SCD4VPR: Multi-modal Scene Change Detection for Long-term Visual Place Recognition Database Update
Diwei Sheng, Vijayraj Gohil, Satyam Gaba +5
Long-term autonomy in mobile robotics requires maps that remain accurate as environments change over time. Visual Place Recognition (VPR), a core localization capability, degrades…
Evaluating OCR Performance for Assistive Technology: Effects of Walking Speed, Camera Placement, and Camera Type
Junchi Feng, Nikhil Ballem, Mahya Beheshti +5
Optical character recognition (OCR), a process that converts printed or handwritten text into machine-readable form, is widely used in assistive technology for people with blindnes…
Exploring the Use of VLMs for Navigation Assistance for People with Blindness and Low Vision
Yu Li, Yuchen Zheng, Giles Hamilton-Fletcher +6
This paper investigates the potential of vision-language models (VLMs) to assist people with blindness and low vision (pBLV) in navigation tasks. We evaluate state-of-the-art close…
A Multimodal Assistive System for Product Localization and Retrieval for People who are Blind or have Low Vision
Ligao Ruan, Giles Hamilton-Fletcher, Mahya Beheshti +3
Shopping is a routine activity for sighted individuals, yet for people who are blind or have low vision (pBLV), locating and retrieving products in physical environments remains a…
Robust Computer-Vision based Construction Site Detection for Assistive-Technology Applications
Junchi Feng, Giles Hamilton-Fletcher, Nikhil Ballem +5
Purpose: Navigating urban environments poses significant challenges for individuals who are blind or have low vision, especially in areas affected by construction. Construction zon…
Does Embodiment Matter to Biomechanics and Function? A Comparative Analysis of Head-Mounted and Hand-Held Assistive Devices for Individuals with Blindness and Low Vision
Gaurav Seth, Hoa Pham, Giles Hamilton-Fletcher +2
Visual assistive technologies, such as Microsoft Seeing AI, can improve access to environmental information for persons with blindness or low vision (pBLV). Yet, the physical and f…
