An Evaluation of Game Controllers and Tablets as Controllers for Interactive TV Applications
There is a growing interest in bringing online and streaming content to the television. Gaming platforms such as the PS3, Xbox 360 and Wii are at the center of this digital convergence; platforms for accessing new media services. This presents a number of interface challenges, as controllers designed for gaming have to be adapted to accessing online content. We conducted a user study examining the limitations and affordances of novel game controllers in an interactive TV (iTV) context and compared them to "second display" approaches using tablets. We looked at task completion times, accuracy and user satisfaction across a number of tasks and found that the Wiimote is most liked and performed best in almost all tasks.

Participants found the Kinect difficult to use, which led to slow performance and high error rates. We discuss challenges and opportunities for the future convergence of game consoles and iTV. We also analyzed the usability of the interfaces themselves with respect to each device.  Accuracy ratings and context of task type were used to determine ideal component attributes such as button size and spacing. Additional strategies like snapping cursor to buttons in the case of small targets were also suggested. Paying attention to the strengths and weaknesses of each input method, we put forth a set of design recommendations for future iTV interfaces that leverage novel input devices.
