These technical improvements include infrared sensors, which can be used to measure the freshness or calorie content of food. All three patented technologies can be applied to Apple's virtual reality (VR) or augmented reality (AR) devices, such as the rumored mixed reality headset similar to the visor.

Apple's three new patent applications
I. Infrared sensing technology for food detection
The first patent is an infrared sensor electronic system, which uses an infrared sensor to collect the spectrum of a target object. The system can characterize the target object by using infrared spectrum, visible camera images and/or data from other sensors alone or in combination, and may be applied to Apple's head-mounted augmented reality devices.
For example, the system can be used for food image recognition and other tasks. Through the image recognition of food, some information stored in the database can be triggered, including some characteristics of food, such as freshness, fat content, food type, sweetness and so on. In order to evaluate the maturity and calorie content of food.
2. Adaptive facial interface for head-mounted devices
The second patent describes an adaptive facial interface system for head-mounted display devices. According to the patent, the interface system can be worn on the user's head to provide good protection for the user's eyes to avoid the interference of ambient light, thus creating a comfortable environment for the user's virtual reality or mixed reality experience.
Third, eye tracking technology.
The third patent relates to eye tracking technology, which can also be applied to augmented reality and virtual reality devices. The eye tracking patent announced on Thursday is far from Apple's first. However, compared with Apple's previous eye tracking patent, the eye tracking technology of this patent has been further improved.
