ABSTRACT
Any use of computer soft ware to solve engineering problems is called computer-aided engineering, and has become one of the most important tools for simultaneous engineering. Fast, high-quality computer graphics now allow us to render lifelike images of people performing a multitude of tasks within various computer-aided engineering programs. Th us, it now is possible to position and move manikins to predict the performance capabilities of designated groups of people within a computer-rendered environment. Digital human modeling tools (DHM tools) have been introduced in industry to facilitate a faster and more cost-effi cient design process. Most of the tool users are in the fi elds of automotive and aerospace engineering. Th e tools are applied in the design, modifi cation, visualization, and analysis of human workplace layouts and product interactions.
