In cooperation with Dresden University of Technology, Chair of Labor Sciences, ergonomic tools are developed, emphasizing particularly the integration of normative ergonomic requirements.
Ergotyping® includes methods and digital tools to be used for the analysis, assessment and design of the ergonomic aspects of Digital Prototyping

Undershooting of viewing distance (Limit to adjust focus) - max. accommodation, non-tiring accommodation (25, 40, 50 years old)
Exceeding the admissible vertical/horizontal viewing angle
Viewing angle for High/Medium/Low visual quality requirements
Relative visual acuity
Fusional vergence
Fields of view (sharp, color, monochromatic, optimal)
Visual display of icons, alphanumeric elements and analogue scales with intervals of one, two, or five
Viewing distance from the display area, optimal and approved parameters.
Assessment of Visibility

(normative) evaluation procedure, based on the maximum static action forces collected in the national force standards (DIN 33411-4 DIN 33411-5 )
Force atlas for assembly operations
(Montagespezifischer Kraftatlas)
– as-is-analysis
– planning analysis (general planning or detailed planning)
The health risk the specific force application carries is evaluated according to a three-zone model ("traffic light" scheme)
Evaluation methods:
Actual state analysis ISO 11228-2:2010
Planning analysis DIN EN 1005-2
Body forces evaluation
evaluation procedure: detailed planning Force atlas for assembly operations
evaluation procedure: general planning DIN 33411-4 DIN 33411-5

In the course of the Phiamo Electro Car Project Workflow we tested the working relationship of a package designer, a car bodywork design engineer and an ergonomist in a cloud computing environment.
Participants of the Cruzbike Cuervo Project were a bike producer company from the United States, a designer from Australia and a German ergonomist.
Online workflow, example
