I could realize the advantage of technology in the FIFA World Cup soccer tournament for the first time during Italy vs Costa Rica match, which was played a couple of days back. In the 2nd half, Costa Rica's Bryan Ruiz headed the ball off the bottom of the crossbar...The ball hit the crossbar, bounced just inside the goal line and then bounced back to play. By naked eye it was very difficult to judge if it was a goal or not. But the referee did not have any issues as the "Goal Line" system quickly confirmed the goal. Don't know if any other matches also could make use of the "Goal Line" technology.
Technology doesn't replace people. Maradona's "hand of god" was seen by many and was available on replays right there with those days of technology. Referee decision is not to be overruled by any technological advance - it's the "people and procedures" domain.
Zidane cannot be excused by any audio recording. Provocations are part of the sport psycho war and any player of World Cup level should know it.
This technology was used for the America's Cup (won by Oracle), it completely changed the way this kind of boat race could be seen, especially for the non-expert watchers. It definitely made the races much more attractive.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
