Sensor data is being collected from a growing variety of sources and must be wrangled from devices to the cloud for analysis. This sensor data can provide context awareness and personalization to improve health, well-being, productivity and safety when algorithms analyze the data along with additional context factors. The future holds an exciting potential for truly smart devices that can provide insights by fusing data from multiple sensors and user context over time.

22. HEART RATE DATA

23. RAW DATA
“Your heart rate is 95 bpm.”

24. CONTEXT MATTERS

25. heart rate estimation + user context + insight
“Your heart rate is 95
bpm.”
“Your heart rate is 95 bpm
and you have been sitting
in a meeting for an hour.”
“Your heart rate is unusually
high today at 95 bpm.
Consider skipping the coffee
before your meeting.”

29. This morning’s resting heart rate was higher
than 61bpm, your 30-day average.
Dehydration may be the cause. If you think
you were dehydrated last night, make up for it
today with 8 glasses of water.
Start with Hydration
