Abstract

An apparatus is provided that includes a graphic overlay or display for a touch-sensitive surface with which an object comes into contact. The touch-sensitive surface is divided into a plurality of regions each of a number of which is associated with a distinct set of one or more of the plurality of gestures, where the plurality of gestures are associated with a respective plurality of functions of a software application operable by a processor. According to this aspect, the graphic overlay or display visibly depicts the regions and a layout of the regions into which the touch-sensitive surface is divided. The apparatus may further include a touch-feedback interface configured to provide touch feedback indicative of the gesture associated with the respective region within which the touch-feedback interface is disposed.

wherein the touch-feedback interface comprises one or more elongated elements the length of each of which extends along the predetermined direction, and the width of each of which extends across the predetermined direction, wherein the length is a longer dimension than the width, and the one or more elongated elements include one or more projections or indentions, and

wherein the touch-feedback interface is shaped to stimulate with a user a first tactile or haptic perception associated with the distinct set of one or more of the plurality of gestures associated with the respective region in instances in which the user drags the object over the touch-feedback interface along the length of the one or more elongated elements, and a second, different tactile or haptic perception associated with the distinct set of one or more of the plurality of gestures associated with the respective region in instances in which the user drags the object over the touch-feedback interface along the width of the one or more elongated elements.

2. The apparatus of claim 1, wherein the graphic overlay includes a set of one or more uniquely-placed contacts that, when the overlay is placed on the touch-sensitive surface, are detectable by the touch-sensitive surface and interpretable to correspond to the regions and the layout of the regions.

3. The apparatus of claim 1, wherein at least one of the one or more elongated elements is formed of a plurality of smaller, similarly-shaped elements, and wherein the smaller, similarly-shaped elements include projections or indentions.

4. The apparatus of claim 1, wherein the gesture associated with the respective region within which the touch-feedback interface is disposed comprises a movement interaction defining omnidirectional movement in any direction in a plane parallel to the graphic overlay, and

wherein the touch-feedback interface comprises a plurality of similarly-shaped elements arranged in a matrix of elements, wherein the similarly-shaped elements include projections or indentions, and

wherein the touch-feedback interface is shaped to stimulate with a user the same tactile or haptic perception in instances in which the user drags the object over the touch-feedback interface in any direction in the plane parallel to the graphic overlay.

5. The apparatus of claim 1, wherein the gesture associated with the respective region within which the touch-feedback interface is disposed comprises a movement interaction defining bidirectional movement in a predetermined direction, the function associated with the gesture comprising a rate-varying function, and

wherein the touch-feedback interface comprises a plurality of elongated elements each of which has an associated velocity with which the function is capable of being carried out.

6. The apparatus of claim 1, wherein the touch-feedback interface comprises a plurality of touch-feedback interfaces disposed on the graphic overlay within a respective plurality of regions depicted by the graphic overlay, the touch-feedback interfaces comprising structures shaped to provide touch feedback indicative of the distinct sets of gestures associated with the respective regions within which the touch-feedback interfaces are disposed, the gesture associated with at least one of the respective regions differing from the gesture associated with at least one other of the respective regions.

7. The apparatus of claim 1, wherein touch feedback associated with a first region of the two or more regions is indicative of a first set of distinct gestures for performing the gesture input using the first region, wherein touch feedback associated with a second region of the two or more regions is indicative of a second set of distinct gestures for performing the gesture input using the second region, wherein the first set of distinct gestures is different from the second set of distinct gestures, and wherein touch feedback provided by the first region is different than touch feedback provided by the second region.

8. An apparatus comprising:
