Human-in-the-Loop Optimization of Hip Exoskeleton Assistance During Stair Climbing. [PDF]
IEEE Trans Biomed EngThis study applies human-in-the-loop optimization to identify optimal hip exoskeleton assistance patterns for stair climbing.Ten participants underwent optimization to individualize hip flexion and extension assistance, followed by a validation comparing optimized assistance (OPT) to biological hip moment-based assistance (BIO), no assistance (No ...

Human-in-the-Loop Optimization for Deep Stimulus Encoding in Visual Prostheses. [PDF]
Adv Neural Inf Process Syst, 2023 Neuroprostheses show potential in restoring lost sensory function and enhancing human capabilities, but the sensations produced by current devices often seem unnatural or distorted. Exact placement of implants and differences in individual perception lead to significant variations in stimulus response, making personalized stimulus optimization a key ...

Human-in-the-Loop Optimization of Shared Autonomy in Assistive Robotics. [PDF]
IEEE Robot Autom Lett, 2017 In this paper, we propose a mathematical framework which formalizes user-driven customization of shared autonomy in assistive robotics as a nonlinear optimization problem. Our insight is to allow the end-user, rather than relying on standard optimization techniques, to perform the optimization procedure, thereby allowing us to leave the exact nature of

Engagement Enhancement Based on Human-in-the-Loop Optimization for Neural Rehabilitation. [PDF]
Front Neurorobot, 2020 Enhancing patients' engagement is of great benefit for neural rehabilitation. However, physiological and neurological differences among individuals can cause divergent responses to the same task, and the responses can further change considerably during training; both of these factors make engagement enhancement a challenge.

Validation of Dynamic Bayesian Optimization for a Non-Stationary Human-in-the-Loop Optimization Problem. [PDF]
IEEE Robot Autom LettAbstract Human-in-the-Loop Optimization (HILO) has demonstrated efficacy in achieving a plethora of assistive or augmentative effects. However, conventional optimizers such as Bayesian optimization (BO) do not account for the non-stationary aspects of the human-robot system, and may thus be limited in the domains of robot-assisted ...

On Human-in-the-Loop Optimization of Human–Robot Interaction
NatureFrom industrial exoskeletons to implantable medical devices, robots that interact closely with people are poised to improve every aspect of our lives. Yet designing these systems is very challenging; humans are incredibly complex and, in many cases, we respond to robotic devices in ways that cannot be modelled or predicted with sufficient accuracy.
