Outline

This paper presents a multimodal guidance simulator that integrates visual, auditory, and tactile feedback to address the challenges faced by blind and low vision (BLV) operators in teleoperating mobile robots in industrial warehouse environments. The simulator reproduces a high-fidelity warehouse environment and generates real-time obstacle avoidance paths through navigation meshes and replanning functions. It supports safe and efficient teleoperation by providing visual paths, directional voice cues, and proximity-based tactile feedback for low vision users. It is designed to be compatible with commercial hardware, allowing rapid application to real robots.

Takeaways, Limitations

•
Takeaways:
◦
Contribute to the development of accessible remote operation technologies for the visually impaired and those with low vision.
◦
We propose an improved user experience through a multi-modal guidance system.
◦
Provides a real-time simulator that increases the possibility of practical robot applications.
◦
Laying the foundation for inclusive technology adoption in industrial settings.
•
Limitations:
◦
Currently, this is a simulator-based study and verification in an actual industrial environment is required.
◦
There is a lack of user testing for different types of visual impairments and levels of low vision.
◦
An analysis of the accuracy of the simulator and the difference with the real environment is required.
◦
Scalability studies for different types of robots and tasks are needed.
