How will we handle multi-touch in Etoys?
1) Multiple Mice:
When you touch the screen with multiple fingers you get "many mice" So, how
can I get the mouseX and mouseY for each "mouse"? Thinking about this for
my version of Slice it. So I can imagine one way would be a collection of
mice, one could iterate through.
2) No Mouse Fat Fingers problem:
A while back I had a conversation with an expert (some 17 or 18 year old kid
who had built a Theremin remote control for his TV) and the idea came to me,
I asked him about the power consumption, costs and if there were any
interference issues and from the discussion it would seem this may be doable
within XO-3 constraints. It would operate similar to the Bamboo Fun tablet
which detects the stylus when it hovers over the tablet and you can move the
mouse without touching the tablet, then it clicks when you touch the tablet.
One issues I can foresee would be when you "hover" your finger over the
screen if the mouse pointer is right under your finger, it would block the
view of the pointer, so you would have to position the pointer "above" the
finger. But then when you touch you are not "clicking" where you touch.
Of course part of my problem my be I am thinking like a mouse ;)
