Dear Aunt TUAW: location voodoo
Dear Aunt TUAW, I've recently become the proud owner of a 3rd generation iPod touch. I found the Nike+ app that uses some strange GPS/wifi-triangulation scheme to locate me and how far I run/walk. How does the iPod touch do this? Is it magnets? Smoke? Mirrors? Is this a reliable location-reckoning system? There are a lot of rumors abounding on the Interwebs, and I know you'll get to the bottom of it, Auntie. Love & tickles, Your nephew Marc H.
Looking Forward to the 3G iPhone: GPS
There are just two weeks left until the 3G iPhone bows with its new onboard GPS. The new iPhone will use several location methods using data from providers including Skyhook Wireless, Google Maps and the US Department of Defense NAVSTAR Global Positioning System. From most to least accurate, these are discussed after the jump.
Nintendo DS does geopositioning with WiFi
A highly reliable source just sent in this image of a Nintendo DS using WiFi triangulation -- rather than GPS -- for geopositioning data (sorta like that iriver W10 we mentioned back in January). Not sure when this might be commercialized, but it would potentially make it possible to add location-based data to DS games without requiring some sort of GPS add-on. Click on for a full-sized shot.
