A formative model for hand input devices in virtual environments or haptic manipulation

A condensed version of a general and formative user model for a hand input device in human-computer interaction is presented which arises from a single subject case study developing guidelines for a postural interface in a virtual environment. There was no model available in human-computer interaction, or other fields related or otherwise, thus the impetus for formulating a model. The user model though simplistic amalgamates several factors, offering a foundation for knowledge on hand input devices for haptic operation and in virtual environments.
