Help Supporters: Exploring the Design Space of Assistive Technologies to Support Face-to-Face Help Between Blind and Sighted Strangers
Proceedings of the CHI Conference on Human Factors in Computing Systems(2024)
摘要
Blind and low-vision (BLV) people face many challenges when venturing into
public environments, often wishing it were easier to get help from people
nearby. Ironically, while many sighted individuals are willing to help, such
interactions are infrequent. Asking for help is socially awkward for BLV
people, and sighted people lack experience in helping BLV people. Through a
mixed-ability research-through-design process, we explore four diverse
approaches toward how assistive technology can serve as help supporters that
collaborate with both BLV and sighted parties throughout the help process.
These approaches span two phases: the connection phase (finding someone to
help) and the collaboration phase (facilitating help after finding someone).
Our findings from a 20-participant mixed-ability study reveal how help
supporters can best facilitate connection, which types of information they
should present during both phases, and more. We discuss design implications for
future approaches to support face-to-face help.
