There are some really solid ideas in here. I had a similar idea when I was starting to think about my venture pitch, and was happy I did not pursue it (mine was a lot less sophisticated). I love the application of this in moving away from schools that are based on timeliness and set schedules. With a wearable like this, you could really allow kids to roam and define how they spend their day much more, since things like attendance and tracking what students are up to are automated. My concerns with the venture seemed to be highlighted in other comments… the steep price per student, competition with current guys, and issues with the optics of privacy. I don’t doubt that we will see elements of this venture show up in schools in the coming decade though, so good forecasting!
