• Application Domain Wireless Environment

• Probabilistic Segmentation Model

• Trace Database on Signal-Strength Readings

Motion Pattern

• Illustration on Sensory data

• Goal-Based Segmentation algorithm

• High-level goals can be recognized from
  low-level signal segments
• Each segment define a motion pattern

Reduce human effort in calibration for activity
recognition!
