Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 As shown, the keyboard area 1 is projected through a laser diode, and the projected keyboard template is projected onto the surface of an adjacent interface. This module can be specifically generated by a projection component laser diode, and the light source of the diode is specially designed for efficient holographic Optics are illuminated to produce a precise QWERTY keyboard display area. It projects an invisible plane a few millimeters above the projection surface; the invisible plane 2 is projected by the low-light module. When the key operation is performed on the projected keyboard area, the low-light projection is disturbed, triggering the corresponding detection device, thus notifying The processor has a corresponding button event; the laser light reflected by the low-light sensing plane touched by the user's finger wil...

Abstract

The invention discloses an implementation method of a virtual mobile phone keyboard. The method comprises the following steps of: creating a projection keyboard template, and projecting the projection keyboard template to a surface of a certain adjacent interface, wherein the projection keyboard template can be generated by a laser diode of a projection component; illuminating a light source of the diode through a high-efficiency holographic optical element which is specially designed to generate an accurate QWERTY keyboard display region; and projecting an invisible plane at a place which is higher than a projection surface by a few millimeters. The method has the advantages that: the defects of smaller mobile phone key region of a QWERTY keyboard and difficulty in operation are overcome; a mobile phone keyboard is projected to a certain medium interface by optical projection; the operation coordinates of a projection keyboard by a user are positioned by an optical sensor; and an image is fed back to a processor and subjected to impact analysis processing to obtain an accurate key value, so that an optical projection keyboard function of a mobile phone is realized.

Description

technical field [0001] The invention relates to the field of designing electronic equipment, in particular to an implementation of a virtual mobile phone keyboard. Through optical projection, the mobile phone keyboard is projected onto a certain medium interface, and the user's coordinates of the projected keyboard are positioned by the optical sensor, and fed back to the processor for impact analysis and processing, to obtain accurate key values ​​and realize the optical projection keyboard function of the mobile phone . Background technique [0002] At this stage, full-size QWERTY keyboard mobile phones are more and more widely used, but ordinary mobile phones with a QWERTY keyboard cannot make the size very large due to the characteristics of portability. Convenience. [0003] The mobile phone projection keyboard solves the problem of portable QWERTY keyboard mobile phone and convenient input by optically projecting the keyboard template onto a certain medium interface,...
