Atkins, M. Stella, Jiang, Xianta, Tien, Geoffrey and Zheng, Bin (2012): Saccadic delays on targets while watching videos. In: Proceedings of the 2012 Symposium on Eye Tracking Research & Applications 2012. pp. 405-408. Available online

To observe whether there is a difference in eye gaze between doing a task, and watching a video of the task, we recorded the gaze of 17 subjects performing a simple surgical eye-hand coordination task. We also recorded eye gaze of the same subjects later while they were watching videos of their performance. We divided the task into 9 or more sub-tasks, each of which involved a large hand movement to a new target location. We analyzed the videos manually and located the video frame for each sub-task where the operator's saccadic movement began, and the frame where the watcher's eye movement began. We found a consistent delay of about 600 ms between initial eye movement when doing the task, and initial eye movement when watching the task, observed in 96.3% of the sub-tasks. For the first time, we have quantified the differences between doing and watching a manual task. This will help develop gaze-based training strategies for manual tasks.
