Direct Touch-based Mobile Interaction with Dynamic Displays

An inherent obstacle in current mobile applications is the limited output capabilities of mobile phones. This paper describes a solution to this limitation which is based on a combination of a public display and Near Field Communication (NFC) technology. The public display (represented by a projection in the developed prototype) is augmented with a matrix of NFC tags whereby each tag is analogous to a touchable pixel on the display. A corresponding NFC mobile phone behaves as a 'smart'; stylus for interaction with the

display. According to the user's interaction, dynamic feedback is projected onto the matrix of tags. A map-based tourist guide prototype was implemented which successfully demonstrates the feasibility of the concept. A user study analysed the usability of the interaction technique and elicited ideas for further development.
