User Experience Design for E-Voting: How mental models align with security mechanisms

Abstract

This paper presents a mobile application for vote-casting and vote-verification based on the Selene e-voting protocol and explains how it was developed and implemented using the User Experience Design process. The resulting interface was tested with 38 participants, and user experience data was collected via questionnaires and semi-structured interviews on user experience and perceived security. Results concerning the impact of displaying security mechanisms on UX were presented in a complementary paper [7]. Here we expand on this analysis by studying the mental models revealed during the interviews and compare them with theoretical security notions. Finally, we propose a list of improvements for designs of future voting protocols.

A Mobile Based Pharmacy Store Location-aware System

“…System quality was delineated for the purpose of this evaluation as a system that assists users to find the location of drug availability. This was done to ensure that the user experience of users; that is their perceptions and responses, which resulted from their use of the system deliver the required services as prescribed in [36]. A total of eighty four (84) end users partook in the UET exercise.…”
