Embodiment 1

[0065] Embodiment 1 of the present invention provides a system for realizing human-computer interaction, such as figure 1 As shown, it includes a mouse interaction application device 2, a mouse main body 1 and a mouse wearing device 3. The mouse main body 1 is installed on the user's arm through the mouse wearing device 3. If the user is an amputee, the mouse main body 1 is installed on the user's limb. For the device at the end of the arm muscles, if the user is a person with sound upper limbs, the mouse main body 1 is installed on the user's hand. The mouse main body 1 can be mounted on the user's arm through the mouse wearing device 3 , and the operation of the mouse can be controlled by waving the arm, thereby realizing human-computer interaction.

[0066] see figure 1 The mouse main body 1 includes a motion signal acquisition module 11, an electromyography signal acquisition module 12, a main control module 13, and a wireless data communication module 14. These modules a...

Embodiment 2

[0086] Embodiment 2 of the present invention provides a method for realizing human-computer interaction. First, the mouse main body is installed on the user's arm through the mouse wearing device, and the mouse interaction application device is installed in the terminal device; image 3 As shown, the method includes:

[0087] Step 301: When the user swings the arm, the main body of the mouse acquires the acceleration signal, and processes the acceleration signal to obtain the first processing result; according to the first processing result and the initial position of the mouse, calculate the position information and posture of the mouse through a preset algorithm information;

[0088] Preferably, in this embodiment, the acceleration signal is processed to obtain the first processing result, specifically: the acceleration signal is buffered, filtered and noise is removed to obtain the first processing result; specifically, in this embodiment, the filtering is high-pass and / or ...

Abstract

The invention discloses a method and system for realizing human-computer interaction and belongs to the field of human-computer interaction. A main mouse body is mounted on the arm of a user through a mouse wearing device. The method comprises the following steps: when the user waves the arm, obtaining an acceleration signal through the main mouse body, and processing the acceleration signal to obtain a first processing result; according to the first processing result and the initial position of a mouse, calculating with a predefined algorithm to obtain the position information and the attitude information of the mouse; collecting an electromyographic signal of the limb surface of the user through the main mouse body, processing the electromyographic signal to obtain a second processing result, and carrying out analog-digital conversion for the second processing result to obtain a digital signal; detecting the button type according to the digital signal, wherein the key is a left key or a right key; transferring the position information and the attitude information of the mouse and the button type to a mouse interactive application device on terminal equipment to analyze the operation of the user through the main mouse body. The method can improve the human-computer interaction experience of the user and does not influence the health of the user.

Description

technical field [0001] The invention relates to the field of human-computer interaction, in particular to a method and system for realizing human-computer interaction suitable for amputees. Background technique [0002] In real life, due to various reasons, there are many people with impaired upper limbs (such as amputation, broken palms, etc.). Therefore, it is of high application value to study the barrier-free information communication technology for people with impaired upper limbs. Traditional human-computer interaction equipment such as mouse keyboard, touch screen, etc. are not suitable for upper limb amputees; new human-computer interaction technologies such as voice recognition technology are obviously interfered by environmental noise, and the effect is not ideal in public places, which has certain limitations . In view of the above problems, a method for realizing human-computer interaction through mouse control is disclosed in the prior art, and its realization ...
