Problems solved by technology

[0003] The screen of mobile devices is designed to be relatively small for portability, but on the screen interface, the virtual keyboard alone takes up more than one-third or even one-half of the size, and because of the size of the screen, the distance between the keys and the The size of the buttons greatly limits our input feel. The premise of the existing projection keyboards on the market is the need for independent hardware external devices, but they all have the following

Abstract

The invention discloses a laser projection input scheme embedded into mobile terminal equipment, the mobile terminal equipment is provided with a laser transmitter and an infrared laser, and the lasertransmitter projects a virtual keyboard to a desktop;wherein the infrared laser emits infrared rays for detecting laser, and the infrared laser receives a signal that the infrared rays are intercepted and triggers an interruption program in the infrared laser; starting a camera for snapshot; Processing the image captured by the camera; obtaining a key position where a finger is parked on the virtual keyboard on the plane image, obtaining an offset position, and calculating coordinate values of x and y corresponding to the finger on the desktop according to a triangular distance measurement method; The method comprises the following steps: finding a key position corresponding to a virtual keyboard, packaging the key position into a system universal input event data packet, sending the system universal input event data packet to an application layer for use, ending identification, modifying a projection keyboard, and directly embedding the projection keyboard into mobile terminal equipment to meet the portability requirement of the mobile terminal equipment.

Description

【Technical field】 [0001] The invention relates to a laser projection input scheme embedded in mobile terminal equipment, in particular to a laser projection input scheme embedded in mobile terminal equipment in a text input mode. 【Background technique】 [0002] As mobile terminal technology becomes more and more mature, mobile terminal equipment includes but is not limited to mobile phones, pads, etc., and other mobile devices without physical keyboards. Although there are more and more varieties, the homogenization situation is also becoming more and more serious. And some design issues with the terminal itself remain. [0003] The screen of mobile devices is designed to be relatively small for portability, but on the screen interface, the virtual keyboard alone takes up more than one-third or even one-half of the size, and because of the size of the screen, the distance between the keys and the The size of the buttons greatly limits our input feel. The premise of the exis...
