GPS seems to be the easier development stream with several different applications and API\'s to aid in development such as:

1. Layar
2. Wikitude
3. Junaio

These solutions have less need for intense coding knowlede and are a bit more userfriendly but are still far from a WYSIWYG editor.

Initially we feel that the educational ROI for GPS based AR is much lower than fiduciary marker based AR. For that reason we feel that time spent developing the marker based tech is much more useful and interesting.
