  • Mannequin Properties Desired for Ergonomic Evaluation of Car Interiors
  • 1998
  • Konferensbidrag (refereegranskat)abstract
    • Mannequin properties desired for ergonomic evaluation of car interiors Lars Hansson, Kenneth Holmqvist, Simon Sjölander, Giovanni Distante, Guiseppe Andreoni, Nicholas Colford, Tomas Engström, Gert-Åke Hansson, Roland Kadefors, Patric Petersson, Camilla Rigotti, Lena Sperling, Anders Sundin, Per Östman, Roland Akselsson The aim of this study was to simulate a future mannequin with real people in order to find characteristics necessary for ergonomic evaluation of comfort in car interiors. We argue that the mannequin should ideally perform natural movements, collision detection, a biomechanical model, and eyes. Optional improvements to the mannequin involve muscles and a heart. We also discuss the user interface to the mannequin and means to present mannequin data.

  • Work and Work Place Design Using Empirical Shop Floor Information and Virtual Reality Techniques
  • 1997
  • Ingår i: IEA'97 "From Experience to Innovation". - Finnish Institute of Occupational Health, Helsinki, Finland. ; 2, s. 25-27
  • Konferensbidrag (refereegranskat)abstract
    • Work place design based on traditional ergonomic science has, to a large extent, been delimited by information collected from studies of individual human beings. This research approach has not been proven to influence industry shop floor work to an extent corresponding to what could be expected from research efforts (Winkel and Westgaard, 1995). Thus the practitioners are left to decide about the detailed work place design, neglecting scientific knowledge. The accelerating development within technical as well as social sciences, combined with the industrial development of production systems has, in fact, blurred the vision and method arsenal available for those interested in fitting the production system to the man. However, new prospects have, at the same time, been made available through expanding personal computer and Virtual Reality (VR) techniques implying untraditional analysis procedures for work and work place design as will be illustrated in this paper. The aim of this paper is to illuminate the feasibility of such a prospect using personal computer-,. video- and VR-techniques to amalgamate empirical shop floor information especially collected for design purposes with computer models of work. Two case studies, denoted case I and case II, will be shortly described from which an integration will be discussed.

  • Process Oriented Ergonomics - The Ergonomics of the Future? A Case Study of Integrated Ergonomics at an Engine Assembly Plant
  • 2000
  • Ingår i: Proceedings of the IEA 2000/HFES 2000 Congress. ; 5, s. 5-328-5-331
  • Konferensbidrag (refereegranskat)abstract
    • Ergonomics are, in most cases, focusing on the human being when evaluating assembly system designs. This results in the human performance being expressed isolated from the technical environment. On the other hand, technicians are prone to concentrate on the hardware. These conditions underline the need to pursue a more integrated evaluation and design procedure in order to avoid the drawbacks of these traditional approaches. In this paper, the authors propose an alternative approach, i.e. process oriented ergonomics, which might be a constructive way of tackling some of the more complex aspects of the man-machine interaction in industrial environments such as assembly of engines.

  • Annie, a Tool for Integrating Ergonomics in the Design of Car Interiors
  • 1999
  • Ingår i: Journal of Materials & Manufacturing. ; 108:5, s. 1114-1124
  • Tidskriftsartikel (refereegranskat)abstract
    • In this ANNIE project – Applications of Neural Networks to Integrated Ergonomics – BE96-3433, a tool for integrating ergonomics into the design process is developed. This paper presents some features in the current ANNIE as applied to the design of car interiors. A variant of the ERGOMan mannequin with vision is controlled by a hybrid system for neuro-fuzzy simulation. It is trained by using an Elite system for registration of movements. An example of a trajectory generated by the system is shown. A fuzzy model is used for comfort evaluation. An experiment was performed to test its feasibility and it showed very promising results.
