My principle is simple is always better. Sunglasses that connect with your fitness app or their own app. That glasses display various physical properties as you move via a laser that displays this data on the inner side of the glasses.
have you ever gone on a run with the music playing on the earphones? you're starting to get in the zone when the navigation feature chimes in "turn right in 10 feet" and just like that your concentration is broken, now you have to start all over again. Similarly, Constantly checking your Fitbit takes away from the experience of running.
The market has an existing Augmented reality solution but the two I found had too much going on which made them for one expensive and distracting which destroys the whole point of the glasses.
I found this really interestin DIY laser guidance system. And here the idea begins. the comment section was also full of ideas on how to impove the setup.
The glasses connect to your phone and using a similar method project data on speed, navigation, time and distance left to be covered. I don't think you need any more than that. A code would have to be created to correct images from getting crossed and blurry due to the telescopic nature of vision. The inner side of the glasses would also need a filter to prevent relection of sharp light back into your eyes. The outer side could be tinted to block out light even more. Using one-way glass would be preffered.
Could be used while running to pace yourself as well as navigation
Skating is hard and checking directions on your phone is risky and you crash into things, The glasess could really help on that end. Downhill skating is also dangerous and I think fewer people would be willing to do it if they knew how fast they were actually going.
Hiking- most phones can sense altitude and i think it would boost morale if you could actually see your progress. It starts to feel like you're not going anywhere once you've climbed for 4 hours and you still haven't made it to a rest stop.
Taking away unnecessary features and complex visual code a product has more use to more people as well as reducing cost making it more affordable.
Augmented reality was supposed to be the stepping stone to virtual reality. An actual practical product that focusses on utility instead of novelty is easier to sell at this point since almost everyone know's what virtual reality is now.
I however have no experience in the technical hardware required to build it ,so any ideas on that would be a big help.
