10.5 Additional Interaction Mechanisms

This chapter has covered three families of interaction mechanisms: locomotion, manipulation, and social. These families emerged from decades of research and development, but do not completely cover every kind of interaction. Many systems demand a custom interaction mechanism be constructed that does not fall into the three families. Furthermore, with the widespread current use of low-cost VR systems, we expect that new families will emerge. A few examples of other interaction mechanisms and associated challenges are presented here.
