Google product manager Steve Lee demonstrates how Google's 'Latitude' programme allows people to locate someone's whereabouts from software installed on their mobile phones.
The new feature will allow mobile phone users to share their location with others on a Google map.
The software finds a location by using global positioning systems and wi-fi connections. Each user will need to manually turn on and off the tracking software, which will limit when they can or cannot be seen.
