This paper presents our preliminary study on enabling individuals who are legally blind to safely operate mobile robots and vehicles. To achieve this, we developed a teleoperation with accessibility at its core. The system incorporates features that enhance usability and situational awareness, including assistive control based on artificial potential fields to prevent collisions and ensure smooth navigation. It also provides multimodal feedback through (a) haptic vibrations on the gamepad controller, which convey the proximity of nearby objects detected by the robot's laser sensor, and (b) color-coded overlays that differentiate paths, obstacles, and people through semantic segmentation performed by a deep neural network on the robot’s camera feed. To evaluate its effectiveness, we partnered with the Austin Lighthouse to conduct experiments in which legally blind participants used the system to successfully guide the robot through a testing area with obstacles.more » « lessFree, publicly-accessible full text available August 20, 2026
