integration of Applications into digital Television environment
2001Co-Authors: Chengyuan Peng, Pablo Cesar, Petri VuorimaaAbstract:The overall software system integration to run interactive services in set-top box is hard and essential since there is no ready system to ensure the cross-platform interoperability of the Applications. This paper presents a layered system integration model, which consists of interoperable Applications, Application Programming Interface (API), system software, and software and hardware resources. The digital Television Applications are classified into three categories according to the service architecture. All Applications are managed and controlled by an application manager, which plays a central role in the model. The set-top box hardware prototype used in the system is a single board computer. Linux with selected modules was chosen as the set-top box operating system. Kaffe Java virtual machine was ported to Linux platform to interpret Java bytecodes of Applications. A working prototype system is introduced in the paper. Finally, we give the system running results and further improvement.

user interface design principles for interactive Television Applications
International Journal of Human-computer Interaction, 2008Co-Authors: Konstantinos ChorianopoulosAbstract:Interactive Television (ITV) Applications gratify entertainment needs and leisure activities in a relaxed domestic context. Then, the mentality of efficiency and task completion implied by many user interface heuristics may not be suitable for design and expert evaluation of ITV. In line with the contemporary movement towards the design of the user experience of computing systems, a set of design principles for ITV Applications has been developed. Instead of information technology, the field of communication science was explored, which has accumulated an extensive theory of TV usage and viewer behavior. For the empirical validation, the principles were employed in the design of an interactive music TV application. The results suggest that a small set of generic principles could support the systematic design of ITV Applications and produce a design rationale that is traceable and comparable to alternative solutions, during the process of early product development. In addition, the principles could be refin...

Affective usability evaluation for an interactive music Television channel
Computers in Entertainment, 2004Co-Authors: Konstantinos Chorianopoulos, Diomidis SpinellisAbstract:Computer-mediated Television brings new requirements for user interface design and evaluation, since interactive Television Applications are deployed in a relaxed domestic setting and aim to gratify the need for entertainment. Digital video recorders, the generation of custom computer graphics on each digital set-top box, and the introduction of new advertising formats are important issues for research and practice. We explore the employment of an animated character and the dynamic insertion of advertising in the design of an intuitive user interface for interactive music-video Television. We found that the animated character and the skippable videoclip feature seamlessly enhanced consumer satisfaction, as shown by affective usability questionnaires.

HICSS - Needs and Gratifications for Interactive TV Applications: Implications for Designers
2003Co-Authors: J. Livaditi, K. Vassilopoulou, C. Lougos, Konstantinos ChorianopoulosAbstract:This paper uses the well-established uses and gratifications' theory in order to understand and categorize viewers' needs in the context of digital TV Applications. The results of this analysis unveil that such needs can either be ritualized or instrumental. Furthermore, the uses and gratifications theory was applied in order to formulate a questionnaire to which 68 current users of digital TV responded. The results of this empirical study reveal that Applications most suitable for the interactive Television environment should aim at the gratification of ritualizedneeds, such as entertainment and communication. Therefore, Applications that appeal to instrumental needs, such as information and transactions should be included as add-ons to entertainment and communication services. Finally, the implications of this analysis for the design of interactive Television Applications are exploited.

evaluating the usability of interactive digital Television Applications
International Conference on Information Technology: New Generations, 2013Co-Authors: Andrés Solano, Cristian Rusu, César A. Collazos, Luis MerchanAbstract:The evaluation of the usability of an interactive system is one of the most important steps in the user-centered design approach. Usability evaluation methods are quite diverse and many of them may be used to evaluate Interactive Digital Television (iTV) Applications. Questions arise when deciding which method and/or combination of methods give more (relevant) information. Three iTV Applications have been evaluated, applying several usability evaluation methods. Based on the effectiveness and efficiency of these methods, this paper proposes a methodology to evaluate the usability of iTV Applications.

