Virtual Reality Immersion: An Important Tool for Diagnostic Analysis and Rehabilitation of People with Disabilities

This paper sets out the case for the importance of using virtual reality immersion for diagnostic analysis and rehabilitating people with disabilities. To do so, a review of the literature was undertaken by examining articles published between 2000 and 2012. The results show that browsing in virtual immersion environments simulates real-world situations, with the advantage that this enables there to be full control over the variables analyzed and consequently over the health aspects involved. Furthermore, when using multisensory channels, the human-task-system interface tools enable there to be simultaneous treatment of multiple morbidities, which characterizes there having been an important advance made in the functional independence of people with disabilities.

What’s the benefit of problem exploration?

Models of the design process often start with activities of problem exploration before generating ideas, but the benefits of exploration have not been properly investigated. We did an experiment with undergraduate industrial designers during a design course. Except for the exploration methods, all teams had to follow the same design process. We observed that exploration methods increased the design teams’ perceived knowledge about the problem, but no impact on the quality of their final designs was seen. This challenges a widely held assumption about the value of problem exploration in design.

Design as a Tool for Managing Risks and Vulnerabilities Regarding Artifacts of Public Safety

It is on man’s interaction with the environment, taking into account all objects whether or not they are natural that design is focused. However, the relationship between the quantity and quality of what is produced and the creative processes of design do not always bring about the responses that the end user wants. This paper puts forward a proposal for designing a tool that may contribute to design methodologies for evaluating the safety of artifacts the use of which are restricted in the activity of Law Enforcement by Managing their Risks and Vulnerabilities. The paper sets out to include the knowledge of an expert in this subject area who is working on the risks and vulnerabilities that are present so as to obtain the most appropriate artifact possible for the demand proposed. The process of making such artifacts adequate and selecting them is permeated by such a large number of factors that they can only be matched, in amount, to the number of possible combinations between pieces of a chessboard. Hence the importance of producing a scale of values by using a rational and practical tool.

Ergonomic evaluation of usability with users: application of the technique of cooperative evaluation

This paper presents the application of a cooperative evaluation, technical evaluation performed ergonomic usability with users in the Learning Management Systens (LMS) used at the Instituto Federal de Pernambuco (IFPE). The data collected in the assessments were analyzed with users from Nielsen usability heuristics. The results showed that the environment has evaluated a large number of usability problems.

The design in the development of exergames: a new game for the contribute to control childhood obesity

Obesity is increasing alarmingly worldwide, especially in childrens audience, due to the adoption of sedentary habits. The exergames are a new class of digital games that have arisen over the possible use of technology, low cost, to unite physical activity to video games such as Nintendo Wii, X-Box 360, among others. And these have been gaining ground due to immersion of users, working their cognitive skills, attention and memory. This study presents a new game, the PEGGO developed by Federal University of Pernambuco, with data supporting the use for this type of game in order to contribute to help control childhood obesity.

The methodological involvement of the emotional design and cognitive ergonomics as a tool in the development of children products

To demonstrate the relationship between design and emotional development for kids, this article offers an initial approach about the definition and historical aspects of emotion in product development, citing the main authors of this issue. Based the field research conducted with children from 2 to 6 years of age, was also describes the basic ideas of Piaget in the child psychology and pre-operational stage (age group studied) and the significance of childrens toys from the perspective of Vigostsky. Using this theoretical framework and results of field research, we can infer some emotional design as advocated by the producers of positive affect on humans and its relationship with the childs development and choices of their toys.

Manual bamboo cutting tool.

The paper presents the development of a cutting tool guide, specifically for the harvest of bamboo. The development was made based on precepts of eco-design and ergonomics, for prioritizing the physical health of the operator and the maintenance of the environment, as well as meet specific requirements of bamboo. The main goal is to spread the use of bamboo as construction material, handicrafts, among others, from a handy, easy assembly and material available tool.

The Limited Rationale in Decision Making, Impacts on the Evaluation of Artifacts in the Design Process

Would the user able to make decisions rationally? If not, how, then, are your decisions actually made? What happens if the decision is made on the basis of intuition? Situations involving judgment and decision-making are daily in the lives of human beings, including in matters of consumption. The judgment and decision-making are complex functions that imply in the analysis of the characteristics of each of the options for a particular decision-making task, as well as the estimation of the consequences of the choice to be made and the origin of these studies is Microeconomics. In cognitive psychology, decision-making studies have been devoted to investigating how human beings make decisions in reality, not following rules, but seeking rationality within limits. This article aims to bring to light some discussions that elucidates more clearly how these decision making processes can be efficient.

User’s Behavior Under Review: The Use of Instrument’s to Evaluate Perception of Users

Considering that the process of perception is directly linked to the previous experiences of users, there is an entire process of selection, organization and interpretation of data that requires attention and dedication. This article, from a doctoral thesis, highlights that during the design process, it is necessary that there is respect for the perception of individuals who will use or evaluate the products or services offered. Thus, we used objective and subjective tools to evaluate the perception of users in a service field, in order to identify whether these results tend to the same or not, and from that, how does the identification of problems and solutions to facilitate the user’s own understanding. A cross-sectional observation study with 1 evaluation and 2 reevaluations, with 31 users in the physiotherapy area, was carried out in a SUS (Unified Health System) outpatient clinic, in which they were initially interviewed and followed by a subjective self-assessment of strength and function and an objective measure of force in the three moments. With this it was possible to observe that, when the user does not know the service and/or the product, one cannot have the correct perception of these, demonstrating how important it is to evaluate the perception of the individuals in general.

Management of Public Safety Artifacts Through Design

The relationship between quantity and quality of what is produced and its creative processes do not always bring the desired responses for the end user. The objective of this work is to develop a project tool that can contribute in design methodologies for safety assessment of artifacts for restricted use in the activity of Public Safety through Risk Management and Vulnerability. Sought the insertion of the knowledge of an expert in the subject area working the risks and vulnerabilities present to get an artifact the best possible demand draft. Hence the importance of producing a range of values through a rational and practical tool.
