For my money he is spot on both in the statement that the best 
experiences have design specifically for the users, and that this is not 
an approach that is going to or even should be adopted in most cases 
where they don't have the resources to maintain it properly.

It is difficult to reconcile the gestures that he proposes with readily 
available technology of today, although there is no reason why the 
technology should remain hard to find - it has been developed years ago. 
In a use of mice that might make sense for people who don't actually see 
where the mouse is, Opera already allows for a number of gestures - some 
usability work with that might be a good test for the more speculative 
parts of the article. Finding a spot in 3-dimensional space is often 
very hard for people who are blind, but making a gesture which involves 
directions but not precise positioning is easier. (This is not perfectly 
true. People manage to light a cigarette wherever their head. But it is 
an oft-repeated action for most smokers...)
