3D touch screen, 3D numeric keyboard manufacturing method and touch interaction method

Abstract

The invention discloses a 3D touch screen, a 3D numeric keyboard manufacturing method and a touch interaction method. The 3D touch screen is arranged on a rear cover plate of an intelligent terminal and comprises a 3D numeric keyboard, a touch unit and a display unit, and the 3D numeric keyboard is chemically etched or carved on the rear cover plate. The 3D numeric keyboard manufacturing method comprises the following steps: manufacturing a 3D glass rear cover plate of the intelligent terminal; arranging a display window and a touch area on the 3D glass rear cover plate; engraving or chemically etching a 3D numeric keyboard in the touch area. The touch interaction method comprises: a user knowing key information by touching the 3D numeric keyboard; the user pressing the plurality of keys,transmitting the interaction information to the intelligent terminal and displaying the related information through the display window. By implementing the method, the problem that a blind person or aperson with poor eyesight cannot effectively interact with the intelligent terminal in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of mobile phone touch control, in particular to a 3D touch screen and method that can be used by people with poor eyesight. Background technique [0002] What the touch screen brings to us is not only the convenient operation that you can get at a touch. All we need to do is to press the screen lightly with our fingers. At the same time, we can also achieve functions that are impossible without a touch screen. Graffiti as you like, just like holding a paintbrush. An action that requires a few button presses on a keyboard might just be a swipe on a touchscreen. Just the light touch and touch of a finger can transform our physical touch into digital codes. [0003] Since the touch screen can replace the buttons, the burden brought by the keyboard can be discarded, and the screen can be extended to the entire panel to achieve a greater balance between the body and the screen size. For most users, a larger sc...

AI Technical Summary

Problems solved by technology

[0005] The problem existing in the existing smart terminal is: there is no real operating feel, and it cannot provide a strong feedback response like a real keyboard. Interaction, the interactive operation of the flat touch area of ​​the smart terminal consumes a lot of power

[0006] In view of the above problems, a 3D touch screen and method are proposed. By opening a display window on the back cover of the smart terminal and etching or engraving a 3D numeric keypad, the functions of the smart terminal can be retained, and a real operating feel can be obtained. , which solves the problem in the prior art that the blind or poorly sighted cannot effectively interact with the smart terminal
