@section ptraccel-touchpad Pointer acceleration on touchpads
Touchpad pointer acceleration uses the @ref ptraccel-linear profile, with a
constant deceleration factor applied. The user expectation of how much a
pointer should move in response to finger movement is different to that of a
mouse device, hence the constant deceleration factor.
Touchpad pointer acceleration uses the same approach as the @ref
ptraccel-linear profile, with a constant deceleration factor applied. The
user expectation of how much a pointer should move in response to finger
movement is different to that of a mouse device, hence the constant
deceleration factor.
