A keynote from the annual Trident Technology Conference for schools in 2016, when I was asked to cover the Internet of Things and wearables. As it's still an emerging market for schools, I chose to set the audience some challenges about applications for these technologies in education, and what were good\bad ideas (ie didn't cross the 'creepy line' for wearables). And the last few slides (for those who weren't there) was a quiz - spot the one that wasn't real!
