Abstract

A method for providing a mechanism by which different user interface effects may be performed for different classifications of gestures may include receiving an indication of a touch event at a touch screen display, determining a gesture classification and an implementation characteristic classification for the touch event, and enabling provision of substantively different user interface effects for respective different implementation characteristic classifications of the gesture classification. A corresponding apparatus and computer program product are also provided.

Claims

1. A method comprising:

receiving an indication of a touch event at a touch screen display;

determining a gesture classification and an implementation characteristic classification for the touch event, wherein determining a gesture classification comprises determining a type of gesture corresponding to the touch event; and

for a respective type of gesture, enabling provision of substantively different user interface effects for respective different implementation characteristic classifications of the respective type of gesture, wherein enabling provision of substantively different user interface effects comprises causing provision of an object level zoom effect in response to a first implementation characteristic classification of the respective type of gesture and causing provision of a proportional zoom effect in response to a second implementation characteristic classification of the same respective type of gesture, wherein the object level zoom effect causes borders of an object to be selected within an image so as to maintain the object within a resulting image while reducing background information with the object that is maintained within the resulting image being based upon an importance of the object, and wherein the proportional zoom effect is performed at a rate of zooming proportional to an implementation characteristic.

2. The method of claim 1, wherein determining the implementation characteristic classification comprises determining a status of an implementation characteristic used to initiate a gesture associated with the gesture classification determined for the touch event relative to a threshold.

3. The method of claim 1, wherein enabling provision of substantively different user interface effects for respective different implementation characteristic classifications of the gesture classification comprises causing provision of a first user interface effect in response to a first implementation characteristic classification and causing provision of a second user interface effect in response to a second implementation characteristic classification, the first and second user interface effects being substantively different from each other by other than a matter of degree.

4. The method of claim 1, wherein the first implementation characteristic classification of the respective type of gesture comprises a fast pinch event having a speed of implementation that exceeds a threshold speed.

5. The method of claim 4, wherein causing provision of the object level zoom effect comprises providing an instantaneously generated zoom view to a predefined zoom level relative to a full screen view of a content item in response to the fast pinch event.

6. The method of claim 4, wherein causing provision of the object level zoom effect comprises generating a zoom view on a predetermined portion of interest within an image.

7. The method of claim 6, wherein generating the zoom view of the predetermined portion of interest comprises providing an instantaneously generated zoom view of a cropped portion of the image, the cropped portion including an object and eliminating background portions surrounding the object in response to the fast pinch event.

8. The method of claim 4, wherein causing provision of the object level zoom effect comprises providing an instantaneously generated zoom view of a previously generated zoom level view in response to reversing a direction of the fast pinch event used to generate an image level view subsequent to the previously generated zoom level view.

19. The method of claim 1, wherein determining the implementation characteristic classification of the touch event comprises determining the implementation characteristic classification based upon at least one of speed if a touch-related movement or pressure associated with the touch event.

20. The method of claim 1, wherein causing provision of the object level zoom effect comprises causing provision of the object level zoom effect based upon tagged objects within an image presented upon the touch screen display or based upon a plurality of predefined zoom levels.

9. An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the processor, cause the apparatus to at least:

receive an indication of a touch event at a touch screen display;

determine a gesture classification and an implementation characteristic classification for the touch event, wherein determining a gesture classification comprises determining a type of gesture corresponding to the touch event; and

for a respective type of gesture, enable provision of substantively different user interface effects for respective different implementation characteristic classifications of the respective type of gesture, wherein enabling provision of substantively different user interface effects comprises causing provision of an object level zoom effect in response to a first implementation characteristic classification of the respective type of gesture and causing provision of a proportional zoom effect in response to a second implementation characteristic classification of the same respective type of gesture, wherein the object level zoom effect causes borders of an object to be selected within an image so as to maintain the object within a resulting image while reducing background information with the object that is maintained within the resulting image being based upon an importance of the object, and wherein the proportional zoom effect is performed at a rate of zooming proportional to an implementation characteristic.

10. The apparatus of claim 9, wherein the at least one memory and the computer program code are configured, with the processor, to determine the implementation characteristic classification by determining a status of an implementation characteristic used to initiate a gesture associated with the gesture classification determined for the touch event relative to a threshold.
