Reto Wetach visits our lab… and looking for someone with expertise in pain

Reto Wettach was in Essen so we took the opportunity to get together to flash out some ideas for a proposal – it is related to pain – in a positive sense. There is interesting and scary previous work, see [1] & [2]. For the proposal we still look for someone not from the UK and not from Germany – who has an expertise and interest in medical devices (sensors and actuators) and someone who has experience in pain and perception of pain (e.g. from the medical domain). Please let me know if you know someone who may fit the profile …

Before really getting to this we had a good discussion on the usefulness of the concept of tangible interaction – obviously we see the advantages clearly – but nevertheless it seem in many ways hard to proof. The argument for tangible UIs as manipulators and controls is very clear and can be shown but looking at tangible objects as carriers for data it becomes more difficult. Looking a physical money the tangible features are clear and one can argue for the benefit of tangible qualities (e.g. I like Reto’s statement „the current crisis would not have happened if people would have had to move money physically“) – but also the limitations are there and modern world with only tangible money would be unimaginable.

Taking the example of money (coins and bills) two requirements for tangible objects that embody information become clear:

  • The semantic of the information carried by the object has to be universally accepted
  • Means for processing (e.g. reading) the tangible objects have to be ubiquitously available

There is an interesting and early paper that looks into transporting information in physical form [3]. The idea is simple: data can be assigned to/associated with any object and can be retrieved from this object. The implementation is interesting, too – the passage mechanism uses the weight of an object as ID.
