A Human-centered Process
To develop the planned assistance units, at first, the requirements of future users in production contexts had to be identified. Starting point was the overall goal of detecting and identifying opportunities and challenges for future assistance systems from a user’s perspective. Thus, in order to identify the main assistance needs from a workers’ perspective, an extensive context-oriented requirements analysis was conducted, involving various stakeholders (future users and decision makers as well). The study took place between August 2017 and January 2018 at nine industrial partners’ facilities
Specific Goals of the Requirements Analysis:
- Understand the industrial partners’ application contexts
- Identification of relevant user experience factors
- Identification of assistance needs
The results of this study are available since March 2018 and provide the basis for the conception and further implementation of the modular assistance units.
Based on the results of the requirements analysis, the following assistance units – which will be implemented in the project – were defined together with the implementation and industrial partners:

Interaction Design for Assistance Units
Subsequently, based on the results of the requirements analysis, a series of design workshops were held to develop conceptual designs for these seven assistance units. The conceptual designs illustrate the interaction process between assistance units and users from a user-centered perspective and reflect the identified assistance needs and requirements. These conceptual designs also form the foundation for the further human-centered implementation of the assistance units. Currently, prototypes of the assistance units are implemented and tested on site.
