Prototyping methods comparison

The richness of feedback given by users during semi- structured interviews was compared in this project, using three prototyping methods. Three prototyping methods were used to communicate the concepts to the participants; a low-fidelity prototype video, storyboard with declarative images and an acting-out of the interaction with a paper prototype.

A total of 11 participants were interviewed after either been given a prototype video, storyboard or an acting-out with a paper prototype of the concept. The concept used in this study was the Skinput, an input device that projects an interface on the lower-arm and hand and measures the tapping location.

Although the number of participants was limited, it appears that the chosen method could result in a better understanding of the concepts after seeing a prototype video or an acting-out, compared to using a storyboard. What was also interesting was that storyboards and acting-out resulted in more technical questions about the concept, whereas in case of a video prototype participants did not focus on that. Last about the look-and-fool of the prototype it seems that after acting-out the prototype, participants gave much more elaborate suggestions how the prototype could be changed to make it more comfortable and wearable.
