“…Our data is consistent with the finding of previous works [21,23,24]. The time that the pupil starts to dilate (1.5s before tooltip-start) in this study is same as that of Richer and Beatty's finding, while the peak duration (2s after tooltip-start) is longer than that of Richer and Beatty's (0.5s).…”

“…The authors found the typical pupil dilation pattern to a simple movement is that pupil dilates at around 1.5s before the movement and peaks afterwards at around 0.5s. This pupil dilation pattern was confirmed by other works [21,23]. For example, in a visual target search study, Privitera et al [23] found a quite similar pupil dilation pattern to that in Richer and Beatty's finding when the participants successfully detected a target and responded with a key-press.…”

“…The 7-second window is motivated by considering the extra movement time (about 1s-2s) before the tool leaves in our study compared with others who noted pupil increases start 1.5s before the stimulus [21,23,24] and the pupil continuous to dilate afterwards to a peak value in a few seconds e.g. 3s-window in [23] 4s-window in [24] and 5s-window in [21]. Relative pupil diameter changes in the window were derived by subtracting each sample from a baseline pupil diameter which was the mean of the pupil size during the first second of the window.…”

“…Since the frequency of pupil response to a movement is typically lower than 0.5Hz [21,23,24] and the frequency of the Fitts' tool movement under laparoscopic environment is usually around 0.5Hz [6], in order to avoid overlap of the pupil dilation curve, we used discrete Fitts' pointing [9] by waiting 10s before each tooltip move. Such discrete goaldirected movements and related eye-hand coordination are elementary parts of any human-computer interaction and arise in the vast majority of our interactions with surrounding objects.…”

Pupil size is known to correlate with the changes of cognitive task workloads, but how the pupil responds to requirements of basic goal-directed motor tasks involved in human-machine interactions is not yet clear. This work conducted a user study to investigate the pupil dilations during aiming in a tele-operation setting, with the purpose of better understanding how the changes in task requirements are reflected by the changes of pupil size. The task requirements, managed by Fitts' index of difficulty (ID), i.e. the size and distance apart of the targets, were varied between tasks, and pupil responses to different task IDs were recorded. The results showed that pupil diameter can be employed as an indicator of task requirements in goal-directed movements-higher task difficulty evoked higher valley to peak pupil dilation, and the peak pupil dilation occurred after a longer delay. These findings contribute to the foundation for developing methods to objectively evaluate interactive task requirements using pupil parameters during goal-directed movements in HCI.

No sistema ubiquitina-proteassoma é necessária a participação de três enzimas, E1 (enzima ativadora de ubiquitinas) que ativa a ubiquitina com gasto de ATP, E2 (enzima conjugadora de ubiquitinas) que forma um complexo poliubiquitina, e E3 (enzima ubiquitina-ligase) que faz com que a poliubiquitina se ligue ao substrato que deverá ser degradado pelo proteassoma (Figura 1) (Baptista et al, 2010;Lecker, 2003).…”
