A scoping review of eye tracking metrics used to assess visuomotor behaviours of upper limb prosthesis users

Abstract: Advanced upper limb prostheses aim to restore coordinated hand and arm function. However, this objective can be difficult to quantify as coordinated movements require an intact visuomotor system. Eye tracking has recently been applied to study the visuomotor behaviours of upper limb prosthesis users by enabling the calculation of eye movement metrics. This scoping review aims to characterize the visuomotor behaviours of upper limb prosthesis users as described by eye tracking metrics, to summarize the eye trac… Show more

“…However, future researchers could consider implementing other systems that might provide a more in-depth examination of the contribution of the visuomotor domain during DT reactive balance. For instance, several systems and programming technologies allow for the capture and complex analysis of eye-tracking metrics via human–computer interactions [ 65 , 66 ]. Examining eye movements during different visuomotor tasks could potentially be more sensitive than head movements for calculating CMI.…”

“…Eye tracking reflects the user's visual attention and gaze direction [20], recorded from cameras or glasses that capture the movement of the eyes and pupils and processed by using methods such as gaze fixation, gaze switching, or gaze estimation to decode the user's intention [12,21]. Gaze fixation is used when the user is looking at a specific target for a certain amount of time and activating a corresponding hand gesture [22,23].…”

“…Gaze switching is a method adopted when the user is shifting their gaze from one target to another and activating a corresponding transition between hand gestures [24]. Gaze estimation involves estimating the 3D position and orientation of the user's gaze and mapping it to the 3D position and orientation of the prosthetic hand [21].…”

“…The technology has allowed exploration of understanding of the role of gaze in reaching, manipulation [3,4], sports [5] and skills acquisition [4]. Other eye-tracking systems can be used to control computer cursors but, as they rest on the desk, they have less use in applications where the subject needs to move about [6]. More recently, this exploration has moved into the investigation of prosthetic grasping [7,8].…”
