This paper reviews the usability of the Autopsy Forensic Browser. Two expert-based usability review techniques are used: Cognitive Walkthrough and Heuristic Evaluation. The results of the evaluation indicate that there are many areas where usability could be improved and these are classified into areas of eight overlapping areas. Examples from each area are presented, with suggestions as to met...

A ventilator system provides respiratory support to critically ill patients in the Intensive Care Unit. Increasing complexity in the user interface, features and functionalities of ventilator systems can cause medical errors and cost the life of a patient. Therefore, the usability of ventilator systems is most crucial to ensure patient safety. We have evolved a specialized set of heuristics com...

Heuristic forward search is the dominant approach to satisficing planning to date. Most successful planning systems, however, go beyond plain heuristic search by employing various search-enhancement techniques. One example is the use of helpful actions or preferred operators, providing information which may complement heuristic values. A second example is deferred heuristic evaluation, a search...

Web site redesign is a complex task that requires the organised use of design methods and guidelines as well as meaningful assessments. An important reason for web site redesign is to enhance the usability and accessibility for ‘non-traditional’ user groups like the older population. The paper presents a case study of the redesign of a touristic web portal in order for it to be senior-friendly....

Generally, universities have complex and large websites, which include a collection of many sub-sites related to the different parts of universities (e.g. registration unit, faculties, departments). Managers of academic institutions and educational websites need to know types of usability problems that could be found on their websites. This would shed the light on possible weak aspects on their...

We present the news wall ambient display designed for continuous exposure to news information. The display benefits the elderly and people with special needs as it maintains a prolonged contact with news information. Since the display is not interactive, it capitalizes on serendipity rather than user feedback to communicate interesting information. The display’s effectiveness depends on the fre...

In previous work we have shown that grounding, while used by most (if not all) modern state-of-the-art planners, is not necessary and is sometimes even undesirable. In this paper we extend this work and present a novel forward-chaining planner that does not require grounding and can solve problem instances that are too large for current planners to handle. We achieve this by exploiting equivale...

Heuristic evaluation relies fundamentally on predefined criteria to direct attention to important aspects of the inspected phenomenon, such as Jacob Nielsen’s ten usability heuristics. In this paper we present nine complementary principles explicitly focused on evaluation of IT-systems as tools for business action and communication. The principles are derived from the concept of actability, whi...

Critic-proofing is a modified heuristic evaluation technique, specifically designed to provide a fine-grained, prioritized list of heuristic violations. The critic-proofing technique weights the severity of a problem based on the frequency that similar problems are found in similar games. The severity ratings are calculated using data collected from game reviews, and the severity assigned to a ...

Along several years, Nokia has utilized user experience heuristics for assessing design prototypes with a panel of internal experts. In this paper, we describe how we have tailored the traditional heuristic evaluation method to suit the needs of a large multinational corporate. HEURISTIC EVALUATION Heuristic evaluation method [3] has traditionally been used for evaluating usability against a se...
