These techniques have been used within the requirements gathering phase of a
project developing a video camera based ‘fall’ monitor and detector for older people
in their homes [16]. It was reported that the dramatized scenarios provided an
excellent way of setting a shared context for discussions between potential users and
designers, focused discussion on specific scenarios of likely system usage, and were
very effective in provoking discussion of relevant details because elderly users could
imagine themselves within the scenarios shown in the video.
