The Extended Self: Agency and Trust in Robotic Avatars

Perceptual and Cognitive Foundations for Post-Biological Control Systems
Workshop at AIxRobotics 2025
December 2025

Workshop Overview

In the context of Moonshot Goal 1, robotic avatars are envisioned as tools for enhanced autonomy, accessibility, and superhuman action. However, user acceptance and control efficiency depend not only on performance, but on the felt experience of control and on the user trust of the system. Loss of sense of agency leads to loss of sense of trust, disengagement, and system rejection.

This workshop addresses a pressing gap: how to design, evaluate, and prototype avatar control systems that support a robust sense of agency, especially under constraints of latency, AI assistance, or limited embodiment; from a multidisciplinary and transdisciplinary perspective.

Aim & Scope

This workshop explores how the Sense of Agency (SoA), the perceptual feeling of being in control of one's actions and their effects, shapes the experience, usability, and adoption of robotic avatars.

Robotic avatars are intelligent physical or virtual bodies that users can project themselves into, enabling remote action, communication, or augmentation beyond biological limitations. The workshop connects cognitive neuroscience with robotics, presenting SoA as a measurable and designable quality that determines whether users identify with and effectively use robotic embodiments.

Key Topics

  • Perceptual feedback and synchronization in avatar control
  • Measuring and designing sense of agency
  • Trust in post-biological control systems
  • Latency compensation and AI assistance
  • Multimodal interfaces for robotic embodiment

Workshop Structure

This workshop is a hands-on workshop where participants will experiment, engineer, and experience differences in perceived sense of agency depending on control parameters. The workshop is structured into three cohesive sessions, balancing theory, experimentation, and synthesis:

Session 1: Theoretical Foundations of Avatar Agency (60 minutes)

  • Talk 1: Is agency an objective concept? Multimodal Recognition, BCI, and the Sense of Agency - Sarah Cosentino
  • Talk 2: Investigating the Sense of Agency in Brain-Controlled Daily Tasks - Luca Nunziante

Topics covered include: temporal contiguity, sensorimotor congruence, embodiment, and cognitive transparency.


Session 2: Hands‑On Experimentation (75 minutes)

Participants self‑organize in small teams and select from three tracks, designed for scalability and inclusivity:

  • Track A: Multisensory Congruence Micro-Experiments
  • Track B: “Betrayal of Agency” Challenge
  • Track C: Avatar Embodiment Design and Boundary Experiment

All tracks aim to explore how system‑level design choices affect perceived control and embodiment.
Coding skills are welcomed but not required. Bringing your own laptop for experimenting with provided scripts is strongly encouraged.


Session 3: Presentations and Theoretical Integration (45 minutes)

  • Team presentations, demo showcases
  • Interactive panel discussion: What Makes an Avatar Feel Like Me?
  • Summary and guidelines for designing SoA‑aware control architecture
  • Live Demo: A ROS 2 Platform for Synchronized Multimodal Data Replay and Perceptual Prototyping

Submission Information

Beside regular papers, position papers and survey papers are also welcome. Posters are also accepted. All the contributions to the workshop must be submitted according to the standard IEEE format as specified in the AIxRobotics guidelines. Papers will be refereed and accepted on the basis of their merit, originality, and relevance. Each paper will be reviewed by at least two Program Committee members. Papers can be submitted via email at: arkairosworkshop@gmail.com
