I’m intrigued by the idea of using Google Glass during a presentation to avoid ever having to look at or touch a computer. I’ve taken a cursory look over the apps that are currently available, and tried out Your Show and Glassentation. I’m concerned about two things – one, pulling it off at all, meaning making sure that my audience is still focused on my talk and not my gadget, and two, being able to continuously engage the audience while referring to my notes quickly enough to not break the flow.

Are video tracking algorithms good enough to take the feed from a crappy digital camera, and tell me how fast I threw a baseball or how far I hit a golf ball? Last time I toyed with these over a decade ago, probably not, but now, they might be.
