  @article{hu24hoimotion, abstract = {We present HOIMotion – a novel approach for human motion forecasting during human-object interactions that integrates information about past body poses and egocentric 3D object bounding boxes. Human motion forecasting is important in many augmented reality applications but most existing methods have only used past body poses to predict future motion. HOIMotion first uses an encoder-residual graph convolutional network (GCN) and multi-layer perceptrons to extract features from body poses and egocentric 3D object bounding boxes, respectively. Our method then fuses pose and object features into a novel pose-object graph and uses a residual-decoder GCN to forecast future body motion. We extensively evaluate our method on the Aria digital twin (ADT) and MoGaze datasets and show that HOIMotion consistently outperforms state-of-the-art methods by a large margin of up to 8.7% on ADT and 7.2% on MoGaze in terms of mean per joint position error. Complementing these evaluations, we report a human study (N=20) that shows that the improvements achieved by our method result in forecasted poses being perceived as both more precise and more realistic than those of existing methods. Taken together, these results reveal the significant information content available in egocentric 3D object bounding boxes for human motion forecasting and the effectiveness of our method in exploiting this information.}, archiveprefix = {arXiv}, author = {Hu, Zhiming and Yin, Zheming and Haeufle, Daniel and Schmitt, Syn and Bulling, Andreas}, eprint = {2407.02633}, journal = {IEEE Transactions on Visualization and Computer Graphics (TVCG)}, note = {spotlight}, pages = {1--11}, primaryclass = {cs.CV}, title = {HOIMotion: Forecasting Human Motion During Human-Object Interactions Using Egocentric 3D Object Bounding Boxes}, url = {https://arxiv.org/abs/2407.02633}, year = 2024 }

  @article{10.1088/1748-3190/ad3602, abstract = {Recognizing humans' unmatched robustness, adaptability, and learning abilities across anthropomorphic movements compared to robots, we find inspiration in the simultaneous development of both morphology and cognition observed in humans. We utilize optimal control principles to train a muscle-actuated human model for both balance and squat jump tasks in simulation. Morphological development is introduced through abrupt transitions from a 4-year-old to a 12-year-old morphology, ultimately shifting to an adult morphology. We create two versions of the 4-year-old and 12-year-old models— one emulating human ontogenetic development and another uniformly scaling segment lengths and related parameters. Our results show that both morphological development strategies outperform the non-development path, showcasing enhanced robustness to perturbations in the balance task and increased jump height in the squat jump task. Our findings challenge existing research as they reveal that starting with initial robot designs that do not inherently facilitate learning and incorporating abrupt changes in their morphology can still lead to improved results, provided these morphological adaptations draw inspiration from biological principles.}, author = {Badie, Nadine and Schmitt, Syn}, doi = {10.1088/1748-3190/ad3602}, journal = {Bioinspiration & Biomimetics}, title = {Enhancing stance robustness and jump height in bipedal muscle-actuated systems: A bioinspired morphological development approach}, url = {http://iopscience.iop.org/article/10.1088/1748-3190/ad3602}, year = 2024 }

  @article{Waldhof.2022, abstract = {Exoskeletons are powerful tools for aiding humans with pathological conditions, in dangerous environments or in manually exhausting tasks. Typically, they are designed for specific maximum scenarios without taking into account the diversity of tasks and the individuality of the user. To address this discrepancy, a framework was developed for personalizing an exoskeleton by scaling the components, especially the electrical machine, based on different simulated human muscle forces. The main idea was to scale a numerical arm model based on body mass and height to predict different movements representing both manual labor and daily activities. The predicted torques necessary to produce these movements were then used to generate a load/performance cycle for the power unit design. Considering these torques, main operation points of this load cycle were defined and a reference power unit was scaled and optimized. Therefore, a scalability model for an electrical machine is introduced. This individual adaptation and scaling of the power unit for different users leads to a better performance and a lighter design.}, author = {Waldhof, Marcel and Wochner, Isabell and Stollenmaier, Katrin and Parspour, Nejila and Schmitt, Syn}, doi = {10.3390/robotics11050107}, file = {robotics-11-00107:S\:\\Mitarbeiter\\01_Bibliothek\\01_Literatur\\Citavi Attachments\\robotics-11-00107.pdf:pdf}, journal = {Robotics}, number = 5, pages = 107, title = {Design and Scaling of Exoskeleton Power Units Considering Load Cycles of Humans}, url = {https://doi.org/10.3390/robotics11050107}, volume = 11, year = 2022 }

