(The second part of this two-part series addresses security risks posed by the Internet of Things.)Object by object, for better or worse, the world is becoming ever more connected. Computer scientists have been laying the groundwork for a connected world for decades.
The first object on the internet was a Coke machine at Carnegie Mellon in the early 1980s.
One may measure temperature, another measure the lighting, and another track whether anyone is home.
Its promises include better healthcare, energy savings and a more connected world.
One of its big challenges is to keep users’ data safe from hackers. He's a computer scientist at Carnegie Mellon University in Pittsburgh, Pa.
Each wave, he says, joined people and computers in a new way. Companies began using computers in the 1950s, and personal computers appeared in homes in the 1980s and 1990s.
During those years, scientists figured out how to make computers do work and store data. Many technological advances have made it possible to build smart devices, says Hong.
Weiser didn’t describe his vision as the “Internet of Things.” He used the phrase “ubiquitous computing.” (The word refers to something that is found everywhere.) But the two terms essentially mean the same thing.
He imagined a world where anything could be turned into a computer.At the time, there were about 6.7 billion people on Earth. “But I think it’s a lot more fun to find out how things work.”Take the 94Fifty. A gyroscope is a device that looks like a freely spinning wheel in a small frame. (GPS, or the Global Positioning System, is the technology behind navigation apps, for example.According to predictions by Gartner, a technology company, more than 20 billion devices will be online by 2020. Maria Ebling wants people to know what makes smart objects so smart. It uses satellites to pinpoint an object’s location.)A smart medical device might use sensors to measure a patient’s blood pressure, pulse or blood oxygen levels.These devices might communicate with users through their smartphones or home computer networks.Like every new advance in technology, the Internet of Things brings both excitement and challenges.Will this ball help a driveway hotshot become the next Le Bron James? But many experts think it may well be part of a revolution in technology. It gets its name from the dimensions of an NBA court: 94 feet by 50 feet (28.7 by 15 meters). It then can use these data to calculate things and provide useful information to help a player get better. The Internet of Things is the idea that ordinary objects can be turned into “smart” objects that measure and interact with their environments. A smart lightbulb turns itself off when not in use.
