How can integrating gaze information improve models' performance in bridging ego-exo activities?

Integrating gaze information can significantly enhance models' performance in bridging ego-exo activities for several reasons:

Visual Attention: Gaze information provides insights into where individuals are looking while performing tasks, indicating their visual attention. By incorporating this data, models can better understand the focus of the individual and align it with corresponding actions in the demonstration videos.

Contextual Cues: Gaze patterns often reveal implicit cues about a person's intentions, decision-making process, and cognitive load during task execution. Models leveraging gaze information can use these contextual cues to infer underlying motivations and strategies behind actions performed in egocentric videos.

Alignment of Actions: Gaze signals help establish a connection between what an individual is observing (exocentric view) and how they are executing tasks (egocentric view). This alignment aids in mapping procedural steps from different viewpoints, enabling smoother transitions between asynchronous activities across views.

Enhanced Understanding: By considering gaze alongside video data, models gain a more comprehensive understanding of human behavior during task replication. This holistic approach leads to improved accuracy in associating actions across ego- and exo-centric perspectives.

In essence, integrating gaze information offers valuable behavioral context that complements visual data, leading to more robust and accurate modeling of human observational learning processes.
