Event Recognition for Meaningful Human-Computer Interaction in a Smart Environment: Mobilephone

Diffusion Tensor Magnetic Resonance Imaging (DTI) is a rathernew technique that allows in vivo imaging of the brain nervousstructure. The DTI data is a 3D second-order positive semi-definite tensor field. DTI analysis and visualization is a chal-lenging field due to the lack of standards and high-dimensionalityof the data. This project focused on 1) implementation of abase DTI tool compatible with the tensor field standard (STAC)as proposed by the SIMILAR NoE WP10 group, 2) develop-ing haptic interfaces for effective visualization and investiga-tion of aforementioned 3D tensor fields. Both goals have beenachieved, yet their integration could not be completed with theEnterface2007 workshop. Howeever, the know-how built duringthe workshop and the codes generated are invaluable resourcesfor developing the final application. VAVlab (Boğaziçi Univer-sity, EE Dept., İstanbul, Turkey) is currently working on the in-tegration of these components into a complete application.
