Resumo

This study aims to assess whether gesture interaction can increase users' satisfaction in e-commerce sites for smartphones. Smartphones with touchscreens are being used more and more around the world and, among other possibilities, this type of device allows the gestural interaction, which implies the adoption of new practices for the interface design. In addition, in October 2013, the W3C published recommendations for the development of tactile applications for websites, suggesting that this category of interaction can be widely used for site development in the near future. Gesture interaction can give users more satisfaction as it enables a reduction of the visual overhead of the interface and can also make the interactions more natural. However, gesture interaction may present problems related to the discovery of interface possibilities and affordances. Among usability-related metrics, satisfaction is the one that is most related to trust in e-commerce, which is a very delicate element of this type of system, since the perceived risk in electronic transactions is generally high. Thus, satisfaction assessment was performed as a usability test with two prototypes of e-commerce sites, one using the traditional "touch" interaction and the other where it was applied to gesture interactions such as drag and drop and sliding. The test was applied to 20 undergraduate students in southern Brazil. The results suggest that in e-commerce sites for smartphones, users prefer the traditional touch interaction in gestural interaction.
