An Embedded Biometric Sensor for Ubiquitous Authentication
2013
Communication networks and distributed technologies move people towards the era of ubiquitous computing. An ubiquitous environment needs many authentication sensors for users recognition, in order to provide a secure infrastructure for both user access to resources and services and information management. Today the security requirements must ensure secure and trusted user information to protect sensitive data resource access and they could be used for user traceability inside the platform. Conventional authentication systems, based on username and password, are in crisis since they are not able to guarantee a suitable security level for several applications. Biometric authentication systems…
Supporting Relational Processing in Complex Animated Diagrams
2008
The psychological utility of different approaches to cueing key information within complex animated diagrams remains relatively unexplored. Because of the varied processing demands required to comprehend such representations, it is likely that providing a range of different cue types would be best for supporting effective user information extraction. Traditional cueing approaches used with static diagrams may need to be reconsidered in order to meet the new design challenges associated with their animated counterparts.
Research Directions of OLAP Personalizaton
2011
In this paper we have highlighted five existing approaches for introducing personalization in OLAP: preference constructors, dynamic personalization, visual OLAP, recommendations with user session analysis and recommendations with user profile analysis and have analyzed research papers within these directions. We have provided an evaluation in order to point out (i) personalization options, described in these approaches, and its applicability to OLAP schema elements, aggregate functions, OLAP operations, (ii) the type of constraints (hard, soft or other), used in each approach, (iii) the methods for obtaining user preferences and collecting user information. The goal of our paper is to syst…
Sociodemographic Characteristics and Interests of FeverApp Users
2021
The FeverApp Registry is a model registry focusing on pediatric fever using a mobile app to collect data and present recommendations. The recorded interactions can clarify the relationship between user documentation and user information. This initial evaluation regarding features of participants and usage intensity of educational video, information library, and documentation of fever events covers the runtime of FeverApp for the first 14 months. Of the 1592 users, the educational opening video was viewed by 41.5%, the Info Library was viewed by 37.5%, and fever events were documented by 55.5%. In the current sample, the role of a mother (p <
Latent Class Approach to Estimate the Willingness to Pay for Transit User Information
2012
The aim of analysis is to understand how unreliable information influences user behaviour and how much it discourages public transport use. For this purpose, a Stated Preference Survey was carried out in order to know the preferences of public transport users relating to information needs and uncertainty on the information provided by Advanced Traveller Information System (ATIS). The perceived uncertainty is defined as information inaccuracy. In our study, we consider- ed the difference between forecasted or scheduled waiting time at the bus stop and/or metro station provided by ATIS, and that experienced by user, to catch the bus and/or metro. A questionnaire was submitted to an appropriat…
Towards an Assessment of Public Library Value
2010
PurposeThis paper aims to present a methodology, early findings, possible applications of results and lessons learned from the research study “Public libraries: value, trust and satisfaction”, which has been conducted within the public library development project ‘Father's Third Son’ in Latvia.Design/methodology/approachA combination of quantitative and qualitative methods was used (although the findings reported here are largely drawn from the quantitative study) drawing on various theories of information behaviour and use‐oriented information service evaluation.FindingsThe study gives a good picture of user information needs in Latvia, the sources they use to fulfil them and the role of p…
