Embodiment Construction

[0028] The low-power laser emitting device emits a low-power laser to the relevant position of the holographic image at the same moment when the person touches the relevant position, so as to give people a sense of touch. The emitted laser can either scan the touched position with a single laser or can The laser beam is focused and scanned at the touch position. The laser does not have to be a femtosecond laser, but low power is enough. The equipment is relatively large and the common laser emitting device is relatively cheap, and the size is small such as the existing laser mosquito killing device, laser processing equipment and so on. The disadvantage of a single laser beam is that on the light path of the laser from the laser emitting device to the touch location, if it shines on a person, it will also give people a feeling. The advantage of multiple laser beams is that it is the laser beam that is focused to cause human touch, and no focus will not give people a feeling, a...

Abstract

The invention relates to a holographic-projection-touchable system device. A holographic projection is formed above a holographic-projection imaging device; a dynamic detection and capturing device captures a human body position signal in real time, and sends the same to an overall control device; the overall control device outputs a control signal to a holographic-projection imaging touch scanning and analysis device at the same time; a touch scanning signal transmitting probe in the holographic-projection imaging touch scanning and analysis device works to carry out scanning on a holographic-projection area; the holographic-projection imaging touch scanning and analysis device or the dynamic detection and capturing device detects a touch on a certain position of a holographic-projectionimage, sends a touch position signal to a tactility forming device, and feeds back information to the overall control device at the same time; and the overall control device outputs a control signal to the tactility forming device; the tactility forming device emits a laser to the touch position, and thus air is ionized at the touch position by low-power laser focusing or femtosecond laser focusing for carrying out imaging and causing tactility. Positioning touches with the tactility are realized in holographic imaging technology.

Description

technical field [0001] The invention relates to a holographic projection control technology, in particular to a holographic projection touchable system device. Background technique [0002] At present, touch technology is based on screens, such as capacitive screens and resistive screens in smartphones, and there is no touch function that can be applied to imaging in the air. At present, there are patents related to laser imaging in China, but there is no touchable laser imaging. No relevant patents on touchable holographic projection have been found at home and abroad, filling the gap in this field. Contents of the invention [0003] The present invention aims at the problem that no touchable holographic projection has been found at home and abroad, and proposes a holographic projection touchable system device, which realizes tactile positioning touch in holographic imaging technology. [0004] The technical solution of the present invention is: a holographic projection...
