Design de interface do ambiente virtual HyperCAL online

Abstract

A presente pesquisa objetiva propor uma metodologia que oriente o projeto de interface de ambiente virtual centrado no usuário que seja sistematizada como processo de produto com princípios de design de interação, considerando aspectos de usabilidade e ergonomia, de modo a favorecer o trabalho do usuário, permitindo a apropriação do conteúdo e a execução das tarefas através das funcionalidades do sistema. Para consecução do trabalho foram investigados: os elementos da experiência do usuário; as ferramentas de planejamento de produto; as técnicas engenharia de software; e os conceitos do design de interação. A validação da metodologia foi feita através do projeto de interface do módulo do desenvolvedor (professor/instrutor) do HyperCalGD online. A interface projetada apresentou melhores condições para o desenvolvimento de materiais educacionais.

Assessment of the usability of a digital learning technology prototype for monitoring intracranial pressure

“…Thus, one of the important contributions made by the evaluators was to point out usability problems at the interfaces, which could confuse or distract users, suggesting significant changes to address the problems found. Other studies revealed similar suggestions, such as: insert explanations of charts and images that may not be entirely clear 15 , 25 , a scroll-bar for long texts 25 , changing the color of the interface 9 , 15 to light green, standardized links 25 , including an error message when users do not correctly fill out the registration screen, stopping wherever the error occurred 16 , and a page describing the icons 25 . In one study evaluating learning technology, evaluators had problems identifying some of the icons 7 , demonstrating how important it is that they be fully intuitive.…”

“…Usability problems related to these heuristics can reduce the interaction between the system and its users. Therefore, designers must pay attention when designing interfaces, making sure they are intuitive and easy for even an inexperienced user, avoiding additional effort in learning to use the system 25 .…”

“…Interfaces and content must be simple, and expressed in clear and objective language that is easy to understand 11 , 25 . In one study, the evaluators suggested less content on each page, and that content be arranged by topic.…”

“…A user-friendly interface may include buttons to make it easier to use. Buttons are used to select items or actions, and should be described using verbs 25 . Here the evaluators suggested a button for users to increase or decrease font size, a button at the footnote to turn off the sound, and a button for printing.…”

“…The least violated heuristics were "recognition rather than recall" no error message on the registration page and document support. There is no help item on the pages, and violations related to these heuristics may lead users to an incorrect interpretation of the actual action desired, leading to useless effort, cognitive overload, frustration and dissatisfaction ( 20 - 21 , 25 ).…”
