A Study of Interaction, Visual Canvas, and Immersion in AR Design: A DSR Approach

Augmented reality (AR) as an innovative technology has changed the way people use technology for interaction and communication. While researchers have studied the application of AR, research on AR as a communication medium remains scant. In this study, we investigate the effect of AR factors (namely, interaction, visual canvas/cues, and immersion) on AR-mediated communication. We apply design science research (DSR) guidelines to design, develop, and evaluate an AR artifact. We derive the design elements based on interactivity, media naturalness, and immersion theories and develop the AR artifact as a mobile app in an iterative manner. We evaluate the design product through the informed arguments and scenarios method, and the design process by assessing its conformance to DSR principles. We show that AR factors\u27 design elements—interaction (user controls, contextual tasks, and ergonomics), visual canvas/cues (realistic 3D models, visual and audio cues, and aesthetics), and immersion (diverse components)—play a critical role in AR-mediated communication. Furthermore, high-quality product visuals and interactive user controls give users a good AR experience. From a practice perspective, AR app designers may incorporate the design process we used in our study and generate AR experiences that fully exploit AR media’s communication affordance. We contribute to knowledge by using DSR guidelines for designing and developing AR as a communication medium

Icemaker^(TM): an excel-based environment for collaborative design

The creative process of team design can be rapid and powerful when focused, yet complex designs, such as spacecrafit, can slow and quench the essential elements of this process. Concurrent Engineering techniques partially address this problem, but a fuller realization of their benefits require an approach centering on the human aspects of teamwork. ICEMaker^(TM) is a Microsoft Excel® based software tool that facilitates closer-to-ideal collaboration within teams employing the new Integrated Concurrent Engineering (ICE) methodology. ICE is a generic approach that emphasizes focused collaborative design in a single-room context, and is now employed at several aerospace organizations to increase the productivity of design teams defining complex early development-phase products. By way of introduction, this paper describes the basic elements of ICE needed to understand ICEMaker and its application. We present the design approach, philosophy, and client-server architecture of the ICEMaker system, as well as a simplified user scenario. NASA's Jet Propulsion Laboratory (JPL) has recently adopted ICEMaker for its primary early-phase space mission and system advanced project design team, Team-X. We describe Team-X's experience with ICEMaker and report on the lessons learned, and qualitative product improvements, resulting from JPL's implementation of ICEMaker

EU Lentes da Experiência: ferramenta para avaliação e análise da Experiência do Usuário

The growing discussion of the User Experience resulting from the human-object interaction as a market differential brings to light the need to integrate the User Experience into the design practice of Design. Therefore, it is necessary to use appropriate tools and methodologies to consider the User Experience throughout the Design process. This article aims to present the EU Lenses of Experience and its application in a real case. The tool aims to consider the elements that make up the user experience when evaluating products, services, and digital interfaces and helps the designer in generating experience design guidelines. As a result, we obtained the presentation and application of a versatile tool for different types of projects, covering three major domains: physical product, service, and digital interface. The EU is an instrument to be integrated into the design practice of Design and is formed by three components: the Experience Reference Blocks, the Experience Mapping Canvas, and the Experience Aspects Lens.A crescente discussão da Experiência do Usuário resultante da interação homem-objeto como diferencial de mercado traz à tona a necessidade da integração da Experiência do Usuário à prática projetual de Design. Por isso, se faz necessário o uso de ferramentas e metodologias adequadas para a consideração da Experiência do Usuário ao longo do processo de Design. Este artigo tem como objetivo apresentar a EU Lentes da Experiência e sua aplicação em um caso real. A ferramenta visa considerar os elementos que compõem a experiência do usuário na avaliação de produtos, serviços e interfaces digitais e auxilia o projetista na geração de diretrizes de projeto da experiência. Como resultado, obteve-se a apresentação e aplicação de uma ferramenta versátil quanto a diferentes tipos de projeto, contemplando três grandes domínios: produto físico, serviço e interface digital. A EU é um instrumento a ser integrado na prática projetual de Design e é formada por três componentes: os Blocos de Referência da Experiência, o Canvas de Mapeamento da Experiência e as Lentes dos Aspectos da Experiência

