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…
Usable Interface Design for Everyone
2011
En el diseño de "interfaces para todo el mundo" para los sistemas interactivos, es importante tener en cuenta factores como el costo, el mercado de destino, el estado del medio ambiente,etc. Los interfaces de usuario son fundamentales para el proceso de desarrollo de cualquier aplicación, y su diseño debe estar contemplado desde el principio. De las distintas partes de un sistema (hardware y software), es la interfaz el sistema que permite al usuario el acceso a los recursos informáticos. Los siete principios del "Diseño Universal" o "Diseño para Todos" se centran en un diseño utilizable universal, pero al mismo tiempo reconocer la influencia de factores internos y externos. Los cambios est…
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.…
Designing Touchless Gestural Interfaces for Public Displays
Nell’ultimo decennio, molti autori hanno studiato la possibilità di utilizzare le interfacce a gesti come strumento innovativo per supportare l’interazione con i computer. Inoltre, le recenti innovazioni tecnologiche hanno permesso di installare display interattivi in ambienti privati e pubblici. Tuttavia, l’interattività di tali display è spesso basata sull’uso di touchscreen, mentre tecnologie come i dispositivi Kinect-like vengono adottate molto più raramente, soprattutto se si considera l’ambito dei display pubblici. Al giorno d’oggi, l’opportunità di studiare le interfacce touchless per i display pubblici è diventata concreta, e rappresenta il campo di studio di diversi ricercatori. L’…
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…
Acoustic rendering of particle-based simulation of liquids in motion
2009
In interaction and interface design, the representation of continuous processes often uses liquid metaphors, such as dripping or streaming. When an auditory display of such processes is required, an approach to sound-synthesis based on the physics of liquids in motion would be the most convincing, especially when real-time interaction is into play. In order to bridge the complexity of fluid-dynamic simulations with the needs of interactive sonification, we propose a multi-rate sound synthesis of liquid phenomena. Low-rate smoothed-particle hydrodynamics is used to model liquids in motion and to trigger sound-emitting events. Such events, such as solid-liquid collision, or bubble formation, …
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.
