Embodiment Construction

[0021] The basic idea of ​​the solution provided by the embodiment of the present invention is to simply identify the area with specified color information in the image obtained by the camera, and determine the information input to the terminal based on the change information of the area, thereby solving the problem of the prior art. The input method adopted has a higher requirement on the terminal and a relatively large demand on hardware resources, or the problem that part of the displayed content of the touch screen will be blocked when the finger touches the touch screen.

[0022] First, an embodiment of the present invention provides an information input method based on camera information. The specific flowchart of the method is as follows figure 1 shown, including the following steps:

[0023] Step 11, the terminal recognizes the area with specified color information from the image obtained by the camera, wherein the camera can be set on the terminal, or it can be indepe...

Abstract

The invention discloses an information input method and terminal based on a camera, aiming to provide an input way which is free of shielding the screen of the terminal and low in resource consumption. The method comprises the following steps of: identifying, by the terminal, an area having specified color information in an image obtained by the camera; determining the change information of the area; and determining the information to be input into the terminal according to the change information.

Description

technical field [0001] The invention relates to the field of communication technologies, in particular to a camera-based information input method and a terminal. Background technique [0002] With the continuous development of the terminal, the function of the terminal becomes more and more powerful, and the way of human-computer interaction becomes more and more convenient, natural and friendly. At present, many terminals support multiple user input methods such as keyboard input, touch screen input, and voice input. When users input, they are most accustomed to using fingers to complete input operations. Fingers are the most direct and effective human-computer interaction tool. In the prior art, in addition to the traditional keyboard-based finger input method, there are the following two types of finger input methods: [0003] Method 1: Camera-based method, that is, using computer vision technology to track and recognize finger movement trajectory, and realize input by ...