Emotion-centred design : a human factors approach in affective web design : a thesis for fulfilment of a Master of Philosophy degree, College of Design, Fine Arts and Music

This thesis hypothesised that a major factor in the failure of many e-Commerce ventures was the lack of emotion imparted into the design, with trust barriers still being to the fore, and a lack of affective human factors like fun, pleasure and joy in the user experience. The human brain often acts emotionally before rationally and this affects initial reactions to experiences and the propensity to purchase online. A key to understanding human-computer communication is that form should follow emotion (as well as function). A wide range of design concepts and theories are analysed for linkages to human emotion due to the exploratory nature of this thesis. Aspects of New Media design such as video, sound, images, colour and virtual reality are covered along with previous research into affective human factors; transferability of emotional elements from other products; and the importance of trust and prevention of negative emotions. Case examples are provided throughout via screenshots and commentary, including a special section on the way that the Nike site has met many emotional design criteria. Research into the opinions of designers and users is undertaken via questionnaires to verify literary findings and measure views on emotional appeal within Websites. It was found that there are misunderstandings of human-computer communication - with designers not meeting user expectations in some areas, even though many designers agree that emotional design is important. In particular, there needs to be a better understanding of how to integrate fun, social contact, colour, trust and sound into designs. Emotion is core to human function, and evolution has seen the emotional parts of the brain grow long before rational areas arose. Given the importance of emotion it is only natural that an emphasis should be placed on it in design philosophies. Whilst some designers are realising the importance of this in consumer products this concept needs to be further emphasised in the world of e-Commerce. Designers surveyed in this thesis were nearly all following a form follows function or a subjective/intuitive design philosophy. However, it was found that there was a good level of support (70%) for emotional design. A gap was established from this fact because only 45% believe they are currently using a high level of emotional design in practice. Chi-square tests showed that there were a number of significant relationships between the level of education and other questionnaire variables such as the importance of colour and recontextualising from car and game design. Establishing trust helps to overcome the core human emotion of fear. Branding, seals of approval and high quality navigation are amongst the elements that can assist in bridging human-computer distrust. Predispositions and previous experiences can also affect initial trust values. Questionnaire results found that designers still believe that lack of trust is a major psychological barrier to purchasing online. Major trust dimensions from previous empirical research were all deemed important. It was also found that users and designers rated trust near the top of emotional themes to concentrate on in Web design. Negative emotions (anger and frustration) can also arise if the design is not inherently usable. Usability was the top-rating design theme amongst designers. There has to be a good balance between the rational and emotional sides. Further negative emotions can be evoked if the site is slow or if there are delays. Speed of loading was amongst the top emotional design elements for both users and designers. It is a difficult line for designers to tread - on one hand using speed to prevent negative emotions, but on the other hand balancing the need for other design elements that generate positive emotions through fun and pleasure characteristics (that might slow things down). Designers involved in this study were very much in agreement with the importance of choosing colours to match the emotions they wanted to evoke in visitors (based on understandings of colour-emotion stereotypes and 'temperatures'). Colour can achieve harmonious interactions or cause rejection by the human brain depending on its application. The survey of users revealed that almost half of the respondents counted colour in their top 5 emotional themes, whereas designers did not think, it was as important