It has been one and a half years since the launch of the Nintendo New 3DS, and the new generation of Nintendo handheld is also in the process of preparation. Foreign media recently disclosed some patent details about it.

The foreign media disclosed some handheld computer patents that Nintendo had previously applied for, including more than 22 patents. Most of them are about infrared somatosensory technology of handheld computers. Through infrared sensors and cameras, you can recognize the action of the palm, measure the distance, and capture the hand image for feedback to the game. As can be seen from the patent figure, this infrared somatosensory technology can enable the machine to recognize the palm without holding additional equipment, and can be used in sports and RPG games.

This technology is similar to Intel RealSense 3D currently used by Intel on laptops, Intel RealSense 3D recognizes gestures and scenes through infrared sensors, color sensors and cameras, and can also control games through gestures. It takes a certain time from the camera's successful recognition of images to the collection of information and transmission to the game (the actual measurement of the author requires 1~2S, and you can imagine if you play a game with 1000~2000ms), which is reflected in the delay in the game, Therefore, the experience of Intel RealSense 3D is poor.

This infrared/camera body sensing technology has high requirements for data collection and image processing, and it is not easy to make a good experience.
