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)

Interaction design for dyslexic children reading application: A guideline

This paper outlines and explains the guideline needed to design an effective interaction design (IxD) for dyslexic children’s reading application.The guideline is developed based on theories that underly dyslexia and its effects towards reading, with emphasis given to the visual related theories and phonological deficit theory and core-affect theory.The needs of a dyslexic child to read properly and correctly with understanding of the related theories inspires the development of this guideline as it is aimed to aid the process of learning to read by facilitating them with useful design.Tested on a number of dyslexic children, the design seems to reduce their memory load for this particular task and thus reduce their difficulties in reading.Hence the role of an interaction designer is needed to answer the whats and hows and to design an interactive product (in this case–reading applications) to help dyslexic children to read

A Research Agenda toward Assessing Perceived Affective Quality of IT

Most IT evaluation and usage studies emphasize cognition or high-order affective reactions that come from more deliberate cognitive processing. A primitive concept, perceived affective quality (PAQ) of IT, has not yet attracted much attention. PAQ refers to an individual’s perception of IT’s ability to change his/her affective state. IS and psychology literature shows that PAQ has significant impacts on higher-order affect, cognition, and behaviors. Thus understanding the nature and measurement of PAQ is of great importance. However, there is no PAQ instrument specifically designed for IT. This study intends to develop and validate such an instrument based on literature review and surveys. This scale will provide researchers with a useful tool to identify favorable affective quality of IT. It will also help IT managers and designers to provide better products and enhance profits

Visual aesthetics and the user experience

User experience is conceptualized as a phenomenon consisting of instrumental and non-instrumental quality perceptions as well as emotional user reactions. Visual aesthetics is defined as one non-instrumental quality and available methods are applied to measure the perception of visual aesthetics of interactive systems. Selected results of two studies are reported that addressed the influence of perceived usability and visual aesthetics on emotional user reactions and consequences of user experience and studied the effect of user characteristics and contextual parameters on these relations. The results show that usability and visual aesthetics can be perceived independently. Furthermore, the relevance of perceived visual aesthetics for emotional user reactions and consequences of user experience is demonstrated. However, the results reveal that the importance depends on user characteristics, e.g. the centrality of visual product aesthetics, and context parameters, e.g. the goaldirectedness of the interaction

Perceived Affective Qualities in Flight Deck Design

Conference Proceedings final program is available at: https://ahfe.org/files/AHFE2023_FinalProgram.pdf .Abstract: Human Factors/Ergonomics (HF/E) practices in aviation generally focus on the system’s functional features like human performance, human error, workload, and situation awareness, without considering the emotional aspects of the interaction. However, there is a shift from a cognitive perspective to an affective one, which concerns promoting pleasure instead of just preventing design deficiencies. While traditional human factors have focused on efficiency, usability, and safety, emerging approaches have also focused on product experience. There has been a growing interest in affect and pleasure in such areas as engineering design, psychology, neuroscience, human factors, and industrial design. This study aims to transfer these emerging approaches into aviation by determining the perceived affective qualities in a flight deck design. For this purpose, interviews were conducted with pilots by using the Repertory Grid Technique with Laddering Technique to elucidate how pilots experience a flight deck design. According to the results, 33 constructs were determined which show the qualities of attributes produced by flight deck and the affective states of pilots when these qualities are provided

Using Ratings and Response Latencies to Evaluate the Consistency of Immediate Aesthetic Perceptions of Web Pages

Using explicit (subjective evaluations) and implicit (response latency) measures, this study replicated and extended the findings by Fernandes et al (2003), who found that immediate aesthetic impressions of web pages are remarkably consistent. Forty participants evaluated 50 web pages in two phases. The degree to which web pages were regarded, on average, as attractive after a very short exposure of 0.5 sec. was highly correlated with attractiveness ratings after an exposure of 10 seconds. Extreme attractiveness evaluations (both positive and negative) were faster than moderate evaluations, providing convergent evidence to the hypothesis of immediate impression. Overall, the results provide direct evidence in support of the premise that aesthetic impression of the IT artifacts are formed quickly. Indirectly, the results suggest that visual aesthetics can play an important role in users\u27 evaluations of the IT artifact

Positive and Negative Affect in IT Evaluation: A Longitudinal Study

This study investigates the impacts of affective evaluations of IT on IT use decisions. We propose two object-based affective evaluation constructs: perception of an IT’s capability to induce positive affect (PC-PA) and perception of the IT’s capability to induce negative affect (PC-NA). A longitudinal study shows that PC-PA and PC-NA are distinct concepts that have different effects on commonly studied IT adoption factors, perceived usefulness (PU), perceived ease of use (PEOU), and attitude toward using the IT (ATB). These effects hold true during both initial use and continued use. PC-PA influences PU, PEOU and ATB but becomes less important to PU over time, and PC-NA only influences PEOU but becomes more important to PEOU over time. The study also offers a specific instrument on measuring affective evaluations of IT and points out future research directions

Theorizing the Relationship between Affect and Aesthetics in the ICT Design and Use Context

With an increasing interest in both affect and aesthetics in the context of information and communication technology (ICT) design and use, there is a timely need to provide a theory based understanding of these concepts and their relationships. In this paper, we point out some confusion as shown in the literature and provide a theory based understanding of the concepts and their relationships. Such an understanding can eventually provide practical suggestions on researching affect and aesthetics in the ICT context and suggest researchers to expand the coverage of aesthetics concept from focusing primarily on pleasantness or positivity to a broader coverage indicated by affect’s structure
