This paper presents a case study regarding the usability evaluation of navigation tasks by people with intellectual disabilities. The aim was to investigate the factors affecting usability, by comparing their user-Web interactions and underline the difficulties observed. For that purpose, two distinct study phases were performed: the first consisted in ...

Novel input modalities such as touch, tangibles or gestures try to exploit human's innate skills rather than imposing new learning processes. However, no work has been reported that systematically evaluates how these interfaces influence users' performance, that is, assesses if one interface can be more or less appropriate for interaction ...

With this study we intent to better understand how a group with intellectual disabilities interacts with digital content, namely web content, when performing equivalent tasks from their daily school activities, such as: painting, making puzzles, playing games. To accomplish this we observed how a group with intellectual disabilities, without experience ...

The recent advances made in human-computer interaction have allowed us to manipulate digital contents exploiting recognition-based technologies. However, no work has been reported that evaluates how these interfaces influence the performance of different user groups. With the appearance of multiple sensors and controllers for hand gesture recognition, it becomes important ...

In recent years there has been a boom of different natural interaction paradigms, such as touch, tangible or gesture-based interfaces, that make better use of human's innate skills rather than imposing new learning processes. However, no work has been reported that systematically evaluates how these interfaces influence users' performance with ...

Despite being a recent phenomenon and being in constant evolution, e-commerce EC is already embedded in current society. However, difficulties in establishing a universally accepted definition have resulted in a multiplicity of meanings that sometimes merge with the e-business EB concept. This article presents a brief historical and conceptual evolution ...

In the last decade, Synthetic Aperture Radar Interferometry (InSAR) has become operational as a technique that allows remote detection of deformation at the Earth's surface. Analysis of time series of SAR images extends the area where InSAR can be successfully applied and also permits detection of smaller displacements through the ...

In the last few years, the number of projects involving historical reconstruction has increased significantly. Recent technologies have proven a powerful tool for a better understanding of our cultural heritage through which to attain a glimpse of the environments in which our ancestors lived. However, to accomplish such a purpose, ...

Publisher: Eurographics Association
Bibliometrics:
Citation Count: 0

The virtual reconstruction of heritage sites has been the focus of many projects. These typically involve significant use of manual reconstruction techniques, and thus a great deal of human effort to create the virtual structures. Also, often, there is not sufficient physical evidence to recreate these structures precisely as they ...

The Human Visual System has a remarkable ability to acquire colour and contrast of all the things that surround us. This is particularly evident in extreme lighting conditions such as bright light or dark environments. However, it is simply not possible to represent such a range of lighting on a ...
