Summary of VAYYAR’S SINGLE-CHIP PLATFORM PERFORMS GESTURE DETECTION
4D Imaging radar offers high-resolution, wide field-of-view scanning for in-cabin safety and gesture detection. Vayyar’s single-chip platform integrates 48 transceiving antennas using RoC to produce real-time 3D frames (4D when motion is included), enabling applications like child presence detection, seat belt reminders, and gesture recognition by analyzing 5 cm pixels across multiple antennas to determine direction, distance, and changing gestures.
Parts used in theVayyar single-chip 4D Imaging platform:
- Single-chip 4D Imaging radar platform
- 48 transceiving antennas (integrated on single package)
- RoC antenna integration technology
- Software for in-cabin safety applications (child presence detection, seat belt reminders, gesture detection)
- Real-time imaging processing for 3D frame generation
- Pixel mapping with 5 cm spatial resolution
4D Imaging using radar technology provides good resolution and field of view for scanning applications. Vayyar’s single-chip platform is a good example, as it integrates multiple antennas using RoC for improved 4D Imaging.
The multifunctional single-sensor platform fulfills the Euro NCAP safety requirements using its 4D Imaging feature. The chip comes with 48 transceiving antennas on a single package, hence reducing the complexity and cost of the device. The 4D Imaging chip is compatible with various software for creating in-cabin safety applications. This includes child presence detection, seat belt reminders, and gesture detection.
The gesture detection by using the 4D Imaging chip follows the conventional method of radar imaging, with some additional techniques. The radiowaves cover a certain volume of space by transmission through multiple antennas for calculating direction and distances. The usage of multiple antennas can create a 3D structure. Additionally, the chip also enables analysis of the neighboring pixels by receiving the data on all receiving antennas. This creates real-time imaging of continuous 3D frames, hence allowing 4D Imaging.
Talking more about gesture detection, the real-time 3D frames are in motion if the person moves from the original position to a different position. The 4D Imaging chip is capable of scanning the data using 5 cm large pixels in the space. The system then matches the pattern of these pixels with the general gesture patterns. As, the device supports real-time imaging, so it can detect the change in gestures on a real-time basis as well. This is how gesture detection happens using the 4D Imaging technique.
