As Humans, we are always engaged in activity and it has been considered to be one of the most important ingredients of context awareness and ubiquitous computing. At the lab we pursue the goal of capturing the activity of individuals, groups and crowds on a city scale.

Group Members


Sensing the Activities of Individuals

  • ActionSLAM (infrastructure-free indoor location tracking)
  • Topic models for activity routine discovery

  • Less supervision in activity recognition
  • Ambient sensing in activity recognition and semantic location awareness

Sensing Urban Behavior

  • Urban activity recognition
  • Social media as a probe for activity
  • Collective behavior on city scale events
