User Authentication Based on Representative Users
IEEE Transactions on Systems, Man, and Cybernetics, Part C (Applications and Reviews), 2012User authentication based on username and password is the most common means to enforce access control. This form of access restriction is prone to hacking since stolen usernames and passwords can be exploited to impersonate legitimate users in order to commit malicious activity. Biometric authentication incorporates additional user characteristics such

Proceedings of the 2017 ACM Symposium on Document Engineering, 2017
Document engineering is all about building systems and tools that allow people to work with documents and document collections. A key aspect is the usefulness and usability of these tools. In this tutorial, we will look at the many different kinds of user studies and user evaluations that can be used to inform the design and improve utility and ...

User Property, User Rights, and User Privileges
2017This chapter proposes two principles that should inform the development of copyright law and policy and of user rights. The first calls for more cohesion between copyright law, private law, and public law, and for less exceptionalism in copyright law.

The proximity of users to user services
Proceedings of the 5th annual ACM SIGUCCS conference on User services - SIGUCCS '77, 1977The title of this paper is a purposeful misreading of a suggested topic that is designed to stress a major fact of CUNY/UCC life. The City University of New York consists of 21 individual units scattered throughout the five boroughs of New York City with a total constituency of 250,000 people.

User services and statistical users
Proceedings of the 5th annual ACM SIGUCCS conference on User services - SIGUCCS '77, 1977Universities, over the past decade, have seen a shift to empirical research in the social sciences, and to some extent, in the humanities. The origins of this trend are irrelevant here, but the refinement of statistical analysis packages in response to the new market has had a powerful impact on university computing centers. Computing has become a tool

The Framy user interface for visually-impaired users
2011 Sixth International Conference on Digital Information Management, 2011We have developed a multimodal interface; Framy to effectively display large 2-dimenetional data sets such as geographical data on a mobile interface. We have now extended this to be used by visually-impaired users. A pilot study that we conducted, and the interviews with a group of potential stakeholders, helped us to detect some critical problems ...

User Modelling to Support User Customization
2005The following describes ongoing doctoral research on creating a mixed-initiative framework to help users customize complex interfaces. The framework relies on a rich user model to provide customization suggestions with the goal of improving user performance while maintaining a high level of user satisfaction.

The attitudes of heroin users and matched non-users to drugs and drug users
Drug and Alcohol Dependence, 1991Compared with matched controls, heroin users were more tolerant of substance use and perceived themselves as slightly more unemployed, depressed, neat and aggressive. Both groups thought crack cocaine, heroin and alcohol dangerous. Heroin users were most in favour of cannabis, followed by controls who had used cannabis, with only controls who had never

Putting the user in user-interface testing
IEEE Software, 1996Discusses one of the most basic topics in user-interface design: how to run a user test. No matter how good we are at designing a user interface, we must always test it with real users to see whether it is as usable as we hope. The three main rules of user testing are: get real users, have them do real tasks, and shut up while they are trying.
