Enjoy losing at pool? Well the folks at Queen’s University just made it a whole lot easier. The Deep Green robot was created with the purpose of playing a flawless game, allowing it to beat even the most skilled human players. More than a couple of research papers have been written on the project. A ceiling-mounted Canon 350D tracks the position of all of the balls, in addition to another cue-mounted cam (for higher shot accuracy). Using a bunch of calculations, and a computer (probably more advanced than an Arduino), the Deep Green is able to strategize and play. Very well.
On a positive note, another team from Queens is working on a seperate but related project: ARpool (as in augmented reality). It was created to make playing pool easier. The website does not provide much info, but it seems to project different moves onto the pool table, allowing an inexperienced player to tell whether a shot is at all possible.
[onezerothrice] has been working hard on creating ARtisan, a flash library for bringing augmented reality to the browser. His goal in creating the library was to make AR projects quicker and easier to develop. The library can provide the location, size, and rotation of multiple markers on screen with little work from the developer. It is licensed under the GPL and comes bundled with Papervision3D, another flash library for manipulating objects in 3 dimensions. He has posted several demos with source and accompanying video.
Embedded above is a neat augmented reality business card by ActionScript developer [James Alliban]. After seeing “the most impressive business card you will ever see“, he was inspired to update his own business card. His new card has a fiduciary marker on the backside and directs you to his site. A flash app on the site displays a video where he tells you more about himself. The 3D grid of planes in the video varies in depth based on the brightness of the section. He has a few more AR and tracking demos on Vimeo.
Here’s a quick demo that FAT’s [Theo Watson] put together. It uses the iPod’s accelerometer to measure how fast it’s spinning and plays the sound file accordingly. This only works on the iPod touch 2nd gen because of its curved case. He says scratching is coming next, but currently the app doesn’t know which direction it’s spinning since it’s measuring outward force. This project was done in response to [vanderlin]’s AR scratching that used fiducials on records.
Digital Pictures Interactive has put together a great augmented reality demo. Unlike many others, it’s entirely Flash based, so there’s no install necessary. Print out the custom symbol and try it out for yourself in your browser. Augmented reality refers to any mashup that combines computer generated content with a live video stream. We see great potential for this technology and the large number of consumer webcams would certainly help consumer adoption. Video demo embedded below. Read the rest of this entry »
