This study introduces an active joystick with force feedback to help powered wheelchair users navigate tight spaces. The new device aims to improve control and environmental awareness for enhanced mobility.

Area of Science:

  • Robotics
  • Assistive Technology
  • Human-Computer Interaction

Background:

  • Powered wheelchair users often struggle with maneuvering in confined environments.
  • Challenges include precise control via joysticks and lack of environmental sensory feedback.
  • Existing assistive technologies may not fully address these navigation difficulties.

Purpose of the Study:

  • To develop and implement an active joystick with force feedback for powered wheelchairs.
  • To design control algorithms that enhance user navigation in confined spaces.
  • To provide sensory feedback to powered wheelchair users regarding environmental obstacles.

Main Methods:

  • Development of an active joystick prototype incorporating force feedback capabilities.
  • Implementation of two distinct force feedback schemes to assist wheelchair users.
