    Driver Activity Recognition from Sitting Postures
    (Mensch & Computer 2007 Workshopband, 2007) Riener, Andreas; Ferscha, Alois
    Automatically adapting vehicle settings due to activities of the driver has crucial impact to safety in road traffic, intelligent driver assistance and vehicle control systems as well as driving comfort. Distraction continues to increase by reason of technology growth (classical office- and home electronics like entertainment and navigation systems, televisions, Email and internet-clients, multimedia player, on-board computers, multi-function dashboards, game consoles, etc. are now built-in in cars). We study the possibilities of identifying typical drivers activities inside the car by evaluating pressure patterns collected from force sensor arrays, invisibly and unobtrusively integrated into the fabric of the driver seat and backrest. Along this key task, algorithms are developed for sitting posture recognition and empirical studies are performed to assess the reliability of activity recognition from sitting postures.

    Presence sensing billboards
    (Informatik 2009 – Im Focus das Leben, 2009) Wally, Bernhard; Ferscha, Alois; Lenger, Markus
    The Out-of-Home (OOH) media markets currently rely on a plethora of methods and technologies for measuring their potential or real success. From nation-wide interviews over statistical analyses to device based mobility records, each of the OOH markets (in different regions or countries) has chosen its own mixture of measurement efforts in order to provide more or less clear numbers to their clients. In this contribution, we are presenting the Presence Scanner, a new and inexpensive tech- nological approach to detecting the presence of people in front of OOH media sites. Based on an array of ultra sonic range finders and equipped with wireless communication capabilities, the Presence Scanner is on its way to resemble a flexible and scalable solution to plug and play activity sensing in (at least) indoor scenarios.

    Tokenized interaction architecture
    (Informatik 2009 – Im Focus das Leben, 2009) Dong, Boxian; Wally, Bernhard; Ferscha, Alois
    Out-of-Home (OOH) advertising is currently advancing into a new era: "pervasive advertising" is one of the buzz words describing a soft change from the traditional push-only media to an interactive and bi-directional advertisement experience. While ambient media solutions try to conquer each and every piece of potential advertisement surfaces by various sorts of print media, another trend can be observed as well: OOH advertising is becoming smarter (at least from an electronics point of view). Digital signage products, SMS, Bluetooth interaction in city lights and talking billboards that react on the feedback of motion sensors—pervasive advertising is on its way. However, the development of a pervasive advertisement platform is beyond the scope of any single engineering or art discipline; instead it is a multidisciplinary effort including electronic engineering, computer science, art, cognitive psychology and even social sciences. Therefore, we introduce a tokenized interaction architecture; a foundation on top of low level issues that simplifies sub sequent implementation efforts by addressing interaction, context awareness and hardware heterogeneity, so to release designers of pervasive advertising campaigns from computer related challenges.
