1. A method for enabling non-visual use of an electronic device comprising:
- detecting a touch event on a touch-sensitive display at a location;
determining whether the touch event is a first type of touch event or a second type of touch event, the first type of touch event and the second type of touch event each comprising at least one gesture; and
if touch event is the first type of touch event, selectively activating a first subset of a plurality of piezoelectric actuators; and
if the touch event is the second type of touch event, selectively activating a second subset of the plurality of piezoelectric actuators;
wherein each of the plurality of piezoelectric actuators share a common electrode.

Abstract
Systems, methods, computer-readable media, and other means are described for utilizing touch-based input components that provide localized haptic feedback to a user. The touch-based input components can be used and/or integrated into any type of electronic device, including laptop computers, cellular telephones, and portable media devices. The touch-based input components can use, for example, a grid of piezoelectric actuators to provide vibrational feedback to a user, while the user scrolls around a click wheel, slides across a trackpad, or touches a multi-touch display screen.

3. A user input component for an electronic device comprising:
-
a touch-sensitive surface that detects a touch event at a location; a grid of piezoelectric actuators overlaying the touch-sensitive surface, each of the grid of piezoelectric actuators sharing a common electrode; circuitry to determine whether the touch event is a first type of touch event or a second type of touch event; circuitry to selectively activate a first subset of the piezoelectric actuators included in the grid of piezoelectric actuators at the location of the touch event on the touch-sensitive surface if the touch event is a first type; and circuitry to selectively activate a second subset of the piezoelectric actuators included in the grid of piezoelectric actuators at the location of the touch event on the touch-sensitive surface if the touch event is a second type wherein; the first type of touch event and the second type of touch event each comprises at least one gesture. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11)
