Abstract: A system and method for providing a touch input interface for information, computing and control devices. In accordance with an embodiment, the systems and methods described herein, in a high level conceptual embodiment, can be used to provide interface devices and methods that naturally and organically present a preview of the action that will take place, if and only if the element (or elements) of the interface that is (are) currently indicated, is (are) definitely commanded by further confirmation. Otherwise the state of the device will be maintained, and the display will be restored to its previous state if no such action is taken, and/or if the indication is removed or changed. In most embodiments, the feedback is to be presented in a natural way that does not distract, such as in the line of sight.

Abstract: A system and method for providing an interface for an electronic or computing device. In one embodiment, the invention includes a keyboard positioned adjacent to the posterior side of the computing device in such a way that the user can operate the device in an easy and convenient manner, while at the same time maximizing the amount of available display space to the user viewing the anterior side of the device. In this embodiment the user operates the keyboard while it is hidden from view behind the display. The invention also provides several mechanisms that allow the user to become familiar with this approach to operating the device, some of which are applicable to the improvement of standard keyboards for many common purposes and uses. These mechanisms include, but are not limited to, appropriately spaced keys, chorded keyboards, tactile feedback mechanisms, and key indication, selection and verification methods.
