Reading #26: Picturephone: A Game for Sketch Data Capture (Johnson)

Comments

Summary

This is a more detailed and particular description of the PicturePhone game described in reading #24. The Picturephone game consist of 4 consecutive steps

  • Player A is given a text description, and must make a drawing that captures that description as accurately as possible.
  • Player B receives the drawing and describes it in words.
  • Player C is given Player B’s description and draws it.
  • An unrelated player Player D is asked to judge how closely Player A and C’s drawings match, which assigns a score to players A, B, and C.

This enables to collect information on both word to sketch interpretation and also from sketch to words. The implementation allows researchers to use the collected data for their purposes such as training recognizers.

Discussion

Whooop! Short paper! However short, it gets to the point and accurately describes the application. The picturephone game is slower than Pictionary-like games, this can make it boring and not as fun. However it may report more reliable labels as they reward the accuracy of the picture and the descriptions. It serves as a nice compliment to the user that enjoys this type of low paced games.

  1. After reading the paper, still I dont get it what is the actual contribution of this work to sketch recognition????

  2. I agree with Sam. The contribution may be the tranfer from user study to game-based data collection? I think the idea is good that collecting data by games, but there is still a long way to use these data. So the idea is good but not practical. I prefer to use SOUSA instead of it.
