Percy is a small software framework for perception experiments via the WWW. It is implemented entirely in dynamic HTML and makes use of the new multimedia tags available in HTML5, eliminating the need for browser plug-ins or external players to display media content. With Percy, perception experiments can be run on any platform supporting HTML5, including tablet computers, smartphones or game consoles and thus access new participant populations.
Percy supports touch interfaces and measures reaction times. It stores its data in a relational database system on a server. This allows immediate access to the experiment data via standard database access APIs.
The system has been used for a number of experiments in German, Castilian Spanish and English.
