Online Communities: Approaches, Principles, Dilemmas

Online Communities: Approaches, Principles, Dilemmas

Authors: Irina Cristescu
( 10 downloads)
Abstract

Online communities mediated by computer facilitate the gathering and the group interaction throughout social support, information and the feeling of belonging. The social interaction areas created by technologies that allow users to interact with other groups assure the consolidation of social networks. The design and the development of interactive systems should be concerned with two important aspects: usability and sociability. When the group interest is in contradiction with the personal interest a new tension is created, a tension whose negative effects can not be neglected due to their implications on the group level. In the present article we analyze the design principles of online communities on grounds concerning the usability and sociability requests.

Abstract

In our paper we depict two modes of accessing Web services from mobile devices. These modalities correspond to different types of mobile devices, and, as a consequence, we use adapted client modules for each type. The software application depicted in our paper represents an easy way for informing of the members of an academic environment. It offers the possibility of an easy adaptation of user interface, so as to access the information faster, in concordance with user profile and his context. The architecture of this information system includes a common support at data level and at application level, on the server, but, at the client level, we developed distinct software components: for PocketPC mobile devices, which use Microsoft .NET Compact Edition, and, on the other part, for mobile phones incorporating Java 2 Platform Micro Edition.

Approaches on the Quality Evaluation of the On-line Public Services (e-ServEval)

Approaches on the Quality Evaluation of the On-line Public Services (e-ServEval)

Authors: Alexandru Balog
( 10 downloads)
Abstract

This paper describes two categories of approach (general and specific) regarding the quality evaluation of the on-line public services. The specific approach presents the e-ServEval model, designed and experimented in a national research project. The model takes into consideration characteristics regarding the quality of the interface, the quality of the interaction and of the result (outcome). The model is validated in relation to external factors (the user’s satisfaction and the intention of using the service).

Hedonic and pragmatic attributes in determining the mobile phone user experience

Hedonic and pragmatic attributes in determining the mobile phone user experience

Abstract

The present research represents an integrative approach of the user experience notion having the Hassenzahl model (2003) as a starting point. The integrative dimensions of our model are represented by: product characteristics, pragmatic attributes (ease of use, usability), hedonic attributes (stimulation, identification, evocation), consequences (satisfaction, pleasure and visual attraction) and the context of use (action vs. goal mode). This model is empirically tested in the field of mobile technology, more specifically in the field of mobile phone use. Our results indicate that all the aspects of the experience contribute significantly to the overall satisfaction of the mobile phone user, the pragmatic and hedonic attributes not being perceived as two different elements. Perceived user satisfaction is seen as a mediator between usability and visual attraction. Both pragmatic and hedonic attributes influences significantly satisfaction and visual attraction and the differences regarding the user experience are significantly influenced by context.

Abstract

The author prove that the advantages of computer games are increased if they are part of didactic system based on processing information at action, iconic and verbal level. Didactic game could reproduce trustily the reality elements at which students do not have direct access, but also an inherent directed activity, loved by those, with small steps and many feedbacks; could become complementary to all three plans, gives an action model for discover complex relationships from nature; starts cognition activity and mental image creation which extends outside activity. The most important arguments are given by research made in primary school (pupils 7-11 years old with mental impairment) which proved that, training the same thinking micro operations, at direct action level in nature, with things and creatures, than through images (which permit to detach stabile patterns for selective reflection of essential) and then at verbal level, contributes to increase formative efficiency of the teaching-learning process.

Language Resources for a Question-Answering System for Romanian

Language Resources for a Question-Answering System for Romanian

Authors: Verginica Barbu Mititelu, Alexandru Ceauşu, Radu Ion, Elena Irimia, Dan Ştefănescu, Dan Tufiş
( 10 downloads)
Abstract

We describe here several language resources (a lexicon, a paradigmatic morphology, two linguistic thesauri – the Romanian wordnet and Eurovoc – and a parallel multilingual corpus) from the perspective of their utility especially in question-answering tasks. We present the stages of the automatic finding of an answer to a question written by a user in a natural language. Wherever necessary, we show the way in which the linguistic resources contribute to various problems solving. The lexicon is a sort of spellchecker for the user’s question. The paradigmatic morphology is used for lemmatizing the question and the corpus. The Romanian wordnet is useful for query expansion, for identifying the lexical chains between words senses and for answers retrieval in a mono- and a multilingual system. The Eurovoc thesaurus is used for segmentation and lemmatization of the user’s question and of the parallel multilingual corpus from which the answer is retrieved. The architecture of the question-answering system described here is language independent; the language resources, however, are, inherently, language dependent (e.g. the lexicon, the paradigmatic morphology); exceptions make those whose organization or structure allows for a multilingual perspective (e.g. the thesauri and the corpus); in our case, they are aligned.

