Response to [Situated information… (Chameleon)] by Fitzmaurice


Fitzmaurice believed information should be present and accessed concurrently and collocatedly with real world objects or environments related to that information.


This interaction concept was demonstrated in the Chameleon prototype – a palmtop computer aware of its surrounding and adjusted the view to displayed information relevant to that physical context.


* Our goal is to go a step further by grounding and situating the information in a physical context to provide additional understanding of the organization of the space and to improve user orientation;

* The key idea is that the physical object anchors the information, provides a logical means of partitioning and organizing the associated information space, and serves as a retrieval cue for users.

* Good way of writing enabling technology: Although the prototype palmtop device is currently tethered by cords (…), it provides a rich environment for testing new situations, applications, and user interactions in a technology configuration we anticipate will be available in a few years in a highly portable form.

* Good way of writing a summary: Ubiquitous computing requires a qualitative change in the way we think and interact with computers. Instead of viewing and manipulating a computerized world through a large stationary computer and display, we want to shift to a new model in which we carry around a very small palmtop computer that acts as our personal display onto information spaces. These displays are aware of their surroundings and change depending on the situation in which they are immersed.


* The office example: distributed interactions. Currently there is a dichotomy: computer world and real world. To add another one, consider the world in our mind. The fact is, we do not always interact with real objects. Much of our conversation refers to non-real objects, e.g., objects elsewhere, objects in the past. People communicate about them by reaching a common ground of perceiving such objects in their minds, as if they can see, hear, smell, taste and touch them. The interaction is pretty much internalized, similar to reading a science fiction story. Let’s call it mind world. Can interaction happen in this world? Can interaction bridge, now, the three worlds?
