Simple SummaryContent extracted from patent full text and abstract with AI.

This patent discloses a system and method for precise, contactless detection and analysis of hand features (such as position, speed, movement, or shape) using a combination of a radar system (as the primary module) and a 3D imaging sensor (as the assisting module). The data from both sensors is intelligently fused by a controller to improve measurement accuracy, enable real-time tracking, and allow the generation of virtual hand representations for uses such as gesture recognition, movement analysis, and hand-object interactions.

Use CasesContent extracted from patent full text and abstract with AI.

• Medical diagnostics and rehabilitation for monitoring and assessing hand function over time
• Sports, fitness, and ergonomics for analyzing hand movements and performance
• Human-computer interaction through gesture recognition for touchless device control
• Virtual reality (VR) and augmented reality (AR) systems for realistic hand tracking and avatar generation
• Industrial or workplace safety monitoring to prevent repetitive strain or track proper hand usage
• Robotics and teleoperation, enabling precise control based on human hand tracking
• Gaming and entertainment for immersive, markerless hand control integration

BenefitsContent extracted from patent full text and abstract with AI.

• High precision and resolution in tracking hand movements and features
• Contactless and markerless operation enhances user comfort and convenience
• Real-time analysis enables responsive and interactive applications
• Robustness against common limitations of purely optical or radar-based systems (e.g., occlusions, limited accuracy)
• Compatibility with transparent or semi-transparent objects, allowing hand-object interactions to be observed without interference
• Versatile sensor fusion enables use in both controlled and unconstrained environments
• Facilitates the creation of digital hand models for avatars or simulation purposes

Patent Abstract

The invention relates to a system for ascertaining a feature of a hand, said system comprising a primary module, an assisting module, and a controller. The primary module comprises a radar system with at least one transmitting antenna and at least one receiving antenna, and the assisting module comprises a three-dimensionally imaging sensor, wherein the primary and the assisting module are designed to carry out a respective detection of the feature, generate measurement data with respect to the feature, communicate with the controller which is designed for this purpose, be actuated by the controller which is designed for this purpose, and transmit the measurement data to the controller which is designed for this purpose. The controller has means which are designed to actuate the primary module such that the measurement data generated by the assisting module is taken into consideration, and the controller has means which are designed to ascertain the feature of the hand from the totality or from a part of the totality of the generated measurement data.
