This paper discusses the challenges of studying affective interactions and reviews a pilot study designed to test the feasibility of studying the concurrence of facial and bodily expression. The study had three goals. First, evaluate the use of our emotion elicitation method. Second, determine if a specialized head mount for a face camera worn by participants interfered with performance. Third,...

Requirements elicitation is widely regarded as the most challenging activity within the scope of requirements engineering. The activity concerns the understanding of problems that a system should address, which later leads to the identification of system requirements. As an abstract process, its effectiveness is greatly influenced by the credibility and suitability of the stakeholders involved....

This paper presents the Group Elicitation Method (GEM), a brainwriting technique augmented by a decision support system for constructing a shared memory. GEM has been successfully used in four industrial projects to elicit knowledge from experts. In particular, in three of them it was used to elicit end-users' knowledge for the design of new knowledge-based user interfaces. An example is develo...

During the stage of system requirements gathering, model elicitation is aimed at identifying in textual scenarios model elements that are relevant for building a first version of models that will be further exploited in a model-driven engineering method. When multiple elements should be identified from multiple interrelated conceptual models, the complexity increases. Three method levels are su...

background: to extract utility values of diabetic retinopathy on a perfect health and perfect vision scales for iranians with both types diabetes. methods: in this investigation, 150 untreated patients with diabetic retinopathy consecutively were examined and interviewed in farabi eye hospital, tehran, iran, a tertiary referral center in the iranian health care system. utility values based on p...

Requirements elicitation is a key and critical activity for software/system development success. Several methods and techniques have been developed and used for requirements elicitation. Prior research referred to many problems and shortfalls with existing group-based methods (e.g., brainstorming, focus groups, and joint application development [JAD]). This paper provides a new approach for req...

Software requirements elicitation is a difficult process with many existing problems, and no single elicitation method solves all these problems. We introduce a new way of looking at the requirements elicitation process. Our model shows the requirements elicitation problem as a process of merging the users’ wants and the users’ needs into the same entity. In the context of our model, existing p...

Footrot is a widespread, infectious cause of lameness in sheep, with major economic and welfare costs. The aims of this research were: (i) to quantify how veterinary surgeons' beliefs regarding the efficacy of two treatments for footrot changed following a review of the evidence (ii) to obtain a consensus opinion following group discussions (iii) to capture complementary qualitative data to pla...
