Problems solved by technology
At present, smart devices have the function of projecting the operation interface on the arm or other skin for touch operation. This method can replace the traditional display screen with the projection screen; but in this solution, the projection screen is usually projected on the On the surface of the skin, since the projected screen is often relatively small and difficult to control, people with strong hair are not suitable for this function because their skin is hairy and uneven; Suitable for displaying projection screens, also not suitable for this function

The invention discloses a projection touch screen control method and device which are used for fusing voice and touch multimode input modes and optimizing a touch operation. The method comprises the steps that a touch command from a projection touch screen is received, and according to position information of a touch position of the projection touch screen, a key at the touch position and word description matched with the key are magnified and displayed automatically; a voice command corresponding to the word description is received, and whether the degree of confidence of the voice command reaches a preset threshold value or not is detected; when the degree of confidence of the voice command reaches the preset threshold value, the touch operation of the key matched with the work description is executed according to the voice command. According to the projection touch screen control method and device, the voice operation function is added on the basis of the touch operation of the projection touch screen, after the voice and touch multimode input modes are fused, misoperation possibly brought by voice recognition is avoided, and the touch experience is optimized to the maximum extent; operation is convenient, and the projection touch screen control method and device are suitable for more people.
Description
Technical field [0001] The present invention relates to the field of Internet technology, in particular to a method and device for controlling a projection touch screen. Background technique [0002] With the development of science and technology, projection technology has developed more and more rapidly, and the increasing rise of smart devices, especially the use of wearable smart devices, makes people's smart control life mode better development. At present, the function of projecting the operation interface on the arm or other skin for touch operation has appeared in smart devices. This method can replace the traditional display screen with the projection screen; but in this solution, the projection screen is usually projected on On the skin surface, because the projection screen is often relatively small and difficult to control, people with strong hair are not suitable for this function due to the hairy and uneven skin at the projection site; while users with dark skin are ...
