Radiomics-guided prediction of overall survival (OS) in brain gliomas is seen as a significant problem in Neuro-oncology. The ultimate goal is to develop a robust MRI-based approach (i.e., a radiomics model) that can accurately classify a novel subject as a short-term survivor, a medium-term survivor, or a long-term survivor. The BraTS 2020 challen...
In this paper, we explored predictive performance of region-specific radiomic models for overall survival classification task in BraTS 2019 dataset. We independently trained three radiomic models: single-region model which included radiomic features from whole tumor (WT) region only, 3-subregions model which included radiomic features from non-enha...
Introduction:
Smartphone-delivered healthcare interventions allow patients to access services on demand when needed, improving motivation and compliance. However, the use of mobile health apps has been scarcely explored in sexual medicine.
Aim:
To evaluate the effects of integrating psychological treatment for premature ejaculation (PE) with a m...
The computational capabilities of today’s smartphones make it possible to take advantage of mobile three-dimensional (3-D) maps to support navigation in the physical world. In particular, 3-D maps might be useful to facilitate indoor wayfinding in large and complex buildings, where the typical orientation cues (e.g., street names) and location trac...
Background and objective:
Human motor skills or impairments have been traditionally assessed by neurologists by means of paper-and-pencil tests or special hardware. More recently, technologies such as digitizing tablets and touchscreens have offered neurologists new assessment possibilities, but their use has been restricted to a specific medical...
Printed maps are the most common tool to prepare people for emergency evacuation in contexts such as public buildings or transportation. Unfortunately, they are poorly understood and often ignored by people. Virtual environments (VEs) could be a more effective method to support people in acquiring spatial knowledge about the real-world environment...
The International Agency for Research on Cancer classifies radiofrequency (RF) electromagnetic emissions of cell phones as possibly carcinogenic to humans [1] and suggests the use of hands-free devices such as earphones to reduce direct exposure of the brain to such emissions. In this paper, we present the design of a mobile application that exploi...
Overview+Detail visualization is one of the major approaches to the display of large information spaces on a computer screen. Widely used in desktop applications, its feasibility on mobile devices has been scarcely investigated. This paper first provides a detailed analysis of the literature on Overview+Detail visualization, discussing and comparin...
Overview+Detail and Wedge have been proposed in the literature as effective approaches to resolve the off-screen objects problem on mobile devices. However, they have been studied with a small number of off-screen objects and (in most studies) with static scenarios, in which users did not have to perform any navigation activity. In this paper, we p...

Mobile technologies may be helpful to support students with
disability in navigating buildings and accessing useful services in higher
education facilities. However, the design of appropriate mobile solutions
depends on knowledge of the actual needs of disabled students, and is
made di�cult by the lack of contributions in the literature about the
p...
GPS-based pedestrian navigation can be difficult when GPS position readings are inaccurate or unavailable. In this paper, we report on a user study we carried out to investigate whether different visualizations of the uncertainty associated to user position can help users navigate outdoors when the GPS signal is degraded. In the study, we compared...
When navigating large information spaces on mobile devices, the small size of the display often causes relevant content to shift off-screen, greatly increasing the difficulty of spatial tasks such as planning routes or finding points of interest on a map. Two possible approaches to mitigate the problem are Contextual Cues, i.e. visualizing abstract...
In this paper, we present MoStarD, a mobile application that couples starfield displays with dynamic queries to support user exploration of large datasets. A novel space compression technique enables users to compress areas of the starfield display to optimize screen space usage and easily focus on specific subsets of a dataset.
This paper presents a study comparing two Zoomable User Interfaces with Overviews (ZUIOs) against a classic Zoomable User Interface (ZUI) in the context of user navigation of large information spaces on mobile devices. The study aims at exploring (i) if an overview is worth the space it uses as an orientation tool during navigation of an informatio...
In this chapter, we will deal with cluttering issues associated with the
visualization of a high number of icons, representing Points of Interest, on mobile
maps. Clutter is a frequently occuring problem that makes it difficult to understand
the visualization and has the even more critical effect of masking data.
As the user zooms out, the position...
Several techniques have been proposed to support user navigation of large information spaces (e.g., maps or web pages) on small-screen devices such as PDAs and Smartphones. In this paper, we present the results of an evaluation that compared three of these techniques to determine how they might affect performance and satisfaction of users. Two of t...
The capabilities of current mobile devices, especially PDAs, are making it possible to design and develop mobile applications that employ visual techniques for using geographic data in the field. These applications can be extremely useful in areas as diverse as tourism, business, natural resources management and homeland security. In this paper, we...
In this paper, we propose interactive visual analysis as a means to study user browsing of information spaces such as maps or web pages on mobile devices. In particular, we propose a set of specific interactive visualizations that can augment the insights usually obtained with experimental evaluations on users. As a practical example, we will illus...
This paper deals with the Mobile Browsing Explorer (Mobrex) to give analysts a set of interactive visualizations that highlight various aspects of how users browse an information space. Here, we describe the tool and demonstrate its support of a user study of three browsing techniques for mobile maps. Although we mainly focus here on PDAs and mobil...
In this paper, we describe the results of an experimental study whose objective was twofold: (1) comparing three navigation aids that help users perform wayfinding tasks in desktop virtual environments (VEs) by pointing out the location of objects or places; (2) evaluating the effects of user experience with 3D desktop VEs on their effectiveness wi...
Users who operate in the field (e.g., maintenance personnel, geologists, archaeologists, tourists, first responders) bring often with them paper sheets (e.g., city maps, forms, technical plans, object descriptions) containing data needed for their activities. Even when this data is available in digital form, the ...
Browsing large information spaces such as maps on the limited screen of mobile devices often requires people to perform panning and zooming operations that move relevant display content off- screen. This makes it difficult to perform spatial tasks such as finding the location of Points Of Interest (POIs) in a city. Visualizing the location of off-s...
The capabilities of current mobile computing devices such as PDAs and mobile phones are making it possible to design and develop mobile GIS applications that provide users with geographic data management and cartographic presentations in the field. However, research on how to properly support users who interact with geographic data on mobile device...
This paper discusses the design and development of a preference-based search tool (PBST) for tourists, operating on PDA devices. PBSTs are decision support systems that help users in finding the outcomes (e.g., multi-attribute products or services) that best satisfy their needs and preferences. Our tool is specifically aimed at filtering the amount...
Supporting users' navigation is a fundamental feature of mobile guides. This paper presents an experimental evaluation comparing three different ways of providing navigation guidance by combining visual and audio directions during guided city tours. The three considered solutions differ in the way audio directions are augmented with visual directio...
In this paper, we present LAMP3D, a system for the location-aware presentation of VRML content on mobile devices. We explore the application of LAMP3D in tourist mobile guides: the system is used to provide tourists with a D visualization of the environment they are exploring, synchronized with the physical world through the use of GPS data; touris...
In this paper, we present an approach to the selection of tourist information on a mobile device which could be usefully applied in the context of location-aware mobile guides and which is based on two specific aspects: supporting users' navigation by providing them with a 3D representation of the area they are exploring and allowing users to easil...
The navigation support provided by user interfaces of Virtual Environments (VEs) is often inadequate and tends to be overly complex, especially in the case of large-scale VEs. In this paper, we propose a novel navigation aid that aims at allowing users to easily locate objects and places inside large-scale VEs. The aid exploits 3D arrows to point t...
The worldwide popularisation of mobile communication technologies and the increas-ing awareness of usability issues since 1990's have been urging map designers to spe-cialise and extend cartographic semiotics, visualisation styles and map use techniques for mobile contexts and small display devices. As a follow-up to the first book "Map-based Mobil...
