Abstract

A contactless input device communicates with a transparent touch panel and a display screen. The device includes a storage device for storing a plurality of instructions. A processor for loading the instruction to perform the steps of: when a user inputs a touch gesture at a touch position on the touch panel, obtaining a position of a human eye, a first distance between the human eye and the touchpanel, a second distance between the display screen and the touch panel, a type of the touch gesture and a touch position of the touch gesture on the touch panel from the touch panel; Determining aninput position of the touch gesture on the display screen, wherein the input position is located at an intersection point of an extension line of a line connecting the eye position and the touch position and the display screen; Generating a gesture instruction corresponding to the type of the touch gesture; The gesture command and the input position are sent to the display screen, thereby triggering the display screen to execute the gesture command at the input position.

Description

technical field [0001] The invention relates to the field of display screen input, in particular to a non-contact input device and method, and a display capable of non-contact input. Background technique [0002] At present, more and more occasions require the use of giant screens, suspended screens and projection screens. It is generally difficult for the user to directly touch this type of screen, so it is also difficult to perform gesture operations on this type of screen through touch input. Contents of the invention [0003] In view of this, it is necessary to provide a non-contact input device and method that can solve the above problems. [0004] In addition, it is also necessary to provide a display capable of non-contact input. [0005] The present invention provides a non-contact input device capable of communicating with a transparent touch panel and a display screen. The non-contact input device includes: a storage device for storing multiple instructions; an...
