- Embedding information where and when it is useful
- Embedding information in a most unobtrusive way
- Providing information in a way that there is no interaction required
Looking at an active computer display (OK it was broken) that circled the luggage belt (it is designed to list the names of people who should contact the information desk) and a fixed display on a suitcase I was reminded of this paper. With this set-up people become aware of the information – without really making an effort. With active displays becoming more ubiquitous I expect more innovation in this domain. We currently work on some ideas related to situated and embedded displays for advertising – if we find funding we push further… the ideas are there.
