Seamless integration of assistive systems for natural locomotion of humans
Technical University of Darmstadt & Heidelberg University

Project Area C – Assistance Scenarios and Their Evaluation

In project area C, movement scenarios are cataloged and their identification and the respective interaction with the assisting system is evaluated biomechanically, as well as cognitive and psycho-physiologically. By integrating the user and his physical and cognitive interaction, the experiences and needs of users are considered with the assisting system. PhD students in this project area C take advantage of the new mechatronic options (area A), include them in the assistance scenarios and deliver it to doctoral candidates from area B for iteratively providing a database for modeling sensorimotor movement concepts and movement assistance. Furthermore, the experimental studies receive direct feedback from the work of the doctoral candidates in area D, primarily addressing the individual factors of the user and their body representation for assessing the integration of the assistive system into their body scheme.

PhD Positions

C1 PhD Topic: Assessment of movement and assistance scenarios

Short description

The needs for daily movements and appropriate support through motion assistance systems are very diverse – from quasi-stationary, but load-changing postures, e.g., in the kitchen, hiking in mountainous terrain. We aim to develop a catalog of elementary movements of which these complex movements are composed and their context-specific need for support from the assistance system. Physical limitations, both from biomechanical as well as from the user’s perspective need to be considered.

Research will be performed to review functional handicaps in the context of lower limb prosthetics and orthotics for identifying everyday tasks and transfer situations to be monitored via motion capture, force, EMG measurements and other sensor modalities such as functional materials (ferromagnetic, ferroelectric). Everyday movements will be recorded, categorized and analyzed also in transfer situations for the physically unrestricted as well as their model-based movement decomposition.

The PhD student will perform respective research in movement science, starting from literature review, and cooperate in cohort trials in the motion lab.

Profile and qualification requirements

  • Very good Master's degree in the fields of sports with focus movement science or engineering with focus biomechanics
  • Good programming skills

C2 PhD Topic: Integration of user and expert perspectives in movement limitations along the integration of biomechanical and psychophysiological dimensions

Short description

Assistance systems enable movement support as well as a targeted restriction of movements. In this sub-project, the analysis of measured data will be combined with the individual assessment of users and experts in the various application scenarios to achieve new insights into movement strategies, user perception, and assistance behavior.

Research will be performed in the integration of potential users into the development of systems that are built for the assistance of movements as well as for a targeted limitation of movements. Different movement simulations and their consequences for biomechanical, neuromuscular triggered and individual movement behavior, perception and sensation will be investigated. Respective methods will be developed using state-of-the-art technologies like virtual reality and eye-tracking.

Profile and qualification requirements

  • Excellent Master’s degree in psychology, (cognitive) neuroscience (obtained at the application date) or another natural science
  • Knowledge and interest in experimental psychology and neuroscience; solid background in programming skills and interest in psychophysiological and computer generated methods
  • Knowledge of statistics and familiarization with statistical databases (e.g. SPSS, SAS, R) and complex data analytics will be valued
  • Good English language skills

C3 PhD Topic: Human-in-the-Loop Studies for Assistive Devices

Short description

Human-in-the-loop experiments facilitate a continuous involvement of users in the research and development process of assistive devices. We intend to simulate the assistive system so that users can interactively experience and evaluate during development. Considering locomotion assistance and its cognitive effects, we will enable users to parameterize control algorithms and mechanical properties of the assistive devices online according to their individual preferences.

Profile and qualification requirements

  • Excellent Master’s degree elec./mech. engineering, cognitive/computer science, biomechanics, psychology/neuroscience, or related
  • Knowledge on specific topics and technical skills
  • Experience/interest in human-centric technology
  • Methodical knowledge in either human-robot interaction, mechatronic design/control, or user studies/VR
  • First publications
  • Very good English skills
