This paper presents an analysis, implementation and evaluation of the physical mobile interaction techniques touching, pointing and scanning. Based on this we have formulated guidelines that show in which context which interaction technique is preferred by the user. Our main goal was to identify typical situations and scenarios in which the different(More)

Mobile devices are more and more used for mobile interactions with things, places and people in the real world. However, so far no studies have discussed which interaction techniques are preferred by users in different contexts. This paper presents an experimental comparison of four different physical mobile interaction techniques: touching, pointing,(More)
To reach a good user-friendliness, knowledge about user requirements is crucial in the development process of a product. The sooner the knowledge is achieved via user evaluations, the more money and time can be saved. In this paper we investigate an approach called hybrid simulation for the early stages evaluation of mobile applications where real mobile(More)
There is currently a lot of research going on in the field of mobile interaction with the real world. So far, the environment where the mobile phone is used is mainly perceived as an unpleasant and disturbing factor. Therefore it has rarely been used as a part of the interaction. But on the other hand there is a huge potential for new kinds of the(More)
In this paper we present results of a user study that we conducted with 21 subjects to investigate whether initial user trust is accompanied by unconscious bodily responses which enable more objective measurements than user reports. In particular, we recorded the user's eye gaze and heart rate to evaluate whether users respond differently when interacting(More)
