We propose a new metaheuristic called heuristic concentration-integer (HCI). This metaheuristic is a modified version of the heuristic concentration (HC), oriented to find good solutions for a class of integer programming problems, composed by problems in which p elements must be selected from a larger set, and each element can be selected more than once. These problems are common in location a...

Implementation of machine learning (ML) in human-computer interaction (HCI) work is not trivial. This article reports on a survey of 112 professionals and academicians specializing in HCI, who were asked to state level of ML use in HCI work. Responses were captured via a structured questionnaire. Analysis showed that about one-third of those who participated in the survey had used ML in conjunc...

Most present HCI design patterns and pattern languages are based on the traditional user interfaces, i.e., the graphical user interfaces. However, with growing popularity of computers, user interfaces for HCI are being integrated in more and more application domains. Today, large amount of user interfaces go beyond the desktop metaphor, which results in complexity and diversity in user interfac...

Human-Computer Interaction (HCI) is the discipline concerned with the design, evaluation, and implementation of interactive computing systems. Typically, HCI researchers do not primarily study existing technologies, styles of interaction, or interface solutions. On the contrary, one of the core activities in contemporary HCI is to design new technologies—prototypes—that act as vehicles through ...

Human computer interaction (HC!) is a subject which software developers can ill afford to ignore, yet there is little evidence that software engineers HCl seriously. The paper sets out to describe the software engineering and HCI issues which have to be addressed, in a comparative framework of the development life cycle. From this the necessary conceptual models produced by specification method...

This chapter starts with an introduction illuminating the theoretical background necessary for taking culture into account in HCI design. Definitions of concepts used are provided followed by a historical overview on taking culture into account in HCI design. Subsequently, a glimpse of the current state of research in culture-centered HCI design is derived from secondary literature providing th...

The History of HCI is briefly reviewed together with three HCI models and structure including CSCW, CSCL and CSCR. It is shown that a number of authorities consider HCI to be a fragmented discipline with no agreed set of unifying design principles. An analysis of usability criteria based upon citation frequency of authors is performed in order to discover the eight most recognised HCI principles.

In this position paper, we argue that usable privacy and security is a grand challenge that needs more attention from the HCI community. We also discuss benefits to and new challenges for HCI, and use our research experiences to provide a critique of HCI. Usable Privacy and Security: A Grand Challenge for HCI Jason I.

HCI has borrowed some concepts from existential phenomenology, in particular Dreyfus’s interpretation of Heidegger’s philosophy. Not all concepts have been widely discussed, and it is urgently important to investigate further consequences of existential phenomenology on research and design of technology. ”Presence-at-hand” and ”readiness-at-hand” are two concepts that have been accomodated into...

Linked Environments for Atmospheric Discovery (LEAD) is a National Science Foundation (NSF) multidisciplinary project dedicated to designing a cyberinfrastructure (CI) for mesoscale meteorology. This paper considers how the fundamental structure and responsibilities of the project have complicated and delayed the inclusion of HumanComputer Interaction (HCI) design in the project. Through close ...
