Merging virtual and real with handphones

I once saw a HP ad where a boy, armed with a handheld console with a camera, runs around a city playing a game on the handheld. The locations in the game correspond to the boy’s current real-world location, but with obstacles and challenges. So an innocent looking alley in the real world turns into a deathtrap in the game world, with a virtual boulder coming down towards you (like in Raiders of the Lost Ark)

I love the idea of blurring the lines between the real and the virtual, and I thought then: “why do you need a separate device? Almost everyone already carries a camera handphone these days.”

Wish some Singaporeans followed up on this idea before the Scots did.

“It’s about using a camera phone as a magic wand,” said Dr Mark Wright of the Division of Informatics at the University of Edinburgh who came up with the idea.

At the heart of Spellbinder, as the project is known, is a database of all the places that participants have added data to. People query it by taking a snap of a location with their phone then using multimedia text messages to send it to Spellbinder.

Dr Wright said powerful image-matching algorithms are used to analyse the image that can deal with snaps of the same place being taken under different lighting conditions or orientations.

Once Spellbinder has worked out the location of an image it consults the database and sends back an image with the extras added to it. (read full article)
