Gesture locking method and device of bionic hand, terminal and storage medium

The invention discloses a gesture locking method and device for a bionic hand, a terminal and a storage medium, and the method comprises the steps: obtaining a first electromyographic signal, and determining a first gesture corresponding to the first electromyographic signal; a second electromyographic signal is obtained, a second gesture corresponding to the second electromyographic signal is determined, the first electromyographic signal and the second electromyographic signal are both generated based on the brain movement intention of a wearer of the bionic hand, and the second electromyographic signal is an electromyographic signal collected after the bionic hand executes the first gesture; whether the first gesture is a locking gesture or not is judged, and when the first gesture is the locking gesture, the bionic hand is controlled to continuously execute the second gesture until the preset duration is reached. The problems that in the prior art, a wearer of the bionic hand is not focused, electromyographic signals fluctuate, and then gestures with long operation time have errors are solved.

What the filing appears to be about, read by published rules from its title, abstract and classification codes (G06F3/014, G06F3/015, G06F3/017). The claims define what a patent protects, and they are not read here.

Interface and electrodes

Everything downstream works with what the contacts pick up. Their number, size and distance from the neurons set the ceiling on the signal. The problem behind it: more contacts, closer to neurons, that still record after years in tissue that reacts to them.

Why the layer matters to the field, not a judgement of this filing. A patent family shows that protection was sought. It does not show that the technology was built, is used in a product, or works in people. The whole stack

Dates as the offices published them. Office records are in the offices' own words and are a selection: refusals, lapses and withdrawals, and records that name an owner. Each concerns one member of the family, not the family as a whole, and another member in the same office may stand. Whether a patent is in force today is not assessed.
