The ergonomic design of workplaces or accommodation as well as the manageability of the different facilities on ships become more and more important for the customer. During the construction process ergonomic analyses are rarely carried out. Consequently, the expense of time and costs on modifications during testing is rather high. Currently, examinations are made mostly with the help of models or static model dolls in CAD.
The aim of the project was the integration of a human model in order to realistically evaluate ergonomics and manageability of ships. Therefore, an ergonomic human model was put into a virtual reality environment, and the respective tracking tools were examined. With the help of these tracking tools individuals and their movements can be observed. The poses gained from this observation can then be transferred on any anthropological model in real time. In this case, the software platform RAMSIS, provided by the company Human Solution, serves as a human model and the software InstantReality, provided by Fraunhofer IGD, serves as the virtual reality environment.
In the project experts also examined how a workplace for ergonomic examinations may look like in the future. Through the use of a suitable ergonomics tool examinations can be made in an early phase of construction and thus costs for modifications during testing can be avoided.
Within the framework of ergonomic considerations the system allows the following analyses:
Collision analyses (highlighting of colliding elements by different colours)
Load analyses (consideration of maximum forces, avoidance of harmful body positions and excessive workloads)
In the development of the ergonomics tool the following issues are especially taken into consideration:
Simple display of the load analyses
Protocols of results and motion paths
