This work was part of my MSc research at TU/e, supervised by Panos Markopoulos, a collaboration with Iris Soute

In this research we developed OPOS, an observation scheme for evaluating head-up games, a form of pervasive outdoor games. OPOS can be used to evaluate the similarities between digitally enhanced outdoor games and traditional outdoor games such as tag or hide-and-seek. OPOS was tested on a purpose built head-up game.

The concept of Head-Up Games advocates that pervasive games of the future should be designed to evoke play patterns akin to those of traditional outdoor games. This tenet, while appealing, is ill defined without a clear description of these behaviors. We developed OPOS, an observation scheme that can be used to evaluate Head-Up Games and, more generally, outdoor pervasive games intended for children. The observation scheme has been evaluated through its application in observing play with traditional outdoor games and a purpose made Head-Up Game. The study involved 24 children of 10-11 years old; it was found that the proposed observation scheme is objective and reliable, helping evaluators compare pervasive games regarding the play behaviors they provoke.
