DAMN there are so many things this would be amazing for!! my mind is exploding
practicing my trumpet, i could have the music scrolling in front of my eyes. maybe a visual metronome. what if i could get cue reminders while playing in orchestra! what if i were in a live show on stage, like a rock concert, and i could control electronic audio or visual effects while my hands are tied up on a guitar.
at the manufacturing plant i work in, i could document things in a flash if i could connect the databases i'm building in filemaker pro with google, and have corrective and preventive actions noted on the fly. maybe get on the fly pareto charts or fish bone diagrams built from the quality data we are collecting, that pop up on the glass while i'm looking at something physically in my hand on the factory floor.
working out at the gym, i could have the glass record the weights and reps as i count them out, and maybe show me what i did last time, instead of having to stop and pull out my notepad. i could pull up videos or pictures of technique demonstrations to mimick while i'm doing the exercises. i bet that thing could also pick up your heartbeat from your temples and monitor that.
i could be riding around on the moto and program it to record a 10-second video every time i say "SHIT!" or "F**K!" i could record my lap times at the track without pushing the lap button with my clutch hand right when i need to concentrate on braking really hard. it could show you your sector times. it could blink where you braked the last time jesus this thing could turn us into superhumans, not lazy bastards
