your statement that even sighted folks work more efficiently with mouse and keyboard than touch-screen is completely inaccurate. This is a field which is constantly and thoroughly being studied. Research papers are published extremely regularly on the topic.
First, when touch-screen interfaces are used in information kiosks rather than visual displays with keypads and navigation devices, user error is reduced from 18-25% to 6-10%. And, this is consistent across every topic / field which has been studied thus far. Second, the world record for fastest typing speed on a mobile device in 2011 was held by a person using a touch-screen device. I have not checked more recent numbers, but considering all the other studies I have analysed over the past few years, I would not be surprised if touch-screen devices continue holding speed records for data entry. Third, there is an upper limit on how many keyboard command shortcuts a person is able to maintain in one's active memory. Touch-screens, on the other hand, with their immediate visual response to haptic activation, do not suffer from the same limitation. It is comforting for us to tell ourselves that sighted people do better with keyboards just like we do. However, even though we know people who match what we wish so much to believe, research from around the world is continually proving the opposite to actually be the case.
