Problems solved by technology

For handwriting input, the wearer can learn faster as if using a physical keyboard, but there are a series of problems such as it is not convenient to carry and use, and the limbs are prone to fatigue.
At present, speech recognition technology has obvious technical advantages, but speech recognition also has inherent defects. In addition to its own recognition accuracy, accurate speech recognition in noisy environments is also a technical problem.
Moreover, voice input is an open input method, and the operation content is easily known by people around, so voice recognition has security risks when inputting sensitive information; even for non-sensitive information, few people will use it in public Voice input technology, because talking to yourself in public can be somewhat embarrassing
[0003] Sensor information conversion input based on vision, etc. is a new input method with the gradual maturity of image processing and sensor technology. Its working principle is to use the information collected by the camera or other sensors to analyze and process it through a specific algorithm and then convert it. For events such as corresponding button input, its main advantage is to get rid of the limitation of button space, and the function customization is flexible, which is very consistent with the input requirements in the embedded environment, but the big problem currently existing is how to combine the collected information with button events exact correspondence
