Camera Heart Rate, Low Power Location, Quantified Self Radio, and a Multi Sensor
- Measuring Heart Rate with a Smartphone Camera — not yet realtime, but promising sensor development.
- iBeacons — low-power, short-distance location monitoring beacons. Any iOS device that supports Bluetooth Low Energy can become an iBeacon, and can detect other iBeacons when they are nearby. Apps can be notified when iBeacons move in and out of range of the device, and can monitor the proximity of iBeacons as their proximity changes over time.
- Analysis: The Quantified Self (BBC) — radio show on QS. Good introduction for the novice.
- Tinke — heart rate, blood oxygen, respiration rate, and heart rate variability in a single small sensor that plugs into your iOS device.
