Over the years approach focusing in ergonomics has changed. We still talk about identification - analysis - elimination of the risks on the workplaces. But differences are at the possibilities of modern ergonomics, movement of science and technical possibilities. The options of using a mobile applications, Internet of Things, data gathering and their real time evaluation and their sharing. We present those solutions that combine traditional knowledge and modern technologies. The results are innovative and advanced ergonomic tools based on Industry 4.0 concept. Electronic tools are a new direction in ergonomics. With the support of mobile applications we see a way to create healthy conditions at work for production and also non-production workers, assembly and logistics. At the beginning of 20-th century, majority of us had no idea what the ergonomics is, how many risks occur during our job that they are connected with the health of employees and have not known that special methods and tools for their identification, analysis, evaluation and identification are developed. With the growing development of society we got to stadium when, luckily, majority of companies – employers even know the meaning of ergonomics or work risks, about risks at their workplaces and establish their evaluation and try to eliminate them. We have many methods and tools of modern ergonomics which enable us to realize analysis and optimization of employee's work to their benefit. Considering experience we can surely claim that we know the main problem of these days. It is requisite to realize ergonomic evaluation perfectly, extensively and mainly quickly. Slowness of some solutions discourages managers and directors and makes effective improving of work conditions impossible. The idea of mobile application developing which works as a screening tool came with demands from big companies that have dozens of workplaces and cannot identify work risks by themselves. Ceit ERgonomics Analysis Application, which is described in article, is output of our own research and development. It is a mobile application developed in CEIT Company in collaboration with the University of Žilina and Slovak ergonomic association. It is a screening evaluation of space conditions and work positions of workers at potentially risky workplaces. It is developed at the base of legislation and technical norms, at our own platform, with the support of virtual and augmented reality. The main goal of evaluation by the CERAA usage is to find out if the workplace is risky from the ergonomic view. It is an innovative way of applied augmented reality tools during the ergonomic evaluation of chosen workplaces. Nowadays, the new submodules are being developed. They will identify risks at administrative workplaces, submodule which will evaluate working with loads and other that will evaluate repetitive operations. CERAA is used in several industrial companies in Slovakia and Czech Republic from the second half of 2016.
