Although there are already computer vision systems and gloves with sensors that can detect user gestures, a team at the University of California, Berkeley, has come up with a more sci-fi alternative. It is reported that computer vision systems need to always see the user’s hand movements, but this has also led to a dispute over the protection of privacy rights, because the camera will inevitably take pictures of the user’s face. On the other hand, the scheme based on glove sensor is too cumbersome and fragile. < / P > < p > the good news is that UB Berkeley’s high-tech armband, which can detect user gestures, has more significant advantages in this regard. Specifically, the team has developed a thin-film armband with a computing chip that can be wound around a user’s forearm. < / P > < p > in the initialization phase, the user can first input the corresponding gesture action, and then the electrical sensor in the wristband will analyze the neural signal of 64 points, and use it for the pattern training of user-defined algorithm based on artificial intelligence. After < / P > < p > when the user makes the corresponding action, the system can match and judge the unique neural signal pattern. At this stage of the demonstration, we have been able to support 21 different gestures, including clenching the fist, extending the thumb, spreading the hand, and moving each finger to count. < / P > < p > more importantly, with the passage of time, the algorithm can constantly refresh and compensate the existing pattern matching accuracy. Even if the armband sensor deviates due to sweating on the arm, the system supports recognition as much as possible. < / P > < p > in addition, in order to protect the user’s privacy, all related processing work can be done in the integrated chip, and no data will be transmitted to the cloud. Looking forward to the future, the research team also hopes to use it in the control of electronic devices such as virtual reality and artificial limbs. < / P > < p > finally, the latest development of this study, led by Professor Jan rabaey, has been published in a recently published journal.
