What does preoperative three-dimensional image contribute to complex pancreatic surgery?
2020
Abstract The possibility of modelling diagnostic images in three dimensions (3D) in pancreatic surgery is a novelty that provides us multiple advantages. A better visualization of the structures allows us a more accurate planning of the surgical technique and makes it easier the surgery in complex cases. We present the case study of a borderline pancreatic head adenocarcinoma patient to illustrate the advantages of 3D modelling in complex pancreatic surgery. The help of 3D technology allowed us to optimally plan the intervention and facilitate surgical resection. The use of this tool could translate into: shorter operative time, fewer intraoperative complications or an increase in R0 resect…
Usability Challenges in Surgical Simulator Training
2009
Surgical virtual reality simulators have been taken into use in order to improve surgical skills training. Emergence of simulators increases the need for research and knowledge related to usability of medical simulators. In this study usability of laparoscopic surgical simulator was researched experimentally through combined analysis. Data was gathered with heuristic evaluation, questionnaires, and interviews as well as recorded simulator parameters. Results suggest that the surgical simulator could be more efficient learning and training tool if usability issues such as support and error prevention were reconsidered in more detail. There also seem to be grounds for connecting user support …
Adaptation of TECCU App Based on Patients´ Perceptions for the Telemonitoring of Inflammatory Bowel Disease: A Qualitative Study Using Focus Groups
2020
Background: Despite the continuous adaptation of eHealth systems for patients with inflammatory bowel disease (IBD), a significant disconnection persists between users and developers. Since non-adherence remains high, it is necessary to better understand the patients&rsquo
Revisiting corpus creation and analysis tools for translation tasks
2016
Many translation scholars have proposed the use of corpora to allow professional translators to produce high quality texts which read like originals. Yet, the diffusion of this methodology has been modest, one reason being the fact that software for corpora analyses have been developed with the linguist in mind, which means that they are generally complex and cumbersome, offering many advanced features, but lacking the level of usability and the specific features that meet translators’ needs. To overcome this shortcoming, we have developed TranslatorBank, a free corpus creation and analysis tool designed for translation tasks. TranslatorBank supports the creation of specialized monolingual …
Contribution of virtual reality to functional rehabilitation
2010
Virtual reality has grown immensely. Practical applications for the use of this technology encompass many fields in both engineering science and human science. In the field of medicine, one of the newest fields to benefit from the advances in VR technology, virtual reality has become a major new therapeutic tool not only in medicine and surgery but also for the treatment of psychological disorders and rehabilitation for impaired person. Our research presented in this thesis aims at developing utilities to aid in functional rehabilitation using virtual reality technology. The main research question of our work concerns the effect of virtual metaphors in learning and training human gestures f…
A DGS gesture dictionary for modelling on mobile devices
2017
ABSTRACTInteractive or Dynamic Geometry System (DGS) is a tool that help to teach and learn geometry using a computer-based interactive environment. Traditionally, the interaction with DGS is based on keyboard and mouse events where the functionalities are accessed using a menu of icons. Nevertheless, recent findings suggest that such a traditional model of interaction has a steep learning curve and is inadequate to develop DGS for devices with multi-touch screens. Thus, we propose a new interaction model for DGS based on a gesture dictionary which enables the construction and manipulation of geometric objects without the need of accessing a menu of icons. The dictionary is divided into thr…
Training and Deployment as a Basis for Usability Engineering of Mobile Systems
2008
Usability engineering of mobile systems challenges existing methods and raises new concerns. Usability evaluations are frequently described as a separate discipline and in many cases usability evaluations are separate activities within the design and development of systems. This paper presents a development project where training in and the deployment of a mobile system were used to identify usability problems. The project aimed to develop a mobile system to supporting information processes for workers on building sites. An iterative usability evaluation process was conducted the process was refined and validated using two action research projects. The approach of the research was user-cent…
Usability remote evaluation: METBA system
2012
Usability as well as accessibility is a key aspect in development of human-computer interaction. This paper presents the basis of usability evaluation methodology and reviews the methodology used in empirical studies of usability evaluation for disabled people. Finally, we present a solution (METBA) as a system for managing the information related to evaluation of human behavioral observation contents that is used for the registration and management of the information derived from remote usability evaluation which complements the methodology commonly used in this research area.
Filtering usability data with reference to behavior
2011
No company can stay in business without having a "useful" web presence. The question is how usefullnes can be achieved. Usefullnes in this sense is how attractive and useful it is for the visitors. This can be done by observing the visitors' behavior. Doing this through interviews and observation of users in their living rooms is expensive and in many cases even impractical. So, other means need to be found. This paper presents a tool for the evaluation of usefulness of a web presence by extracting and analyzing information out of its log files. The information extraction can be refined using a set of filters which can be arbitrarily combined by the usability engineer responsible for mainta…
Smart Technologies for the Environmental Design of Smaller Urban Centres
2020
The present study focuses on welfare measures and specifically on healthcare. The challenge we would like to accept is to provide efficient healthcare to residents in an isolated area without health services, maintaining the same level of healthcare ensured by hospitals. The innovative design, that we want to experience, is closely linked to the use of ICT, information and communication technologies, because these technologies would be able to perform autonomously multiple functions, using remote control. Telemedicine or “virtual health” is a particular branch of ICT that can improve future quality of living in a marginal urban center as a tool to ensure prompt access to expert advice, as w…
