    Camera-based virtual environment interaction on mobile devices
    (Springer, 2006-11) Çapin, Tolga; Haro, A.; Setlur, V.; Wilkinson, S.
    Mobile virtual environments, with real-time 3D and 2D graphics, are now possible on smart phone and other camera-enabled devices. Using computer vision, the camera sensor can be treated as an input modality in applications by analyzing the incoming live video. We present our tracking algorithm and several mobile virtual environment and gaming prototypes including: a 3D first person shooter, a 2D puzzle game and a simple action game. Camera-based interaction provides a user experience that is not possible through traditional means, and maximizes the use of the limited display size. © Springer-Verlag Berlin Heidelberg 2006.

    Enhanced user performance in an image gallery application with a mobile autostereoscopic touch display
    (Elsevier, 2014) Sassi, A.; Pöyhönen P.; Jakonen, S.; Suomi, S.; Capin, T.; Häkkinen J.
    In this study, we explored how stereoscopic depth affects performance and user experience in a mobile device with an autostereoscopic touch display. Participants conducted a visual search task with an image gallery application on three layouts with different depth ranges. The task completion times were recorded, and the participants were asked to rate their experiences. The results revealed that the image search times were facilitated by a mild depth effect and that too great a depth slowed search times and decreased user-experience ratings. © 2014 Elsevier B.V.
