The next generation of smart phone could combine the data from its gyroscopes with a built-in compass to allow you to track your movements when indoors even without GPS. Such a system could be useful for shopping mall managers, factory bosses for worker safety and security and office workers hoping to manage the flow of people through buildings. It could also be used to enable location based services and to help users navigate to specific meeting points or shops.
