Camera Heart Rate, Low Power Location, Quantified Self Radio, and a Multi Sensor

  1. Measuring Heart Rate with a Smartphone Camera — not yet realtime, but promising sensor development.
  2. iBeaconslow-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.
  3. Analysis: The Quantified Self (BBC) — radio show on QS. Good introduction for the novice.
  4. Tinke — heart rate, blood oxygen, respiration rate, and heart rate variability in a single small sensor that plugs into your iOS device.

Brand in China, Radio Apps, Valued Free Text, and Brain TV

  1. E-Commerce Booming in China (Economist) — bad time for Google to be leaving, just as online sales take off. Chinese consumers in stores check quality by hand but buying online requires trust, aka brands. This is a turn towards Western-style commerce built on trademarks and brand promise of quality, and away from the prevalent wild East style of commerce built on cut corners, deception, and mistrust.
  2. Comprehensive GNU Radio Archive Network — collection of GNU Radio applications. (via Hacker News)
  3. The Glass Box and the Commonplace Book (Steven Johnson) — essay on connected useful text vs frozen glass-walled text. As with paywalls, I am not dogmatic about these things. I don’t think it’s incumbent upon the New York Times or The Wall Street Journal to allow all their content to flow freely through the infosphere with no restrictions. I do not pull out my crucifix when people use the phrase “Digital Rights Management.” If publishers want to put reasonable limits on what their audience can do with their words, I’m totally fine with that. As I said, I think the Kindle has a workable compromise, though I would like to see it improved in a few key areas. But I also don’t want to mince words. When your digital news feed doesn’t contain links, when it cannot be linked to, when it can’t be indexed, when you can’t copy a paragraph and paste it into another application: when this happens your news feed is not flawed or backwards looking or frustrating. It is broken.
  4. Charlie Rose Brain Series — streaming video of the TV shows about the brain. (via Mind Hacks)
