Abstract

Systems and methods for stabilizing haptic touch panels or touch surfaces are disclosed. For example, one disclosed system includes a housing having a base; and a touch sensitive input device. The apparatus further includes a first support member coupled to the base via a first hinge and coupled to the touch sensitive input device via a second hinge; a second support member coupled to the base via a third hinge and coupled to the touch sensitive input device via a fourth hinge; wherein the first support member and the second support member are configured to facilitate movement of the touch sensitive input device in a first degree of freedom.

Claims

1. A system, comprising:

a housing having a base;

a touch sensitive input device;

a first support member coupled to the base via a first hinge and coupled to the touch sensitive input device via a second hinge;

a second support member coupled to the base via a third hinge and coupled to the touch sensitive input device via a fourth hinge; and

wherein the first support member and the second support member are configured to facilitate movement of the touch sensitive input device in a first degree of freedom.

2. The system of claim 1, further comprising an actuator coupled to the touch sensitive input device, the actuator configured to provide haptic feedback.

3. The system of claim 2, wherein the actuator comprises an electric motor, an electromagnetic actuator, a voice coil, a linear resonant actuator, a shape memory alloy, or an electro-active polymer.

4. The system of claim 2, wherein the actuator does not bear the load of the touch sensitive input device.

5. The system of claim 1, wherein the first support member is positioned substantially opposite the second support member.

6. The system of claim 1, wherein

the first hinge comprises a first pin anchoring the first support member to the first hinge;

and

the second hinge comprises a second pin anchoring the first support member to the second hinge.

7. The system of claim 1, wherein the touch sensitive input device is a touch panel.

8. The system of claim 1, wherein the touch sensitive input device is substantially rigid.

9. The system of claim 1, wherein the touch sensitive input device is configured to move in a lateral degree of freedom.

10. The system of claim 1, wherein the touch sensitive input device is configured to resist displacement in a second degree of freedom.

11. The system of claim 1, wherein the touch sensitive input device is substantially fixed in a vertical degree of freedom.

12. A system, comprising:

a housing having a base;

a touch sensitive input device;

a first support member coupled to the base via a first flexure and coupled to the touch sensitive input device via a second flexure;

a second support member coupled to the base via a third flexure and coupled to the touch sensitive input device via a fourth flexure; and

wherein the first support member and the second support member are configured to facilitate movement of the touch sensitive input device in a first degree of freedom..

13. A system configured to stabilize a touch panel, the system comprising:

a housing having a base;

a touch panel positioned above the base;

a processor in communication with the touch panel and configured to receive input signals from the touch panel;

an actuator coupled to the touch panel, and configured to provide haptic feedback to the touch panel, the actuator in communication with the processor and configured to receive vibration signals from the processor;

a first support member coupled to the base via a first hinge and coupled to the touch panel via a second hinge;

a second support member coupled to the base via a third hinge and coupled to the touch panel via a fourth hinge, the second support member positioned substantially opposite to the first support member; and

wherein the first support member and the second support member are configured to suspend the touch panel above the housing, and wherein the first support member and the second support member are configured to support movement of the touch panel in a lateral degree of freedom.
