Perceived Usefulness of Learning Systems Due to Graphical User Interfaces Design

As web technology progresses, learning systems must keep up to maintain the interest of the demographics using these technologies, namely, young adults. Graphical user interfaces have become a staple in a successful piece of software. Web enabled learning systems have become very popular with today’s learning institutions who provide distance education alternatives to standard classroom education. These learning systems include a graphical user interface, which must be designed in a way that a student is engaged and perceives the material to be more interesting, leading to better understanding, and, in turn, higher grades. In this paper, it has been found that a well designed graphical user interface allows the student to perceive the learning system as more effective at displaying and manipulating content than the classical static web based text, image, and links layout.

An Evaluation of the Accessibility of School and School Board Websites in Ontario

Increasingly, the ability for people with disabilities to access online content is being recognized as a necessary consideration in website design, particularly for websites in the public sector. This paper investigates the current state of accessibility for school and school board websites in Ontario by evaluating their compliance with WCAG 2.0 AA standards using AChecker. While other studies have looked at post-secondary institutions and other public-sector domains, little research has been done on primary and secondary school websites. It was found that most of the websites examined did not comply with WCAG 2.0 AA, and that the three most common errors resulted from improper or missing alternate text for images, problems with making content distinguishable from the background, and navigation related issues, which is consistent with findings from other domains. Implementing better coding standards and practices, in combination with education of stakeholders would likely resolve many of these errors.

Safety-Focused User Adaptable User Interfaces

There are fields in which dependable, reliable and predictable systems are critical to safety. These safety-critical systems can be found in a variety of fields, such as in defence, aviation, medical and other fields that have control systems. Many of these systems are controlled through the use of human-control interfaces. However the interface design can lead to errors resulting in catastrophic consequences. Adaptable user interfaces are touted to be an improvement to fixed user interfaces, providing flexibility to user requiring or desiring a more customized experience which can result in greater productivity, reduction in errors, and an ability to make more timely and higher quality decisions. This video explains a methodology to design adaptable user interfaces for safety-focused environments.

A Goal Based HCI Design Framework with Goal Virtual Desktop UI to Support Multi-tasking and Interruption Handling and Recovery

Abstract: The interruption of people is a complex process and can negatively affect their performance [11]. Recovering from interruption often has a significant overhead cost, cognitive and manual [2, 4]. People have some natural ability to handle interruptions but need some control and interaction support [11]. If we can reduce the overheads during recovery, we can improve productivity.

There are not many complete solutions for helping people to handle and recover from interruptions. This paper proposes a complete frame work to effectively and efficiently handle interruption in order to minimize the negative effect on human performance of interruption during HCI. The propose framework addresses the issue from both human psychology and system design approaches.

This paper is structured into 5 sections. After an introduction to the research problem, the basic concept of interruption, its mechanism and handling techniques are discussed. The third section is a brief evaluation of two solutions proposed by other researchers followed by the description of the framework proposed by this paper. The fifth section is an evaluation of the proposed frame work followed by the conclusion.

Using User Interface Toolkits to Improve Human Computer Interaction in Medical Diagnostics

User interface toolkits are software aids used by developers to add to interface design. The libraries, connecting application programming interfaces (APIs) or even analysis tools allow developers to improve the human computer interaction (HCI) process in less development and resource time than they would if they were to design the interface from scratch.

In this video, we examine effectiveness of toolkits in collecting and analyzing patient data for various medical diagnostic objectives versus traditional development and the challenges and limitations with these toolkits. We evaluate a medical health analysis diagnostic service (MHADS) as an example of a user interface toolkit that would address some of these challenges and limitations. Using toolkits such as a statistical analysis tools and an integrated development environment (IDE) that includes web language libraries, the MHADS software demonstrates that user interface toolkits do indeed improve human computer interaction in medical diagnostics by reducing data collection, analysis and development time.
