See also: Final Rule published to the Federal Register 1/18/17 that jointly updates requirements for ICT covered by Section 508 of the Rehabilitation Act and Section 255 of the Communication Act.

407.3 Tactilely Discernible.

At least one tactilely discernible input control shall be provided for each function and shall conform to 407.3.

EXCEPTION: Devices for personal use with input controls that are audibly discernable without activation and operable by touch shall not be required to be tactilely discernible.

407.3.1 Identification.

Input controls shall be tactilely discernible without activation and operable by touch. Where provided, key surfaces outside active areas of the display screen shall be raised above surrounding surfaces.

407.3.2 Alphabetic Keys.

Where provided, individual alphabetic keys shall be arranged in a QWERTY keyboard layout and the “F” and “J” keys shall be tactilely distinct from the other keys. Where the ICT provides an alphabetic overlay on numeric keys, the relationships between letters and digits shall conform to ITU-T Recommendation E.161 (incorporated by reference in Chapter 1).

407.3.3 Numeric Keys.

Where provided, numeric keys shall be arranged in a 12-key ascending or descending keypad layout. The number five key shall be tactilely distinct from the other keys.

Advisory 407.3.3 Numeric Keys. A telephone keypad and a keypad on a computer keyboard differ in one significant feature, ascending versus descending numerical order of the layout. Some keypads will have a double width zero key and decimal key instead of the asterisk and pound signs found on a telephone keypad. These examples conform to this provision.
