Embodiment Construction

[0013] Such as figure 2 As shown, the touch device 2 for virtual images floating in the air of the present invention includes at least one optical module 21 for generating virtual images floating in air, at least one first light source 22, at least one photosensitive unit 23, and a printed circuit board 24 , a processor 25 and at least one second light source 26.

[0014] The optical module 21 is combined with the printed circuit board 24; the first light source 22 and the photosensitive unit 23 are respectively placed on two opposite sides of the optical module 21; the first light source 22, the photosensitive unit 23, the processor 25 and the second light source 26 are respectively electrically connected to the printed circuit board 24.

[0015] When the optical module 21 produces a virtual image 20 floating in the air, for example, nine optical modules 21 respectively produce virtual images of numbers "1" to "9"; and the light 221 emitted by the first light source 22 pene...

Abstract

A touch device for virtual images floating in air comprises at least one optical module, at least one first light source, at least one photosensitive unit, a printed circuit board and a processor. The optical module is used for producing the virtual images floating in air and is combined with the printed circuit board. The first light source and the photosensitive unit are respectively arranged on two sides of the optical module. When the optical modules produce a virtual image floating in air and light emitted from the first light source penetrates through the virtual image, the light irradiates to the virtual image is reflected to the photosensitive unit if an article contacts with the virtual image, then the photosensitive unit outputs a photosensitive signal, the photosensitive signal is detected by the processor, so that a corresponding control signal can be sent out quickly once the virtual image is contacted.

Description

technical field [0001] The invention relates to a touch device, in particular to a touch device with a virtual image floating in the air that can be used as a keyboard. Background technique [0002] China Taiwan Publication Patent No. 200951771 discloses a device for a virtual touch screen, including a screen, an optical mechanism, and a detection module; the optical mechanism is provided with at least one optical lens, and uses the principle of optical imaging to capture the image of the screen A corresponding virtual screen image is presented in space through the optical mechanism; the detection module is used to detect whether the user touches the virtual screen image, detects and analyzes the position of the virtual screen, and converts it into a position corresponding to the touch screen and signal instructions The user can operate the digital content displayed on the virtual screen in a touch mode, so as to achieve the function of actually operating the screen without ...
