Shading input method

Abstract

The invention relates to a shading input method. The invention provides an input method applied to intelligent equipment which is suitable for advertising or providing voice service for the public inpublic gathering places, the input method is an isolated input method which can be used by the public, and the equipment under the public use condition reliably realizes man-machine interaction through the method.

Description

technical field [0001] The invention relates to a device installed in a public gathering place for advertising, publicizing and providing voice and video services to the public, especially a device for providing the public with intelligent voice services such as background music, tour guide, medical guide, and shopping guide. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, more and more advertising screens, publicity and education devices, and various smart devices (equipment) that provide voice and video services to the public appear in public gathering places, such as smart background music playback, Audio guide device, etc. In order to improve the benefits and effects of these devices, it is often necessary to allow the public to participate in the management of these devices, or to understand the specific needs of the public, which requires the device to have the necessary interaction with t...

Problems solved by technology

Now the most commonly used input method is button input, but button input has the problem that the button structure is easy to be abrasive and damaged, especially in the case of public use, there may be rough operation problems, and the service life of the button is shorter. In addition, it is required to be rainproof and sealed outdoors Under the circumstances, the button structure will destroy the sealing; the emerging voice input method often has a lot of background noise interference in public gathering places, especially when the device itself is playing music, the reliability of voice input will be greatly reduced; now the electronic touch screen is used There are also many, but the technical cost is relatively high, especially under the conditions of outdoor public use, the equipment itself requires dustproof and rainproof, the structure is sealed and strong, the protective shell (shielding cover) is often thick, and the sensitivity of touch will also have problems

Now, light control is also a frequently used input method, but the current light control uses artificially emitted auxiliary light (usually infrared light) as the signal source, which is inconvenient to use on devices used by the public. On the one hand, infrared The emitter itself is a tool that is easily damaged. In addition, there are management problems in making the infrared emitter public.
