  • Tsekouras, George E.; Darzentas, Dimitrios; Drakoulaki, Ioanna; Niros, Antonios (2010) Fast Vector Quantizationpresented at and published in proceedings of IEEE World Congress on Computational Intelligence http://www.wcci2010.org

 

Abstract— In this paper we introduce a novel fuzzy vector quantization algorithm that tries to solve certain problems related to the implementation of fuzzy cluster analysis in vector quantization. The proposed method employs an objective function that combines the merits of fuzzy and crisp clustering in a uniform fashion. The algorithm’s structure encompasses two basic design strategies. The first one concerns the transition from fuzzy mode, where each training vector is assigned to more than one codewords, to crisp mode where each training vector is assigned to only one codeword. To accomplish this, we use analytical conditions that are extracted by the minimization of the aforementioned objective function. The second one is a specially designed pattern reduction module that helps to significantly reduce the computational cost. This module acts upon a training vector as soon as it is transferred in crisp mode. The resulting vector quantization scheme is fast and easy to implement. Finally, simulation experiments show that the method is efficient, while it appears to be insensitive with respect to the selection of its design parameters.

 

  • Wolfgang Hürst, Darzentas Dimitrios, (2012) Quantity versus Quality – The role of layout complexity in thumbnail based video retrieval interfaces.
    presented at and published in proceedings of ACM International Conference on Multimedia Retrieval, Hong Kong, 2012, http://www.icmr2012.org/

 

Abstract— In this paper we present our findings from an experiment designed to test the effectiveness of complex, thumbnail based layouts and the interaction methods required, in video retrieval scenarios for handheld devices such as smartphones. Our evaluation explores the relationship between the number of thumbnails (Quantity) visible on screen and their discernible detail (Quality) with regards to the related necessary amount of interaction. The results indicate that such layouts achieve a very high rate of accuracy and speed but that the nature of the interaction is of critical importance for the success of the system.

 

  • Darzentas et al, (2012), Mastering Technology for Greater Autonomy; Device Familiarisation for Older Users via Gamespresented at and published in proceedings 6th European Conference on Games Based Learning, Cork

 

Abstract— Technology is all around us, and many technologically enabled devices are not well used or understood. A case in point is that of kitchen appliances. The basic tool for familiarising oneself with these is via manuals, although in practice people also learn by watching others, by asking for advice from friends and relatives, and by trial and error. When people cannot learn in this way, the only resource is the (paper) manual, which is rarely motivating. Teaching and familiarisation techniques need a way to overcome this inadequacy and engage users’ attention, whatever their knowledge, background, or abilities. Ideally they should entice and motivate users to learn the paradigms and operating procedures of any device. This paper describes an attempt to introduce game design elements into the familiarisation process; as well as gamification layers; and for the manuals themselves follow the example of games, whose stand alone manuals have become “re-mediated” into in-game tutorials and instructions. Integrating the manual with the use of the device, which is technologically feasible, could offer a way to motivate users to become more proficient with domestic appliances. Simply put, using the device, and having fun doing so, rather than experiencing frustration and uncertainty, could aid in achieving the goal of understanding and using the device and its functionality more fully. The task of device familiarisation, although mundane, is not trivial. The importance of being autonomous in the home, that is, being able to prepare food and to carry out basic domestic chores, does not relate only to satisficing bodily needs, but to social functioning and self-esteem, and this is especially important for older people. Moreover, this approach could be generalised to other technological devices, beyond kitchen appliances. Designing the interaction experience to be attractive and engaging, by using game properties, could offer a new worthwhile approach to this problematic situation, and be of interest to the field of games based learning.

 

  • Wolfgang Hürst, and Dimitri Darzentas. HiStory: a hierarchical storyboard interface design for video browsing on mobile devices. presented at and published in proceedings of Mobile Ubiquitous Multimedia 2012, page 17. ACM, (2012)

 

Abstract— This paper presents an interactive thumbnail-based video browser for mobile devices such as smartphones featuring a touch screen. Developed as part of on-going research and supported by user studies, it introduces HiStory, a hierarchical storyboard design offering an interface metaphor that is familiar and intuitive yet supports fast and effective completion of Known-Item-Search tasks by rapidly providing an overview of a video’s content with varying degrees of granularity.

 

  • Darzentas et al., Motorway Jive: A game for investigating the implications of unimodal output in the design of immersive accessible experiences. presented at and published in proceedings of Interactive technology and Games 2013. Chosen for promotion to the Journal of Assistive Technology.

 

Abstract— Traditional game design relies heavily on both audio and visual output for interactivity and to support immersion, producing games that are to a greater or lesser extent inaccessible to users with sight or hearing impairments. In this paper we explore the implications of unimodal interactions on users’ experiences of games by developing a game which can be played purely with visual or audio output.  An immersion focused study is described in which we evaluated users’ experiences playing the game in all available modes: audio-only, visual-only and combined audio-visual. Our findings reveal that visual-only experiences are comparable to traditional multimodal interaction in terms of difficulty but struggle to create immersion, whereas audio only experiences are highly immersive, present a greater challenge and are generally preferred by users. This work suggests that there is potential to create immersive gaming experiences which are enjoyable for all and accessible to blind and partially sighted individuals.
