Abstract(s)
The recent development of affordable full body tracking sensors has made this technology accessible to
millions of users and gives the opportunity to develop new natural user interfaces. In this paper we focused
on developing 2 natural user interfaces that could easily be used by an elderly population for interaction with
a floor projection display. One interface uses feet positions to control a cursor and feet distance to activate
interaction. In the second interface, the cursor is controlled by ray casting the forearm into the projection and
interaction is activated by hand pose. The interfaces were tested by 19 elderly participants in a point-and-click
and a drag-and-drop task using a between-subjects experimental design. The usability and perceived workload
for each interface was assessed as well as performance indicators. Results show a clear preference by the
participants for the feet controlled interface and also marginal better performance for this method.
