They went wireless
The Wireless AR Smart Viewer also got a more powerful chipset and a system that uses Wi-Fi 6/6E and Bluetooth instead of a USB-C cable.
This can potentially lead to very short battery life. However, Qualcomm says consumer versions may be designed differently.
Like its predecessor, the new glasses connect to a phone or computer and immerse the wearer in mixed reality with full head and hand tracking.
Qualcomm has kept the previous 1920 x 1080 resolution and 90Hz refresh rate in the displays, but narrowed the field of view slightly.
