Here is a cool belt that lets you interact with head-worn displays more easily. It has a touch surface that goes around your hip, allowing you to access the information and applications you need quickly. Here is what the developers had to say about it:
In a qualitative user study with 14 participants we found out that for short interactions (2-4 seconds), most of the surface area is considered as appropriate input space, while for longer interactions (up to 10 seconds), the front areas above the trouser pockets are preferred.