as other emotive dimensions. Different cultures may respond differently to metaphorical images, colours, and dimensions such as power-distance and masculinity. Nearly all designers believed that empathising with target users (a part of emotional intelligence) was very important, as was involving users in the design process (usercentred design). Only 50% of users felt that designers were respecting their demographies and culture, so there is still a large number of people who feel they could be more satisfied in this sense. It is proposed that more user testing be carried out in conjunction with frameworks that rate cultural dimensions based on target audiences. The use of video and streaming media was portrayed to be a proposition requiring careful consideration and application by previous non-empirical references. Streaming video can connect with people on an emotional level, bringing in a degree of surprise and variation, and fully highlight the appealing characteristics of the product(s) trying to be sold online. Other New Media technologies such as virtual reality (VR) and 3D have been around for quite awhile (in computer games and scientific applications) but are yet to achieve widespread usage in Website e-Commerce. Some literature is against the use of VR and 3D on the Web but several companies have been receiving accolades in this area because of the ability to bridge an emotional gap between brands and consumers. Questionnaire results showed that most design respondents did not think streaming media, 3D and VR were important in order to gain emotional connections. However, higher bandwidth speeds that will facilitate more use of streaming media and 3D are deemed favourable by designers in terms of increasing emotional appeal. The need for social contact, familiarity and recognition of expressions and gestures led to the proposition of using virtual shop assistants and agents. Contact in the form of live text chat can also fulfil some social needs and plays a big part in portraying trustworthiness since a real person is being interacted with. Designers surveyed in this study were reasonably evenly distributed amongst those in favour, unsure and in disagreement with the use of agents. Surprisingly, given that users would not have had much exposure to virtual agents and characters online, they actually deemed them amongst the highest rating emotional design elements - creating a gap between user expectations and designer actions. Resources revealed that sound can account for a large part of an overall experience. Sound creates mood and atmosphere, and is present in the physical retail environment. Although literature stresses the importance of sound to Web design, designers in this study were of quite the opposite view. Sound was not deemed to be an important experience (near the bottom of ranked emotional dimensions). Users, however, rated sound amongst the middle group of emotional elements. More use of sound is an opportunity for the future. Two broad product ranges - automobiles and computer games - were investigated to see what made them such emotion-centred items. Cars and games evoke feelings of pleasure, fun, flow and fantasy because of their design. Designers favoured interactivity, colour use and fun as gaming elements best applied to Web design. More than half of designer respondents believed that the design of cars and games can be recontextualised into Web design, and most users were definitely in favour of seeing emotional elements they like about cars and games placed into Websites. Dimensions and potential mechanisms for measuring or assessing the emotional intelligence of Websites are proposed, and these include the use of semantic maps to position and compare Websites based on their performance against dimensions such as fun, warmth, trustworthiness, use of colour and the ability to engage users on a social level. The capability of building emotion into a Website is then balanced with the need for high-quality navigation, functionality and usability - as poor efforts in these 'rational' areas can lead to negative emotions and distrust. The design also has to keep in line with the demands of the company wanting the Website built. This study was exploratory - with the aim of bringing out into the open some aspects of New Media e-Commerce design that could he better utilised in order to match the emotions and feelings of customers - potentially leading to higher degrees of sales success. This thesis is therefore hoped to be a catalyst for further study in this area.<

