Abstract:
A touch control virtual screen apparatus is provided. The touch control virtual screen apparatus includes a screen, an optical structure, and a detection module. The screen is adapted for emitting light. The optical structure includes at least one optical lens, and is adapted for configuring an image of a virtual screen in a space corresponding to a screen image, in accordance with the optical imaging principle. The detection module is adapted for detecting whether a user touches the image of the virtual screen, and detecting a signal corresponding to a position of the virtual screen being touched, and converting the signal into the position and a related instruction corresponding to the position. In such a way, the user is allowed to operate digital content displayed on a virtual screen in a touch control manner, without directly touching the screen.
