The curious case of the refrigerator-TV: similarity and hybridization

This paper examines the role of similarity in the hybridization of concepts, focusing on hybrid products as an applied test case. Hybrid concepts found in natural language, such as singer songwriter, typically combine similar concepts, whereas dissimilar concepts rarely form hybrids. The hybridization of dissimilar concepts in products such as jogging shoe mp3 player, and refrigerator TV thus poses a challenge for understanding the process of conceptual combination. It is proposed that models of conceptual combination can throw light on the judged future success and desirability of hybrid products in general. The composite prototype model proposes two stages of conceptual combination. In the first stage, the concepts are aggregated into an additive hybrid, simply by forming the union of the two sets of attributes. In the second stage, any conflicting attributes are identified and resolved, often with the introduction of emergent attributes, resulting in an integrative hybrid. Across four studies that varied the similarity and type of hybrid products, similar and integrative hybrids were valued more than dissimilar and additive hybrids. Critically, though, dissimilar hybrids were also highly valued if they were integrative. Results supported the two stages proposed by the composite prototype model, and implications for other models of hybrid formation are discussed

The Design of Information Technology as Design of the Information Society

The design of technical product is often focused in the development of that particular artefact. However, when we introduce new technology we don’t simply replace old technology with new, but change many things in the whole context of use. With the help of familiar examples from our everyday life we illustrate how far-reaching tiny-looking technological changes may be. Finally, we propose a design model which combines the traditional user-centred design cycle with broader view. The premise of the proposed model is that when designing information technology we fundamentally design information society

A Universalist strategy for the design of Assistive Technology

Assistive Technologies are specialized products aiming to partly compensate for the loss of autonomy experienced by disabled people. Because they address special needs in a highly-segmented market, they are often considered as niche products. To improve their design and make them tend to Universality, we propose the EMFASIS framework (Extended Modularity, Functional Accessibility, and Social Integration Strategy). We first elaborate on how this strategy conciliates niche and Universalist views, which may appear conflicting at first sight. We then present three examples illustrating its application for designing Assistive Technologies: the design of an overbed table, an upper-limb powered orthose and a powered wheelchair. We conclude on the expected outcomes of our strategy for the social integration and participation of disabled people

The impact of using location-based services with a behaviour-disordered child

In this paper we explore technologies that help parents locate their children. Parents regularly use mobile phones to stay in touch with their children, but recent developments in location-based tracking allow parents to assess the location of their child directly. Such location-based services offer new assurances, but also bring new privacy challenges. In order to explore these, we conducted a case study focussing on the way in which a family has used location-based technologies to keep track of a child with Aspergers Syndrome and Attention Deficit Hyperactivity Disorder. This novel research shows that Location-Based Services, although usually applied to lone-worker situations, can be effectively applied to other user groups. The parents of the child were interviewed at length, and the interview was analysed using qualitative methods. The findings are discussed and considered against a current predictive model of LBS use

Consumer-based Application Customization for Mobile Phones

There is an interest among users for customization of mobile phones, as is indicated by several companies and websites which offer themes, ringtones, backgrounds and games. However, unless the users possess programming experience, this customization rarely goes beyond simple look-and-feel and into the actual functionality. In the other end of this spectrum, lies End User Development (EUD), where end users with programming expertise make modifications to programs themselves. In their work of designing a system for Sony Ericsson – meant to enable end users without programming knowledge to customize applications and functionality for mobile phones – the authors identified this gap between users and developers – the EUD gap. The authors believed this was the cause of frustration among some users, who perhaps did not have the motivation to learn how to program, but nonetheless wished for more control of applications and functionality in their cell phones. With the main purpose of designing a system meant to support users in such a task, this thesis has also looked at how such a solution could function in a larger, EUD-related perspective. Apart from presenting a final design proposition, the authors find indications for that there is, indeed, an interest among users to customize the functionality of mobile phones. Findings, possible implications, and recommendations based on the authors' own experience of developing the system, are finally presented, both out of an academic and a commercial perspective

Usability Enhancement of SMS Interface for Illiterate Users

This article analyzes several User Interface (UI) designs and puts forward some more general design principles for interfaces designed for low-literate users. The results of this study highlight the importance of text-free interfaces compared to text-based interfaces for the illiterate and low-literate population. The study developed a Short Message Service (SMS) interface consisting of many design elements, including graphical icons, voice, and text reduction. The participants were more satisfied with the designed SMS interface as compared to the traditional text-based interface of SMS. We believe that if the user interface is appropriately designed, users will not need formal literacy, computer skills, or any external help to operate the application. It has been shown that an interface with minimal or no text but one or more graphics, audio, and digital components is helpful for users with low literacy rates

The influence of national culture on the attitude towards mobile recommender systems

Copyright @ 2013 Elsevier B.V.This study aimed to identify factors that influence user attitudes towards mobile recommender systems and to examine how these factors interact with cultural values to affect attitudes towards this technology. Based on the theory of reasoned action, belief factors for mobile recommender systems are identified in three dimensions: functional, contextual, and social. Hypotheses explaining different impacts of cultural values on the factors affecting attitudes were also proposed. The research model was tested based on data collected in China, South Korea, and the United Kingdom. Findings indicate that functional and social factors have significant impacts on user attitudes towards mobile recommender systems. The relationships between belief factors and attitudes are moderated by two cultural values: collectivism and uncertainty avoidance. The theoretical and practical implications of applying theory of reasoned action and innovation diffusion theory to explain the adoption of new technologies in societies with different cultures are also discussed.National Research Foundation of Korea Grant funded by the Korean governmen

Lead Markets: Drivers of the Global Diffusion of Innovations

Multinational corporations are often faced with regionally varying market conditions, local environments and demand preferences. This paper presents the lead markets concept of developing global innovation that takes advantage of the lead market phenomenon. A lead market is a regional market that is first to adopt global innovation designs. A system of five lead factors explains the lead role of a market: a demand advantage, a price advantage, an export advantage, a transfer advantage and a market structure advantage. The system of lead market factors is then evaluated in a detailed case study of the cellular mobile telephone industry. It is suggested that companies can harness lead markets for the development of global innovations. By developing and refining innovations in close interaction with the local environment of a lead market, a company can focus on a narrow range of preferences and feedback, lowering the risk of being locked into idiosyncratic environments, and generate true global innovations.International diffusion of innovation, R&D internationalisation, Market entry strategy

A Framework for Measuring the Usability Issues and Criteria of Mobile Learning Applications

With the continuing growth of mobile devices outpacing that of desktops and laptops, mobile devices have become the new personal computer. These devices have become increasingly sophisticated and extremely powerful in the last few years. Substantial work has been done to measure mobile applications’ level of quality; many researchers have attempted to figure out why certain applications fail and others succeed. In this thesis, a conceptual framework for measuring the quality aspects and criteria of m-learning is produced. Furthermore, a software prototype application for smartphones to assess usability issues of m-learning applications has been designed and implemented. This prototype application is developed using Java language and the Android Software development Kit, such that the recommended guidelines of the proposed framework are maintained. A questionnaire survey was conducted at Western University with approximately 96 undergraduate software engineering students. Five identical smartphones are used to evaluate the developed prototype in terms of ease of use, user satisfaction, attractiveness and learnability
