Improving Walking Path Generation Through Biped Constraint in Indoor Navigation System for Visually Impaired...

Area of Science:

• Robotics
• Human-Computer Interaction
• Assistive Technology

Background:

• Visually impaired individuals face significant challenges with indoor navigation.
• Existing assistive devices often lack natural and efficient navigation capabilities.

Purpose of the Study:

• To develop an advanced walking path generation method for the Smart Cane, a Robotic Navigation Assistance Device (RNA).
• To ensure generated paths adhere to human motion constraints for a natural and efficient navigation experience.
• To improve indoor navigation for visually impaired individuals.

Main Methods:

• Utilized Linear Inverse Pendulum Model (LIPM) and Linear Foot Placement Controller (LFPC) motion primitives.
• Integrated an autonomous navigation framework within the Smart Cane.
• Generated walking paths specifically tailored for the constraints of visually impaired users.

Main Results:

• The proposed method successfully generated walking paths conforming to human motion constraints.
• Comparative experiments validated the effectiveness of the path generation technique.
• The Smart Cane demonstrated safe and effective guidance in indoor environments.

Conclusions:

• The developed walking path generation method is a promising solution for enhancing indoor navigation for the visually impaired.
• The Smart Cane, utilizing this method, offers improved mobility and independence.
• Adherence to human motion constraints is crucial for natural and efficient assistive navigation.
