Laura Dabbish presented Carnegie Mellon's early research that resulted in the development of The ESP Game and Peekaboom. The ESP Game is a two-player game where both players are presented with an image. Then, the players need to guess the same keyword to describe the image. The problem with this game, however, is that it does not tell where the objects in the images are located. This is the issue that Peekaboom attempts to solve.

Peekaboom is also a two-player game. In this game, player X is presented with an image and a corresponding keyword. Player Y needs to guess the keyword. However, Player Y cannot see the image. Player X can uncover part of the image for Player Y by clicking on it. The outcome of this game identifies what part of an image corresponds to a particular keyword. The game is very popular and only supports the English language. Laura noted that users are using the game to help learn English, and are considering multiple languages for the game in the future.

Keith Wiley then presented his work on the Druid 2 1/2D imaging program. To make knots in convention programs (such as Photoshop or Illustrator), one needs to create a spoof. The problem is that these spoofs are often not scalable. In other words, if one changes one part of the image, one will have to do the spoof over again. Druid attempts to solve this problem and can be used to make very complex knots. The application of this technology is primarily in digital art.

The last two notes in this paper session were on other games from Carnegie Mellon University that solve problems not addressed by Peekaboom and The ESP Game. Verbosity is a two-player game that attempts to build a database of common knowledge/facts. The game is not yet live. Phetch is another product of CMU, attempting to solve the problem of the lack of ALT tags being used by web developers. Player X in Phetch types a paragraph describing an image, and Player Y needs to find the image using Phetch's image search.
