Quest 2 and Quest 3 now have an “experimental” Journey Mode to be used on airplanes.
You may add Journey Mode to your headset’s Fast settings by way of the toggle within the Experimental part of settings. Meta says it’s essential be on steady (not PTC) system software program v65 to see this and may restart your headset when you nonetheless do not. Be aware that Quest Professional is not supported, solely Quest 2 and Quest 3.
Enabling Journey Mode will make positional monitoring work on a shifting airplane. Different types of transport equivalent to trains aren’t formally supported but however shall be sooner or later sooner or later, based on Meta.
Beforehand, attempting to make use of a Quest headset on a flight would end in all digital objects and interfaces flying away in the other way when the plane modified altitude, velocity, or bearing – and when there was turbulence every little thing would violently shake. The one sensible manner to make use of a Quest on a flight was to disable positional monitoring, which additionally disables passthrough, falling again to Oculus Go type rotation-only 3DoF VR.

On sure airways Meta says the headset will robotically detect that you simply’re on a airplane and advocate turning on Journey Mode, although the corporate did not say which airways this consists of.
However Why Is A Journey Mode Wanted In The First Place?
Individuals usually suppose that markerless inside-out monitoring programs on headsets, glasses, and self-tracking controllers solely use the cameras, however this is not the case. These programs rely simply as a lot on the inertial measurement unit (IMU), a chip that incorporates a tiny accelerometer and gyroscope.
Whereas cameras sometimes run at 30Hz or 60Hz, the IMU sometimes offers updates round 1000Hz, enabling a lot decrease latency. Nevertheless, an IMU cannot truly detect absolute motion – a minimum of indirectly. The accelerometer within the IMU senses acceleration relative to gravity, and you’ll take the integral of acceleration over time to get velocity. And when you once more take the integral of these velocity values over time, you get displacement from the unique place.
This course of known as useless reckoning. From second to second, it’s how each headset and controller tracks itself, and the optical side like cameras or laser base stations are basically solely used to right for the cumulative error that outcomes from the noisiness of IMU knowledge. However in a shifting car equivalent to an airplane, the accelerometer will choose up the acceleration of the car itself, considering it is the headset itself shifting, which leads to sudden and fast positional drifting.
Apple Imaginative and prescient Professional has had a Journey Mode since launch, which we praised in our assessment – although we famous it breaks whenever you look out the window. Apparently, Meta claims its Journey Mode works even when looking a window. We plan to check Quest 3 on a airplane with Journey Mode later this month.
