Abstract

The recognition of the users’ emotional states is a subject of interest concerning the human-computer interaction, as it conforms to the concept of natural interaction. The elimination of every constraint regarding the human-machine communication is one of the objectives of the nowadays research in the domain: the aim is that of making the machine invisible to the user. The body language, consisting in the body position and gestures, is one of the non-verbal, indirect means for emotion expression, besides the face expression and voice tonality. The computer-vision specific methods provide efficient, low cost techniques for emotional state recognition based on body position, respectively on human gestures, in the context of human-computer interaction. We study the problem of emotional state recognition based on body language, through computer-vision techniques. First, the nowadays knowledge in the domain is studied, and then the proposed solution is applied, consisting in image skeletonization and supervised classification.

Abstract

Cancer registry is an informational system for acquiring, managing and analyzing information about neoplazic disease persons. Its purpose is to provide accurate information about cancer occurrence in a particular geographical region. In this paper we present a proposal for the architecture of a multiagent system for national cancer registry. One of the main concerns in developing the system was its usability, that is why we have applied a task-based design, using GTA method and interviews and observation, in order to gather valid information for the future users.

An Ontology-Based Competence Management Interactive System For It Companies

An Ontology-Based Competence Management Interactive System For It Companies

Authors: Cristina NICULESCU, Ştefan TRĂUŞAN-MATU
( 10 downloads)
Abstract

The paper presents an interactive information system for competence management based on ontologies for information technology companies. 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 inferences may be performed in our approach by a reasoning engine, using classifiers in the Descriptions Logics tab associated with the Protégé ontology environment. 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. Starting from base-concepts, the user can get specific information about any instance or concept. The paper also presents some use-cases and further developments.

Abstract

One of the main problems in designing interactive systems is to make it usable. This means you have to know the users and their needs and expectations. Software engineering approaches in building interactive systems does not support these aspects related to users. That is why, the methods used by social sciences can be adapted in order to provide the needed information about users. In this paper we present some of the methods used by social sciences that can be helpful in requirements analysis and usability evaluation. These methods have been successfully applied and some case studies are also presented.

Critical Remarks On The Interaction Of Users With File Systems

Critical Remarks On The Interaction Of Users With File Systems

Authors: Lucian Cheţan
( 10 downloads)
Abstract

Every major operating system stores data by means of hierarchical file systems. Easily understood by users, this form of organizing data has remained basically the same since its inception, but is unable to effectively organize large quantities of personal files, such as music, documents, etc. A new approach is necessary, one that builds on top of existing functionality. The solution consists in the implementation of virtual file systems—metadata-centric file systems that allow adding meaning to data. This leads to a more intuitive way of managing personal files: searching, previewing and meaningfully displaying data in graphical user interfaces. The article presents an overview of such file systems, and how the graphical user interfaces must reflect the new capabilities. At the end, the article suggests new ways of bridgind the gap between locally stored data and Internet data, whose goal is to ultimately create a more satisfying user experience.

Visio-Haptic Simulator for Static and Kinetic Friction

Visio-Haptic Simulator for Static and Kinetic Friction

Abstract

3D simulations augment the presentation of abstract concepts by enhancing our understanding. However, most simulations only make use of two of our five senses: sight and hearing. If we employ additional sensory communication channels in these simulations, we may gain a deeper understanding of illustrated concepts by increasing the communication bandwidth and providing alternative perspectives. We present the implementation of the sense of touch in 3D simulations for teaching important concepts from introductory physics. Specifically, we have developed a visuo-haptic simulator that illustrates friction. We hypothesize that interactive 3D haptic simulations are useful for engaging students in subject study and allowing them to put into context the material presented.

Integrating 3D Scene in Interactive Graphics Applications

Integrating 3D Scene in Interactive Graphics Applications

Abstract

Building and using tridimensional geometric models in computer applications imply great efforts in production software application. A model contains both complex geometry and properties such as color, lighting, texture, material. Unlike a 2D image, a tridimensional model brings with it a perfect precision. Today, 3D modeling software allow to build, view and modify models as if they were real objects. If one wants to view such models but in a different application context, other than modeling, the only solution remains the import and presentation of these models in the context of the main application. Thus, a primary objective of this article is to integrate the 3D scene built with specialized programs in graphical applications written in C++, C # and Java in a interactive, dynamic context using OpenGL and Java 3D. The choice of these programming languages has been determined by their market domination in the demand and supply ofcompetences. The second objective is to provide interactivity with a 3D scene objects in a C++, C# or Java application context. The article also presents a solution for the deployment and integration of 3D Studio Max scenes in C# applications using OpenGL.

Abstract

The interaction between the visually impaired user and the assistive technology offered the possibility to structure a new professional and educational approach, very much in conformity with the present social system's requirements. Nonetheless, we must take into consideration also the personality traits involved in this interaction and the changes that occur consequently to this interaction. In this article, we wanted to present a synthesis of the research already undertaken at a national level in the past few years and also to present the main conclusions from a technical, occupational and educational perspective, along with future research paths in the field of the interaction between the visually impaired user and the assistive technologies, which impose themselves on medium and long term in our country.

An Intra and Inter-Topic Evaluation and Cleansing Method

An Intra and Inter-Topic Evaluation and Cleansing Method

Abstract

Topic modeling is a growing research field and novel ways of interpreting and evaluating results are necessary. We propose a method for evaluating and improving the performance of topic models generating algorithms relying on WordNet data. We first propose a measure for determining a topic model’s fitness factoring in its broadness and redundancy. Then, for each individual topic, the amount of relevant information it provides, along with its most important words and related concepts are determined by defining a cohesion function based on the topic’s projection on WordNet concepts. The model as a whole is improved by eliminating each topic’s outliers with respect to the ontology projection. We define a inter topic ontology based distance and we further use it to investigate the impact of removing redundant topics from a model with regard to the overlap between topics’ ontological projections. Clustering similar topics into conceptually cohesive groups is tried as an alternative to pruning less relevant topics. Results show that evaluating and improving statistical models with WordNet is a promising research track that leads to more coherent topic models.

Abstract

This paper focuses on the relation between the main concepts used in Human-Computer Interaction domain in order to study users’ perception of interactive products quality like usability, satisfaction, and user experience. In order to achieve this goal, we have proposed a reseach that verifies the psychometric qualities of the instruments used to measure the above mentioned concepts. Three such instruments have beean translated and adapted for romanian users – AttrakDiff 2.0., Questionnaire for User Interaction Satisfaction şi Software Usability Measurement Inventory. These instruments have been filled in by 213 users of the web site www.psychology.ro. The obtained results show that there are some deficiencies of the scales construct validity.

Abstract

Nowadays, the e-learning applications are integrated in most of curricular areas and scholar cycles. In this context, the perceived utility of these applications at end-user level is an important issue. A series of theories and models (Technology Acceptance Model - TAM, Innovation Diffusion Theory – IDT, Student Integration Model - SIM) have been developed regarding the acceptance of informatics technologies in general and the e-learning technologies in particular. This paper is focussing on the main aspects of the acceptance theories and models in the context of e-learning applications.
