2.1.1 requires all functionality of the content to be operable in a non-time-dependent manner through a keyboard interface. However, many Web sessions eventually time out, and there is no practical way to design the server software to avoid this. Even when the Web content complies with criterion 2.2.1 and 2.2.6, which in many cases requires the user have some control over such time-outs, that does not make it comply with 2.1.1.

Proposed Change:

Define "non-time-dependent manner" as "method that does not require user action within any period shorter than ten minutes", or else add a Note to 2.1.1 explaining that server-based session time-outs of at least some minimum duration are not considered part of the content.; Related issues: (space separated ids); WG Notes: [TEAMA] Discussed in the 03 August 2006 telecon: Resolution: Accept team a survey items which has unanimous consent: LC-603, LC-792, LC-854, LC-940, LC-1062, LC-1164, LC-1224 http://www.w3.org/WAI/GL/2006/08/03-wai-wcag-minutes.html {partial accept} DONE Change SC 2.1.1 to 2.1.1 All functionality of the content is operable through a keyboard interface without requiring specific timings for individual keystrokes, except where the task requires analog, time-dependent input. DONE add the following to Intent for 2.1.1: Examples of "specific timings for individual keystrokes" include situations where a user would be required to repeat or execute multiple keystrokes within a short period of time or where a key must be held down for an extended period before the keystroke is registered. DONE revise the note in the definition of "analog, time-dependent input" to read: Note: Most actions carried out by a pointing device can also be done from the keyboard (for example, clicking, selecting, moving, sizing). However, there is a small class of input that is done with a pointing device that cannot be done from the keyboard in any known fashion. This type of input can be best characterized by the fact that the outcome can only be achieved by moving the pointer in a smooth fashion at a certain rate. For example, in a watercolor program stroke width and transparency may depend on the rate of movement (and/or pressure) of a "brush". Another example would be a real-time helicopter flight simulator. Internal WD updated August 15. Response: http://lists.w3.org/Archives/Public/public-comments-wcag20/2007Jun/0300.html; Resolution: Time-outs are covered under another success criterion. This refers to not requiring individual keys to be pressed or released under particular time contraints. To make this clear, we have rewritten the SC to 2.1.1 All functionality of the content is operable through a keyboard interface without requiring specific timings for individual keystrokes, except where the underlying function requires input that depends on the path of the user's movement and not just the endpoints.; (Please make sure the resolution is adapted for public consumption)
