Imagine these scenario : You have just been from a trip to New York and have shared pictures on Flickr. One of the pics is of a burger shop that you loved and want to share the same with your friends on Flickr. It is normal for people to write such things on the image description area.
However, Yahoo has a better plan. In a patent filed by the company, the inventors explain the concept of a “virtual note” that can be overlaid across pictures that you have taken so that description of places captured in a photo as well as subsequent comments can happen inside the photo itself.
This is not all. The inventors talk of more embodiments. With geotagging already possible on Flickr, users may also browse across such virtual notes from a map view.
However, the most significant aspect of the invention is the use of augmented reality. The inventors describe that since these virtual notes are geotagged, accessing the service from a mobile device will gather all virtual notes geotagged to locations within a particular radius from the location of the mobile device that can be displayed to the user.
There appear to be a variety of use-cases to such an invention. Primarily this can simply serve as a tagging tool for Flickr users. However, such a tool can also grow to be a local-review feature (like Yelp?)where user reviews of places within localities can be accessed at a press of a button. And the worst use-case of all?Advertisers can use the virtual note feature to promote their places to people in the vicinity; much like Google’s ads on maps.
