qualitative experience data gathering
Using the lo-fidelity prototype you constructed in the last deliverable (or a revised version, depending on the feedback you got from me), gather data about how uses experience your concept and initial design. Let the scenarios key your inquiry.
Focus on the important details, such as:
- Flows of essential information, expression, and control;
- The affordances that enable the user to affect the system, and how the system and the participants respond;
- How to make state visible audible, and tactile;
- Social aspects of the experience, and how your system affects them.
A suggested approach is to carry out the process described in [3].
Rehearse on each other before you bring in your
subject/friends. Realize that lo-fi prototypes can be buggy!
Work to identify and fix bugs in advance.
Assign the suggested roles -- such as
greeter, computer, observer -- to
members in your group.
A creative and constructive approach is to think of yourself as
conducting a workshop [1, 2], in which participants explore important
aspects of the experience of your installation, but without the technololgy.
Boil it down to the essentails. Perform a "debriefing" at the end [3].
You may create whatever variations on this process you like, to the
extent that you are very clear in your sense of what you're doing. Ask
me (by email or in person) if you're unsure.
Your write-up could go 3 conference pages. One section should be data,
not the raw data, but in an organized form. Focus on the relevant stuff.
Then provide a section of analysis, followed by lessons learned, and
next steps.
system architecture
From this evaluation, you should have a clear idea about how you will build your system. Create a clear functional block diagram, which indicates, essential modules and flows of control. Document important message passing structuresreferences
