PVA conclusions

In order for the `personal visual assistant' to be useful, it will need to be small, lightweight, tetherless, and unobtrusive. Many of the design issues have already been dealt with, but much remains to be done. For example, a sufficiently powerful body-worn computer with eye tracking capability will be necessary before the PVA will be of widespread use to the visually challenged.
