Context. Gestural interfaces involves the ability of technology identifying and recognizing human body language and then interpret this into commands. This is usually used to ease our everyday life, but also to increase usability in for example mobile phones. Objectives. In this study the use of a gestural interface is evaluated as an interaction method to facilitate the introduction of new and novice users to 3D modeling tools. A gestural interface might reduce the modeling time without making an impact on the quality of the result. Methods. A gestural interface is designed and implemented based on previous research regarding gestural interfaces. Time and quality results are gathered through an experiment where participants are to complete a set of tasks in the modeling tool Autodesk Maya that relates to modeling. These tasks are executed in both the implemented gestural interfaces as well as the standard interface of Autodesk Maya. User experience is also gathered through the use of a SUS questionnaire. Results. 17 participants took part in the experiment. Each participant generated time and quality results for each task of the experiment for each interface. For each interface the user experience was recorded through a SUS questionnaire. Conclusions. The results showed that the use of a gestural interface did increase the modeling time for the users, indicating that the use of a gestural interface was not preferable as an interaction medium. The results did show that the time difference between the interfaces was reduced for each completed task, indicating that the gestural interface might have an increase in learnability of the software. The same indication were given from the SUS questionnaire. Also, the results did not show any impact on the quality.