  @article{haeufle2020morphological, abstract = {Voluntary movements, like point-to-point or oscillatory human arm movements, are generated by the interaction of several structures. High-level neuronal circuits in the brain are responsible for planning and initiating a movement. Spinal circuits incorporate proprioceptive feedback to compensate for deviations from the desired movement. Muscle biochemistry and contraction dynamics generate movement driving forces and provide an immediate physical response to external forces, like a low-level decentralized controller. A simple central neuronal command like "initiate a movement" then recruits all these biological structures and processes leading to complex behavior, e.g., generate a stable oscillatory movement in resonance with an external spring-mass system. It has been discussed that the spinal feedback circuits, the biochemical processes, and the biomechanical muscle dynamics contribute to the movement generation, and, thus, take over some parts of the movement generation and stabilization which would otherwise have to be performed by the high-level controller. This contribution is termed morphological computation and can be quantified with information entropy-based approaches. However, it is unknown whether morphological computation actually differs between these different hierarchical levels of the control system. To investigate this, we simulated point-to-point and oscillatory human arm movements with a neuro-musculoskeletal model. We then quantify morphological computation on the different hierarchy levels. The results show that morphological computation is highest for the most central (highest) level of the modeled control hierarchy, where the movement initiation and timing are encoded. Furthermore, they show that the lowest neuronal control layer, the muscle stimulation input, exploits the morphological computation of the biochemical and biophysical muscle characteristics to generate smooth dynamic movements. This study provides evidence that the system's design in the mechanical as well as in the neurological structure can take over important contributions to control, which would otherwise need to be performed by the higher control levels.}, author = {Haeufle, Daniel F.

  @article{Moerl2020a, abstract = {The load distribution among lumbar spinal structures---still an unanswered question---has been in the focus of this hybrid experimental and simulation study. First, the overall passive resistive torque-angle characteristics of healthy subjects' lumbar spines during flexion--extension cycles in the sagittal plane were determined experimentally by use of a custom-made trunk-bending machine. Second, a forward dynamic computer model of the human body that incorporates a detailed lumbar spine was used to (1) simulate the human--machine interaction in accordance with the experiments and (2) validate the modeled properties of the load-bearing structures. Third, the computer model was used to predict the load distribution in the experimental situation among the implemented lumbar spine structures: muscle--tendon units, ligaments, intervertebral discs, and facet joints. Nine female and 10 male volunteers were investigated. Lumbar kinematics were measured with a marker-based infrared device. The lumbar flexion resistance was measured by the trunk-bending machine through strain gauges on the axes of the machine's torque motors. Any lumbar muscle activity was excluded by simultaneous sEMG monitoring. A mathematical model was used to describe the nonlinear flexion characteristics. The subsequent extension branch of a flexion--extension torque--angle characteristic could be significantly distinguished from its flexion branch by the zero-torque lordosis angle shifted to lower values. A side finding was that the model values of ligament and passive muscle stiffnesses, extracted from well-established literature sources, had to be distinctly reduced in order to approach our measured overall lumbar stiffness values. Even after such parameter adjustment, the computer model still predicts too stiff lumbar spines in most cases in comparison with experimental data. A review of literature data reveals a deficient documentation of anatomical and mechanical parameters of spinal ligaments. For instance, rest lengths of ligaments---a very sensitive parameter for simulations---and cross-sectional areas turned out to be documented at best incompletely. Yet by now, our model well reproduces the literature data of measured pressure values within the lumbar disc at level L4/5. Stretch of the lumbar dorsal (passive) muscle and ligament structures as an inescapable response to flexion can fully explain the pressure values in the lumbar disc. Any further external forces like gravity, or any muscle activities, further increase the compressive load on a vertebral disc. The impact of daily or sportive movements on the loads of the spinal structures other than the disc cannot be predicted ad hoc, because, for example, the load distribution itself crucially determines the structures' current lever arms. In summary, compressive loads on the vertebral discs are not the major determinants, and very likely also not the key indicators, of the load scenario in the lumbar spine. All other structures should be considered at least equally relevant in the future. Likewise, load indicators other than disc compression are advisable to turn attention to. Further, lumbar flexion is a self-contained factor of lumbar load. It may be worthwhile, to take more consciously care of trunk flexion during daily activities, for instance, regarding long-term effects like lasting repetitive flexions or sedentary postures.}, author = {M{\"o}rl, Falk and G{\"u}nther, Michael and Riede, Julia M. and Hammer, Maria and Schmitt, Syn}, day = 01, doi = {10.1007/s10237-020-01322-7}, issn = {1617-7940}, journal = {Biomechanics and Modeling in Mechanobiology}, month = {12}, number = 6, pages = {2015-2047}, title = {{Loads distributed in vivo among vertebrae, muscles, spinal ligaments, and intervertebral discs in a passively flexed lumbar spine}}, url = {https://doi.org/10.1007/s10237-020-01322-7}, volume = 19, year = 2020 }

