Physical-virtual linkage with contextual bookmarks

In our everyday life we often see objects or persons and are aware that there are related digital services such as an online ticket service when seeing a poster advertising a concert. Currently it is a rather time consuming activity to find the related information. Using our Contextual Bookmark system a user can define a snapshot with her mobile phone consisting of a picture, time stamp and location. Such a bookmark can then be stored on the mobile phone, exchanged with friends and in particular be used to access related videos, web pages, and other services. This helps the user to bridge the gap between the virtual and the real world in order to use related services. Combining content and context analysis objects are recognized without any visual markers or electronic tags. We would like to demonstrate our system based on a nomadic usage scenario in which a person defines a Contextual Bookmark of a movie trailer, buys the corresponding movie, plays the movie on a TV, and exchanges the bookmark with a friend.
