Handheld Augmented reality (AR) is the ability of smartphones to overlay digital information on a real view (video stream) of the world using built-in sensors such as, GPS, Compass and Accelerometer. With the use of geo-tagging and location based services, information is automatically filtered whenever users point their devices to places or objects of interest around them allowing them to "browse the world".
The next generation of world browsers promises a virtual world that end users can customize, share and describe in their own words and in their own way. They can do all this as they live in it, without being restricted to a desktop computer. User generated content will be integrated with geo-tagged social media and Web 2.0 services available through the programmable web. In this seminar, we will cover in depth the current solutions, challenges and possibilities for world browsers. Additionally, we will aim to explore the current research challenges of indoor browsing, mobile based labeling and collaborative filtering of contextual information for users.
