ErgonomicsEvaluationLab

Short description

The Ergonomics Evaluation Lab (EEL) is a specialized research facility at the interface of human factors and robotics. It serves as a central platform for the objective recording and analysis of human responses in interaction with advanced technical systems. Equipped with state-of-the-art sensor and simulation systems, the EEL enables the detailed investigation of physical and cognitive loads in scenarios involving human-robot collaboration, teleoperation, and virtual workplace design.

Initial situation

The development of intelligent robotics systems (smart robotics) is increasingly shifting from isolated industrial applications to direct collaboration scenarios with humans (shared workspaces). To ensure that these new technologies are safe, efficient, and conducive to healthy working conditions, subjective user assessments are often insufficient. Standardized environments that allow for the empirical validation of the complex human-machine dynamics under controlled conditions and with a high level of ground truth are frequently lacking.

Objective

The goal of the EEL is to provide a flexible and highly precise testing environment that allows for the objective recording of human performance and strain in diverse scenarios. By integrating multimodal data streams, the laboratory aims to support research at the human-technology interface. Specifically, the lab serves to:

Facilitate the investigation of interaction patterns between humans and technical assistance systems (e.g., exoskeletons, cobots).

Combine various sensor data (movement, gaze behavior, haptics) to gain a better understanding of human ergonomics in digital environments.

Provide a platform on which new concepts of teleoperation and human-machine interfaces can be explored and further developed.

Equipment and methods (procedure)

The EEL employs a multi-sensor approach to fully digitally map human interaction. The methodological foundation is the synchronization of the following systems:

Kinematics & Biomechanics: Use of a Vicon motion tracking system for precise optical capture and an Xsens Awinda system for location-independent, inertial tracking.

Fine Motor Skills & Haptics: Use of Manus Metagloves for detailed analysis of finger movements and gripping forces (particularly relevant for teleoperation).

Visual Attention & Cognition: Capture of eye movements and cognitive load using Tobii Pro Spark eye trackers.

Simulation & Immersion: Use of HTC Vive XR systems to create immersive test environments (virtual & mixed reality) to simulate scenarios without physical risk.
