| Summary: | The main objective of this work is to study the
degree of engagement levels of human subjects in
completing a series of tasks based on their physiological
signals. The tasks are in the form of tracking a set of
trajectories on the computer screen by using a mouse. .
The subjects are chosen randomly based on both sexes,
aged from 20 to 40 years old. After completing the
required tasks in a series of experiments, the subjects
are given a set of questions to answer In particular, for
the experiment, the subjects are asked to track a set of
prescribed paths within the allocated times in order to
adhere to different speed constraints. Various shapes of
trajectories with various colours are given to the
subjects in order to study the degree of engagements
while performing the tasks. In estimating the degree of
engagement level, the physiological signals; namely the
electrooculogram (EOG) are recorded by using the Gtec
data acquisition system. By using these signals,
information on the endogenous type of eye blinking is
extracted. After completing the experiments, a set of
questionnaires are given to the subjects to measure the
degree of engagement level. The questionnaire works as
an important tool to validate the engagement model
deduced from the experiment done earlier by the
subjects. Preliminary analysis on the questionnaire
shows a good match |
