Magic Leap 2 Controllers Have Onboard Inside-Out Tracking

A picture shared on Twitter of the upcoming Magic Leap 2 exhibits cameras on the controllers, used for inside-out monitoring.

In January we reported on Magic Leap 2’s specs – or at the least a few of them – being shared at SPIE Photonics West 2022. However because it seems, we missed that the corporate additionally revealed that the controller itself makes use of inside-out monitoring. It wasn’t clear on the time what precisely that meant, however the picture shared this week by entrepreneur Peter Diamandis exhibits two forward-facing cameras.

Controllers in virtually all AR and VR techniques out there immediately are both tracked by the headset or depend on exterior base stations. Meta’s Quest 2 for instance tracks a sample of infrared LEDs beneath the plastic ring of its controllers, whereas Valve’s Index controllers decide their place relative to SteamVR “Lighthouse” base stations positioned within the nook of your room.

Counting on the headset for monitoring has a flaw: if the controller strikes out of view of the sensors or if any a part of your physique will get in the best way, monitoring will briefly break. This isn’t an issue for a lot of use instances, however does restrict intricate two handed interactions and situations like trying left whereas capturing proper. Utilizing exterior base stations can alleviate most of those points, however that will increase setup time and severely limits portability – and the trail from controllers to base stations can nonetheless be occluded.

Magic Leap 1 and Pico Neo 2 used magnetic monitoring. In contrast to seen mild, the magnetic subject can move by means of the human physique so occlusion isn’t a problem. However magnetic monitoring isn’t as exact as optical monitoring techniques might be, and provides important weight and value to the hardware.

Controllers with onboard cameras promise to resolve the occlusion drawback whereas sustaining excessive precision by monitoring themselves in the identical manner inside-out headsets do – utilizing a sort of algorithm referred to as Simultaneous Location And Mapping (SLAM). SLAM basically works by evaluating the acceleration (from an accelerometer) and rotation (from a gyroscope) to how excessive distinction options in your room are shifting relative to the cameras. Preliminary SLAM algorithms have been hand crafted, however most immediately use at the least some machine studying.

The potential downsides of this method are the price of a chip highly effective sufficient to run the monitoring algorithm, the discount in battery life because of the energy that chip would draw, and the necessity to have a well-lit setting with excessive distinction options resembling posters – although that limitation applies to inside-out headsets too. Some have recommended monitoring high quality could also be decreased in quick actions on account of movement blur, however this shouldn’t be any extra of a problem than monitoring fast paced LEDs – a world shutter sensor with a low publicity time ought to make this a non-issue.

Meta is seemingly additionally planning to make use of controllers with onboard inside-out monitoring in its upcoming Undertaking Cambria headset. Pictures of Quest-like controllers with cameras as a substitute of an LED ring first leaked in September, and the rings aren’t current within the official reveal trailer both.

Each Magic Leap 2 and Undertaking Cambria are slated to launch this 12 months, although neither has a selected launch window. They’re very totally different merchandise – ML2 is a clear AR headset designed for enterprise whereas Cambria is an opaque headset for VR and combined actuality – however whichever launches first would be the first AR or VR system to make use of this new method to controller monitoring.
