• ThermalCane: Exploring Thermotactile Directional Cues on Cane-Grip for Non-Visual Navigation

  Arshad Nasser, Kai-Ning Keng, Kening Zhu · 2020 · Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2020)

  This paper presents ThermalCane, a white-cane grip augmented with flexible Peltier thermoelectric modules that provide thermal directional cues for blind and visually impaired (BVI) navigation. While existing haptic navigation aids primarily use vibrotactile feedback (vibration…

• Privacy Considerations of the Visually Impaired with Camera Based Assistive Technologies: Misrepresentation, Impropriety, and Fairness

  Taslima Akter, Tousif Ahmed, Apu Kapadia, Swami Manohar Swaminathan · 2020 · Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2020)

  This paper investigates the privacy concerns of both visually impaired people (PVIs) and sighted bystanders regarding camera-based assistive technologies like smart glasses (Orcam, Aira, eSight) that can identify people and provide demographic and behavioral information about…

• Keep Your Distance: A Playful Haptic Navigation Wearable for Individuals with Deafblindness

  James Gay, Moritz Umfahrer, Arthur Theil, Lea Buchweitz, Eva Lindell, Li Guo, Nils-Krister Persson, Oliver Korn · 2020 · Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2020)

  This demonstration paper presents a haptic wearable vest designed to support independent navigation for people with deafblindness — a dual sensory impairment where the combination of sight and hearing loss makes it difficult for one sense to compensate for the other. Most…

• Tapsonic: One Dimensional Finger Mounted Multimodal Line Chart Reader

  Zeyuan Zhang · 2020 · Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2020)

  This short paper presents Tapsonic, a finger-mounted wearable device that enables people with visual impairments to read line charts through a combination of haptic feedback and voiceover. The key innovation is a dimensionality reduction approach: rather than trying to…

• A Mobile Cloud Collaboration Fall Detection System Based on Ensemble Learning

  Tong Wu, Yang Gu, Yiqiang Chen, Jiwei Wang, Siyu Zhang · 2020 · Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This paper addresses fall detection for older adults, which the WHO identifies as the second leading cause of accidental injury death worldwide. Roughly 28-35% of people over 65 experience falls each year, with the rate increasing to 32-42% for those over 70. The authors propose…

• Chat in the Hat: A Portable Interpreter for Sign Language Users

  Larwan Berke, William Thies, Danielle Bragg · 2020 · Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This paper addresses a fundamental limitation of Video Remote Interpreting (VRI) for Deaf and Hard-of-Hearing (DHH) sign language users: existing smartphone-based VRI requires the DHH person to either hold the phone with one hand (reducing signing to one-handed and causing…

• Tactile Working Memory Capacity of Users Who Are Blind in an Electronic Travel Aid Application with a Vibration Belt

  Jan B. F. van Erp, Katja I. Paul, Tina Mioch · 2020 · ACM Transactions on Accessible Computing

  This paper investigates the tactile working memory capacity of users who are blind when using a vibrotactile belt for electronic travel aid (ETA) applications. ETAs that display obstacle information through vibration belts require users to integrate multiple tactile cues over…
