Impact of Interface Characteristics on the Perceived Ease of Use and Perceived Usefulness of Digital Library Adoption among Post-Graduate Students in Somalia

Abstract
The Main objective of this paper was to investigate the impact of interface characteristics—terminology and
screen design—on the perceived ease of use and perceived usefulness of digital libraries among post-graduate
students in Somalia. Convenient sampling method was adopted for sample selection and a structured
questionnaire was distributed on July, 2014. The study found out that terminology used on the digital library
interface has a positive influence on its perceived ease of use. Also, screen design has much impact on the
perceived ease of using digital library. Finally, a positive correlation between perceived ease of use and
perceived usefulness was found. These findings imply that some factors such as exclusion of technical terms and
jargons to enhance ease of use of digital libraries should be taken into consideration (when planning and building
digital libraries).
