Our Posters at Ubicomp 2008

In the poster session we showed 3 ideas of ongoing work from our lab and got some interesting comments and had good discussions. 

Ali presented initial findings from our experiments with multi-tactile output on a mobile phone [1]. He created a prototype with 6 vibration motors that can be individually controlled. In the studies we looked at what locations of the vibration elements and what patters can be spotted by the user. In short it seems that putting the vibration motors in the corners works best.

Florian showed ideas on counting page impressions on public advertising screens we sketched out with Antonio's Group in Münster [2]. The basic idea is to use sensors to get an idea of the number of people passing by. To calibrate such a system (as the sensor observations are only incomplete) we propose to use existing ways of counting people (e.g. access gates to public transport) and extrapolate based on this information.

I presented Dagmar's poster on initial work on providing information on the fuel economy in an engaging way to the user [3]. In a focus group study we observed that people are more aware of the price of a journey when using public transport than when using a car. For the car they know well the price per liter but have to calculate the price for a typical trip (e.g. to work). We suggest ideas where one can compete with others (e.g. from the social network) in saving energy on a specific route.
