Ground Projected Information Display (for night jogging)


This will be very short, and not so sweet, kids...

I run at night, while the wee babies are dreaming of a more fit daddy, and the woodland creatures are doing their best to scare me from the roadside (and they do).

I have my iPhone with me for tunes, but I felt that I didn't look stupid enough, so I came up with a chest-mounted ground projection rig. It both illuminates the path (and armadillos) directly in front of me and displays information, such as mileage, time, maps, etc.

I like it. It could be more comfortable to wear, but that's for version 2.

Ingredients:
One iPhone
One iPico iPhone projector (only $85!)
An iPhone padded running case
Some velcro

You can project anything on the ground, like Google maps while GPS is running, Youtube videos of countdown digits, etc.

I chose to write myself an iPhone app which does a few things:
1. Displays info I want, such as my mileage and the current time
2. Only projects info when I touch the screen for stealthier animal evasions
3. Constantly samples the iPhone gyro and accelerometer and counter adjusts the projected image. This results in less sway and bounce in the projected image on the ground while running.

The third feature is in prototype phase, so I'm not releasing an app yet (ever?). It works well enough, and the effect is a greatly reduced bouncing of the information circle on the ground in front of me. It feels neat, like an augmented Google Glass display, only everyone can see it! Extra dork points! :D

Nice work. I really like the idea. If you are looking for recommendations on V2 I'd suggest adding a shoulder mounted micro gimbal with fixed pitch angled toward ground. Here is a video example of a camera gimbal used on a micro quad rotor RC. This one was implemented for level orientation but should give you some ideas. http://m.youtube.com/watch?v=otTO-glUc8g&desktop_uri=%2Fwatch%3Fv%3DotTO-glUc8g
It would be good to harness this technology http://bit.ly/153yWAM then you could strap the projector to your arm rather than trying to recreate a scene from Ironman.
You've got my vote, mainly for just being a better runner than me.

Thanks friend.
If you can step out your front door without twisting an ankle, then you're already better than me. :)
