> i found that publishing papers and visiting conferences is a great way to explore and discuss interests further than just researching on your own. during the last month i have written (and even published) some papers by myself and in cooperation with other researchers from my university (thanks a lot! it was a pleasure).

Do you feel what you see? multimodal perception in virtual reality


abstract: This paper discusses how different physically existing materials can be mapped on virtual textures in mixed reality environments by carrying out an explorative user study (n=101). For physical materials-in form of 3d trackable and moveable cubes-acrylic, wood and aluminum have been used. The virtual textures convey the impression of ceramic, fabric, glass, leather, paper, wood, acrylic, quartz, granite and aluminum. The study reveals which virtual textures match well with the different virtual textures and which do not match at all.

Keywords: haptics, mixed reality, perception, virtual reality

improving pedestrians safety through proactive street lighting


abstract: Although digital revolution has pervaded almost every part of daily life, cities remained seemingly analogue and furthermore inhabitants are mostly excluded from the digital layer. By using established infrastructure of city lights we try to ensure that our concept can be implemented in the most simple and realistic way: Our intention is to project content on pavement by replacing timeworn light bulbs with a projector linked with an intelligent sensor array. With this approach we expect to increase social interaction within open spaces by creating a more engaging way through the city and reduce the use of distracting and separating mobile devices. Considering the increasing wish for safety as well as present accident statistics, society faces the necessity to support the needs of their weakest traffic participants – pedestrians. As for today we propose several applications to support pupils having a safe way to school and back, to highlight danger zones to prevent accidents and to guide large crowds in an increasingly complex city. We want to provide a more economical, safer and smarter way to lighten up the way through future cities.

self-presentation offline & online [german]


introduction (short): Who am i? - no later then with the wide spread of the participatory internet, this question can no longer be answered with a homogeneous response: identities fragment, offline identities become online users. this process of transformation creates inter alia partial, pseudo- and substitutional identities that first of all, presents the user within his brave new [online] world which later can become a part of their overall identity. how self-sufficient are these two identity constructs? to what extent is one able draw conclusions about their offline-identity from these new avatars?

urban hacking in virtual realities [german]


„The ultimate display would, of course, be a room within which the computer can control the existence of matter. A chair displayed in such a room would be good enough to sit in. Handcuffs displayed in such a room would be confining, and a bullet displayed in such a room would be fatal. With appropriate pro-gramming such a display could literally be the Wonderland into which Alice walked.“

[Sutherland, I., 1965. The Ultimate Display. pp. 506-508.]
