"Towards the Design of Wearable Assistive Technologies to Address the Privacy and Security Concerns of People with Visual Impairments"
Golisano College presents Tousif Ahmed, faculty candidate in HCI/Accessibility.Abstract: Visual awareness of people in the vicinity is key to managing one’s privacy and security in everyday environments and is particularly challenging for people with visual impairments. A sighted person can modulate their activity in a public situation based on the presence of people in the vicinity. For example, a sighted person might not talk about a sensitive topic near other people who can overhear the conversation or may not withdraw money from an ATM if suspicious people are present nearby. But these everyday situations present a challenge for people with visual impairments, who are less able to readily monitor the social conditions around them. As a result, people with visual impairments face risks that may compromise their privacy or security. In this talk, I will first present the physical privacy, security, and safety risks of people with visual impairments that may arise due to the limited ability to judge their surrounding environments and how people are managing the risks. Since existing coping strategies can still put a person in danger, in this talk I will also discuss the potential of a camera-based system that may help people with visual impairments to have a better awareness of their surroundings. A camera-based solution, however, can be invasive to the sighted bystanders because it may involve collecting information about the bystanders such as their presence and location. I will also present the views, perceptions, and concerns of sighted bystanders regarding their information sharing preferences with assistive camera solutions. Bio: Tousif Ahmed is a PhD candidate in the School of Informatics, Computing, and Engineering (SICE) at Indiana University Bloomington, advised by Dr. Apu Kapadia. He received his B.S. in Computer Science and Engineering from Bangladesh University and Engineering Technology (BUET) in 2012. His research interests span various topics in usable security and privacy, with a focus on the privacy and security of people with visual impairments.
