Toward A Pervasive Gaze-Contingent Assistance System: Attention and Context-Awareness in Augmented Reality

Mobile devices with high-speed connectivity provide us with access
to gigabytes of high resolution images, videos, and graphics. For
instance, a head-worn display can be used to augment the real
view with digitized visual information (Figure 1). Eye tracking
helps us to understand how we process visual information and it
allows us to develop gaze-enabled interactive systems. For instance,
foveated gaze-contingent displays (GCDs) dynamically adjust the
level of detail according to the user’s point-of-interest. We propose
that GCDs should take users’ attention and cognitive load into
account, augment their vision with contextual information and
provide personalized assistance in solving visual tasks. Grounded
on existing literature, we identified several research questions that
need to be discussed before developing such displays.
