Seminar Description
The integrated sensors of smartphones, such as motion sensors or location sensors, make the device able to adopt new interaction techniques that enhances the usability on such handheld devices. However, despite their mobility and embedded sensor capacity, smartphones are limited in processing power and display area compared to desktop computer consoles. When it comes to evaluating Player Experience (PX), players might not have as compelling an experience because the rich graphics environment that a desktop computer can provide are absent on a smartphone. A plausible alternative in this regard can be substituting the virtual game world with the real world game board, perceived through the device camera by rendering the digital artifacts over the camera view. This technology is widely known as Augmented Reality (AR). The built-in sensors of smartphones (e.g. GPS, accelerometer, gyro-meter, compass) have enhanced the capability for deploying AR. Because AR play environments are viewed through the camera, rendering the digital artifacts consistently and accurately over view is crucial. In AR game environment, determining the pose of the camera in space is vital as the appropriate angle to view the rendered digital characters are determined by the pose of the camera. This defines how well the players will be able interact with the digital game characters. Depending in the Quality of Service (QoS) of these sensors, the Player Experience (PX) may vary as the rendering of digital characters are affected by noisy sensors causing a loss of registration. Confronting such problem while developing AR games is difficult in general as it requires creating wide variety of game types, narratives, input modalities as well as user-testing. Moreover, current AR games developers do not have any specific guidelines on these aspects.

The dissertation provides a complete view (a taxonomy) of the spatio-temporal sensor resolution dependency of the existing AR games followed by several controlled experiments to validate the taxonomy and demonstrate the differential impact of sensor noise on gameplay of different genres of AR games in different aspect of PX. Concrete guidelines are derived to regulate the sensor QoS as complete set of instructions to develop different genres or AR games.
