'Dorothy' lets you click your heels to hail a cab
What if you could click your red heels to get home, like Dorothy from The Wizard of Oz? A new wearable concept -- aptly dubbed "Dorothy" -- might let you do just that. It consists of a small clip called "Ruby" that attaches to your shoe and communicates with your phone via Bluetooth. The clip has an accelerometer and, when you tap your heels together three times, it sends an alert to the companion app. What the app does with that alert is up to you, but the company behind Dorothy, iStrategyLabs, is working to integrate the Uber API to automatically call an Uber to your location.
