Abstract

The present invention relates to a MYO-based text input system and method. By using the MYO wristband, a text input system with natural interaction, wide use and higher efficiency is designed and manufactured, including the MYO wristband, the muscle in the wristband The use of electrical sensors and attitude sensors, the design of user interface and virtual keyboard in the system and the sensor data processing method and machine learning algorithm in the system; Send it to the server; the server processes the obtained data and extracts relevant features, and then obtains the category of the action through the random forest model; after the user interface receives the action category signal from the server, it makes a corresponding action ; The design and color matching of the user interface. In the present invention, the collected myoelectric signal and the signal of the posture sensor are fused and analyzed to improve the accuracy of gesture classification.

Description

technical field [0001] The invention relates to the field of intelligent human-computer interaction, specifically an innovative text input method, which can meet the needs of normal people and forearm amputee patients to use computers. Background technique [0002] There are many problems in the traditional keyboard input mode. For example, the user must have healthy hands, and the hand must be placed on the keyboard to complete the input, which is a limitation for many usage scenarios, and the interaction is extremely unnatural. However, although the existing new text input methods, such as voice input, have a natural interactive mode, they are easily affected by accents and noisy environments, and their use is often limited. Therefore, we need to develop a text input system that interacts naturally and is not limited by the environment and the user's physical condition. In recent years, the principle and application of myoelectricity have attracted much attention in the ...
