FULL BODY TRACKING USING FUSION DEPTH SENSING - A simplified explanation of the abstract
This abstract first appeared for US patent application 17838139 titled 'FULL BODY TRACKING USING FUSION DEPTH SENSING
Simplified Explanation
Techniques in this patent application involve using radar sensor devices on a wearable device to detect, measure, and track the location of objects. The radar sensors generate and evaluate radar signals from the wearable device and its surroundings. Objects within the field of view that reflect radar signals will produce return signals with specific characteristics.
- Radar sensors on a wearable device detect and track the location of objects.
- Radar signals are generated, captured, and evaluated by the sensors.
- Objects within the field of view reflect radar signals and produce return signals.
- Return signals have characteristic time of arrival, angle of arrival, and frequency shift.
- Processing the return signals allows determination of distance, direction, and identification of objects.
- Object information can be further resolved by correlating with measurements from cameras or inertial measurement units.
Potential applications of this technology:
- Augmented reality: Radar sensors on a wearable device can enhance augmented reality experiences by detecting and tracking objects in the user's environment.
- Navigation and obstacle avoidance: The technology can be used to provide real-time information about the location and movement of objects, aiding navigation and avoiding obstacles.
- Security and surveillance: Radar sensors on wearable devices can be used for security and surveillance purposes, detecting and tracking objects in the vicinity.
Problems solved by this technology:
- Limited visibility: Radar sensors can detect objects even in low visibility conditions such as darkness, fog, or smoke.
- Real-time tracking: The technology allows for real-time tracking of objects, providing up-to-date information on their location and movement.
- Object identification: By analyzing radar characteristics, the technology can identify objects, aiding in their classification and tracking.
Benefits of this technology:
- Enhanced situational awareness: Radar sensors on wearable devices provide users with a better understanding of their surroundings, improving safety and decision-making.
- Versatility: Radar sensors can be used in various applications and environments, making them adaptable to different use cases.
- Complementary to other sensors: By combining radar data with data from cameras or inertial measurement units, more accurate and comprehensive object information can be obtained.
Original Abstract Submitted
Techniques disclosed herein may be utilized to detect, measure, and/or track the location of objects via radar sensor devices that are affixed to a wearable device. Each of the radar sensors (e.g., MIMIC radar sensor) generates, captures, and evaluates radar signals associated with the wearable device (e.g., HMD) and the surrounding environment. Objects located within the field of view with sufficient reflectivity will result in radar return signals each with a characteristic time of arrival (TOA), angle of arrival (AOA), and frequency shift (Doppler shift). The sensed return signals can be processed to determine distance and direction, as well as identification of the objects based on radar characteristics of the object (e.g., radar back-scatter or cross-section pattern). Object information, including position and identification, may be further resolved based on correlation with measurements from one or more of the digital cameras or inertial measurement units.