  @article{haeufle2020muscles, abstract = {It is hypothesized that the nonlinear muscle characteristic of biomechanical systems simplify control in the sense that the information the nervous system has to process is reduced through off-loading computation to the morphological structure. It has been proposed to quantify the required information with an information-entropy based approach, which evaluates the minimally required information to control a desired movement, i.e., control effort. The key idea is to compare the same movement but generated by different actuators, e.g., muscles and torque actuators, and determine which of the two morphologies requires less information to generate the same movement. In this work, for the first time, we apply this measure to numerical simulations of more complex human movements: point-to-point arm movements and walking. These models consider up to 24 control signals rendering the brute force approach of the previous implementation to search for the minimally required information futile. We therefore propose a novel algorithm based on the pattern search approach specifically designed to solve this constraint optimization problem. We apply this algorithm to numerical models, which include Hill-type muscle-tendon actuation as well as ideal torque sources acting directly on the joints. The controller for the point-to-point movements was obtained by deep reinforcement learning for muscle and torque actuators. Walking was controlled by proprioceptive neural feedback in the muscular system and a PD controller in the torque model. Results show that the neuromuscular models consistently require less information to successfully generate the movement than the torque-driven counterparts.

  @article{wochner2020optimality, abstract = {Human arm movements are highly stereotypical under a large variety of experimental conditions. This is striking due to the high redundancy of the human musculoskeletal system, which in principle allows many possible trajectories toward a goal. Many researchers hypothesize that through evolution, learning, and adaption, the human system has developed optimal control strategies to select between these possibilities. Various optimality principles were proposed in the literature that reproduce human-like trajectories in certain conditions. However, these studies often focus on a single cost function and use simple torque-driven models of motion generation, which are not consistent with human muscle-actuated motion. The underlying structure of our human system, with the use of muscle dynamics in interaction with the control principles, might have a significant influence on what optimality principles best model human motion. To investigate this hypothesis, we consider a point-to-manifold reaching task that leaves the target underdetermined. Given hypothesized motion objectives, the control input is generated using Bayesian optimization, which is a machine learning based method that trades-off exploitation and exploration. Using numerical simulations with Hill-type muscles, we show that a combination of optimality principles best predicts human point-to-manifold reaching when accounting for the muscle dynamics.}, author = {Wochner, Isabell and Driess, Danny and Zimmermann, Heiko and Haeufle, Daniel FB and Toussaint, Marc and Schmitt, Syn}, doi = {https://doi.org/10.3389/fncom.2020.00038}, journal = {Frontiers in Computational Neuroscience}, pages = 38, publisher = {Frontiers}, title = {Optimality principles in human point-to-manifold reaching accounting for muscle dynamics}, url = {https://www.frontiersin.org/articles/10.3389/fncom.2020.00038/full}, volume = 14, year = 2020 }

