Safe and Efficient Navigation Considering Texting Pedestrians via Attention-Aware Cost-Map Tuning

Smartphone-distracted pedestrians deviate from social norms unpredictably and cannot be relied upon to yield to approaching robots — a safety challenge that existing navigation methods are poorly equipped to handle, since they treat all pedestrians uniformly regardless of attention state. We propose an attention-aware...

An AI-Interactive Shopping Navigation Assistance System for Visually Impaired People via Passive Kinesthetic Guidance

Visually impaired individuals face two main challenges when shopping independently: accessing product information and moving safely. Natural-language interfaces can solve the first problem by allowing users to easily ask about the desired item. However, ensuring safe physical mobility in a complex store environment rem...

Close-Proximity Vision-Guided Control and Performance Evaluation of a Mobile Robot for Sit-to-Stand Assistance

A safe sit-to-stand (STS) transfer is an essential daily movement, but it can be difficult for older adults with reduced strength, balance, or coordination. Cost-effective STS assistance is therefore important for supporting independence. This paper presents a close-range, single RGB-D-camera solution for estimating pe...