Abstract

This paper presents the WebVOX system, for Web page accessibility improvement for persons with reading deficiency. The presented solution addresses peoples with dyslexia, low literacy and reading skills, learning difficulties, visual impaired and color-blind persons and blind persons. Different reading deficiencies were analyzed, concluding the fact that reading problems go beyond anatomic eye functionality. In the context of described solution, different software assistive technologies were presented, both for blind and visual impaired peoples. Were described the functionalities of screen readers, speech synthesis and screen magnifiers; much of these functionalities are implemented in WebVOX. Should be emphasized the fact that proposed solution can improve the Webpage accessibility, but the way these pages are designed and realized should obey the W3C recommendations in order to obtain the full accessibility. At the end several existing solution were presented, both with their advantage and disadvantages.

A task-based design approach to the design of a software assistent for usability evaluation

A task-based design approach to the design of a software assistent for usability evaluation

Abstract

The quality of interactive systems is an important concern that brings in front the ergonomic quality of the user interface. Formative usability evaluation aims at identification and analysis of usability problems as early in the develompment process. For this purpose, a detailed description is needed as well as a classification according to different criteria: impact, context, explanation and suggestion for improvement. An acurate description which is agreed by the evaluation team and communicated to designers improves the product quality and motivates the process of fixing usability problems. In this paper we present a task-based approach to the design of a software tool to assist evaluators during the tasks of collecting, organization and retrieval of usability problems. In the case of heuristic evaluation and / or guidelines-based evaluation the software tools should satisfy two kinds of requirements: providing with appropriate heuristics / guidelines and recording of usability problems. These requirements are resulting from a task analysis and lead to develop a flexible software tool that could be used either as a stand-alone tool or integrated with an existing tool for working with guidelines.

An Ontology-centered Approach for Designing an Interactive Competence Management System for IT Companies

An Ontology-centered Approach for Designing an Interactive Competence Management System for IT Companies

Abstract

The paper presents an ontology-centered approach for designing an interactive competence management system for IT companies. This type of approach helps to shift the focus from a function-oriented, tool-centric view, towards a semantic-oriented view. In the paper are covered subjects as: ontologies definitions, generic architecture of the competence management system (CMS), structure of CMS ontology, building and working the ontology (integrity and inference of the ontology, knowledge acquisition, conceptualization phase, querying types of concepts). The advantage of using an ontology-based system is the possibility of the identification of new relations among concepts based on inferences starting from the existing knowledge. The user can choose to query instances of one type of concept, based on the relations that are displayed for him/her in a dropping menu. In addition to choosing relations modeled in the ontology, the user may also query inferred relations that are not explicitly stored in the knowledge base. Other search type is browsing the ontology. The skeleton of the ontology is seen as a tree with nodes and hyperlinks that point to other concepts or instances. Starting from base-concepts, the user can get specific information about any instance or concept. The paper also presents some use-cases, conclusions and further developments.

Cognitive task analysis: theoretical and methodological aspects

Cognitive task analysis: theoretical and methodological aspects

Authors: Ana Maria Marhan
( 10 downloads)
Abstract

This paper discusses some of the theoretical and methodological challenges faced by nowadays users of cognitive tasks analysis (CTA) techniques. Despite the fact that CTA is recognised as an important prerequisite for the HCI design process, offering important benefits for quality of a final product, more than often the designers will rather ignore the presentations of CTA techniques provided by sophisticated research reports and papers. A communication effort would be therefore necessary in order to identify and present relevant information for practical applications in a more user-friendly manner, easier to be comprehended, and transferred into practice, with clearer usability bench-marks and more precise directions regarding its integration in subsequent designing stages. It is suggested that a further challenge would be to test various CTA techniques in real design contexts, and asses their effectiveness and efficiency against specific tasks and situations, special design problems and particular organizational structures.

Practical Approaches for Interdisciplinary Interaction Design

Practical Approaches for Interdisciplinary Interaction Design

Authors: Adriana-Mihaela Guran, Daniela-Maria Andrei
( 10 downloads)
Abstract

In this paper the evolution of software design methods is discussed with insights from the usability perspective. Usability is considered an essential factor in the success or failure of an interactive system, determining its acceptance or rejection. Although the software design methods are continuously evolving, as the user are considered essential stakeholders in the design process, there still can be notice shortages in the process of communicating between the users and the developers of the software solution. The paper presents the chronological evolution of design methods in parallel with the evolution of the usability concept, emphasizing the support provided by the design method for developing usable solutions. The article tries to correlate the software design approaches with the solutions provided by Human-Computer Interaction in order to improve the software design process. As the user centered design focuses on an interdisciplinary approach, the paper presents some practical methods of mixing the approaches from software engineering with methods provided by social sciences.

Abstract

Multimedia applications use special techniques to browse their own content such as hypertext and hypermedia. These two concepts provide for the users semantic alternative in accessing a multimedia document. A particular way of achieving the concept of hypermedia is hypervideo. The main difficulty for realize such a system is given the fact that video data has spatial feature as well as a temporal dimension that means it lasts in time. To implement a hypervideo system has to define many modules having specialized functions and that are going to communicate each other. Thus, the article presents a data structure adapted to manage the synchronization of user interaction events, according to the timeline of the video sequence and the objects in view, which received the event. Besides the particular data structure are also presented usual operations for its maintaining as well as to explore it in the hypervideo system context.

Keywords: hypertext, hypermedia, hypervideo, frame segment tree, video stream, interaction synchronization
