The Benefits of Combining Paper-and Video-Based Prototypes for User Interface Evaluation

Abstract : The use of multiple User Interface (UI) designs for evaluation has been demonstrated beneficial for UI evaluation as it results in better feedback, both qualitatively and quantitatively. However, producing several designs is time-consuming. Moreover, the properties that the alternative UI must satisfy remain under-explored. The paper investigates the use of different prototype forms of the same design as support to evaluation instead of relying on alternative design solutions. We investigate two experimental conditions: (1) paper prototype first then video prototype, and (2) video prototype first then paper prototype. Results show that the combination of paper and video prototypes is well suited for UI evaluation, as feedback addresses all aspects of Human-Computer Interaction (HCI), namely, utility, usability, and aesthetics. When exposed to multiple prototypes, users develop an understanding of the functional core and of the interactive aspect of the system. The experiment outcomes indicate that, when evaluating the paper prototype first, then the video prototype, users tend to be more critical and provide more suggestions of improvements.
