Gesture-based teleoperation using a holonomic robot

This work presents the development and integration of an user interface (UI) framework based on various current input devices that take advantage of our ergonomics. The purpose is to teleoperate a holonomic robot using upper member gestures and postures for studying the suitable of such interfaces when programming and interacting with a mobile robot. As performance vary from UI to UI the framework is focused to be used as a complementary industrial or didactic tool thus, changing how inexperience users tackle their first impressions when working with mobile robots while performing simple gesture-based teleoperation tasks. © 2012 ICROS.

A importância da motivação em sala de aula e sua relação com a aprendizagem

This paper was developed with students of the second year from high school, in a private school, identifying their motivation for the study of physics contents, when they are discussed in an not ordinary class, but critical. We incorporated the critical class as a didactic tool, able to stimulate and motivate the physics study and to help the teacher. Through questions, we evaluated how this class motivated the students, as well as how we investigate the type of class and teacher the students consider to be the most motivator for their learning

Metodologia de ensino jigsaw em disciplina de química medicinal

In this paper, we describe an educational experience involving the use of the jigsaw method on the Medicinal Chemistry course at the University of São Paulo, Brazil. The goal of this proposal was to investigate acceptance and contributions of the method to undergraduate chemistry teaching. Feedback on the jigsaw method collected from the focus groups and questionnaires showed that participants generally acknowledged the advantages of the jigsaw method in helping them learn the Medicinal Chemistry subject. Suggestions for improving the jigsaw method were also received from participants.

Tele-education environment and didactic iconography in sexual transmitted diseases

The field of advertising has developed techniques of mass communication and rapid transmission of information. Among these techniques are slogans and iconographies. This work used such tools for educational purposes and was divided into three modules. Module 1 evaluated the use of simplified textual communication (slogans) about the subject Sexually Transmitted Diseases. It was applied to third-year medical students, which had not taken the course on this theme. To evaluate the impact of the textual communication form (slogans), long phrases were elaborated in scientific language containing 15 topics. From these long phrases, compact phrases were developed using techniques of the advertising area for elaboration of slogans. Three forms of didactic material about that theme were developed. The first form consisted of long phrases in descriptive topics, using scientific language. The second was constituted exclusively of compact phrases in the form of slogans, and the third was composed of the combination of the two previous forms. Then, 10 multiple-choice questions were elaborated and applied in two phases. In the first phase, application occurred immediately after the reading of didactic texts; in the second phase, it happened 60 days after the reading. For statistical analysis, Snedcor's F test was used for analysis of variance, at 5% significance level. There was an increase in memorization by students who read the material containing the association between long phrases and slogans, which indicates that the latter, when used as an auxiliary model of learning, can bring significant benefits for education. Module 2 consisted of analyzing the elaboration of educational videos produced in graphic computing (called iconographies) for development of dynamic communication means. The theme Hair Cycle was utilized. Viability of high quantities of information in few minutes of animation could be demonstrated together with the advantage of presenting the process in a dynamic form without wasting scientific details. Module 3 presented the inclusion of slogans in educational videos produced in graphic computing about the Hair Cycle, showing a new tool for rapid and efficient transference of data. Slogans and iconographies, when utilized in educational material, can bring significant benefits for the student's learning.
