| סיכום: | 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. |
