The growth of information technology has led to a significant expansion of the possibilities for storing, processing and presenting spatial data. This gave a new round of development to such a direction of cartography and geoinformatics as geovisualization. Interactivity and dynamics have become the main distinguishing features of modern maps, especially in the field of cartographic design, which now extend to the problems of human-computer interaction to ensure more successful analysis of geodata and the development of spatial solutions. The article examines the existing definitions of geovisualization and proposes its own version. The scheme and features of individual stages of geovisualization creation are considered. Typical tasks that need to be solved to create high-quality visualization of spatial data are formulated and their systematization is performed. On the basis of the mentioned above tasks and their specificity, the most promising areas of research in the field of geovisualization were identified.

Authentication is probably one of the main security processes that almost everybody has at one point used. Currently, the most widespread authentication mechanism is based on textual passwords, a well-established approach that, with the growth of users and services, has increasing and serious drawbacks. With the rise of high quality displays and more ergonomic human computer interaction mechanisms such as mice, touch-pads and touch-screens, graphical passwords are credited as a valuable replacement to old-fashioned passwords. In contrast to alphanumerical passwords, graphical authentication mechanisms promise greater memorability and usability. In this chapter, an overview of the state-of-art of this topic is presented, introducing some of the main schemes proposed in current literature. The issues and concerns related to security and usability, which still challenge the researchers in this area, are also discussed.

The Way

Cyberspace is the environment created during the experience of virtual reality. Therefore, to assert that there is nothing new in cyberspace alludes to there being nothing new about virtual reality. Is this assertion correct? Is virtual reality an exciting development in human-computer interaction, or is it simply another example of effective simulation? Does current media interest herald a major advance in information technology, or will virtual reality go the way of artificial intelligence, cold fusion and junk bonds? Is virtual reality the best thing since sliced bread, or is it last week's buns in a new wrapper?

Análise, a partir de revisão de literatura em fontes secundárias, sobre as principais tendências que permeiam os estudos em interação humano-computador, com foco na realidade tecnológica no Pará. A pesquisa baseou-se em levantamento bibliográfico a partir de repositórios científicos digitais, sendo utilizados os verbetes interação humano-computador e Pará. O trabalho localizou duas principais vertentes de análise: inserção tecnológica em instituições de ensino no estado, e nos projetos e programas tecnológicos implantados no Pará a partir dos anos 2000. Percebeu-se, em ambas as vertentes, considerável ênfase em características ligadas a acessibilidade e acesso universal da informação, e de muitos dos projetos mostrarem informações preliminares ou indicarem descontinuidade. A pesquisa conclui que o estado do Pará, a partir dessas iniciativas, possui promissor campo de análise ligada à interação humano-computador, a partir de considerável espectro de programas de inserção computacional e informacional na região.AbstractThis study analyses the evolution and principal tendencies of research linked tohuman-computer interaction in technological reality of Pará. Data collection wasconducted in scientific repositories, using the terms Human-computer interaction and Pará. The research results in the recognition of two main issues: technological insertion in teaching institutions and technological projects implanted in Pará since 2000. It was noticed, in both aspects, considerable emphasis in accessibility and universal access, and also perceived that these projects present discontinuity and only preliminary information. This research concludes that the state of Pará has a promising field of study related to human computer interaction, related to informational and computational insertion.

Users should be involved in information technology (IT) artifact development, but it is often difficult and rare, especially in the development of commercial IT artifacts for external use. This paper critically examines discursive construction of user involvement in academia and in the IT artifact product development industry. First, three academic discourses on user involvement are identified. Then, discursive construction of user involvement is explored in four IT artifact product development organizations, in which user involvement is indirect and labeled as usability work. Five discourses on usability work are identified. They are related to the academic discourses on user involvement, and some of them are criticized (Asaro, 2000) as“forms of technological colonialism,” merely “silencing the users” instead of “giving them a voice.” It is recommended that especially the human-computer interaction (HCI) community should carefully reflect on what kinds of discourses on user involvement it advocates and deems as legitimate.

Computer Interaction

The use of Information Technology applications in almost all the sections of the society became one of the common practices in the society. Education, health, government, business, commerce, environment, and other areas, IT and Computing are plays a leading role. The Information Technology is also changing its shape and expanding its components every day. The latest in the list are Cloud Computing, Green Computing, Human Computer Interaction, Big-Data, Analytical Tools, and parallel computing. In the Government sectors, these technologies have valuable contribution and the magnitude of such contribution is increasing day by day. In the MGNREGA project, India, huge amount of information and computers are used and here these emerging technologies may be applied based on requirement and need. This paper discusses the potential applications of Cloud Computing, Big Data. Human Computer Interaction and Parallel Processing to improve the magnitude and speed of information processing in this rural employment project, which is officially termed as MGNREGA (Mahatma Gandhi National Rural Employment Guarantee Act, 2005).

Computer Interaction

Human-computer interaction (HCI) aims to design and develop high-usability interactive systems (ISs) focusing on users’ needs and ergonomic principles, among others. The usability of an IS refers to how easy it is to use and to learn. Similarly, software engineering (SE) aims to design and develop high-quality ISs focusing on schedule, budget, communication, and productivity. The quality of an IS refers to how satisfied the system clients and/or users are, verifying whether the system is performing exactly what was requested.
