Re: Revised Pointer Target Spacing

Hi Alastair

I've been out of the issue loop over the last month because of an
inter city move of home and office... now having read through the threads,
yes there are significant issues with the SC.

   1. high impact on designers (which is always hard to sell)
   2. Some believe it has the highest impact on conformance of existing
   sites of all the new SCs since WCAG 2.0
   3. high impact on testing, which increases the cost of audits for
   companies
   4. It appears that the benefits are questionable in a world where
   browser zoom is highly customizable
   5. There are significant questions about whether it might end up with a
   negative impact on target size
   6. With the new 26px by 26px proposal, issue #1 above is minimized but
   issues #2-4 above seem to remain, especially #3 & 4

Some studies have suggested that for people with difficulties around motor
control of the arm and/or hand, that 100px is the minimum target size. It
seems like we may need to rely on personalization settings, browser AT
(that increase button sizes on the client side) .

I see the options as:

   1. put it out there with the Mobile TF 26px proposal
   2. Introduce a fallback SC that basically says, "don't interfere with
   the user's attempt to increase button size" (like the text spacing SC
   1.4.12)
   3. drop the SC and focus our time on other more viable improvements for
   2.2 noting that we ran into these same issues when trying to make this SC
   work for 2.1


Cheers,

David MacDonald
