Summary

Recommendation ITU-T F.922 establishes requirements for an information service system for visually impaired persons (ISS-VIPs), based on the mobile Internet, which connects visually impaired persons (VIPs) and volunteers. With the assistance of volunteers, the system enables VIPs to solve problems not yet handled by automatic assistive technology. The ISS-VIPs is constructed in client/server mode, enabling VIPs and volunteers to access it through their client software and to use its services or to provide its services to another person. The ISS-VIPs provides three kinds of service: image recognition; video assistance; and trip companion. The ISS-VIPs also supports the use of other software tools for assisting VIPs, so as to save valuable volunteer resources for service provision in person. While provision of services to VIP is the top priority, the ISS-VIPs can also be used by non-VIP with special service requirements.
