Testing Room-scale VR

I tested the HTC Vive headset recently which opens up a whole new realm of possibilities. This obviously means more ways in which issues can manifest.

The HTC Vive is geared towards a Room-scale VR experience. The user will be generally stood up during use. This means more things need to be taken into account by the teams developing and testing these applications, which are mostly games at this point.

Now although Oculus Rift have stated that their headset is capable of Room-scale VR it is geared towards a sat-down experience. Understanding these distinct experiences is necessary before we can start to think about how we are to test them.

Sat down experiences take out the issue of a user bumping into their environment. It would still be possible in some particularly confined setups, but these are edge cases IMO (still not to be fully dismissed). Sat down experiences also take out the worry of becoming entangled in the headset cable and take out the possibility of a user tripping over.

Whilst all the above is true, sat down experiences also lose an element of immersion. Putting the HTC Vive headset on and experiencing the environment for the first time is an incredible feeling. Something as simple as kneeling down to pick an object up feels special. The controllers for the Vive also add to the experience, but they also provide another area for things to go wrong.

Applications being developed and tested for Room-scale VR have to take into account the variety of spaces people will have. Some developers have stated that you don’t need a huge amount of room to experience Room-scale VR. It is said you need enough room to stand up and stretch out in all directions. This video from the makers of Hover Junkers explains:

Whilst the makers of Hover Junkers have been very attentive to room size issues and the range of rooms users will have; we cannot assume everyone else will. We have to be aware that room size issues will come into play. Using boxes/crates to quickly change the test space you have is going to be necessary. It’s all well and good having the great test space you’ve setup in the office but how will that translate to the student dorm room?

Thinking about testing Room-scale VR leads me to think that we need a new heuristic to aid this testing.
