Google Scholar recently added the ability to find related articles for a paper, so I decided to try it out with a paper from my former life as a graphics person. It was a paper in SIGGRAPH a few years ago called the “Office of the Future” and it dealt with projecting images onto surfaces that aren’t exactly flat. If you predistort an image before you project it, you can often cancel out the different surfaces as you project onto them, which lets you create the appearance of a flat screen again.
Here’s a picture that gives you the idea. It’s completely unrelated to me or the paper, but it demonstrates the concept really well (I just did a flickr search for [projection surface] and found a nice result–thanks flickr!
I don’t read German, other than a few choice words like Private Krankenversicherung, Flugkarten, and parkplatz but it looks quite similar: someone is measuring the irregularity of the rock and then pre-distorting the projected image so that it looks flat when projected.
Anyway, back on topic. If you search for [office of the future] on Google Scholar, you get a page like this:
Cool, 300+ citations! Not bad. Now click on the “Related Articles” link and you see something like this:
I can attest that that’s a pretty relevant list of related articles.
One fun thing about working at Google is talking to different people. When I talk to grad students, a lot of them mention that they like Google Scholar, and I can understand why. If you’re looking for background research, Google Scholar is pretty helpful, especially with the new related articles feature. In the image above, for example, you can see the “CAVE” paper (4th one from the top) has 1026 citations. That’s a pretty seminal paper in the “projecting graphics on unusual displays” niche. Nice job making Scholar even better, A and A and whoever else worked on this.
