Systems and methods for improving image tracking based on touch events

1. A method for outputting an image for presentation using an electronic device, the electronic device having a display refresh rate, the method comprising:

detecting, by the electronic device, one or more touch events received via a touch sensitive surface screen associated with the electronic device, each touch event having a touch event position;

generating, by the electronic device, a synthetic touch event position based on the one or more touch event positions, the synthetic touch event position calculated to coincide in time with a predicted time, the predicted time being within an offset relative to a display refresh time corresponding to the display refresh rate, wherein touch events detected within the offset are utilized for generating a subsequent synthetic touch event position; and

outputting data based at least in part one or more of the synthetic touch event position or a touch event position associated with the one or more touch events.

2. The method of claim 1 , further comprising:

generating an interpolated event position based at least in part on a touch event before and a touch event after the display refresh time, and outputting the data further based at least in part on the interpolated event.

3. The method of claim 2 , further comprising:

determining an error between the synthetic touch event position and the interpolated event position, and outputting the data further based at least in part on the error.

4. The method of claim 3 , further comprising progressively compensating the error over time and outputting the data further based at least in part on the compensation.

one or more processors in communication with the touch screen and the display; and

at least one memory in communication with the one or more processors and configured for storing data and instructions that, when executed by the at least one processor, cause the system to:

detect one or more touch events from the touch screen, each touch event having a touch event position;

generate a synthetic touch event position based on the one or more touch event positions, the synthetic touch event position calculated to coincide in time with a predicted time, the predicted time being within an offset relative to a display refresh time corresponding to the display refresh rate, wherein touch events detected within the offset are utilized for generating a subsequent synthetic touch event position; and

output data based at least in part one or more of the synthetic touch event position or a touch event position associated with the one or more touch events.

9. The system of claim 8 , wherein the instructions, when executed by the at least one processor, further cause the system to:

generate an interpolated event position based at least in part on a touch event before and a touch event after the display refresh time; and

output the data further based at least in part on the error.

11. The system of claim 8 , wherein the offset is before the refresh time.

12. The system of claim 8 , wherein the offset is after the refresh time.

13. The system of claim 8 , wherein the instructions, when executed by the at least one processor, further cause the system to:

estimate a velocity vector based on the one or more touch events

predicting a future velocity vector using an estimated acceleration vector based on the one or more touch events; and

generate a synthetic touch event position based at least in part on one or more of the velocity vector or the estimated acceleration vector.

14. The system of claim 8 , wherein each of the one or more touch events include a notification that the touch screen was touched.

15. The system of claim 14 , wherein the notification includes a time stamp.

16. A non-transitory computer-readable medium that stores instructions that, when executed by at least one processor in a system, cause the system to perform a method for outputting an image for presentation using an electronic device, the electronic device having a display refresh rate, the method comprising:

detecting, by the electronic device, one or more touch events received via a touch sensitive surface screen associated with the electronic device, each touch event having a touch event position;

generating, by the electronic device, a synthetic touch event position based on the one or more touch event positions, the synthetic touch event position calculated to coincide in time with a predicted time, the predicted time being within an offset relative to a display refresh time corresponding to the display refresh rate, wherein touch events detected within the offset are utilized for generating a subsequent synthetic touch event position; and

outputting data based at least in part on one or more of the synthetic touch event position or a touch event position associated with the one or more touch events.

17. The non-transitory computer-readable medium of claim 16 that further stores instructions that further causes the system to perform the method steps of:

generating an interpolated event position based at least in part on a touch event before and a touch event after the display refresh time; and
