summary

WebAlly is a prototype that lets people with visual impairments transfer task-based visual CAPTCHAs to a remote helper via an interactive screenshot limited remote control that crops and mirrors only the CAPTCHA area. The team runs a role-play study with 18 participants in 10 pairs across four conditions (friend vs stranger and paid vs volunteer), finds PVIs accept it as a last-resort option, it reduces some privacy/security risks, allies worry about open links, and the system proves feasible.
