Double tap standard time interval

Question

Is there any standard, for example, the ISO standard, for the interval (in milliseconds) between the taps (pressed on touch devices) that are supposed to be double-clicked? My guess is that it should be long enough to allow slower users to double-click, but not so long, which leads to errors.

Answer 1

I think this seems like a problem with clicking / dbl -click http://en.wikipedia.org/wiki/Double-click#Speed_and_timing

The maximum delay required for two consecutive clicks, which should be interpreted as a double click, is not standardized. According to the Microsoft MSDN website, the default time on Windows is 500 ms (one half second).

So, apparently, it is not standardized . I would say that pressing is slower or equal to clicking (this will depend on the relative position of the hand to the device), but still 500 ms sounds reasonable.

Answer 2

Warning: Speculation :)

Probably not. Something that is central to the “feel” of the user interface will not translate well to different types of input devices or even to different assemblies of the same type of device.

For example, one touchscreen can be much more sensitive than another. Another device may be more unstable and require more de-bouncing software and therefore more time to make a two-way distinction.

In addition, this parameter is usually configured for greater accessibility by those who are less dexterous (for example, children, the elderly and disabled).

For a direct counter example on Windows, this is configured:

If there is, no one sticks to it. I believe that most systems allow some kind of configuration for this. Some people (even with older systems using mice) cannot physically quickly click to invoke DoubleClick. They must change the system settings.
