IntentStreams
2015
The user's understanding of information needs and the information available in the data collection can evolve during an exploratory search session. Search systems tailored for well-defined narrow search tasks may be suboptimal for exploratory search where the user can sequentially refine the expressions of her information needs and explore alternative search directions. A major challenge for exploratory search systems design is how to support such behavior and expose the user to relevant yet novel information that can be difficult to discover by using conventional query formulation techniques. We introduce IntentStreams, a system for exploratory search that provides interactive query refine…
Improving a traffic operator interface using an ontology and intelligent rules
2007
The Transportation and traffic domain is cross-disciplinary; Different areas must be covered to solve complex problems. It also involves the use of different systems for monitoring, visualization, information distribution, control, communication, etc. All of these systems are implemented using different levels of technology. In most cases the control of these systems is handled by [graphic] user interfaces. In the past years the number of systems has grown substantially and because of their "monolytic" design, they have different and in most cases not-compatible user-interfaces. A generic interface would be useful to improve not only the different processes but also the efficiency of the op…
Touchless Interfaces For Public Displays
2016
Public displays have lately become ubiquitous thanks to the decreasing cost of such technology and public policies supporting the development of smart cities. Depending on form factor, those displays might use touchless gestural interfaces that therefore are becoming more often the subject of public and private research. In this paper, we focus on touchless interactions with situated public displays, and introduce a pilot study on comparing two interfaces: an interface based on the Microsoft Human Interface Guidelines (HIG), a de facto standard in the field, and a novel interface, designed by us. Differently from the HIG-based one, our interface displays an avatar, which does not require an…
A framework for behavior-based detection of user substitution in a mobile context
2007
Personal mobile devices, such as mobile phones, smartphones, and communicators can be easily lost or stolen. Due to the functional abilities of these devices, their use by unintended persons may result in severe security breaches concerning private or corporate data and services. Organizations develop their security policy and employ preventive techniques to combat unauthorized use. Current solutions, however, are still breakable and there is a strong need for means to detect user substitution when it happens. A crucial issue in designing such means is to define the measures to be monitored. In this paper, a structured conceptual framework for mobile-user substitution detection is proposed.…
User-Centered Design for Biomedical Literature Search User Interfaces
2019
Biomedical literature search tools are crucial resources for the work of physicians, biologists, and bioinformatics. Many of the genetic-medical diagnoses depend on the findings in these literature resources. Despite the importance and value of the information stored in these resources, the user interface (UI) implemented by such tools present several usability problems converting the query and interpretation of the information into complex and time-consuming tasks. In this sense, an user-centered design (UCD) approach can improve the usability of these UIs facilitating the interaction, analysis, and comparison of biomedical information, and, consequently, improving the productivity of prac…
Lessons Learned from Implementing a Serious Game in Higher Education – A Student and Trainer Perspective
2020
Serious games (SGs) have shown great potential as student-active learning tools in education, as they enable experimentation with practice-related work environments and systems that may otherwise be challenging and/or impractical to facilitate in an educational institution. However, existing instructional design models are limited in use when it comes to how to implement and integrate SGs within the existing curricula. Furthermore, the trainer perspective is often neglected in literature about serious games. The aim of this study was to explore the experiences of both students and trainers after the implementation and use of a SG in a master level course in project management (PM). Data was…
Visualization and User Interface Questions about Disability
1999
The visually impaired and the intellectually disabled are not equal groups but both groups benefit partly from the same features. Communication, symbols, pictures, customizing and alternative languages are the key elements in visualization and in user interface design to the both groups.
The Logic of User Interface Design
2016
Technical artefacts exist so that people can use them to make something happen. Their capacity to do so depends on the functions and functionalities of the technology, which requires users. Technologies thus have to give users the ability to control them, and the designer’s role is to create the actions and work processes for which the artefacts are intended. This basic HTI pursuit is called user interface design. It applies technical interaction concepts to solve design problems. This chapter presents the overall principles and goals for the user interface design of any technical artefact.
XPL, a Presentation Language based on User Interface Design Pattern
2007
The great diversity of presentations in software applications deals with fulfillment of various type of graphic interface constructions related to different programming Languages. Moreover, in the Internet era html pages play a main role because of the increasing complexity of Web applications. In Software Engineering, the use of design patterns is proven remarkable for the design and reuse of software components. Visual Design. Patterns (ViDP) are useful to define interaction schemas between. user and computer. By the some token, visual design. patterns are useful to incorporate common interfaces of interaction, schemas between user and computer. This paper describes the eXtensible Present…
XPL and the Synchronization of Multimodal User Interfaces based on Design Pattern
2008
The great diversity of presentations in software applications deals with fulfilment of various types of user interface constructions related to different programming languages. Furthermore, the growing interest for multimodal applications entails that their user interfaces have to support multiple access channels within a single development framework. User Interfaces Design Patterns (UIDPs) are helpful to define interaction schemas between user and computer and they provide remarkable tools for the design and reuse of software components. This paper describes the eXtensible Presentation architecture and Language (XPL), a framework aimed at streamlining multi-channel interface design process…
