Antonio Krüger and I represented the technology perspective with example from the domain of ubiquitous computing. My talk "ubiquitous computing in adulthood and old age" is a literature review in pictures of selected ubicomp systems targeted as an introduction to non-CS people to the domain. The discussions were really inspiring. In one talk Prof. Jim-Chern Chiou from National Chiao Tung Univeristy in Taiwan (the brain research lab) presented interesting dry electrodes that can be used for EEG – but also for other applications where one need electrodes.
Antonio reported an interesting experiment on the navigation/walking performance of people. The basic message is: if you are old and you can hold on to something while walking you gain cognitive resource – if you are young this effect is not given – has quite interesting impliciations . Antonio worked on more in this domain, see .
Over lunch we discussed some ideas related to persuasive technologies and Ulman Lindenberg hinted me some relevant authors (Bargh, Gollwitzer) and I found an interesting manual on subliminal prime on the web.
