Millimeter-wave sensing, which is currently attracting attention, is a technology that uses electromagnetic waves for communication, imaging, and sensing. It can be applied in various fields such as automotive and industrial equipment, but this time, we will introduce the content of a demonstration video that realizes gesture recognition that can be used in industrial equipment with a millimeter wave sensor manufactured by Texas Instruments (hereafter TI). increase.
Gesture recognition demo using TI millimeter wave sensor

Video flow
0:00 - 0:14 Introduction
- Demonstration of unique data acquisition such as distance, speed, and angle with millimeter wave sensing
- Explain how the acquired data is actually used in a gesture recognition application
0:14 - 0:30 Explanation of Demo #1
- mmWave sensing recognizes angles and determines hand position relative to the sensor
- The demo recognizes swipe gestures and uses them as next-video triggers for video players
0:30 - 0:53 Explanation of Demo #2
- Recognize speed by millimeter wave sensing and determine the rotation angle when turning the finger
- Used for zooming up and down when viewing MRI image data
- Detection is possible even if there is a shield between the millimeter wave sensor and the recognition part
0:53 - 1:24 Introduce examples of how gesture sensing can be used
- Medical settings: When direct contact with equipment is not possible due to cleanliness in the operating room
- Factory: If you are wearing gloves or there is a lot of dust and dirt making it difficult to operate the touch panel
Three points to keep in mind
1. What can be detected by millimeter wave sensors
Non-contact detection of object distance, speed, and angle
2. Detectable even with obstructions
Materials such as stone walls, plywood, glass, and plastic can be detected even when the sensor is shielded.
3. Applications of millimeter-wave sensing
Gesture recognition (introduced in the video)
Use in environments such as medical equipment and equipment in factories where direct contact with the equipment is not possible.
TI evaluation board used in demo video
IWR1443BOOST
IWR series for industrial applications The IWR1443 is a single-chip mmWave sensor with an internal hardware accelerator, and the evaluation board is equipped with an antenna and a connection interface to a microcomputer. If you prepare this board and the online tool "mmWave Demo Visualizer" provided by TI, you can immediately check the operation, so if you are interested, please take a look.
