Web-research on suggestions by the industries
There is plenty of information on how to design for VR available online. Some of this information is more valuable than others. In a systematic research process I identified a series of resources. Using a clustering method I structured these resources according to their relevance and bundled different design suggestions to a series of design principles. In order to allow easy back-tracing of the principles, two indipendent infographs arose (see below).
Expert interviews and evaluation
Altogether five experts from the fields VR research, VR development, and interaction design were interviewed about VR matters and their stance on VR design principles. An evaluation procedure helped give the conducted principles further structure by assigning each a different level of importance.
