hm ... I thought the more different movements you do, the less repetitive the whole thing would be ?
anyways, as the visionary you claim to be, aren't you happy those mobile devices have input methods that do not use a gui (as Siri or the Google Voice Search)?
or even Google Now which tries to read your mind?
but then this speech recognition might cause a sore throat and the mind reading a headache.
In order to use a touch device with any sort of efficiency you need an external keyboard. So now you not only have to make the repetitive movements of the keyboard,but also switch from keyboard to screen all the time. Which is repetitive.
And since putting a cursor on the right place, selecting text etc. using touch is a nightmare, many people added a mouse as well to their tablets, making it a triple whammy.
The thing just isn't a valid solution for professional run of the mill business use where data entry/retrieval are the core use of computers. In actual fact a tablet with a keyboard and a mouse is a very expensive, impractical and cumbersome way to do something you could do already using cheaper more practical existing equipment. It's just not as cool, but in business we don't go for cool, we go for making a profit with the least cost, and the least health risks for the employees.
Tablets are a niche, but due to marketing and people wanting gadgets it sells like hotcakes.
As soon as voice recognition actually recognizes anything else then perfectly pronounced english, and doesn't have an error rate that makes me lose more time correcting then i gain using it i'll be the first to use it. But now if my dog barks i can tell you some really weird text appears. Also various background noises beyond your control make it haphazard form of interaction.
If a computer comes around that really can read my mind how do i prevent it from not typing things like: f you ahole when my boss bothers me?
Not really practical.
