Thomer developed a “Trust-Based (TB) Design
of Human-Guided Algorithms (HGA),”
for his thesis research. This design holds the
potential to offer operators better insight into
the solution process for decision making, improve
operators’ trust in the solution, and generate
superior solutions under the most challenging
of circumstances, such as those facing
fighter pilots in combat.
“In order to appropriately utilize algorithms
during a planner’s decision making,
HGA operators must trust the HGA and the
final solution,” explained Thomer. “I wanted
to look at how to optimize the operator’s trust
in a solution.”
He evaluated algorithms, solution steering
methods, and displays required to best match
the complementary strengths of human operators
and computer generated decisions, and
their ability to generate solutions that could
be appropriately trusted. Abstract hierarchy,
ecological interface design, and various trust
models then were used to enhance the operator’s
trust in the system. An HGA, including
the appropriate controls and displays, was
designed and developed. A human-subject
evaluation next was used to test its effectiveness.
The participants were presented with the
task of using the HGA to develop a routing
plan for military aircraft to prosecute enemy
targets. The results showed that TB design had
a significant effect on trust, human-guided algorithm
performance, and in some cases, the
quality of final solutions. |
