To investigate the topic of intuitive interaction using a 3D-device, a toy car was used as a controller with the Stylaero Board to complete one lap in a car racing game. 20 participants completed the task in 2 conditions, one using the 3D-device as a controller, and one using a standard computer keyboard. The interaction was evaluated using task completion time as a measure of learnability of the device, as well as through subjective reactions from users gathered from a tailored questionnaire with 7 statements rated on a Likert scale of 1-5, and 3 open-ended questions. The performance and attitude towards the 3D-device as a controller was compared to the performance and attitude towards using a standard keyboard. The mean task completion time was significantly lower when using the keyboard. A subscale of the enjoyability of using the device was compared between conditions indicating a significant difference where the 3D-device was rated higher than the keyboard. Furthermore, a significant correlation was found between attitude towards the control device and task completion time in the keyboard, while no significant correlation was found between the corresponding variables for the 3D-device. These results indicate a difference between what aspects are important to users when evaluating a new interface compared to a familiar one. The subjective reactions gathered from the open-ended questions were categorized and sorted into themes using thematic analysis to illustrate the various aspects that were highlighted by users for each interface. The problems faced by participants when using the 3D-device were observed and analyzed in relation to current theories of intuitive interaction to find the driving factors of interaction with a new device.
