METHODS AND APPARATUSES FOR LATENCY REDUCTION IN GESTURE RECOGNITION USING MMWAVE RADAR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18174602 titled 'METHODS AND APPARATUSES FOR LATENCY REDUCTION IN GESTURE RECOGNITION USING MMWAVE RADAR
Simplified Explanation
The method involves processing radar data to detect gestures using a sliding input data window.
- Radar frames in the data window contain selected features and time-velocity or time-angle data.
- Binary predictions are received for each radar frame to indicate if a gesture has ended.
- An early stop (ES) checker is triggered if a gesture end is predicted to determine if ES conditions are met.
- ES conditions include noise frames and valid activity conditions being satisfied.
- A gesture classifier is triggered to predict the type of gesture if ES conditions are met.
Potential Applications
- Gesture recognition systems
- Human-computer interaction technology
- Security systems
Problems Solved
- Accurate detection of gestures in radar data
- Efficient processing of radar frames
- Reduction of false positives in gesture recognition
Benefits
- Improved gesture recognition accuracy
- Real-time gesture detection
- Enhanced user experience in interactive systems
Original Abstract Submitted
A method includes obtaining a stream of radar data into a sliding input data window composed of recent radar frames from the stream. Each radar frame within the data window includes features selected from a predefined feature set and at least one of time-velocity data or time angle data. The method includes, for each radar frame within the data window, receiving a binary prediction indicating whether the radar frame includes a gesture end. The method includes in response to the binary prediction indicating that the radar frame includes the gesture end, triggering an early stop (ES) checker to determine whether an ES condition is satisfied. Determining whether the ES condition is satisfied comprises determining whether a noise frames condition and a valid activity condition are satisfied. The method includes in response to a determination that the ES condition is satisfied, triggering a gesture classifier to predict a gesture type.