"Paper in Screen" Prototyping a Rapid Technique to Anticipate the Mobile User Experience

Prototyping is generally acknowledged as an effective method for generating cost-effective, preliminary designs of various products including web and mobile user interfaces. Out of the existing types of prototyping, paper prototyping is known for being the most cost-effective of them all, as well as the most constrained for the realistic user experience elements it can render. High-Fidelity prototypes on the other hand offer a richer experience to the user, at the high cost of developing sophisticated software/hardware-based demonstrations. Although both of these types of prototypes continue to be widely and successfully used in product and interface design, there is no evidence of a cost-effective technique that would elicit user’s feedback which as rich as high-fidelity prototypes but without implementation effort. This study proposes an innovative prototyping technique called “Paper in Screen” (Bolchini, Pulido, Faiola, 2009) which enables designers to cheaply and rapidly prototype a mobile application in its key components (interface design and mobile device integration) without the need for implementing a high-fidelity prototype. A study was performed with 10 user experience professionals to evaluate their perception of the technique’s effectiveness, from which a number of benefits and drawbacks of the “Paper in Screen” were learned. The obtained results point to areas of future research in mobile prototyping

Designing and evaluating mobile multimedia user experiences in public urban places: Making sense of the field

The majority of the world’s population now lives in cities (United Nations, 2008) resulting in an urban densification requiring people to live in closer proximity and share urban infrastructure such as streets, public transport, and parks within cities. However, “physical closeness does not mean social closeness” (Wellman, 2001, p. 234). Whereas it is a common practice to greet and chat with people you cross paths with in smaller villages, urban life is mainly anonymous and does not automatically come with a sense of community per se. Wellman (2001, p. 228) defines community “as networks of interpersonal ties that provide sociability, support, information, a sense of belonging and social identity.” While on the move or during leisure time, urban dwellers use their interactive information communication technology (ICT) devices to connect to their spatially distributed community while in an anonymous space. Putnam (1995) argues that available technology privatises and individualises the leisure time of urban dwellers. Furthermore, ICT is sometimes used to build a “cocoon” while in public to avoid direct contact with collocated people (Mainwaring et al., 2005; Bassoli et al., 2007; Crawford, 2008). Instead of using ICT devices to seclude oneself from the surrounding urban environment and the collocated people within, such devices could also be utilised to engage urban dwellers more with the urban environment and the urban dwellers within. Urban sociologists found that “what attracts people most, it would appear, is other people” (Whyte, 1980, p. 19) and “people and human activity are the greatest object of attention and interest” (Gehl, 1987, p. 31). On the other hand, sociologist Erving Goffman describes the concept of civil inattention, acknowledging strangers’ presence while in public but not interacting with them (Goffman, 1966). With this in mind, it appears that there is a contradiction between how people are using ICT in urban public places and for what reasons and how people use public urban places and how they behave and react to other collocated people. On the other hand there is an opportunity to employ ICT to create and influence experiences of people collocated in public urban places. The widespread use of location aware mobile devices equipped with Internet access is creating networked localities, a digital layer of geo-coded information on top of the physical world (Gordon & de Souza e Silva, 2011). Foursquare.com is an example of a location based 118 Mobile Multimedia – User and Technology Perspectives social network (LBSN) that enables urban dwellers to virtually check-in into places at which they are physically present in an urban space. Users compete over ‘mayorships’ of places with Foursquare friends as well as strangers and can share recommendations about the space. The research field of Urban Informatics is interested in these kinds of digital urban multimedia augmentations and how such augmentations, mediated through technology, can create or influence the UX of public urban places. “Urban informatics is the study, design, and practice of urban experiences across different urban contexts that are created by new opportunities of real-time, ubiquitous technology and the augmentation that mediates the physical and digital layers of people networks and urban infrastructures” (Foth et al., 2011, p. 4). One possibility to augment the urban space is to enable citizens to digitally interact with spaces and urban dwellers collocated in the past, present, and future. “Adding digital layer to the existing physical and social layers could facilitate new forms of interaction that reshape urban life” (Kjeldskov & Paay, 2006, p. 60). This methodological chapter investigates how the design of UX through such digital placebased mobile multimedia augmentations can be guided and evaluated. First, we describe three different applications that aim to create and influence the urban UX through mobile mediated interactions. Based on a review of literature, we describe how our integrated framework for designing and evaluating urban informatics experiences has been constructed. We conclude the chapter with a reflective discussion on the proposed framework

Towards a kansei-based user modeling methodology for eco-design

We propose here to highlight the benefits of building a framework linking Kansei Design (KD), User Centered Design (UCD) and Eco-design, as the correlation between these fields is barely explored in research at the current time. Therefore, we believe Kansei Design could serve the goal of achieving more sustainable products by setting up an accurate understanding of the user in terms of ecological awareness, and consequently enhancing performance in the Eco-design process. In the same way, we will consider the means-end chain approach inspired from marketing research, as it is useful for identifying ecological values, mapping associated functions and defining suitable design solutions. Information gathered will serve as entry data for conducting scenario-based design, and supporting the development of an Eco-friendly User Centered Design methodology (EcoUCD).ANR-ECOUS

The Contemporary Understanding of User Experience in Practice

User Experience (UX) has been a buzzword in agile literature in recent years. However, often UX remains as a vague concept and it may be hard to understand the very nature of it in the context of agile software development. This paper explores the multifaceted UX literature, emphasizes the multi-dimensional nature of the concept and organizes the current state-of-the-art knowledge. As a starting point to better understand the contemporary meaning of UX assigned by practitioners, we selected four UX blogs and performed an analysis using a framework derived from the literature review. The preliminary results show that the practitioners more often focus on interaction between product and user and view UX from design perspective predominantly. While the economical perspective receives little attention in literature, it is evident in practitioners writings. Our study opens up a promising line of request of the contemporary meaning of UX in practice.Comment: 8 pages, 1 figure, 3 table
