Hi Juan,

Beware of fixed device positioning - this will effect the way the device is
used. Consider a traditional candybar handset - the user normally holds the
device and presses buttons with the same hand (single handed interaction).
If you fix this device to a table, then users will find it more natural to
"type" by poking the buttons with their forefingers. A problem of ecological
validity.

In the past I've used a mobile testing kit put together by
http://www.tracksys.co.uk/ (UK company) - composed of off-the-shelf
components nicely packed into a flight case. It was a perfectly good set up,
but if I was setting up a mobile lab now, I'd probably use the new version
of Morae since it supports multiple cameras. (and the VNC set up you refer
to, with a bit of tinkering).

There are lots of different possible camera configurations you can consider.
Try googling "Helmet camera" or "bullet camera" for some possibilities...

Hope that helps

Harry
