Conceitos essenciais
This article presents an advanced analytic dashboard, A-DisETrac, that supports real-time computation and visualization of both traditional and advanced gaze measures for distributed multi-user eye tracking. The system was evaluated through two pilot studies on collaborative puzzle solving and competitive battleship gaming, demonstrating its utility in analyzing visual attention and cognitive load during group activities.
Resumo
The article presents A-DisETrac, an advanced analytic dashboard for distributed multi-user eye tracking. Key highlights:
-
A-DisETrac supports real-time computation and visualization of both traditional gaze measures (fixations, saccades) and advanced gaze measures (ambient/focal attention coefficient, real-time index of pupillary activity) for distributed multi-user eye tracking.
-
The system was evaluated through two pilot studies:
- Collaborative puzzle solving task:
- Observed a strong negative correlation between the group's ambient attention coefficient and the time taken to complete the puzzle, indicating that groups with more ambient scanning behavior took longer.
- Observed high cognitive load (RIPA) across all groups.
- Competitive battleship game:
- Did not find a significant difference in ambient/focal attention between winners and losers.
- Observed higher average RIPA in winners compared to losers, but the relationship was not statistically significant.
-
A user experience evaluation showed the A-DisETrac dashboard provides a comparatively good user experience, with "excellent" results in "Attractiveness" and "good" results in "Efficiency", "Stimulation", and "Novelty" compared to benchmark data.
-
The system supports data restreaming, allowing users to replay and analyze past experiments.
Overall, the article demonstrates the utility of A-DisETrac in providing real-time insights on visual attention and cognitive load during collaborative and competitive group activities using distributed multi-user eye tracking.
Estatísticas
The time a group took to complete the puzzle is related to the ambient visual scanning behavior quantified by the group's ambient/focal attention coefficient (r = -0.9722, p = 0.0056).
