Sometimes people are hard to read. Why not leave all that work to a computer? Perhaps you could use this experimental app that works in Google Glass. Aim Glass's camera at a person's face and the app reads the human's facial expression and tells you to what extent the person is feeling happy, sad, angry, or surprised. As a bonus, the app guesses the person's age and gender. Evaluating whether you want to hit on that person is still up to you.
Call it a case of virtual selection. Testing out Project Nightjar's experimental video game, I peered through the world in mongoose-tinted glasses, looking for the eggs of a nesting nightjar -- a nocturnal bird in the family Caprimulgidae. The clock ticked as I made my selection, and then I found the nesting mother. While I played the game, the researchers behind the project gained a little more insight into just how well natural camouflage works.
Surveillance cameras permeate modern life. Mounted in convenience stores, retail outlets, bars, clubs, ATMs and elsewhere, silent observers record everything from the mundane to the criminal. The cameras serve a dual function as both deterrent and instant legal record. In light of the police shooting of unarmed Michael Brown in Ferguson, Missouri, national attention has focused on wearable cameras for police officers. For the (less lethal) weapon manufacturer Taser, there is opportunity in this civic need.
Fitness trackers use suites of sensors and algorithms to turn data from your training regimen into (hopefully) meaningful information about how race-ready you are. But for the rest of the time—when you’re sitting at a desk—there’s not much for devices to do. Spire, a clip-on tracker that looks like a small, silvery stone, monitors a more subtle aspect of your physiology: your breath. By measuring the small vibrations and abdominal movements caused by inhaling and exhaling, Spire’s analytics software can determine how stressed or focused you are, the company says. If you haven’t taken a deep breath in a while, Spire’s smartphone app will kindly remind you. It will even guide you through a calming exercise.
