User Experiences and Satisfaction with an Electronic Health Record System
2019
Electronic health records have a crucial role for communication and information management in health care organizations. Electronic health records have improved the access to up-dated medical information at the point-of-care, but they have also been linked to usability issues and user problems. This paper presents a study about the user experience among health care professionals regarding an electronic health record system in Norway. Qualitative research methods were used, with interviews and observations made at a university hospital, where 14 clinical end-users of an electronic health record system contributed. The aim was to study the user experiences and the user satisfaction regarding …
Estimating web site readability using content extraction
2009
Nowadays, information is primarily searched on the WWW. From a user perspective, the readability is an important criterion for measuring the accessibility and thereby the quality of an information. We show that modern content extraction algorithms help to estimate the readability of a web document quite accurate.
Including functional usability features in a Model-Driven Development Method
2013
The Software Engineering (SE) community has historically focused on working with models to represent functionality and persistence, pushing interaction modelling into the background, which has been covered by the Human Computer Interaction (HCI) community. Recently, adequately modelling interaction, and specifically usability, is being considered as a key factor for success in user acceptance, making the integration of the SE and HCI communities more necessary. If we focus on the Model-Driven Development (MDD) paradigm, we notice that there is a lack of proposals to deal with usability features from the very first steps of software development process. In general, usability features are man…
Introducing Usability in a Conceptual Modeling-Based Software Development Process
2012
Usability plays an important role to satisfy users? needs. There are many recommendations in the HCI literature on how to improve software usability. Our research focuses on such recommendations that affect the system architecture rather than just the interface. However, improving software usability in aspects that affect architecture increases the analyst?s workload and development complexity. This paper proposes a solution based on model-driven development. We propose representing functional usability mechanisms abstractly by means of conceptual primitives. The analyst will use these primitives to incorporate functional usability features at the early stages of the development process. Fo…
An analysis of the scientific productivity and visibility of publications on usability (1971-2005)
2009
Aims: To analyse usability-related articles published in the period 1971-2005 from a bibliometric point of view. Methods: A search for articles was made in the CSIC databases, the Social Science Citation Index, Science Citation Index, PsycInfo, MEDLINE and Inspec databases, using ad hoc search strategies designed for each. Contribution, specific contribution and overlap indices were calculated, as were the indicators of change in scientific production, the productivity of institutions and journals, and the distribution of journals by area of knowledge. Results: An exponential increase in the number of published articles was recorded, with the highest increase seen over the last five years. …
Intelligence as a service : designing semantic APIs to intelligent software
2011
The purpose and focus of this Bachelor’s Thesis is to explore, examine and (to some extent) analyze the design heuristics and guidelines of an API that is to be implemented for a software or service that facilitates AI. An essential challenge in the creating of the thesis is that there are no papers to be found on the particular subject. General API design guidelines, related W3C recommendations and basic requirements of AI are explored, while trying to form some kind of a cohesion about what a semantic API for an intelligent software would or should be like.
eHealth-Extended Care Coordination: Development of a Collaborative System for Inter-municipal Dementia Teams: A Research Project with a User-Centered…
2015
- In Norway, a health reform was recently adopted to improve continuity of care. Services that were carried out in hospitals were transferred to municipalities. Small and medium size municipalities have established inter-municipal cooperation to provide specialized services across borders. The research project eHealth-extended Care Coordination studied the inter-municipal cooperation for assessment of dementia, identifying a need for improved communication and coordination. This paper presents the development process of a collaborative information system for dementia assessment using a user-centered design approach. Mixed methods, such as observations, semi-structured interviews and questio…
Wannier90 as a community code: new features and applications
2019
Wannier90 is an open-source computer program for calculating maximally-localised Wannier functions (MLWFs) from a set of Bloch states. It is interfaced to many widely used electronic-structure codes thanks to its independence from the basis sets representing these Bloch states. In the past few years the development of Wannier90 has transitioned to a community-driven model; this has resulted in a number of new developments that have been recently released in Wannier90 v3.0. In this article we describe these new functionalities, that include the implementation of new features for wannierisation and disentanglement (symmetry-adapted Wannier functions, selectively-localised Wannier functions, s…
A VR/AR Environment for Multi-User Liver Anatomy Education
2021
We present a Virtual and Augmented Reality multi-user prototype of a learning environment for liver anatomy education. Our system supports various training scenarios ranging from small learning groups to classroom-size education, where students and teachers can participate in virtual reality, augmented reality, or via desktop PCs. In an iterative development process with surgeons and teachers, a virtual organ library was created. Nineteen liver data sets were used comprising 3D surface models, 2D image data, pathology information, diagnosis and treatment decisions. These data sets can interactively be sorted and investigated individually regarding their volumetric and meta information. The …
Vectofocimetry: Dioptric power measurement in manual focimeters using power vectors
2021
Abstract Dioptric power measurement is classically achieved using manual focimeters. In this contribution, we present vectofocimetry as a novel methodology to be easily implemented in manual focimeters for improving their capabilities regarding dioptric power measurement. The new procedure is conceptually based on power vector formalism of dioptric power which represents the dioptric power as three values in the form of [M, J0, J45], it uses an iterative process of blur reduction, and it only requires a few modifications in the device that are easy-to-adapt and cost-effective. As a result, dioptric power measurements are easily and quickly obtained with comparable results to the reported on…
