Augmented Reality is one of the hottest trends in mobile media, yet there is a substantial lack of user studies within this field of research. The purpose of this study is to evaluate the value of mobile augmented reality as a vehicle for information delivery on the basis of a usability and design analysis. Using a multi-­dimensional qualitative method, this study examines the impressions of users and designers regarding mobile augmented reality, along with a heuristic evaluation of select mobile applications. This analysis finds that (1) users believe mobile augmented reality offers great promise as a medium for visual communication, and (2) it’s current execution is limited by technical restraints, design flaws and a lack of compelling content. It is concluded that mobile augmented reality will one day revolutionize how consumers engage geographical and time-basedinformation. Yet, like all new technologies, mobile augmented reality needs time to mature in order to address these limitations. Finally, based on the findings of this study, this thesis offers suggested guidelines for future developments in this medium. / Department of Telecommunications

The challenge of having to create and remember a secure password for each user account has become a problem for many computer users and can lead to bad password management practices. Simpler and less secure passwords are often selected and are regularly reused across multiple user accounts. Computer users within corporations and institutions are subject to password policies, policies which require users to create passwords of a specified length and composition and change passwords regularly. These policies often prevent users from reusing previous selected passwords. Security vendors and professionals have sought to improve or even replace password authentication. Technologies such as multi-factor authentication and single sign-on have been developed to complement or even replace password authentication. The objective of the study was to investigate the password habits of South African computer and internet users. The aim was to assess their attitudes toward password security, to determine whether password policies affect the manner in which they manage their passwords and to investigate their exposure to alternate authentication technologies. The results from the online survey demonstrated that password practices of the participants across their professional and personal contexts were generally insecure. Participants often used shorter, simpler and ultimately less secure passwords. Participants would try to memorise all of their passwords or reuse the same password on most of their accounts. Many participants had not received any security awareness training, and additional security technologies (such as multi-factor authentication or password managers) were seldom used or provided to them. The password policies encountered by the participants in their organisations did little towards encouraging the users to apply more secure password practices. Users lack the knowledge and understanding about password security as they had received little or no training pertaining to it.
