Poster: Amplitude test for input devices for system control in immersive virtual environment

In this study, the amplitudes best suited to compare four input devices are examined in the context of a pointer-based system control interface for immersive virtual environments. The interfaces are based on a pen and tablet, a touch tablet, hand-tracking using Kinect and a Wii Nunchuk analog stick. This is done as a preliminary study in order to be able to compare the interfaces with the goal of evaluating them in the context of using virtual environments in a class lecture. Five amplitudes are tested for each of the four interfaces by having test participants mark menu elements in an eight-part radial menu using each combination of amplitude and interface. The amplitudes to be used for future experiments were found. Also, the movement times for the interfaces do not fit the predictions of Fitts´ law.
