Empathy
“Seeing with the Eyes of another,
Listening with the Ears of another,
and Feeling with the Heart of another …”
Alfred Adler
Empathic Computing
Understanding
Systems that can understand your feeling and emotions
Experiencing
Systems that can help you better experience the world
Sharing
Systems that help you better share your experiences with others

Empathic XR
Extended Reality Systems that can
Measure | Share | Adapt to | Manipulate
Emotion and Cognition in real time
-Physiological (ECG, EDA, EMG, Pupil)
-Neurological (EEG)
-Behavioural (Speech, Posture, Movement)
Sharing Physiological States in Collaborative VR
ACM CHI’17
Data Collected
- Raw heart-rate
- Positive and negative affect schedule (PANAS)
- Relative head orientation
Results
- Higher positive affect
- More communication between collaborators
- Observer interaction needed
Sharing Physiological States in Collaborative VR

Lessons Learned
Social presences increases with
- Shared awareness cues
- Higher interaction
Shared physiological feedback can
- Increase communication
- Alter emotions but not real signals
- Increase awareness but may not change action

Next steps: Using EEG and other physiological sensors
Looxid
• Emotionally and cognitively adapt interfaces for learning and training
• Understand how brain synchronization works in collaborative XR
• Effectively share emotional and cognitive states to create empathy in
