Hi,

Not sure how to get this concern to the people who've designed the Android 
P 'Pill' button that replaces the traditional Android navigation buttons, 
so I'm posting here in the hope that someone useful will see it.

I'm left handed. There are approximately 10% of people in the world who are 
left handed. In comparison there are about 4.5% of people globally who are 
colour blind.

As phone UIs move more and more towards gesture based controls, left 
handers are increasingly struggling to use these new input mechanisms. 

For a typical left hander, you hold your phone in your right hand, and 
control it with your left. We already have to suffer the volume control on 
most phones being on the wrong side, and in many cases the 
screen-wake/power button too.  Now as Android P's details are being 
announced, I read that the Pill button works like so:

"To quickly switch between apps without launching multi-tasking view, press 
down on the pill-shaped button and drag it to the right to shuffle through 
recent apps. You can also flick the same button quickly to jump straight to 
the last app you were using." [1]

For a left handed person, swiping right is actually 'pushing right', it's 
almost impossible to accurately separate 'swipe' from 'flick' when you are 
'pushing'.  if you are right-handed try a quick demonstration of flicking 
left vs swiping left. It is a magnitude harder as your hand is not flicking 
outwards, but is pushing inwards.

Therefore I am asking the Android UI engineers to PLEASE think about left 
handers during the UI development. Although not officially recognised, we 
do have a disability and as Androids increasingly gesture based input 
system favours right handers, it discriminates against us.

As my opening states, there are double the amount of us than colour blind 
people, but accessibility systems always focus on high contrast colour 
schemes for the latter group, but we never get alternate input systems.

Thanks for reading,
