The use of a lo-fi 3D prototype: modeling touch-based interaction in co-design
Karin Slegers · Lirias · 2008
This paper describes the use of a lo-fi 3D prototype of a Near Field Communication (NFC) service in a co-design study. The purpose of this study was to involve users in the development of a mobile payment service based on NFC. To allow users to explore and experience the touch- and movement-based interaction with the service, a wooden prototype of a mobile handset and a cardboard prototype of a cash terminal were used. Findings concerning the use of such lo-fi prototypes in user-centered design of touch-based and haptic interactions are discussed.
