Abstract

Systems and methods for optical transmission of haptic display parameters are disclosed. One disclosed method includes receiving an image signal from an image sensor, the image signal associated with an image, determining a haptic signal based at least in part on the image signal, generating a haptic effect signal based at least in part on the haptic signal, and transmitting the haptic effect signal to a haptic output device.

Claims

1. A method comprising:

receiving an image signal from an image sensor, the image signal associated with an image;

determining a haptic signal based at least in part on the image signal;

generating a haptic effect signal based at least in part on the haptic signal; and

transmitting the haptic effect signal to a haptic output device.

2. The method of claim 1, wherein determining the haptic signal comprises evaluating the color of the image.

3. The method of claim 2, wherein determining the haptic signal comprises evaluating the lower 2 bits of each RGB value to determine a magnitude of the haptic effect.

4. The method of claim 1, wherein determining the haptic effect comprises determining a width of a drawing.

5. The method of claim 1, wherein determining the haptic effect comprises determining a width of a drawing.

6. The method of claim 1, wherein determining the haptic effect comprises determining one or more of the magnitude, modulation, or texture based of the haptic effect.

7. The method of claim 1, further comprising receiving a sensor signal from a sensor and wherein determining the haptic effect further comprises determining the haptic effect based at least in part on the sensor signal.

8. The method of claim 7, wherein the sensor comprises one of an accelerometer, gyroscope, compass, biosensor, or pressure sensor.
