Context:
Augmented Reality (AR) interfaces are increasingly used to enhance human perception and interaction with digital content, yet their potential for exploring temporal and bodily experience remains underexplored. Delayed embodiment through first-person replay offers a novel approach: users see their own past actions from a first-person perspective, creating a temporal shift in the sense of agency and presence. This thesis would investigate how such delayed self-representations influence body ownership, motor learning, and decision-making within AR environments.
The main objective is to analyze whether replaying a previously experienced activity in first-person view (using Snap Spectacles) alters self-perception or action perception.
The project will be developed in Lens Studio (https://lensstudio.snapchat.com) and Snap Spectacles (https://www.spectacles.com)
Protocol:
Participants perform a task in AR (e.g., social interaction, obstacle course, creative activity).
They later watch the recording of their experience (edited with or without stabilization, motion blur, sound effects, etc.).
Participants complete delayed embodiment questionnaires assessing agency, ownership, and self-identification.
Requirements

- Object Oriented Programming skills (C/C++/C#), knowledge of TypeScript is advantageous
- Knowledge of Game Engines (Unity, Unreal, Lens Studio) and Augmented Reality is advantageous
