Wireless eye-tracking technology application and self-report measures to explore users’ approach to Smart Home Systems (SHS)

The relation between individual differences in some psychological traits and eye-gaze behaviorin participants exploringa Smart Home System (SHS)was considered.Real-time eye-gaze metricswererecordedwhile subjectswere engagedwith 5 tech-interaction(TI)areas with different levels of complexity in theSHS.Results suggestedeasiness to visually process a simplerTIcompared 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 externalLocus 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 SystemReward Responsiveness(BAS-RR)and fixation duration, suggestinga tendency for subjects with high BAS-RR to scan the TIswith more quick and dynamic visual patterns.
