Mobile phones have traditionally been utilized for personal and individual use. In this paper we explore shared co-located interactions with mobile phones. We introduce a phone-based application that supports ad hoc brainstorming sessions. The prototype allows a workgroup to create, edit and view virtual mind-map notes on any table surface. The prototype encourages people to use the devices interchangeably and thus engage in social interactions. Evaluations show that participants were able to easily create mind maps and that the prototype supports different strategies in mind-map creation.

Traditional augmented reality UI views are restricted to the visible surroundings around the user. In this paper we present a concept that enables viewing and accessing geospatial data from all around the Earth, by pointing with the device towards a physical location. We describe a prototype of the concept and share the results of the first user experience study conducted with the prototype. We also discuss our future research directions.

We present the user experience study results of a novel interaction concept that enables viewing and accessing geospatial data from all around the Earth, by pointing with a mobile device directly towards any physical location. We explain the relationship of this concept to traditional augmented reality and map based user interfaces, and we describe a prototype of the concept. In the evaluation we found that whole body interaction is a good way to browse geospatial content. The need for real-time information arises when using the concept. Reliable and detailed information is expected. Examining the Earth became interesting with the prototype. We also discuss the challenges faced in the prototype and suggest ways to tackle them.
