User Equilibrium with Length Constrained Users
2012 Fifth International Joint Conference on Computational Sciences and Optimization, 2012In this paper we introduce a length constrained user equilibrium model. In our model, people consider two criteria, path time and path length, when selecting their routes. They only travel on "acceptable paths", the paths whose length are not too long for them.

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 ...

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 ...
