The relation between individual differences in some psychological traits and eye-gaze behavior in participants exploring a Smart Home System (SHS) was considered.

Abstract
The relation between individual differences in some psychological traits and eye-gaze behavior in participants exploring a Smart Home System (SHS) was considered. Real-time eye-gaze metrics were recorded while subjects were engaged with 5 tech-interaction (TI) areas with different levels of complexity in the SHS. Results suggested easiness to visually process a simpler TI compared to complex ones, in terms of higher number of fixations and of slower Time To First Fixation (TTFF). In two of the TIs (Living Room and Bathroom) we found a negative correlation: between the external Locus of Control (LoC) and the number of fixations, which might indicate a possible tendency for individuals with low external LoC to explore more actively complex TIs. A negative correlation was found between Behavioural Activation System Reward Responsiveness (BAS-RR) and fixation duration, suggesting a tendency for subjects with high BAS-RR to scan the TIs with more quick and dynamic visual patterns.
