Device and method for displaying object position on near-eye second display screen

Abstract

The invention discloses a device and method for displaying the position of an object on a near-eye second display screen. The device comprises at least one light emitter, at least one light receiver, at least one optical surface and a processing unit, and the processing unit obtains position coordinates, corresponding to a first display screen, of the light emitter and the light receiver; the object contacts the optical surface to interfere the original light beam propagation path, so that the light beam received by the light receiver changes to trigger an object positioning event; and the processing unit analyzes and obtains the relative coordinate position of the object and the first display screen based on the object positioning event, and correspondingly displays the relative coordinate position on a near-eye second display screen. Compared with the prior art, the method has the advantages that the first display screen cannot be triggered by mistake while the position of the object on the first display screen is accurately positioned, the situation that a user sends a control signal unexpected by the user due to false triggering of the first display screen is avoided, and accurate and real-time man-machine interaction can be achieved when the first display screen and the display screen are separated.

Description

technical field [0001] The present invention relates to a device and method for displaying the position of an object on a second display screen near the eye. Background technique [0002] In the prior art, an intelligent electronic device such as a smart phone or a tablet computer usually uses a touch screen with a first display screen as an input device to realize human-computer interaction. For example, a smartphone, because its touch screen and display screen are integrated, when a user operates on the touch screen with a finger or a stylus and other objects, the icons displayed on the display screen can be seen, so the user's operation is intuitive and accurate. [0003] However, the touch screen and display screen in wearable devices, especially head-mounted smart devices, are often separate structures, such as VR or AR glasses connected to smartphones, because users can only see near eyes when wearing VR or AR glasses The VR or AR display screen (the second display sc...

Problems solved by technology

[0003] However, the touch screen and display screen in wearable devices, especially head-mounted smart devices, are often separate structures, such as VR or AR glasses connected to smartphones, because users can only see near-eye when wearing VR or AR glasses. The VR or AR display (second display) cannot see the smartphone screen (first display), so users cannot control the smartphone screen to achieve human-computer interaction when using VR or AR glasses

In the existing technology, there are several interactive methods such as detecting voice, eye tracking, or detecting gestures, but voice input and eye tracking have the disadvantages of being inaccurate and time-consuming, and the interactive mode of detecting gestures is easy to cause fatigue due to the need for hands to be suspended in the air and easy to misuse
