can be implemented by the state recognition device of the touch object To perform, the device may be implemented by software and / or hardware. The method specifically includes the following steps:

[0025] Step 110 , emit the first infrared light and the second infrared light perpendicular to each other for touch detection.

[0026] Exemplarily, the first infrared light and the second infrared light perpendicular to each other can be emitted by infrared emitting tubes arranged in the horizontal direction and the vertical direction. For example, a circuit board frame is installed on the touch screen of a touch electronic device, and densely distributed infrared emitting tubes and infrared receiving tubes are installed on...

Abstract

Disclosed in the present invention are a state recognition method and device for a touch object. The method comprises: emitting a first infrared light and a second infrared light which are perpendicular to each other so as to perform touch detection; and confirming the orientation of a touch object according to the light intensity difference between the received first infrared light and second infrared light. The touch object comprises a transparent pen point, wherein two oppositely disposed first shading bands and two oppositely disposed second shading bands are arranged at the outer side of the transparent pen point, and the first shading bands and the second shading bands have different light transmittance. According to the method provided by the present invention, light intensity will change after the first infrared light and the second infrared light pass through the shading bands; the touch position and the orientation of the touch object may be confirmed according to detected light intensity change; state recognition of the touch object may be implemented quickly and conveniently; it is not necessary to configure the touch object in any way before state recognition is performed; and the operation efficiency is increased, and the cost is relatively low.

Description

technical field [0001] Embodiments of the present invention relate to the field of infrared touch interaction technology, and in particular, to a method and device for identifying a state of a touch object. Background technique [0002] With the development of electronic device technology, electronic devices with touch functions are popularized. Among them, human-computer interaction devices with touch functions, such as electronic whiteboards, are widely used in teaching and meeting scenarios. [0003] In the current interactive system, in order to operate the interactive device more conveniently, the smart pen is generally equipped with modules such as sensors and wireless transmitters. When in use, the smart pen is connected to the interactive device, and the wireless transmitter will The state of the smart pen detected by the sensor is sent to the interactive device, and the interactive device performs corresponding operations according to the received state of the smar...
