By pressing the button, users can execute specialized functionalities on their mobile phones, e.g. dialing phone numbers or accessing URLs. We present three usage scenarios and a proof-of-concept prototype.}, subject = {RFID}, language = {en} } @inproceedings{HemmertJoostKnoerigetal., author = {Hemmert, Fabian and Joost, Gesche and Kn{\"o}rig, Andr{\´e} and Wettach, Reto}, title = {Dynamic knobs}, series = {CHI EA '08 : CHI '08 Extended Abstracts on Human Factors in Computing Systems}, booktitle = {CHI EA '08 : CHI '08 Extended Abstracts on Human Factors in Computing Systems}, publisher = {Association for Computing Machinery}, address = {New York}, isbn = {978-1-60558-012-8}, doi = {10.1145/1358628.1358675}, pages = {2309 -- 2314}, abstract = {In this paper, we introduce the change of a mobile phone's hardware shape as a means of tactile interaction. The alteration of shape is implemented in a hardware prototype using a dynamic knob as an interaction device for the user. The knob alters the phone's shape according to different events and states, like incoming calls, new voice mail, or missed calls. Therefore, the user can explore the phone's status by touching it - ambiently, even through the pocket. Initial user testing showed that this form of tactile interaction was easy to understand and handy to interact with, also for unexperienced users.}, subject = {Haptische Feedback-Technologie}, language = {en} }
