Would be cool if a digital human model designs products. Well, the truth is, Jack helps validating products which are used by humans. For example, if a driver in a car can reach all switches or if the visibility to objects outside of the car is sufficient. The seamless integration between Jack and NX helps product engineers to run this validation directly in the CAD system.
Ulrich Raschke, Director of the Tecnomatix Ergonomics Products talks about how product designers use Jack to validate the product design. He mentions the US Postal Service as an example which used this technology.
