Virtual Technician: A multi-modal interface facilitating therapists’ adoption of rehab robots

MWMax-Ole Bastian von WaldowRRRobert RienerMSMichael Sommerhalder

Key Points

  • The aim is to enhance therapist interaction with rehabilitation robots through an intuitive multi-modal interface.
  • Developed a multi-modal interface called Virtual Technician.
  • Utilized a Large Language Model with approximately 4 billion parameters.
  • Tested the interface's ability to process abstract natural language commands.
  • The Virtual Technician effectively mapped therapeutic intentions to robot parameter adjustments.
  • The Large Language Model successfully handled natural language commands.
  • The interface improved the usability of rehabilitation robots for therapists.

Abstract

Rehabilitation robots support physiotherapy but therapeutic intention can be difficult to express as robotic parameter adjustments. A multi-modal interface, the Virtual Technician, is conceptualized to provide an intuitive mapping of intention to robot parameters. A demonstrator of the Virtual Technician based on a Large Language Model (LLM) showed that LLMs of ?4 billion parameters can cope with abstract natural language commands to adjust typical parameters of rehabilitation robots.
