I read a previous post on discussions about designing UI for left or right hand users, but I thought they left out an important discussion when it comes to touch and tablet devices.
For example, I would imagine that devices which require the use of a stylus (where the operation is dependent on one hand entirely) would have some setting to allow the user to select their preference, or the device itself might be designed for a left handed person. It seems like for handwriting recognition software the direction would also be important because traditional stationery do not cater well for left handed people in general.
I would like to know if there are examples of where this issue has considerable impact in a digital platform, or if it becomes a non-issue because the interface can be customized more easily for a left-handed user.
