  This study builds on the innovation management and organizational knowledge networks to examine the user interactions in an intra‐organizational innovation platform of a Norwegian telecommunications operator, as well as the influence of user interactions on idea development. Although current studies mainly focus on user interactions and idea quality in innovation processes, little attention has been paid to the layered nature of user interactions that impact on idea development. Data from an intra‐organizational innovation platform, called Explorathon, was used in an exploratory study, with a mixed‐methods approach. For 10 days, 3200 employees posted 390 ideas, with 1435 comments. Results show that employees communicated through the innovation platform with 11 interaction types, eight contribution types and three collaboration types. The findings demonstrate that diverse platform interactions coexist and have a diverse impact on ideas. The authors suggest three types of contribution qualities—passive, efficient and balanced—that reflect the degree of meaningful interactions around an idea. The contribution qualities are only indicative of the content of interactions and they complement other evaluation metrics of the innovation platform. The findings also suggest that the user roles of idea contributors and platform moderators or facilitators are significant in maintaining interactions and weighted contributions over time. The study has implications both for research and practice.

  Design for motivation constitutes a design practice that focuses on the activation of human motives to perform an action. There is an increasing need to design motivational and engaging mechanisms for voluntary systems, such as innovation platforms, where user participation is a key target. When designing for motivation, a challenge of the early design phases is the selection of appropriate design tool and strategy. The current work presents a design tool, namely DEMO (DEsign for MOtivation), and evaluates its design process. The tool provides multidisciplinary teams with a user-centred, structured method to ideate and ultimately develop a consistent design plan to engage the users of innovation platforms. The evaluation study analysed the tool’s contribution to the design of motivational innovation platforms, utilising three data collection methods: a protocol analysis, interviews and questionnaires. The results discuss the experiences of 32 users with the development of motivation concepts, the group and the user activities, as well as their creativity aspects. Structured processes and the use of artefacts were found to be productive practices in the early design phases. The results also highlight the importance of multidisciplinary and user-centred teams that can enhance collaboration and communication during the design processes.

  This research presents a mobile augmented reality (MAR) travel guide, named CorfuAR, which supports personalized recommendations. We report the development process and devise a theoretical model that explores the adoption of MAR applications through their emotional impact. A field study on Corfu visitors (n=105) shows that the functional properties of CorfuAR evoke feelings of pleasure and arousal, which, in turn, influence the behavioral intention of using it. This is the first study that empirically validates the relation between functional system properties, user emotions, and adoption behavior. The paper discusses also the theoretical and managerial implications of our study.

  This paper describes the application of Latent Semantic Analysis to the term-document matrices that result from modeling an action game. Innovative solutions to address challenges like the definition of “words” and “documents” in the dynamic and complex domain of action games are proposed, and interesting, previously unknown semantic information is extracted.

  Similarity measurement between two musical pieces is a hard problem. Humans perceive such similarity by employing a large amount of contextually semantic information. Commonly used content-based methodologies rely on information that includes little or no semantic information, and thus are reaching a performance “upper bound”. Recent research pertaining to contextual information assigned as free-form text (tags) in social networking services has indicated tags to be highly effective in improving the accuracy of music similarity. In this paper, we perform a large scale (20k real music data) similarity measurement using mainstream content and context methodologies. In addition, we test the accuracy of the examined methodologies against not only objective metadata but real-life user listening data as well. Experimental results illustrate the conditionally substantial gains of the context-based methodologies and a not so close match these methods with the real user listening data similarity.

  This paper presents the results of an ongoing qualitative study with employees working with innovation in a Scandinavian company. Using Design Thinking as an approach, the paper analyses how different tools are used to initiate innovation processes. Issues like innovation drivers, team structure, creativity, information flow among teams, usefulness and challenges of using the methods and tools are discussed. The role of different design tools in innovation processes opens the discussion for possible future directions. The results suggest that many methods and tools could generate value in regards with the innovation processes, while there are many challenges that need to be considered. The findings could be beneficial primarily for companies that facilitate DT methods, designers, developers, managers and other involved members in innovation activities could gain insights on how to implement DT methods and tools.

  Player modeling is a crucial procedure for the user-oriented videogame design. For player modeling to be achieved, modeling domain knowledge is essential. Mastering the semantics of a domain is to learn the "language" of the domain. In the present study, two approaches to representing "words" are considered and analyzed comparatively. The first approach ("grid" representation) is based on the division of the game terrain as a grid, capturing in each cell the content-based information of the action game. The second approach ("holistic" representation) captures the contextual information in which the action takes place (life, score, shield, number of hit asteroids etc.). For the present comparative analysis, we use the action videogame SpaceDebris. We analyze the data using the classification algorithms J48, Naive Bayes, and SMO, as well as the K- means clustering and we compare the results in an attempt to identify the approach that represents the semantic space more reliably. The data acquired from the "grid" representation perform better, however the low value of the performance's difference does not allow us to come to rock solid conclusions.
