BMBF Project Easy Cohmo
Ergonomics Assistance Systems for Contactless Human-Machine-Operation
Period: 01. January 2017 – 31. December 2019
This project is founded by BMBF under grant 03ZZ0443E
The collaborative project EASY-COHMO of the 3DSensation consortium targets the exploration and development of operational concepts for human-machine interaction and human-machine cooperation, seamlessly integrated in different working contexts. As a part of this general objective, this subproject addresses the object- and room-stable augmentation of the environment or working space. A context sensitive spatial presentation of additional information and visualizations of three-dimensional data is supporting the user and allows the machine to communicate its status. The subproject on the one hand includes analysis components to capture the augmented environment and on the other hand the processing and presentation of the displayed content. This includes a perspective distortion of the content to guaranty a correct displaying independent of the augmented area, which can potentially be the complete working space of the user. To show information at the correct position in space, head mounted displays and projector-based systems, following the concept of spatial augmented reality, are used. As the application domain of the different industry partners differs very much in terms of the working environment and the displayed data (e.g. workflow information in production halls or atlas data of a patient) all algorithms are designed as generic as possible. This allows a custom configuration and adaption matching the individual conditions.
Images
The interaction in an collaborative human-roboter inspection task is facilitated by projecor based augmented reality. Left: Touchless interaction with an projective interface. Right: Gesture based interaction with the workpiece.
The developed software aligns virtual representations of objects or interfaces with real-world geometry and renders a predistored image on a projector. The projection matches exactly with the real objects and manipulates their appearance.
