Lead code writer Joe Oppegaard of Montana Banana Design has generated another early iteration of the Fort Vancouver Mobile app, this one demonstrating the GPS triggering of mobile devices within 3 meters at the fort site, as shown here:
The text blurbs in this example can be replaced by any form of media, including audio, video, animation, etc., and set to push to users on site and play when they enter the designated 3-meter (roughly 10 feet in diameter) hot zones.
Some comments from Joe on the coding process before and during this iteration:
"I found an open source QR Code reading library, which means that we don't have to link to another QR reading app, we can actually have one built in. It looks easy to use, though I haven't implemented it yet. The other piece of that puzzle is grabbing an image from the camera on the phone, but I assume that the Android libraries make that easy.
Secondly, I've also been catching up on accessing GPS data from the Android as well, which also isn't too hard. So that means hopefully pretty easily I can implement the "if the GPS loc is X, then vibrate the phone and fetch video Y. ...
The development environment allows me to feed GPS data to it, so I actually test it all out as if I'm actually walking around the Fort."
From a later message:
"I successfully have the app listening to GPS data and have set it up so that unique code will execute when you get 3 meters away from any specific lat/long pairs. So for example, if you walk within 3 meters
of the opening to the Bastion, the "Bastion" code will execute (right now all it does is tell you where you are, but is just a stub for where the video or informational page will show up later). When you get within 3 meters of the door to Chief Factor's house, the "Chief Factor" code will execute, etc.
I got the lat/lon coords from Google Earth. ... I would suggest using Google Earth (or go down there with a GPS) to grab all of the coords for any place that in the future you think you might want to have something happen at. We can always add content as we get it and place holders in the mean time.
The QR code library is looking to be a bit harder to integrate, so my suggestion would be that for now we focus mainly on the GPS auto-detection part of the app on the Android.
The phone emulator allows for setting up a "path", so I can feed it gps coords for testing as if you're walking around. I'm going to try and do a video of it tonight to show you what it's looking like."
