Interactuar con la tecnolog´ıa de forma human´ıstica ya no se limita a las pel´ıculas futuristas o a los centros de investigaci´on de alto nivel. Cada vez es m´as habitual que la tecnolog´ıa incorpore el reconocimiento facial, de voz, de gestos y de objetos, ofreciendo a los usuarios diversas formas de interactuar. En particular, los movimientos co...

En tiempos donde algunos dicen que ChatGPT podría cambiar la programación, es importante instruir correctamente a los estudiantes sobre su existencia y sus capacidades. Adicionalmente, el incluir tópicos actuales dentro del contenido curricular revela una forma de destacar y diferenciar dichos contenidos para llegar a los estudiantes de una forma d...

Sustainable Development Goal 4 from the United Nations 2030 Agenda, focus on ensuring inclusive and equitable quality education and promoting lifelong learning opportunities for all. Inclusive education is a key component of sustainable development goal 4, and assistive technology is a critical factor in achieving it. In this context, this paper in...

From the beginning of the COVID-19 pandemic, the severity and prevalence of symptoms of psychological distress, fatigue, brain fog, and other conditions have increased considerably, including among people who have not been infected with SARS-CoV-2. Many studies summarize the effect of the pandemic on the availability of mental health services and h...

La popularización y expansión de Internet y las Nuevas Tecnologías de la Información y la Comunicación han modificado la vida de las personas en diversos aspectos. La educación no se ha mantenido al margen de esta revolución tecnológica. En este sentido, la Realidad Virtual (RV) y la Realidad Aumentada (RA) son alternativas prometedoras para dar so...

Documentation of institutional biological collections are essential for scientific studies and conservation of the biodiversity of a region. In particular, preserved specimens require the development of a short- and long-term plan to prevent damage. In this context, the 3D digitisation of this type of documentation provides innovative mechanisms to...

Computational Thinking (CT) represents a possible alternative for improving students’ academic performance in higher level degree related to Science, Technology, Engineering and Mathematics (STEM). This work describes two different experimental proposals with the aim of introducing computational thinking to the problem solving issue. The first one...

Currently, there are many applications like human-computer interactions in which speech technology plays an important role. In particular, embodied conversational character interfaces research has produced widely divergent results and it has tended to focus on the character’s dialog capabilities associated with reasoning. Conversely, the present wo...

Despite the known health benefits of regular participation in physical activity people still refuse this practise. Nowadays, Virtual Reality (VR) is a very powerful and compelling computer tool by which humans can interface and interact with computer-generated environments. In this paper, we propose a virtual training system which can be customized...

Nowadays, serious games are one of the biggest existing industries and it is still growing steadily in many sectors. Particularly, the use of virtual worlds and serious games in education is growing. This paper introduces the development of a serious game in an immersive learning environment for teaching Civics. The work’s idea is to develop a game...

In virtual environments, virtual hand interactions play a key role in interactivity and realism allowing to perform fine motions. Data glove is widely used in Virtual Reality (VR) and through simulating a human hands natural anatomy (Avatar’s hands) in its appearance and motion is possible to interact with the environment and virtual objects. Recen...

Since the emergence of more sophisticated interaction devices, Human Computer Interaction (HCI) science has extended in all forms, where Non-Verbal Communication (NVC) is one of added issues. In this context, the use of gestures (actions expressed by body, face, and/or hands) as a natural solution for applications that require hands-free and no tou...

urrently, there are many applications like human-computer interactions in which speech technology plays an important role. In particular, embodied conversational character interfaces research has produced widely divergent results and it has tended to focus on the character’s dialog capabilities associated with reasoning. Conversely, the present wor...

This article describes the Computer Graphics and Vision research that are being developed by three universities’ laboratories in Argentina: III-LIDI Institute of Computing Research at National University of La Plata, VyGLab Visualization and Computer Graphics Laboratory at South National University, and CGLab Computer Graphics Laboratory at Nationa...

In the last decade, virtual reality (VR) systems have been used to enhance the visualization of design projects. The VR techniques allow to the designer interacting and modelling in a more intuitive and e cient way. Current 3D and animated simulation tools are a new chal- lenge for 3D visualization. In this paper we propose a general VR com- puting...

This paper presents a tool for simulating the traditional Sgraffito technique through digital image processing. The tool is based on a digital image pile and a set of attributes recovered from the image at the bottom of the pile using the Streit and Buchanan multiresolution image pyramid. This technique tries to preserve the principles of artistic...

Image mining deals with the study and development of new technologies that allow accomplishing this subject. A common mistake about image mining is identifying its scopes and limitations. Clearly it is different from computer vision and image processing areas. Image mining deals with the extraction of image patterns from a large collection of image...

The T-GaME L3 project (Teaching computer Graphics and MultimEdia LifeLong Learning, http://t-gamel3.ub.edu.ar) intends to provide a learning environment for computer graphics and multimedia contents mainly focused on the domains of computing and architecture. It is based on the cooperation of several higher education institutions from Europe and La...

Minix is a Unix clone Operating System, designed by Tanembaum ([2],[3]) to allow beginners to do practical training in Operating Systems area.In this context the present paper describes the work done by a group of students implementing alternative process schedulers disciplines and their evaluation comparing performance estimates.Some unexpected de...

Minix is a Unix clone Operating Systems to be run on IBM PCs and compatibles, designed by Tanembaum [10] for courses in the area.Accepting the Tanembaum's proposal, this document describes the results of some extensions on the internal work of Minix as an exercise on Operating Systems Design and Implementation that attempts to transfer that experie...

Importance driven half-toning (IDH) presents a method for reduced resource rendering of gray scale images. This approach uses an image pyramid to distribute drawing primitives to different areas of the image based on an importance function. The original paper showed how a wide variety of effects can be achieved using a combination of importance fun...

T-GAME Project integrates the academical achievement of eight European and Latin American universities in order to design a series of interdisciplinaries courses, related to computer graphics, to be assumed in new standard and post grade plans of study by those universities.

The T-GAME L3 project intends to establish the possibility of cooperation within institutions focusing activities in the realm of continuous development in the area of Digital Graphics by making use: of new technologies, methods and learning processes related to half-time distance and total distance teaching. The programs offered will be customized...