Evaluating interactive digital Television Applications through usability heuristics
Ingeniare. Revista chilena de ingeniería, 2013Co-Authors: Andrés Solano, Cristian Rusu, César A. Collazos, Jose L. ArciniegasAbstract:La Television Digital Interactiva (TDi) es considerada como la convergencia de la Television y las tecnologias de la computacion. La evaluacion de usabilidad para aplicaciones basadas en tecnologias emergentes trae nuevos retos. La principal caracteristica de la TDi es que los usuarios pueden interactuar con las aplicaciones; de esta manera la usabilidad es el principal aspecto a considerar cuando se disenan aplicaciones de TDi. Las investigaciones actuales normalmente estan enfocadas sobre las aplicaciones de TDi desde un punto de vista tecnico, y no desde un enfoque centrado en el usuario. Hay una necesidad de nuevos metodos de evaluacion de usabilidad o, por lo menos, utilizar de nuevas formas los metodos de evaluacion existentes. Un conjunto de heuristicas de usabilidad especificas ha sido definido y validado, con el objetivo de ayudar en la evaluacion de usabilidad de aplicaciones de TDi. Tambien se ha propuesto una lista de verificacion para ser usada al momento de aplicar las heuristicas de usabilidad.

evaluating interactive digital Television Applications through usability heuristics evaluando aplicaciones de Television digital interactiva a traves de heuristicas de usabilidad
2013Co-Authors: Andrés Solano, Cristian Rusu, César A. Collazos, Jose ArciniegasAbstract:Interactive Digital Television (iDT) is considered as the convergence of Television and computer technologies. Usability evaluation for Applications based on emerging information technology brings new challenges. The main iDT feature is that the user may interact with the application; therefore usability should be a main concern when designing iDT Applications. Current research usually focuses on iDT Applications from a technical point of view, rather than a user–centered approach. There is a need for new usability evaluation methods or at least for the use of traditional evaluations in novel ways. A set of specific usability heuristics was defined and validated, in order to help the usability evaluations of iDT Applications. A usability checklist to be used when applying iDT heuristics is also proposed.

Methodological proposal to evaluate the usability of Interactive Digital Television Applications
2012 7th Colombian Computing Congress (CCC), 2012Co-Authors: Andrés Solano, Cristian Rusu, César A. Collazos, Jose L. ArciniegasAbstract:Usability is considered one of the basic attributes of any interactive system. It is a concept that includes a set of metrics and methods with the objective to obtain systems easy to use and easy to learn. The usability evaluation methods, that allow the measurement of the usability attributes, are diverse. Its realization depends of variables like costs, time availability, human resources, etc. A large number of usability evaluation methods can be used to evaluate Interactive Digital Television - iDT Applications, but the unknown is the level of information that gives each of them and/or combination with each other. This investigation is focused on the analysis of the usability evaluation methods in iDT Applications, providing a usability evaluation methodological proposal, in order to obtain the major amount of relevant information when evaluating this type of Applications.

A research on typing methods for interactive Digital Television Applications
IEEE Latin America Transactions, 2015Co-Authors: Aurora Barrero, David Melendi, Xabiel G. Pañeda, Roberto García, Laura Pozueco, Jose L. ArciniegasAbstract:It has been several years now since we started to experience a change in traditional Television services. Recently, the digitalization of these services has improved the usage of the available electromagnetic spectrum, increased the quality of the service and increased the number of channels. The next step in this evolution is the transformation of traditional Television into a fully interactive service. This change allows users to run Applications on the Television, similar to those of mobile phones or computers. Nevertheless, the main interaction device delivered with Televisions and set-top-boxes is still the traditional remote control. This device is suitable to perform certain actions such as move a pointer or select something, but it has not been designed to carry out more complex actions such as writing text. In this paper we present the main outcomes of a project aimed at researching typing methods for interactive digital Television services. During the project we have carried out several experiments with real users, who had to use different typing methods and devices that may be suitable for interactive digital Television Applications