  @article{Roehrle2017a, abstract = {By following the common definition of forward-dynamics simulations, i.e. predicting movement based on (neural) muscle activity, this work describes, for the first time, a forward-dynamics simulation framework of a musculoskeletal system, in which all components are represented as continuous, three-dimensional, volumetric objects. Within this framework, the mechanical behaviour of the entire muscle--tendon complex is modelled as a nonlinear hyperelastic material undergoing finite deformations. The feasibility and the full potential of the proposed forward-dynamics simulation framework is demonstrated on a two-muscle, three-dimensional, continuum-mechanical model of the upper limb. The musculoskeletal model consists of three bones, i.e. humerus, ulna, and radius, an one-degree-of-freedom elbow joint, and an antagonistic muscle pair, i.e. the biceps and triceps brachii, and takes into consideration the contact between the skeletal muscles and the humerus. Numerical studies have shown that the proposed upper limb model is capable of predicting realistic moment arms and muscle forces for the entire range of activation and motion. Within the limitations of the model, the presented simulations provide, for the first time, insights into existing contact forces and their influence on the muscle fibre stretch. Based on the presented simulations, the overall change in fibre stretch is typically less than 3{\%}, despite the fact that the contact forces reach up to 71{\%} of the exerted muscle force. Movement-predicting simulations are achieved by minimising a nonlinear moment equilibrium equation. Based on the forward-dynamics simulation approach, an iterative solution procedures for position-driven (inverse dynamics) and force-driven scenarios have been proposed accordingly. Applying these methodologies to time-dependent scenarios demonstrates that the proposed methods can be linked to state-of-the-art control algorithms predicting time-dependent muscle activation levels based on principles of forward dynamics.}, author = {R{\"o}hrle, O. and Sprenger, M. and Schmitt, S.}, day = 01, doi = {10.1007/s10237-016-0850-x}, issn = {1617-7940}, journal = {Biomechanics and Modeling in Mechanobiology}, month = {06}, number = 3, pages = {743--762}, title = {A two-muscle, continuum-mechanical forward simulation of the upper limb}, url = {https://doi.org/10.1007/s10237-016-0850-x}, volume = 16, year = 2017 }

  @article{David2014a, abstract = {This study aimed at finding simple algorithms to identify three different movements registered by accelerometer and to detect differences in the acceleration signals of people with and without visual impairments. The Tactile Acoustical Navigation and Information Assistant (TANIA) is construed to provide persons suffering from visual impairments support for an independent navigation indoors and outdoors. Attaining this goal, TANIA uses vertical acceleration signal extrema to assess its user's walking distance. This study investigated first the sit-to-stand movement, stumbling and walking up- and down stairs of 25 subjects with visual impairments using TANIA sensor system. The objective was to improve the user's movement detection using sensors to get valid and reliable data. In a second step of the study it was investigated if there is a difference between the above-mentioned movements in people with or without visual impairments (n=10). The acceleration signals of the subjects were compared. Three simple algorithms were found, which are able to separate the movement signals based on accelerometers of the respective daily movements. The second step analysis revealed a detectable difference in the second phase of stumbling (p=.034), where the subjects had to get back into walking forward. No differences in the other acceleration signals were found.}, author = {David, Sina and Schmitt, Syn and Utz, Julianne and Hub, Andreas and Schlicht, Wolfgang}, doi = {https://doi.org/10.1016/j.ridd.2014.04.032}, issn = {0891-4222}, journal = {Research in Developmental Disabilities}, number = 9, pages = {2026 - 2034}, title = {Navigation within buildings: Novel movement detection algorithms supporting people with visual impairments}, url = {http://www.sciencedirect.com/science/article/pii/S0891422214002005}, volume = 35, year = 2014 }

