This paper presents results from a study on the effectiveness of digital signage in the retail environment. The goal of the study was to examine design parameters relevant to digital signage content design which could be used to create guidelines and templates for designing effective digital signage content. In this study, we focused on how video and animation affect the effectiveness of digital signage. When comparing still content with content enhanced with video or animation, no significant difference in effectiveness could be observed. This observation contradicts with earlier studies. Our study supports the views that the digital displays are currently most useful and effective to the younger generation, and that male customers consider digital displays in a store more useful than females do.
