All functionality should be accessible via pointer input devices, for example, via a mouse pointer, a finger interacting with a touch screen, an electronic pencil/stylus, or a laser pointer.
-People operating pointer input devices may not be able to carry out timed or complex gestures. Examples are drag-and-drop gestures and on touch screens, swiping gestures, split taps, or long presses. This Guideline does not discourage the provision of complex and timed gestures by authors. However, where they are used, an alternative method of input should be provided to enable users with motor impairments to interact with content via single untimed pointer gestures.

This Guideline does not discourage the provision of complex and timed gestures by authors. However, where they are used, an alternative method of input should be provided to enable users with motor impairments to interact with content via single untimed pointer gestures.
Often, people use devices that offer several input methods, for example, mouse input, touch input, keyboard input, and speech input. These should be supported concurrently as users may at any time switch preferred input methods due to situational circumstances, for example, the availability of a flat support for mouse operation, or situational impediments through motion or changes of ambient light.
A common requirement for pointer interaction is the ability of users to position the pointer over the target. With touch input, the pointer (the finger) is larger and less precise than a mouse cursor. For people with motor impairments, a larger target makes it easier to successfully position the pointer and activate the target.
The intent of this success criterion is to help users who may have trouble activating a small target because of hand tremors, limited dexterity, or other reasons. If the target is too small, it may be difficult to aim at the target. Mice and similar pointing devices can be hard to use for these users, and a larger target will help them greatly in having positive outcomes on the web page.
Touch is particularly problematic as it is an input mechanism with coarse precision. Users lack the same level of fine control as on inputs such as a mouse or stylus. A finger is larger than a mouse pointer, and generally obstructs the user's view of the precise location on the screen that is being touched/activated.
-The issue can be further complicated for responsive and mobile sites that need to accommodate different types of fine and coarse inputs (for example, a site that can be accessed on a traditional desktop or laptop with a mouse, as well as on a tablet or mobile phone with a touch screen).

While this criterion defines a minimum target size, it is recommended that larger sizes are used to reduce the possibility of unintentional actions. This is particularly relevant if any of the following are true:
Remembering a site-specific password is a cognitive function test. Such tests are known to be problematic for many people with cognitive disabilities. Whether it is remembering random strings of characters, or a pattern gesture to perform on a touch screen, cognitive function tests will exclude some people. When a cognitive function test is used, at least one other authentication method must be available which is not a cognitive function test.

Some CAPTCHA systems have an audio alternative of the visible text. If the user needs to transcribe this audio, it cannot be used to meet the Alternative exception.
