Streszczenie:
The present paper aims at describing the concept of how
the interaction with computer devices may bene t from
joint input of users emotional state and his/her eye
movements characteristics. We claim that emotions
regulate visual attention, changing its formal
characteristics and thus in turn in
uence the user's
behaviour. We hypothesised that during interaction with
an interface, positive mood will enhance exploratory eye
movements. Participants of the study completed positive
or neutral mood induction procedure followed by free
viewing of classical paintings on computer screen. During
the whole experimental procedure, the users' eye
movements as well as their brain activity were recorded.
Results con rm that positive mood changes the dynamics
of visual attention. When completing a computer task,
people's eye movements indicate shift from ambient
toward more focal attention mode. However, positive
mood slows down that process, fostering visual
exploration of the presented stimuli. Obtained results are
discussed in the context of self-adaptive user interfaces
idea suggesting that the information about the users'
emotional state together with visual attention
characteristics and gaze information could be used as an
input channel in order to create better user experience.
