Range: exploring proxemics in collaborative whiteboard interaction

This is a relatively short work in progress paper that introduces the idea of using proximity to a display as an implicit interaction technique in whiteboards.

Using relative location to display as an implicit interaction technique is heating up.

Interactive public ambient displays: transitioning from implicit to explicit, public to personal, interaction with multiple users


A very well written paper with a good literature overview of public display work. The authors build an interaction framework for public displays with 4 phases: Ambient Display, Implicit Interaction, Subtle Interaction, and Personal Interaction. They also provide a series of design principles for building public ambient displays: Calm Aesthetics, Comprehension, Notification, Short-Duration Fluid Interaction, Immediate Usability, Shared Use, Combining Public and Personal Information, and Privacy.

They present a prototype ambient display system where gestures are used to interact with the display, both as a method of allowing users to transition from different states in the interaction framework, and "personally interacting with the display". They performed a simple evaluation of their display, and found people were able to use it.

In Proceedings of the 17th Annual ACM Symposium on User interface Software and Technology (Santa Fe, NM, USA, October 24 - 27, 2004). UIST '04. ACM, New York, NY, 137-146. DOI= http://doi.acm.org/10.1145/1029632.1029656

The main take-aways of this paper are the design guidelines and the 4 phase interaction framework for public displays: Ambient Display, Implicit Interaction, Subtle Interaction, and Personal Interaction.

Situated interaction with ambient information: Facilitating awareness and communication in ubiquitous work environments

Situated interaction with ambient information: Facilitating awareness and communication in ubiquitous work environments

This article primarily describes some first steps in creating ambient displays to facilitate awareness in work environments. Although the authors do not evaluate their work they do talk about some of the issues one encounters when building displays. Describing 3 zones of interaction:

* Ambient Zone
* Notification Zone
* Interactive Zone

They describe a process of the display "borrowing a display", the idea that other devices or people might want to borrow room on a display.

All in all this paper isn't all that great, other authors talk about zones of interaction -- though it is interesting to think about the difference between the information that can be transmitted using LEDs and large displays. The 'Bandwidth' of the display medium, if you will.


There is a much better follow up article to this at:

But, the take-aways are about the same.
