This is a very interesting idea… I spent a good amount of time looking at the Estimote site and could see how this may hold potential. Originally, I was unsure of what would be different between these beacons and a QR code, and I suppose they serve similar functions (although beacons push data and notifications, while you have to activate a QR). The only challenge I see with this is that perhaps we don’t want students interrupted more by their devices. The market here looks positive, and with greater connectivity I could see these playing a big role bringing education outside the classroom. Thanks for sharing!
