Interface com o AEDROMO (Ambiente experimental e didático com robôs móveis) utilizando sistema Android

The AEDROMO (Experimental and Didactic Environment with Mobile Robots) is a versatile, user friendly and scalable environment that supports a wide range of experiments. In it there is an area that is similar to a desk where objects can interact with each other, including robots and other objects, and thus can perform numerous activities. In it's current state, AEDROMO has client computers that interact with the system through an interface, and thus realize the communication between the user and AEDROMO. This project offer support to create a new form of interface for AEDROMO and can therefore be used for devices running Android, the app developed in this project will serve as a basis for future work on this new interface

Desenvolvimento de aplicações Web com base em modelagem 3D: módulo Android

This project brings the development of an Android application which will allow users to access 3D models on web. The application developed allows Android devices to access web pages which have code that should use OPENGL to renderize. To demonstrate this functionality, an example web application was build, using technologies such as X3DOM and HTML5, which uses WebGL to get renderized. This web application gives to the user an environment of a virtual city, where he could surf by and interact with the objects. The Android application brings this immersion to the mobile world, also. The access and storage of data was developed a Webserver, which bring to the web application a simple API to give access to the database

Desenvolvimento de objeto de aprendizagem para dispositivos móveis explorando os sensores internos do sistema operacional Android

The traditional model of teaching little is modernized in recent decades. When in contact with this system, it is normal that the new-generation students feel unmo tivated in carrying out the proposed activities in the classroom. Considers Prensky (2001) these students, called Digital Natives, born with a modern way of thinking and learn and feel encouraged and motivated with activities that invite to interact. For this reason, it has been proposed the development of an object of learning in the form of application for Android tablets, exploring the internal sensors available in them, with the purpose of offering an interactive activity to students on the physical concepts involved in the process of photosynthesis in plants. For the construction, informational texts written in didactic language and easy to understand, illustrative images and animations were employed. In addition, we used the light sensor in the interactive activity on the process of photosynthesis so that the student could observe and understand how the environment is able to interfere with this process

Backpacks and school children's obesity: challenges for public health and ergonomics

This descriptive study of cross sectional has focused on analyzing the school material weight transported by students associated with children and adolescents overweight in primary and secondary schools. Participants 339 students of both genders, aged 10-19 years. 243 students carrying and average load of 12.65% of his body weight. 53 students were overweight with a BMI of 20,00 to 35,6. 20 overweight students carrying backpacks more than 10% of his body weight. 21% of the students rated complained of back and shoulder pain. This data is very important in the preventive aspects for the individuals studied, as well as others with the same anthropometric characteristics and the same demand.

Openability of soft drinks PET packagings

Studies on packaging accessibility are still incipient in Brazil. Many of these packagings can represent a challenge to users, whether due to non-informative labels, tricky tabs or seals, or even those that need strength to open. This paper brings a simple test to determine the necessary torque force to open PET bottles, and to predict the amount of users that could not open it. The findings suggest that a considerable amount of users could not open it or would have some difficulties to exert the necessary force.

Are cutout handles used when available in real occupational settings? Description of grips and upper extremities movements during industrial box handling

In order to achieve better postures and decrease musculoskeletal risks adequate design of hand/box couplings for manual materials handling (MMH) are still needed. No studies evaluating upper limb movement thorough direct measurements during box handling in workplace were identified in the literature. In this study we describe the types of grip and movements adopted by ten workers when handling redesigned boxes with cutout handles between different heights on industrial pallets. The new handles were used by 90% of the workers through different types of grip. Electrogoniometric measurements showed relatively safe forearm and wrist movements, although elbow inadequate range of movement was recorded. Despite the good acceptance of the cutout by workers, the new design requires extra internal space in the boxes reducing applications for this alternative of box.

Influence of door handles design in effort perception: accessibility and usability

The application of ergonomics in product design is essential to its accessibility and usability. The development of manual devices should be based on ergonomic principles. Effort perception analysis is an essential approach to understand the physical and subjective aspects of the interface. The objective of the present study was to analyze the effort perception during a simulated task with different door handles by Portuguese subjects of both genders and different ages. This transversal study agreed with ethical aspects. 180 subjects of both genders pertaining to three age groups have participated. Five door handles with different shapes were evaluated. A subjective numeric rating scale of 5 levels was used to evaluate the effort. For statistical analysis it was applied the Friedman non-parametric test. The results have showed no significant differences of effort perception in door handles "A" and "B"; "A" and "D"; and "D" and "C". Door handle "E" presented the lowest values of all. In general, there's an inverse relationship between the results of biomechanical studies and the effort perception of the same task activity. This shows that door handles design influence directly these two variables and can interfere in the accessibility and usability of these kinds of products.

Anthropometric aspects of body seated in school

This study aimed to assess the student-furniture interface from anthropometric parameters of the sitting posture. The sample was composed of 887 students from two public schools in the State of Parana - Brazil, which attended children from 7 to 17 years of age. The data collection used anthropometric measures of the sitting position, a questionnaire containing a human body diagram for indication of discomfort areas and photographic records to verify postural and ergonomic inadequacies in classroom. The following anthropometric variables were measured: popliteal height, sacro-popliteal length, hip width, lumbar support height, and elbow and thigh height. Percentiles 5 and 95 of anthropometric variables showed differences statistically significant, with variation coefficient greater than 30%. In relation to body discomfort, the highest occurrences were recorded for ankle, knees and shoulder joints as well as for spine and buttocks. It was concluded that children use school furniture that does not meet their anthropometric standards, which favored the adoption of incorrect postures and contributed to the emergence of musculoskeletal problems that can interfere with their educational process.
