Based on "VRception"[1], a cross-reality toolkit allows users transfer to any steps between (simulated)Augmented Reality, (simulated)Augmented Virtuality and Virtual Reality with its alpha-blending function, I designed this visual search experiment under 6 conditions with these 3 realities and 2 difficulties. High difficulty task has more distractors than the low one.
When the search begins, player should search out the specific target mentioned on a white board from distractors, point and click by using an HTC controller before time runs out. Player has to finish a training session before 6 tasks.
Experimental data as well as EEG signals and eye tracking data were logged into csv files for cognitive load and attention analysis.
Note: This repository only includes eye tracking validation, training session and questionnaire, 6 tasks were removed. Run 03_Training.unity under Assets/Visual Search/Scenes to check how the visual search goes like. You can find pictures and video about the visual search tasks under different conditions from my portfolio https://www.artstation.com/artwork/VJnkDP?notification_id=6033418437
