This lecture will arm Android device architects with the tactical knowledge they need to navigate the Android Sensor subsystem and make knowledgeable design choices to improve user experience and improve battery performance. It will cover:

  • Hardware architecture and trade-offs including latency, power, and software architecture implications:
    1. Sensor selection
    2. What is sensor fusion?
    3. Sampling Rates: Is more always better?
  • Wake up events and power considerations
    1. Is a co-processor the answer?
  • Gesture Detection Algorithm processing location and considerations
    1. Where to perform gesture detection
    2. Buy versus make
    3. Porting algorithms to another processor
    4. Testing human interface sensors
  • Integration into the Android Sensor Frameworks
    1. Must have software checkpoints
  • Testing methodologies
    1. Creating tools to aid develop and collect data

I really liked this presentation. The information was well organized and succinctly presented. And I felt the speaker had a good amount of practical experience backing her comments. Well done.
