Left-handers push words when we write. It's not a natural motion, and the SMART Board™ takes southpaws back to the fountain pen days, when our hand would smudge the not-quite-dry ink.
When I write on a SMART Board™, my hand blocks the light. As I continue, my wrist, then my forearm block the light.
Many left-handers can write backwards, though most may be unaware of this. If you're lefty, try it for a few minutes. You may amaze yourself more than you already do.
Some of us can write backwards faster than forwards. I occasionally took notes in medical school backwards, then reverse the paper and hold it up to a light to read it.
So here's my idea for a new assistive technology--program the SMART Board to flip my witing into its mirror image as I write!
Take that, Sister Mary Barbara!
Other reasons I don't like SMART Boards™:That lag (try drawing lots of dots in a diffusion lesson
Hogs up my whiteboard space
The culture (All caps? Really? How precious....)
I secretly take it down for some periods...lots of glorious whiteboard underneath!
Drawing by DaVinci--I tweeted him, but he never wrote back....
