The technology has a practical emergency application: It can tell if you've been in a car accident. If your deceleration is fast enough, then, by definition, you've been in a collision. It would be theoretically possible to develop an app that calls 911 when you've been in a crash and relays information about your location and perhaps some details of the incident.

The system can also out-Siri -- theoretically. Virtual personal assistants in the age of Siri derive value from understanding regular human speech. But tomorrow's assistants will earn their keep by understanding actual human behavior.

Note that every data point gathered can be connected to a universe of useful information. For example, by knowing where you drive and also where you tend to buy gas, an app could suggest cheaper gas at stations near the routes you drive on a regular basis.

There's another "ambient awareness" app called that tells you when someone you know -- or someone who knows someone you know -- is nearby.

A combination of a system like Alohar's and an app like Highlight could tell you how you're connected to the strangers around you (those who also use the same app). Here's a guy who goes to the same gym you do. There's a woman whose kids go to the same school as your kids. One of your neighbors works in a building next to your workplace -- maybe you should carpool.
