A human-computer interaction method, device, interactive whiteboard, and storage medium

Abstract

This invention provides a human-computer interaction method, device, interactive tablet, and storage medium. The method includes: driving an infrared transmitter to emit infrared signals on the surface of a display screen, driving an infrared receiver to receive the infrared signals on the surface of the display screen, determining that the intensity of a portion of the infrared signal in the current frame decreases relative to a reference range, determining that the intensity of a portion of the infrared signal in the current frame increases relative to the reference range, responding to the current frame infrared signal, and performing a touch operation. This embodiment distinguishes whether a touch object touches the surface of the display screen and whether a touch operation is responded to based on the rise and fall of the infrared signal, adapting to the needs of business scenarios and thus improving the performance of touch operation in the business scenario. In writing scenarios, it can solve the problem of zero-height writing.
