DOI: 10.5220/0005938900240032 In Proceedings of the 3rd International Conference on Physiological Computing Systems (PhyCS 2016), pages 24-32 ISBN: 978-989-758-197-7http://hdl.handle.net/10400.13/4600The 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.engLarge display nterfaceFloor projectionElderlyNatural user interfaceKinect.Faculdade de Ciências Exatas e da Engenhariaconference object10.5220/0005938900240032
