description This article presents the conclusions of an investigation whose objective was to characterize design attributes that allow creative and other interested parties to assertively develop a precision device used with the hands. In order to do this, usability techniques such as eye tests and traditional testing were taken into account, and were implemented in an exercise with forty users who tested five devices representative of precision hand-operated tools: screwdriver, pen, key, brush and dispenser, by means of the execution of three processes: recognizing the object, doing a real task and controlled ones. It was concluded that people show a learning curve as they repeat the task requested, and that the configuration and morphology of the solids for the grip of the precise objects influences the performance of the same. Tools with complex morphologies showed more visualizations, while the proper design of the control system or handle of precision tools requires surfaces that are easy to identify and that resemble similar tools of everyday life.

Este artículo presenta las conclusiones de una investigación cuyo objetivo fue caracterizar atributos de diseño que permitan a creativos y otras partes interesadas desarrollar asertivamente un dispositivo de precisión usado con las manos. Para ello, se tuvieron en cuenta las técnicas de la usabilidad como los test y el seguimiento ocular, y se puo en práctica en un ejercicio con cuarenta usuarios que probaron cinco dispositivos representativos de las herramientas de precisión operadas con las manos: destornillador, esfero, llave, pincel y dosificador, por medio de la ejecución de tres procesos: reconocer el objeto, hacer una tarea real y otras controladas. Se concluyó que las personas muestran una curva de aprendizaje a medida que repiten la tarea solicitada, y que la configuración y la morfología de los sólidos para el agarre de los objetos precisos, influye en el desempeño de las mismas. Las herramientas con morfologías complejas presentaron mayor cantidad de visualizaciones, mientras que el diseño adecuado del sistema de control o mango de las herramientas de precisión requiere de superficies fáciles de identificar y que se parezcan a herramientas similares de la vida cotidiana. Este artigo apresenta as conclusões de uma pesquisa cujo objetivo foi caracterizar os atributos de desenho que permitam a criativos e outras partes interessadas desenvolverem assertivamente um dispositivo de precisão usado com as mãos. Para isso, levaram em consideração as técnicas de usabilidade como os testes e o seguimento ocular, e colocaram em práctica em um exercício com quarenta usuários que experimentaram cinco dispositivos representativos das ferramentas de precisão operadas manualmente: chave de fenda, canaleta, chave, pincel e doseador, por meio da execução de três processos: reconhecimento do objeto, práctica de um exercício real e práctica de exercícios controlados. Concluiu-se que as pessoas mostram uma curva de aprendizagem à medida que repetem as actividades solicitadas e a configuração. Em outro parte da morfologia dos sólidos para fixaçao dos objetos precisos, influencia no desempenho das mesmas. As ferramentas com morfologia complexas apresentaram maior quantidade de visualizações, enquanto que o desenho adequado do sistema de controle o de uso manual das ferramentas de precisão requer superfícies fáceis de identificar e que pareçam as ferramentas simelhantes as da vida cotidiana.
