Our small team are prototyping an engineering mixed reality app in Unreal 5.4 (hoping to move to 5.5 soon). The app is designed for HMD, but we are prototyping with a handheld Android tablet as we consider whether a traditional XR headset or XR glasses would be a better hardware choice. Some of the wearable devices under consideration are quite expensive, so we are trying to avoid acquiring multiple devices of which we would only use one or two.
The UI, for now, is just a temporary scaffold so we can validate whether the core engineering functionality of the app is viable. This validation will also give us insights that can guide the choice of wearable device(s) as we enter production app development.
Since the production app will use OpenXR rather than ARCore, it would be useful to prototype in OpenXR even if by doing so we would lose some of the features of the handheld mode. I’ve not found anything in the documentation about doing this, but since OpenXR supports mixed reality as well as VR, “in theory” it should be possible to run OpenXR on a tablet.
Is this something that can be done but typically isn’t, or is it simply not feasible at all? Any insights from those who might have tried this would be appreciated. Thanks!
