Abstract

Methods and apparatus are provided for a user interface with haptic feedback. The user interface includes a display element configured to display a visual image; a touch screen panel coupled to the display element and configured to receive a user input; a controller coupled to the touch screen panel and configured to generate a feedback signal based on the user input; a first actuator coupled to the controller and the touch screen panel and configured to operate in a first mode based on the feedback signal; and a second actuator coupled to the controller and the touch screen panel and configured to operate in a second mode based on the feedback signal.

2. The user interface of claim 1, wherein the first mode has a first frequency and the second mode has a second frequency, different that the first frequency.

3. The user interface of claim 1, wherein the first mode includes a third pattern of peaks, the first actuator being positioned at one of the peaks of the third pattern of peaks.

4. The user interface of claim 3, wherein the second mode includes a fourth pattern of peaks, the second actuator being positioned at one of the peaks of the fourth pattern of peaks.

5. The user interface of claim 1, wherein the first mode is a (2, 2) mode and the second mode is a (3, 3) mode.

6. The user interface of claim 1, wherein the first mode is a (2, 2) mode and the second mode is a (4, 3) mode.

7. The user interface of claim 1, wherein the perimeter is rectangular with first, second, third, and fourth sides, a first corner joining the first and second sides, a second corner joining the second and third sides, a third corner joining the third and fourth sides, and a fourth corner joining the fourth and first sides.

8. The user interface of claim 7, wherein the first actuator is positioned at the first side and the second actuator is positioned at the second corner.
