Abstract

The invention provides an operation method of a projection keyboard of an intelligent terminal. The operation method comprises the following steps that the projection keyboard is in communication connection with an intelligent wearable device; the projection keyboard projects a keyboard image at a target position, and an infrared horizontal optical network is horizontally projected at the positionof the keyboard image; when a first human body finger falls into a first letter range, the projection keyboard captures a reflected light spot image of the first human body finger to infrared horizontal light; the position information of the first human body finger is acquired and mapped to a keyboard layout; the intelligent wearable device captures a knocking action of the first human body finger, and a key instruction is fed back to the projection keyboard; the key instruction is received by the projection keyboard, a keyboard key event is generated, and an electric signal is fed back to the intelligent wearable device; the intelligent wearable device receives the electric signal and feeds back rebound stimulation to the first human body finger. According to the method, the intelligentwearable device is used for further monitoring the knocking action of the human body finger, and the effectiveness of information input is ensured.

Description

technical field [0001] The invention relates to the technical field of spare parts of intelligent terminals, in particular to a projection keyboard of an intelligent terminal and an operation method of the projection keyboard. Background technique [0002] With the development and progress of science and technology, smart terminals are constantly innovating. Currently, smart terminals are widely used in people's work, study and life because of their versatility and portability. As the instruction and data input device of the intelligent terminal, the keyboard can realize the input of English letters, numbers, punctuation marks, etc. into the computer, so as to issue commands and input data to the computer. Since the development of the keyboard, it has continuously improved and innovated with the needs of the market and users. For example, with the continuous requirement of the portability of smart terminals, a virtual projection keyboard came into being. As a new input met...
