Bugfixing, region functionality
The current version has some more bugfixes concerning loading progress of mediascapes, switching between scapes, playback functionality etc… I wrote a little test program which simulates different GPS coordinates to trigger different mediaregions. Now I can test playback behaviour when the “user” changes a region, which is currently reduced to a simple stop of the […]

Today I worked on coordinate comparison. One thing I forgot to mention before was, that the iPhone’s Location API provides Latitude and Longitude coordinates (WGS84 ellipsoid), but the location coordinates of media regions from mediascape are stored in UTM (Universal Transverse Mercator) system. To convert these coordinates was quite a job. A great help to […]

I wish an API….
Today I tried to get into mscape (2.1). It’s a shame there’s no API and the scripting is very limited. Even the GPS data is only readable, so you can’t use any filter (PLEASE correct me if I’ve missed something). It seems the only chance to use it’s media mapping is via the .msl file […]

This was my first experience with this interactive drama and I was very surprised about the effect. From the very first you’re animated to search the scenes, […]

First GPS – media combination
Today I tried a nice application called mscape. You can create your own media scape, based on map data. This means, you’re drawing areas on the map where different mediafiles (video audio) will start to play on your GPS compatible PDA or cell phone. It was quite fun to play with it, as long there […]
