The 3 seconds can be difficult to measure. For example, when the animation
is displayed to indicate a page loading, or a module installing. Here the
time would depend on the speed of the connection or the computer.
Also, animations should be further defined. Is an hourglass or a progress
bar an animation? Or what are we doing with purely decorative animations? I
would make the distinction between decorative and informative animations,
the same way as it exists in connection with images.

Subject: [teitac-websoftware] 1194.21 h to ISO-9241-171
(g went out in an out of sequence message)
Here is 1194.22 h, as in Henry, mapping 1194.21 to iso 9241-171
Summary: I am not sure how folks feel about the 3 second rule in the iso
standards, but the essense is the same in both (provide alternatives to
(h) When animation is displayed, the information shall be displayable in at
least one non-animated presentation mode at the option of the user
10.8.1 Provide non-animated alternatives to animations When animation is
displayed that will last for more than three seconds, and the user is
expected to carry out other activities at the same time, software shall give
the user the option to choose an alternative non-animated version of the
same content. If the animation is not task relevant then a version where the
non-task-relevant item is missing would conform.
