Usability in the development of packaging design: Complementing the subjective evaluation

Abstract

Nine different consumable products were evaluated: two packaging that already existed in the market; and nine prototypes developed as alternatives to those existing packaging. An SD protocol was applied with ten pairs of antagonistic adjectives; and a SUS protocol, with ten sentences for such products. Videos that showed the use process of each package and prototype were recorded. After watching the videos, participants answered the SD and SUS protocols. Results showed that the evaluation technique by SD and SUS, through videos, proved to be relevant. The prototypes that met aesthetic and functional requirements, and sought to minimize ergonomic issues, obtained expressive positive evaluations in both the SD and SUS protocols.
