React/Interact aims to develop advanced
user-interface techniques for IPT systems. Evaluation of the utility of
these interfaces will address both individual usability and "group
usability". Group usability refers to the
ability of co-located and distributed collaborators to comprehend the
intentions and actions of the user. The original objectives of the project
were three-fold:
1.
To develop a stable, flexible interaction infrastructure based upon
a mature Collaborative Virtual Environment (CVE) toolkit
(See Phase 0)
2.
To design and implement a toolkit of specialised interaction
techniques to support the single-user, co-located group and distributed
group within an Immersive Projection Technology (IPT) system
(see Figure 1 above) (See Phases 1,2,3).
3.
To carry out a series of three evaluative experiments in order to
determine the most appropriate interaction metaphors for each context of
use of an IPT (See Phases 1,2,3).
Because
of forces external to the project we were able to achieve Objective 1
earlier than expected. We thus were able to add a further objective:
1a.
To develop a stable, flexible interaction infrastructure based upon a
mature CVE toolkit 1b. To develop an experimental platform based upon Open
Source software. (See Phase 0).
