from Gestural Interfaces: A Step Backwards In Usability“There are several important fundamental principles of interaction design that arecompletely independent of technology: · Visibility (also called perceived affordances or signiﬁers) · Feedback · Consistency (also known as standards) · Non-destructive operations (hence the importance of undo) · Discoverability: All operations can be discovered by systematic exploration of menus · Scalability. The operation should work on all screen sizes, small and large. · Reliability. Operations should work. Period. And events should not happen randomly.All these are rapidly disappearing from the toolkit of designers.”Donald A. Norman and Jakob Nielsenhttp://www.jnd.org/dn.mss/gestural_interfaces_a_step_backwards_in_usability_6.html

Challenges for users Cause What can I act on and what do my actions mean? Effect Is there feedback, can I perceive it, and what does it tell me? What senses am I using? The minority report problem Do I have the physical or cognitive skill to perform a task? Learning curve How much time am I willing to invest in learning this system? Do I trust that the eventual reward is worth it?
Challenges for designers & inventorsTechnical proof of concept Design concept Hobbyist/fun User-centred design vs. Technical feasibility Design intention Uncovering new territory Hindsight
Meeting those challenges?Donʼt throw out the familiar. Conventions, metaphor,discoverability, consistency can all be helpful.Pay particular attention to sensory and physicalfactors.Provide feedback at the point of interaction,preferably with the same sense as used for the input.Design with intention, user test, iterate, etc.
