Apple: >>I designed the initial user interface concepts for iPad, iPod Nano, and half a dozen experimental hardware platforms. Initiated, designed, and prototyped over seventy concept projects, including radically reinvented interfaces for video editing, animation, drawing, learning, collaboration, mail, photos, and much more. Invented features for Mac OS X Lion. Worked with designers and engineers from all parts of Apple. Routinely presented to top-level management
Also, in general, direct manipulation of objects (mapped to real world gestures/physical object interaction) is not the end all be all of HCI. The use of abstraction in the pursuit of increased expressiveness and user input magnification is perfectly acceptable. Being able to immediately understand something is not more important than being able to efficiently accomplish a task repeatedly.
Whoa that is a pretty strong statement you just made there. I'd say there are two pretty strong and valid camps about this -- one saying its important to understand immediately and another saying tis important to do a depth of work effeciently. Both have extremely valid examples of why their theory is better.
If Apple was not able to use his inventions in a year - it's unlikely Apple would ever use these inventions efficiently.
I'm not buying it.
