Intelligent Advisor for Human-Computer Interface Design (IAHCID).
Completed a feasibility study of IAHCID concepts to provide the HCI
design team with rapid accessibility to the enormous array of existing
design data, filtered and tailored for the design project at hand.
As an HCI is being designed from components, IAHCID advises the designer
on all aspects of the design issues by incorporating knowledge of
basic human-computer interaction principles and the results of many
years of research on the application of those principles. The advisor
is capable of learning, so that relevant advice can be provided during
an iterative HCI design process, where the results of usability testing
are incorporated in the design. It also considers user-specified constraints
on the HCI design, such as the availability of a speech synthesis
and recognition capabilities. IACID assists the HCI designer in task
analysis and selection and layout of specific HCI elements, interactively
leading the user through the logical steps of the design process,
ensuring that all of the required information elements are represented,
and supporting the designers' creative and evaluative activities with
new and powerful tools (Naval surface Warfare Center)
Expert system to support rotorcraft pilot-vehicle interface design.
Developed an expert system consisting of: a database summarizing information
requirements for mission management; a rule base for the recommendation
of display parameters based on information attributes; and an inference
engine to drive the display recommendation process. The system is
designed to organize collections of analytical information, document
the growth of rules for information display, and manage application
of the rules to the database. (NASA-Ames Research Center)
Cockpit display formats for high-performance aircraft. Designed
a digital terrain management and topographic display system to be
integrated into the AFTI/F-16 aircraft cockpit. Identified current
deficiencies in the performance of 23 critical cockpit functions such
as analysis of target data, selection of weapon delivery tactics,
coordination of multiple aircraft, selection of the flight route and
position updating, and preparing for air-to-air combat. New display
formats were then devised to overcome the deficiencies, improving
mission effectiveness and survivability, and reducing workload. (General

Managing large schematics on a small computer screen. Developed
a method for squeezing a large schematic or diagram image onto a small
computer screen in a form that is still viewable and usable by a maintainer.
Termed FocalView, this system uses bit-mapped warping/compression
algorithms that do not require any content knowledge of the to-be-compressed
schematic. Based on an advanced perceptual-cognitive theory of human
vision, FocalView optimizes the use of virtually every screen pixel
while warping and compressing the surrounding area. Experimental validation
and strong positive user reaction was demonstrated in two separate
experiments. FocalView runs on commercial off-the-shelf hardware,
and can be applied to a wide range of military and commercial work
settings. (Air Force Research Laboratory)

Mission Planning Skills of USAF Fighter Pilots. The focus of
this project was on the planning needs of pilots using the AFRL Distributed
Mission Training (DMT) system. Interventions were identified through
a training needs analysis in which a set of high-payoff mission planning
skills were identified, promising interventions were extracted through
SME interviews and literature review, and a Delphi approach was used
to achieve consensus among a panel of experts concerning those interventions
that will have the greatest potential. The result was a set of concept
design specifications for the most promising interventions. In addition
a set of behaviorally-anchored rating scales to evaluate the quality
of mission planning by F-16 fighter pilots for air-to-air missions,
missions that historically have received little mission planning training,
were developed for the AFRL Warfighter Training Division. The scales
allow expert pilots (who are not expert researchers) to collect reliable
and valid process and performance measures so that the quality of
mission planning behaviors can be correlated with subsequent mission
performance (Air Force Research Laboratory).
Design of the Integrated Mission Planning System (IMPS). Planned
and conducted a human factors analysis, design, and evaluation program

factor. In the second analysis, the types of aircrew coordination
errors that contributed to accidents were identified and classified
into error types. (Army Research Institute, Aviation Research and
Development Activity)
High risk behavior in Army rotary wing aircraft. Matched computerized
data associated with indicators of high risk behavior previously identified
