Navx launch his own platform
Navx, a french company selling customized voices and POI for GPS, seems to go also in the UGC content. They just announced yesterday the opening in public beta of their platform.
This seems very similar to what 8Motions is doing, except that they are focused on the GPS market. While GPS is a big market, I stilll doubt that GPS users will be big UGC contributors: the primary goal of a GPS is to help you to navigate but it will be far from being a perfect device to create UGC.
Our objective is to bring the ability to create user generated content related to geolocalisation with a clear focus on mobile, which is in our view the most interesting device for this. Export is possible for plenty of format, including GPS to consume some user generated content.
Anyway, good luck for NavX, and we will see how the platform will evolve!
