TEITAC subcommittee report § 1194.25 Self Contained, Closed Products — 4/18/07
I. Material which can be described as “Changes to Existing Provisions”
- Modification – Material which modifies existing provisions.
- Rationale – Why is this change suggested?
- Estimate Economic Assessment. This field should contain the Subcommittee’s rough guess of expense to implement a revised provision. These changes should be measured from the current 508 standard only. For example, if the provision is not different, there is no net economic impact. Code as:
- “0” for negligible economic impact;
- “+” for minor economic impact;
- “++” for significant economic impact.
| Current provision | Keep current language? | Change in jurisdiction? | Modification | Rationale: Why is this change suggested? | Economic Assessment |
|---|---|---|---|---|---|
| 1194.25 (a) Self contained products shall be usable by people with disabilities without requiring an end-user to attach assistive technology to the product. Personal headsets for private listening are not assistive technology. | no | no | If any functionality of a hardware or software product is closed for any reason, including hardware, setting or policy, such that assistive technology for a particular user group cannot be used with the product, then the product functionality must be fully usable by that group without AT. (Headsets for private listening are not considered AT). | Self-contained is a functional characteristic of either hardware or software features of a product rather than of a class of products. This provision will apply to products that are partially or completely locked to AT and clarifies that other modes need to be provided in such cases. | 0 |
| 1194.25 (b) When a timed response is required, the user shall be alerted and given sufficient time to indicate more time is required. | yes | Software | N/A | Software provision applicable whether a feature is closed or open to AT. | 0 |
| 1194.25 (c) Where a product utilizes touchscreens or contact-sensitive controls, an input method shall be provided that complies with ยง1194.23 (k) (1) through (4). | Yes | Hardware | N/A | Controls, whether touch screen or mechanical, are a hardware function applicable to product features that are closed or open to AT. | 0 |
| 1194.25 (d) When biometric forms of user identification or control are used, an alternative form of identification or activation, which does not require the user to possess particular biological characteristics, shall also be provided. | No | General | Under Discussion | May need clarification that this provision applies to biometrics related to product usage rather than biometrics for other purposes. | 0 |
| 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. | yes | First sentence moved to hardware; second sentence moved to software. | Further discussion | This is two provisions and should be designated in hardware and software respectively. | 0 |
| 1194.25 (f) When products deliver voice output in a public area, incremental volume control shall be provided with output amplification up to a level of at least 65 dB. Where the ambient noise level of the environment is above 45 dB, a volume gain of at least 20 dB above the ambient level shall be user selectable. A function shall be provided to automatically reset the volume to the default level after every use. | not determined | not determined | N/D | N/D | N/D |
| 1194.25 (g) Color coding shall not be used as the only means of conveying information, indicating an action, prompting a response, or distinguishing a visual element. | yes | General | N/A | Applicable to all products hardware/software, closed/open to AT | 0 |
| 1194.25 (h) When a product permits a user to adjust color and contrast settings, a range of color selections capable of producing a variety of contrast levels shall be provided. | yes | software | N/A | This is a function of software. | 0 |
| 1194.25 (i) Products shall be designed to avoid causing the screen to flicker with a frequency greater than 2 Hz and lower than 55 Hz. | no | software | 55 HZ modified to 50 HZ | Not correctly implemented from the EITAAC | 0 |
| 1194.25 (j) Products which are freestanding, non-portable, and intended to be used in one location and which have operable controls shall comply with the following: (1) 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 (see Figure 1 of this part). (2) 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. (3) 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. (4) Operable controls shall not be more than 24 inches behind the reference plane (see Figure 2 of this part). | yes | hardware | N/A | Applies to any stand alone hardware | 0 |
