Hello Stephen, I really like the concept of your venture and found both of your pitches well constructed and informative. I will have to agree with the comments below that the privacy issue is a major deterrent for me as an EVA. I have concerns about what companies could do with the data that is collected from a device like this – it is too easy to use this kind of information for commercial purposes. I do feel that the idea is very interesting and could have huge impacts on education and school structure. However the market for wearables is huge and you would be hard-pressed to out-develop giants like Apple and Google.
