Digital human models can be used for biomechanical risk factors assessment of a workstation and work activity design for which there is no physical equipment that can be tested using actual human postures and forces. Yet, using digital human model software packages is usually complex and time-consuming. A challenging aim therefore consists in developing an easy-to-use digital human model capable of computing dynamic, realistic movements and internal characteristics in quasi-real time, based on a simple description of future work tasks, in order to achieve reliable ergonomics assessments of various work task scenarios. We developed such a dynamic digital human model, which is automatically controlled in force and acceleration and inspired by human motor control and based on robotics and physics simulation. In our simulation framework, the digital human model motion was controlled by real-world Newtonian physical and mechanical laws. We also simulated and assessed experimental insert-fitting activities according to the occupational repetitive actions (OCRA) ergonomic index. Simulation led to satisfactory results: experimental and simulated ergonomics evaluations were consistent, and both joint torques and digital human model movements were realistic and coherent with human-like behaviours and performances.

“…6) instead of a representative sample of real end users is used for validation, these substitutes have to be validated beforehand as well. These validated user dummies are already partially delivered by the following research contributions: cognitive and mental modelling [129], human factors [130], artificial intelligence [131] and humanoid robotics [132]. Research in this direction led to tools like AMME [133], HOMER [134], or IMPRINT [135].…”

Abstract-One of the major challenges in the emerging interdisciplinary field of human-computer interaction (HCI) is the specification of a research line that can enable the development of validated design knowledge with a predictive power for the design of interactive systems. Based on the three different elements in the design of interactive systems: (1) human being(s), (2) technical artefact(s), and (3) context of use, different academic disciplines contribute with different research paradigms to this new field: social sciences with a strong empirical and experimental approach, industrial and interaction design with a strong emphasis on artistic design, and engineering disciplines with a strong technical and formal approach. This programmatic paper presents, discusses and recommends a possible way to integrate the strengths of different research and design paradigms based on triangulation, and we argue for HCI as an engineering discipline.Index Terms-human computer interaction, design paradigm, research agenda, triangulation.

“…In order to evaluate the physical (biomechanical) aspects of working conditions, several software packages have been developed to facilitate ergonomic assessment, such as SAMMIE [55], JACK [4], Ergoman [59] and SANTOSHuman [69,68]. Simulations computed with these software packages usually rely on kinematic animation frameworks.…”

A human-like learning control for digital human models in a physics-based virtual environment

et al. 2014

This paper presents a new learning control framework for digital human models in a physicsbased virtual environment. The novelty of our controller is that it combines multi-objective control based on human properties (combined feedforward and feedback controller) with a learning technique based on human learning properties (human-being's ability to learn novel task dynamics through the minimization of instability, error and effort). This controller performs multiple tasks simultaneously (balance, non-sliding contacts, manipulation) in real time and adapts feedforward force as well as impedance to counter environmental disturbances. It is very useful to deal with unstable manipulations, such as tool-use tasks, and to compensate for perturbations. An interesting property of our controller is that it is implemented in cartesian space with joint stiffness, damping and torque learning in a multi-objective control framework. The relevance of the proposed control method to model human motor adaptation has been demonstrated by various simulations.
