Geo-location applications for mobile phones are becoming a hot item. This class will review the latest mobile applications plus the tools to make it possible. Some classroom and research applications for these new types of services will also be shown. We hope this session will inspire you to take on your own projects if you are ga-ga for geo-location. Bring your own smart phone and try some tools yourself! Presented during the 2011 Enriching Scholarship week at the University of Michigan.
