Based on pre-tests with expert users we defined criteria for testing and found out about the preferences for handles of input devices. For this trial period we designed a new set of functional prototypes for magnetic tracking. Having taken the views of expert users into consideration, a controlled experiment was then conducted with novice users to compare the usability of an existing and a new device. Based on the results of this experiment we defined criteria to design input devices for immersive systems. A second controlled experiment was carried out to evaluate the revised device regarding its general design and the proposed design criteria. In this paper we will give a detailed presentation of the results of this experiment. From the results of this experiment we conclude that most of the applied design criteria have led to an i mproved input device.enconference paper
