1 Sensing Group Behavior Continued Tarek Abdelzaher Dept. of Computer Science University of Illinois at Urbana Champaign Sensing Recap (So Far) Publication Recipe #1: The “Surrogate Sensing” Recipe Step 1: Find/motivate an interesting new application (monitoring some aspect of a person’s activities or context) Step 2: Show that it is hard to measure/detect it using current “traditional” approaches Step 3: Collect a new combination of “surrogate” measurements of the activity or context using readily available sensors (typically those sensors are not intended to measure this type of activity or context hence “surrogate”) Step 4: Evaluate the quality/speed/accuracy of identifying the desired activity or context using those measurements Step 5: Identify challenges, if any (e.g., resource demands, latency, environmental diversity, need for unsupervised learning, etc.) and show how to overcome them
