Instruction output method and device based on wrist skin texture form change

Abstract

The invention provides an instruction output method and device based on wrist skin texture form change, and relates to the technical field of operation recognition, and the method comprises the steps:collecting a wrist skin texture form image caused by finger movement; recognizing the wrist skin texture form image, generating a recognition result, and the recognition result representing an outputinstruction corresponding to the wrist skin texture form image. Due to the fact that the fingers can make more gesture actions, the problem that instruction output in other existing modes is not richenough is solved. The texture form corresponding to each finger action is stable and is remarkably different from other actions, so that the problem that instruction output in other existing modes isnot accurate enough is solved. The method can be applied to wearable devices such as bracelets or watches, so that the problem that instruction output in other existing modes is not convenient enoughis solved.

Description

technical field [0001] The invention relates to the technical field of operation recognition, in particular to an instruction output method and device based on changes in wrist skin texture. Background technique [0002] Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR) are the hotspots of technological progress and important development directions in the future, among which devices such as smart glasses are the most important hardware devices in the above trends. [0003] At present, the popularization of smart glasses is facing several technical bottlenecks, including display capability, computing speed and command control. With the further improvement of hardware integration, the first two are expected to be solved in the short term. The remaining command control problems are A big bottleneck for smart glasses right now. [0004] The currently realized and possible command manipulation schemes are shown in the table below: [0005] command co...
