VR/AR/MR equipment is knocking on the door of the metaverse, these key technologies deserve attention!

3D Time of Flight (ToF) is a method of capturing depth information over short distances using scanner-less Light Detection and Ranging (LIDAR) technology. In AR and VR headsets, ToF systems use cameras to collect depth information and then process this data to simulate another dimension of reality for the user.

ADI provides a variety of ToF products and solutions, such as high-resolution CMOS imaging chips , depth computing and processing , laser drivers , power management , and related development tools and software/firmware.

Wearable vital sign monitoring (VSM) uses a non-invasive device to provide biosensory feedback to the XR system. The monitoring device can be worn on the wrist, forehead, chest or ear. Vital sign data can be used to adjust immersive experiences in real-time based on the user's reactions and emotions. It can be as simple as mapping emotions onto an avatar's face, or it can be a safety feature such as changing the behavior in a different way when an elevated heart rate is detected. way to adjust.

Analog Devices provides optical sensors , highly integrated analog front ends (AFEs) , bioelectrical AFEs , motion sensors , bioimpedance engines , low-power MCUs and motion sensors , power management solutions , and high-precision temperature sensors . In addition, ADI's wearable VSM solutions are optimized for low-power, space-constrained applications and leverage optimized sensor and connectivity technologies to ensure product quality and reliability.

Movie surround sound, especially near-field surround sound, can meet the high-quality 3D audio experience required by VR and AR head-mounted devices , making users feel more realistic. But to achieve this, the challenges inherent in the extreme space constraints of headsets require designers to overcome the limitations of common audio amplifier solutions.

The ADI MAX98360 Class D amplifier solves these challenges with high efficiency and low standby power in a small package that does not require programming using plug-and-play technology.

If we want to better interact with AR, VR and XR devices, the system must be able to understand and interpret our intentions, and designers need to improve the accuracy of embedded sensors and minimize latency. Whether through voice, gestures, head movement or eye tracking, high-quality sensors may be the key to a fully immersive, natural experience.

ADI provides a series of solutions in this field, such as our Pure Voice technology, which can remove background noise and make speech clear; gesture tracking solutions have high resolution and can understand the user's movements. Our future Solutions can utilize ultrasound, ToF, electromyography (EMG) or electroencephalography (EEG). Other HMI opportunities include capacitive-to-digital converters (CDCs) for creating touch interfaces on devices, capacitive-to-digital converters (CDCs) for heads Tracking Inertial Measurement Unit (IMU) and additional sensors.
