I've looked through pages on left handedness and failed to get the answers I'm looking for.
a) Why is left handedness not considered as a disability in design terms? No offence. But when I checked Universal Design 7 elements, it focuses on right handed, disabled, children and elderly. Therefore, when a product/item is considered ergonomics, it will not to left handed. This could lead to discomfort and long term injury.
b) What would be the criteria or requirements in order to make an item non biased towards right or left handers? So that lefties also could enjoy using a product.
