This paper presents the motivation, design, and pilot evaluation of CountMeIn, a pervasive collaborative game to improve the waiting time experience (e.g., waiting for a train, or traffic light to turn green). We tested two versions of CountMeIn, an NFC-based and touchscreen version in a small pilot study. Our early results showed that the NFC-based version increases collaboration, and was overall more positively perceived than the touchscreen version. We discuss the challenges ahead in deploying CountMeIn in a real-world setting.
