We are presenting PanoVC — a mobile telepresence system based on continuously updated panoramic images. We are showing that the experience of telepresence, i.e. the sense of "being there together" at a distant location can be achieved with standard state-of-the-art mobile phones. Because mobile phones are always on hand users can share their environments with others in a pervasive way. Our...
We present a method for recognizing a video that is playing on a TV screen by sampling the ambient light sensor of a user's smartphone. This improves situation awareness in pervasive systems because the phone can determine what the user is currently watching on TV. Our method works even if the phone has no direct line of sight to the TV screen, since ambient light reflected from walls is sufficient...
In this paper, we propose MT-Diet, a smartphone-based automated diet monitoring system that interfaces a thermal camera with a smartphone and identifies types of food consumed at the click of a button. The system uses thermal maps of a food plate to increase accuracy of segmentation and extraction of food parts, and combines thermal and visual images to improve accuracy in the detection of cooked...
