dc.description.abstractAs technologies for interacting with state-of-the-art specialised systems become more sophisticated, the need for novel mechanisms to interact with multiple elements simultaneously prompts for the development of various multidimensional input devices. Due to the wide range of input devices it is necessary to identify optimum tools for interaction in various environments. In this study we empirically evaluate SpaceCat softly elastic 6 DOF input device and examine its quality of use compared to SpaceNavigator’s stiffly elastic suspension. Such an experiment would give further clues on the usability of a universal softly elastic multidimensional input device compared to specialized input devices for navigation. Using a within-subjects design, evaluation of performance was done according to subjects’ progress in Forsaken 3D game. Usability properties of the input devices were further analyzed by assessing their particular aspects of physical operation, mental effort, accuracy and speed, fatigue and comfort, and overall usability through ISO 9241-9 standard questionnaire. Results from the analysis did not show a significant difference in performance scores for SpaceCat and SpaceNavigator. Consequently, there is no reason to conclude that for rate control, SpaceCat or SpaceNavigator outperform one another. Results from the analysis of subjective rankings were significant for the force required for navigation, smoothness of navigation, and navigation across Z-axis for moving forward in the game. According to our findings, SpaceCat is smoother to operate by demanding less force for performing navigational tasks and provides easier operation functions on Z-axis. As a result, we believe that SpaceCat can perform navigational tasks equally well compared to SpaceNavigator, while it provides smoother navigational experience.
