Influence of viewing behavior on estimation performance of certainty using features of eye-movements
Minoru Nakayama, Yosiyuki Takahasi (Tokyo Tech) PRMU2007-237
Abstract (in Japanese) (See Japanese page) 
(in English) To determine the performance of estimating the degree of
``strength of belief'' (SOB) of responses using eye-movements,
the features of eye-movements were extracted
while subjects answered questions and reviewed their own responses
to multiple choice tasks.
All fixation points of eye-movements were classified into visual areas,
or cells, which corresponded with the positions of questions.
The high and low SOBs for the answers were defined
according to each subject's declaration of certainty.
The estimation was conducted using Support Vector Machines (SVM)
with features of eye-movements between two successive fixations.
In the results, the overall estimation performances were significant
when the prediction was calculated using certain combinations of features
for answering and reviewing sessions respectively.
In comparing feature combinations of eye-movements
for significant estimations
between answering and reviewing sessions,
significant combinations components of features
between the two sessions did not coincide.
As some features between the two sessions were significantly different,
the SOB estimation procedure depends on the viewing mode, such as
answering or reviewing.
