Handling consumer durables, equipment and tools means exerting forces through the limbs. Products for daily-life use by the many should in this respect not only be adapted to healthy young males, but also weaker users. In order to realize comfortable force exertion, a product-designer ought to know and take into account which weaknesses and strenths occur in the population. Unfortunately, only few and dispersed data exist on force exertion in user-product interaction. There clearly is a need for an "Atlas of Human Force Exertion" ,which would contain all existing information on human force exertion relevant to designers. In this study a survey is given of the relevant literature and of the many factors determining maximal, submaximal and comfortable force exertion. To investigate various aspects of the Atlas, several crucial experiments are carried out, on the effects of body posture, the use of one or more joints in the arm, endurance and discomfort. An overall analysis shows the inte rrelatedness of force and anthropometric data from different parts of the human body. It is indicated how to take force exertion into account when designing and how to apply data on force, and the feasibility of a force Atlas is demonstrated. This book is of theoretical and practical interest to designers, ergonomics, physicians and physiotherapists.
