Design and Distribution of Physical and Mobile Interfaces for Multi-Tag Interaction Diploma Thesis, Ludwig-Maximilians-Universität München, 2009 (bib) |
Physical mobile interaction is the interaction between a mobile device and a physical object. Using enabling technologies like bluetooth, numeric identifiers, visual codes or near-field communication (NFC), this kind of interaction is made possible. Up to now, as depicted in the related work section, the focus in this area is based on single-tag interaction meaning only one single tag is used in an application, usually to start an application or a service. Consequently only very few approaches rise above this and use, reuse and combine more than one tag. This interaction style is called multi-tag interaction. Aside from concrete examples, a general categorisation for multi-tag interaction is given stating four categories: Navigation, Selection, Combination of Information and Mapping. Conducting three user studies, three of these categories (Navigation, Selection and Combination of Information) are evaluated considering their general usability and the distribution of information on the mobile interface as well as the physical interface. Using different prototypes, consisting of a Java ME based mobile application supporting NFC and a tag-enhanced poster, quantitative data, like execution time, attention shifts and errors, is collected as well as qualitative data based on user feedback. |
