User Research for Senior Users
2011The purpose of this research is to propose new user research method for senior users, and discover problems of user interface design, propose an idea for improvement using proposed method. Targeted user is senior user from middle 50s to late 60s, and targeted product is cellphone. The aim of proposed method is to find out more detailed problems and the

Users: Service Users and the Drug User Movement
2010In April 2006 a group of illegal drug user activists from around the world met at the 17th International Conference on the Reduction of Drug Related Harm in Vancouver, Canada. Together they produced a ‘statement about the international network of people who use drugs’, a document that is, in effect, an international declaration of drug users’ rights ...

Jointly positioning multiple users in aid of user-to-user distances
2017 IEEE 28th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2017A multiuser positioning algorithm in aid of user-to-user (U2U) distances is proposed in this paper. The cost function is the combination of non-linear least squares (NLS) of time of arrival (TOA) of multiple users and the NLS of U2U distances among users. Particle swarm optimization (PSO) is applied to search the best positions of the multiple users in

A User-Centered Approach to User Modeling [PDF]
, 1999 Generally, user modeling concerns a person interacting with a standing console. This scenario does not represent the Hyper Audio system in use: a visitor freely moves in a museum, gathering information from an adaptive and portable electronic guide. To provide designers with presumptive user behavior, data about visitor profiles and visit styles were ...

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.

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 ...

A Comparison of Marijuana Users and Non-users
Nature, 1970Interviews with sixty-two Americans in their twenties, mostly students, demonstrate that those who smoked marijuana moderately differed little in personality from those who did not indulge, but that heavy smokers of marijuana were rather less conventional. The smokers tended to drink little alcohol.

User cube: a taxonomy of end users
Communications of the ACM, 1989The user cube, a precise and comprehensive graphical taxonomy designed to provide a common base for understanding and classifying end users in organizations, can be used to assess the risks associated with end-user computing.

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

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.
