Hedge has evaluated the benefits of a tiltdown tray system in several laboratory and field research studies. In the latest study, Hedge and Honeywell ergonomist Daniel McCrobie studied more than 50 professional office workers in their own workplaces in Arizona.
Hedge's team first recorded the motions of each worker as they worked at the computer in their current work environments. The data was gathered with state-of-the-art biomechanical measuring equipment and translated into dynamic records. In addition, one member of the research team evaluated the posture of each individual while typing and noted the workers' personal assessments of their level of comfort while working.
The team then provided one group of workers with preset-tiltdown keyboard trays for their computers and left. A few weeks later, the researchers returned and monitored the groups (test and a control group who had not been asked to change their habits) again. These observations were then compared with those from the first visit.
