Indoor Positioning and Navigation with Camera Phones.

The article discusses the design and trial deployments of indoor navigation with camera phones. The indoor navigation system associates locations with markers to offer a building orientation guide that relies on camera phones. A marker-based tracking suitability for continuous navigation in mobile phones has been examined through a controlled user study comparing system with a map without localization and with a global positioning system (GPS)-like real-time localization. Thus, the subjective experiences of users about ease of use and locate awareness have been evaluated.
