Semantic tagging of images has a broad spectrum of applications, of both scientific and commercial interest. Experience has indicated that designing the interaction with human taggers in the form of a web game can be a very effective way to collect valuable tagged data. So far, implementations of such games have depended on explicit, deliberate input by the users. A novel alternative is presented that doesn’t only use signals from mouse and keyboard, but also utilizes brain activity data in the form of electroencephalography (EEG) scans. Brain response data from an earlier experiment [1] is analyzed in an attempt to find and evaluate a measure of similarity between responses of two subjects, suitable for use in a game. From the perspective of the test subjects, depending on the characteristics of the proposed game and the target audience, such a game could spark their interest in a computational approach to cognitive science.