  @article{schmitt2009novel, abstract = {The etiology of ankle sprain injury is still under debate. Therefore, diagnoses of ankle inversion experiments play an important role. Recent studies stress the importance of exact time measurements due to the short inversion period of around 70ms. This paper presents a novel approach using the vertical ground reaction force (vGRF) to determine the short-time intervals in ankle sprain experiments, which are present in the form of short periods from the beginning of the movement to its end and short latencies to following signals, e.g. EMG onset of peroneal muscles. We compare our method to electrogoniometry at the ankle which is considered as the gold standard. During the inversion movement the kinematic action at the ankle can be measured with electrogoniometry, whereas the vGRF quantifies the vertical dynamic reaction of the tested subject entirely. We observe a difference of DeltaT(f,0-->g,0)=10+/-0.5ms between the first observable vGRF response and the first observable electrogoniometer response following platform release. The end of the ankle inversion measured with electrogoniometry is DeltaT(f,1-->g,1)=3+/-0.5ms later than the maximal vGRF peak. The potential supplementary (mechanical) information of this novel approach compared to electrogoniometry and its ease of use, may be not only interesting for researchers when studying ankle sprain simulations but also for clinicians when testing functional ankle stability.}, address = {Institut fur Sport- und Bewegungswissenschaft, Universitat Stuttgart, Allmandring 28, D-70569 Stuttgart, Germany.}, author = {Schmitt, S and Melnyk, M and Alt, W and Gollhofer, A}, bdsk-url-1 = {http://dx.doi.org/10.1016/j.jbiomech.2009.08.015}, crdt = {2009/09/22 06:00}, da = {20090921}, date-added = {2009-11-14 16:02:17 +0100}, date-modified = {2010-01-11 09:42:14 +0100}, dep = {20090917}, doi = {10.1016/j.jbiomech.2009.08.015}, edat = {2009/09/22 06:00}, issn = {1873-2380 (Electronic)}, jid = {0157375}, journal = {{Journal of Biomechanics}}, jt = {Journal of biomechanics}, language = {ENG}, mhda = {2009/09/22 06:00}, own = {NLM}, pages = {2823-2825}, phst = {2008/04/29 {$[$}received{$]$}; 2009/06/30 {$[$}revised{$]$}; 2009/08/11 {$[$}accepted{$]$}}, pii = {S0021-9290(09)00455-2}, pmid = {19766223}, pst = {aheadofprint}, pt = {JOURNAL ARTICLE}, so = {J Biomech. 2009 Sep 17.}, stat = {Publisher}, title = {Novel approach for a precise determination of short-time intervals in ankle sprain experiments.}, url = {http://dx.doi.org/10.1016/j.jbiomech.2009.08.015}, volume = 42, year = 2010 }

The purpose of the study was to investigate the effects of 4-weeks WBV training on reflex activity of the long peroneal and tibialis anterior muscles and on the duration of ankle inversion movement in response to an unexpected combined 24 degrees inversion 15 degrees plantar flexion ankle joint motion. Twenty-six healthy subjects were divided into an intervention group (n=16) and a control group (n=10). The intervention group trained thrice weekly for 3 min on a unidirectional oscillating vibration platform (30 Hz, 4 mm amplitude). Pre and post intervention reflex activity were measured and the duration of ankle joint movement was calculated by vertical ground reaction forces. After four weeks of WBV training no significant changes were found in latencies and reflex activity in both muscles in response to ankle sprain simulation. Similar results were observed for the time of ankle inversion motion.
