36 CFR Part 1194 - Proposed Information and Communication Technology (ICT) Standards and Guidelines NPRM - Preamble

402.1 General (Section-by-Section Analysis)

This section proposes to require ICT with closed functionality to be operable without requiring the user to attach or install assistive technology, with the exception of personal headsets or other audio couplers. This provision is needed because, when ICT has closed functionality, the end user typically does not have the option of installing or attaching assistive technology. Closed functionality can also apply to the platform user interface. This is sometimes referred to as “firmware” because it has a software aspect, but is not alterable by the end-user and the user interface is necessarily tied to the hardware platform. The proposed technical requirements for software (Chapter 5) do not specifically address closed functionality, except for the interoperability of software and assistive technology.

Components of ICT subject to the 255 Guidelines would be excepted from the requirements of this section (see C204.1 Exception) because such telecommunications equipment typically has closed functionality. For example, it is often impossible to attach or install assistive technology, such as a specialized keyboard.

Variable message signs (VMS) frequently are installed in federal buildings and facilities to provide information about ongoing events. Some VMS also convey information relevant to emergencies. VMS with closed functionality would be covered by this section. The Board is currently unaware of any VMS technology that provides audible output. However, there is one voluntary consensus standard addressing accessibility of VMS with respect to the needs of persons with low vision. The most recent edition of the International Code Council (ICC)’s “Accessible and Usable Buildings and Facilities” (ICC A117.1-2009) contains specifications for making high-resolution and low-resolution VMS more accessible to people with low vision. For low-resolution signs, these requirements address signage characters (e.g., case, style, height, width, stroke width, and spacing), as well as other characteristics relating to height above the floor, finish, contrast, protective coverings, brightness, and rate of change. High-resolution VMS need only comply with the provisions for character case (uppercase), protective coverings, brightness, and rate of change since they typically meet or exceed the other specifications. In addition, section 1110.4 of the 2012 edition of the International Building Code requires VMS in transportation facilities and in emergency shelters to comply with ICC A117.1 unless equivalent information is provided audibly. The IBC, however, does not require the VMS, itself, to provide the audible message. For example, in a transportation facility, information equivalent to the VMS display can be provided through a public address system.

Question 18. In the final rule, the Board is considering incorporating by reference the requirements for VMS in ICC A117.1-2009—or its successor ICC A117.1-2015, if the standard has been finalized by that time—in order to make such signs more accessible to individuals who are blind or have low vision. The Board seeks comment on the advisability of incorporating by reference the requirements in ICC A117.1-2009 (or its successor) for variable message signs. Are there technologies that would allow a user to receive an audible message generated by the VMS sign? If so, the Board requests that commenters provide information regarding this technology. Until VMS can be made directly accessible to persons who are blind, we recognize that VMS would have to be paired with audible public address announcements. If VMS cannot be speech enabled, should the Board require VMS to, at least, be accessible to people with low vision?
