Manual analysis and optimisation of ergonomic parameters can be tedious when process and worker's body size variance is high. Automating this process would reduce workload and enable developing assistance systems for worker support. This paper presents a system which computes the positions of the parts of the body from input depth images and assesses ergonomics scores. The method is based on Particle Swarm Optimisation (PSO). By parallel processing on graphics hardware (GPU), the system is able to provide ergonomic feedback within a few seconds.
