Meeting 4 Report
Section 1 – No changes recommended
1194.26 (a) All mechanically operated controls and keys shall comply with § 1194.23 (k) (1) through (4).
1194.23 (k) (1) Controls and keys shall be tactilely discernible without activating the controls or keys.
1194.23 (k) (3) If key repeat is supported, the delay before repeat shall be adjustable to at least 2 seconds. Key repeat rate shall be adjustable to 2 seconds per character.
1194.23 (k) (4) The status of all locking or toggle controls or keys shall be visually discernible, and discernible either through touch or sound.
1194.25 (j) (1) Products which are freestanding, non-portable, and intended to be used in one location and which have operable controls shall comply with the following. The position of any operable control shall be determined with respect to a vertical plane, which is 48 inches in length, centered on the operable control, and at the maximum protrusion of the product within the 48 inch length on products which are freestanding, non-portable, and intended to be used in one location and which have operable controls.
1194.25 (j)(3) Products which are freestanding, non-portable, and intended to be used in one location and which have operable controls shall comply with the following, Where any operable control is more than 10 inches and not more than 24 inches behind the reference plane, the height shall be 46 inches maximum and 15 inches minimum above the floor.
1194.25 (j)(4) Products which are freestanding, non-portable, and intended to be used in one location and which have operable controls shall comply with the following. Operable controls shall not be more than 24 inches behind the reference plane.
Section 2 – Recommended language changes
Add wireless as type of connector to 1194.26 (d)
Where provided, at least one of each type of expansion slots, ports, connectors, and wireless connections shall comply with publicly available industry standards.
Reword 1194.23 (k) (2) from:
Controls and keys shall be operable with one hand and shall not require tight grasping, pinching, or twisting of the wrist. The force required to activate controls and keys shall be 5 lbs. (22.2 N) maximum.
to
Controls and keys shall be operable with one hand and shall not require pinching, twisting of the wrist, or tight grasping. The force required to activate controls and keys shall be 5 lbs. (22.2 N) maximum.
Section 3 – Still under discussion
Change maximum height from 54 to 48 inches per recent ADAAG changes
1194.25 (j)(2) Products which are freestanding, non-portable, and intended to be used in one location and which have operable controls shall comply with the following. Where any operable control is 10 inches or less behind the reference plane, the height shall be 54 inches maximum and 15 inches minimum above the floor.
Clarification of control types (mechanical, touch sensistive, touch dependent (biometric))
Mechanical or physical controls language acceptable. We have tried to categorize: Human Touch, Light Touch, other physical. But it’s difficult to categorize, since there either are currently, or will be in the future, touch controls that don’t fit into our categories.
Committee is working on language that defines the higher level functions associated with light touch and human touch controls.
Physical controls would be covered by existing mechanical control language.
Audio Access Points
There is concern over audio ports access, because although they are standard, they cannot provide full accessibility by themselves. Need to deal with audio ports specially. Currently, audio ports are referenced in:
1194.25 (e) When products provide auditory output, the audio signal shall be provided at a standard signal level through an industry standard connector that will allow for private listening. The product must provide the ability to interrupt, pause, and restart the audio at anytime.
We have proposed a language change from "Standard Connector" to “Standard Interconnections”.
Additionally, there is a recommendation to separate this into two distinct elements relative to product control.
Addition of object coding guidance.
This is based on a provision from SW that 1194.21(i) Color coding shall not be used as the only means of conveying information, indicating an action, prompting a response, or distinguishing a visual element. However, contrast is likely different (as there would be lower contrast requirements for hardware labels as compared to full pages of text, etc). A label needs to be discernible (visual, tactile, auditory).
Blinking LEDs
Big discussion over what constitutes flash and flicker. Concern for flash is the distraction (for people with learning disabilities, for example). Concern for flicker is seizure inducing Gregg V and Tom Albin agreed to review existing literature (including ISO) and will draft language around flicker.
JIS HW X8341
Committee reviewed the standard and has identified potentially applicable sections and will continue to discuss.
