Emotions in human-computer interaction: the role of nonverbal behaviour in interactive systems

Until recently, the area of human-computer interaction was based on a traditional, cognitive approach, which separated the study of usability from that of emotions. The recent research has shown that emotions play an important role in our life, which led to focusing on the need of studying the emotions in the domain of interactive design. This paper underlines the role of emotions as part of the interactive human-computer process, reinstating the importance of nonverbal communication in this domain. The main issues of this paper are concerned with aspects such as: emotional design approach, the importance of nonverbal as an instrument of usability evaluation and the role of emotions in human-computer interaction.Emotional design approach, nonverbal communication, emotions, usability, Human-Computer Interaction (HCI)

Software for Wearable Devices: Challenges and Opportunities

Wearable devices are a new form of mobile computer system that provides exclusive and user-personalized services. Wearable devices bring new issues and challenges to computer science and technology. This paper summarizes the development process and the categories of wearable devices. In addition, we present new key issues arising in aspects of wearable devices, including operating systems, database management system, network communication protocol, application development platform, privacy and security, energy consumption, human-computer interaction, software engineering, and big data.Comment: 6 pages, 1 figure, for Compsac 201

Dimensional Affect and Expression in Natural and Mediated Interaction

There is a perceived controversy as to whether the cognitive representation of affect is better modelled using a dimensional or categorical theory. This paper first suggests that these views are, in fact, compatible. The paper then discusses this theme and related issues in reference to a commonly stated application domain of research on human affect and expression: human computer interaction (HCI). The novel suggestion here is that a more realistic framing of studies of human affect in expression with reference to HCI and, particularly HCHI (Human-Computer-Human Interaction) entails some re-formulation of the approach to the basic phenomena themselves. This theme is illustrated with several examples from several recent research projects.Comment: Invited article presented at the 23rd Annual Meeting of the International Society for Psychophysics, Tokyo, Japan, 20-23 October, 2007, Proceedings of Fechner Day vol. 23 (2007

Getting connected- at what cost? Some ethical issues on mobile HCI

The large scale deployment of mobile applications inevitably affects our daily lives and the whole culture. Not all of these effects are desirable. In a market economy, ethical issues are not the foremost drivers in the development of technology. In this paper, we ask whether the mobile human-computer interaction community could take an active role in discussing the issues which really matter in the development of technology for human beings, rather than concentrating on the fine tuning of emerging gadgets

Fluid technology design for development

Designing learning technologies for developmental contexts is a difficult problem. Based on an analysis of the development of the Zimbabwe Bush Pump, in this paper we apply the concept of ‘fluidity’ to technology design. The underlying principles are detailed and their relationship to issues in human computer interaction discussed
