Impressions from Pervasive 2008

Using electrodes to detect eye movement and to detect reading [1] – relates to Heiko’s work but uses different sensing techniques. If the system can really be implemented in goggles this would be a great technologies for eye gestures as suggested in [2].

Utilizing infrastructures that are in place for activity sensing – the example is a heating/air condition/ventilation system [3]. I wondered and put forward the question how well this would work in active mode – where you actively create an airflow (using the already installed system) to detect the state of an environment.

Further interesting ideas:

• Communicate while you sleep? Air pillow communication… Vivien loves the idea [4].


• A camera with additional sensors [5] – really interesting! We had in Munich a student project that looked at something similar [6]


• A cool vision video of the future is SROOM – everything becomes a digital counterpart. Communicates the idea of ubicomp in a great and fun way [7] – not sure if the video is online – it is on the conference DVD.
