UNLABELLED Repetitive pipetting is a task that is associated with work-related musculoskeletal disorders of the hand and arm. OBJECTIVE The purpose of this study was to evaluate the usability and ergonomic performance of commercially available pipettes as determined by user ratings and objective measurements. PARTICIPANTS Participants were laboratory technicians and scientists at the Lawren...

There are currently automatic evaluation tools the purpose of which is to implement the knowledge gained by ergonomics experts, with a view to enabling nonexperts and particularly user interface designers themselves to carry out this evaluation. Capturing the description of the User Interface to evaluate automatically this interface is one of the main objectives of these automatic evaluation to...

In this study, the authors evaluated the psychophysiological effects of video games on users. Although video games affect users in various ways, this study focused on the shortterm and direct effects. In an experiment, subjects played five kinds of video games on portable game machines for fifteen minutes. While each subject played a game, the authors measured the potential skin reaction during...

BACKGROUND The shape of laparoscopic instrument handles can cause physical discomfort. This problem may be ascribed to a lack of standards for instrument design. In this study, new ergonomic requirements for the design of laparoscopic dissection forceps were created. Three representative handles (a Karl Storz [click-line] scissors handle, an Access Plus scissors handle, and an Aesculap cylindri...

In this paper, we present a set of graphical controls intended for the coupling between the design and the evaluation of mobile user interfaces. It is a contribution to user interface early evaluation. The presented controls include mechanisms aiming to inspect their consistency according to a predefined set of ergonomic guidelines. We also report on the proposed approach current implementation...
