Date of Defense 2004-06-22 Availability unrestricted Abstract Evaluation is the key to effective interface design. It becomes even more important when theinterfaces are for cutting edge technology, in application areas that are new and with little prior
design knowledge. Knowing how to evaluate new interfaces can decrease development effort and
increase the returns on resources spent on formative evaluation. The problem is that there are few,
if any, readily available evaluation tools for these new interfaces.
This work focuses on the creation and testing of a new set of heuristics that are tailored to the
large screen information exhibit (LSIE) system class. This new set is created through a structured
process that relies upon critical parameters associated with the notification systems design space.
By inspecting example systems, performing claims analysis, categorizing claims, extracting design
knowledge, and finally synthesizing heuristics; we have created a usable set of heuristics that is
better equipped for supporting formative evaluation.
Contributions of this work include: a structured heuristic creation process based on critical
parameters, a new set of heuristics tailored to the LSIE system class, reusable design knowledge in
the form of claims and high level design issues, and a new usability evaluation method comparison
test. These contributions result from the creation of the heuristics and two studies that illustrate the
usability and utility of the new heuristics.
