On March 8, SpaceX investor Peter Diamandis MD (Peter Diamandis) published a latest photo of Magic Leap 2 on Twitter, and said: This AR headset color expression is quite excellent, and it is more optimized than the previous generation in terms of field of view and volume. In addition, the photo shows a close-up side of the Magic Leap 2 handle, which appears to be equipped with multiple cameras in addition to the trigger, or for Inside-Out positioning.
According to Qingting Network, the current mainstream 6DoF headset positioning scheme on the market is mainly divided into Two kinds of Outlook-In and Inside-Out, of which Outlook-In needs to use an external base station, the typical representative is SteamVR, and Inside-Out is to add a positioning camera outside the headset, represented by the Meta Quest all-in-one machine. Usually, AR headsets are not equipped with 6DoF handles, but use 3DoF electromagnetic tracking handles (such as Magic Leap 1), or use gesture tracking to operate.
In contrast, the Magic Leap 2 uses a special gamepad positioning method, directly on the controller built into the camera, almost no XR headset manufacturers have commercialized this solution before. Judging from the picture of the Quest Pro (code name Cambria) controller exposed last year, Meta seems to be exploring the design of the camera equipped with the controller.

Theoretically, compared with the positioning handle with the headset camera, the built-in camera on the handle to locate the headset helps to expand the tracking range of the handle and avoid the tracking interruption after the handle leaves the headset to locate the camera field of view (the handle can be located wherever it moves). In addition, gesture tracking can be optimized, controller tracking delay can be reduced, and the camera can be transferred from the headset to the handle, which can further reduce the size of the headset and eliminate the tracking ring design commonly used by 6DoF.
The disadvantage is that when two or more headsets appear in the tracking range, the tracking drift problem may occur. At the same time, it is expected that this will also increase the overall cost and power consumption of the headset.
