In a recent interview, Vigna told the New York Times that future devices will be able to detect your elevation.
"These sensors will tell people what floor they are on in a building, or could be used to more precisely determine where you are in relation to your friends on a location-based service"
Vigna says they will also be able to monitor your heart and keep tabs on your health. Mood and excitement could be detected by monitoring perspiration. Location and surroundings could be determined using additional microphones, temperature, and humidity sensors.
This sensor-filled world will also affect video games. Sensors that can detect mood and excitement will usher in an era of video games that will factor in emotion during gameplay.
Vigna believes that in time sensors will move from your smartphone to other items as well.
"Sensors will be everywhere in the next few years and will be able to help people become more conscious of the environment and our own health," explained Mr. Vigna. "Your socks, shoes, glasses and even your garbage can will have sensors inside designed to help you manage everything from your effects on the environment to your health."
