Ramsis – The Leading Cad Tool for Ergonomic Analysis of Vehicles

An algorithm for both human-like motion generation and joint torques computation for digital humans is addressed in this paper. This goal has been achieved using techniques derived from robotics. In particular, the so-called augmented Jacobian has been used to solve the inverse kinematics problem with a single closed loop inverse kinematics algorithm. Furthermore, a position control for the center of mass of the kinematic chain, and for its projection on the support plane (center of pressure), has been implemented to achieve easy posture control. Thus, the inverse kinematics can be solved taking into account the static balance of the digital human. Moreover, the proposed algorithm allows simulating quite complex tasks, which involve the motion of the whole body, by means of only few task-related control points arbitrary located on the whole kinematic chain. The resulting movements are quite natural even for complex tasks as can be seen on the simulation experiments reported which show the effectiveness of the proposed approach. Finally, the joint torques can be computed thanks to the kinetostatics duality: the results are in accordance with biomechanical analyses

“…The digital human model "RAMSIS" [7] in its original state addressed demands on ergonomics, comfort and safety. It is a well-accepted tool in the automotive industry and one of the most used digital human models [8]. With the enhancements from VERITAS, ergonomists are enabled to use virtual user models with parameterized disabilities.…”

“…Another tool using virtual environments for ergonomic analysis is the VR ANTHROPOS [2], which simulates the human body in the virtual environment realistically and in real time. There are also many tools such as JACK [72], RAMSIS [87], SAMMIE [74], HADRIAN [53], SIMTER [51], Safework [25], and Santos TM [89], offering considerable benefits to designers looking to design for all, as they allow the evaluation of a virtual prototype using virtual users with specific abilities. A list of software tools for ergonomics analysis is reported in [23].…”

The use of user models can be very valuable when trying to develop accessible and ergonomic products and services taking into account users specific needs and preferences. Simulation of userproduct interaction using user models may reveal accessibility issues at the early stages of design and development, and this results to a significant reduction in costs and development time. Moreover, user models can be used in adaptive interfaces enabling the personalised customisation of user interfaces that enhances the accessibility and usability of products and services. This paper presents the efforts of the Virtual User Modelling and Simulation Standardisation VUMS cluster of projects towards the development of an interoperable user model, able to describe both able-bodied and people with various kinds of disabilities. The VUMS cluster is consisted by the VERITAS, MyUI, GUIDE, and VICON FP7 European projects, all involved in user modelling from different perspectives. The main goal of the VUMS cluster was the development of a unified user model that could be used by all the participant projects and that could be the basis of a new user model standard. Currently, within the VUMS cluster, a common user model has been defined and converters that enable the transformation from each projects specific user model to the VUMS user model and vice versa have been developed enabling, thus, the exchange of user models between the projects
