Abstract

Disclosed are methods, apparatus, systems, and computer readable storage media for retrieving data while scrolling through a list of items in a user interface. A display device can display initial data of at least a first presentation of a first one or more items in a list of items. A user input can be received by the display device to cause scrolling through the list of items in the user interface. An initial scrolling velocity can be calculated responsive to the user input, and a second presentation of a second one or more items in the list of items that corresponds to an anticipated stopping of the scrolling can be predicted in accordance with the initial scrolling velocity and a deceleration rate. Data to be displayed in the second presentation can be retrieved before the stopping of the scrolling.

Claims

1. A computer-implemented method for retrieving data while scrolling through a list of items in a user interface, the method comprising:

displaying initial data of at least a first presentation of a first one or more items in a list of items in a user interface of a display device;

receiving a user input to cause scrolling through the list of items in the user interface;

calculating an initial scrolling velocity responsive to the user input;

predicting, in accordance with the initial scrolling velocity and a deceleration rate, a second presentation of a second one or more items in the list of items that corresponds to an anticipated stopping of the scrolling; and

retrieving data to be displayed in the second presentation before the stopping of the scrolling.

2. The method of claim 1, further comprising:

displaying the retrieved data in the second presentation in the user interface of the display device.

3. The method of claim 2, wherein displaying the retrieved data in the second presentation occurs before the stopping of the scrolling.

4. The method of claim 1, wherein the first presentation is a first page having a position in a sequence of pages, and the second presentation is a second page in the sequence.

5. The method of claim 4, wherein one or more third pages are disposed between the first page and the second page in the sequence.

6. The method of claim 4, wherein calculating an initial scrolling velocity includes:

determining a time interval corresponding to scrolling across the first page.

7. The method of claim 4, further comprising:

retrieving additional data of one or both of a preceding page and a subsequent page with respect to the second page; and

displaying the additional data in the user interface of the display device.

8. The method of claim 1, wherein each item in the list of items has a uniform height dimension for display in the user interface.

9. The method of claim 1, further comprising:

displaying placeholder data in the list of items between the display of the first presentation and the display of the second presentation while the scrolling occurs.

10. The method of claim 1, further comprising:

determining that the initial scrolling velocity is greater than a threshold scrolling velocity.

11. The method of claim 1, further comprising:

storing the retrieved data in a database of the display device.

12. The method of claim 1, further comprising:

retrieving the initial data from a database of the display device.

13. The method of claim 1, further comprising:

determining a cutoff scrolling velocity, wherein retrieving the data to be displayed in the second presentation occurs before the cutoff scrolling velocity is reached.

14. The method of claim 1, wherein the display device is one of:

a smartphone, a laptop, a tablet, a wearable display device, and a desktop computer.

15. The method of claim 1, wherein the display device is part of one of:

a vehicle, a consumer appliance, a sensor, a robot, and an electronic product.

16. A display device comprising:

a display; and

one or more processors configured to execute one or more instructions to;

display initial data of at least a first presentation of a first one or more items in a list of items in a user interface of the display;

receive a user input to cause scrolling through the list of items in the user interface;

calculate an initial scrolling velocity responsive to the user input;

predict, in accordance with the initial scrolling velocity and a deceleration rate, a second presentation of a second one or more items in the list of items that corresponds to an anticipated stopping of the scrolling; and

retrieve data to be displayed in the second presentation before the stopping of the scrolling.

17. The display device of claim 16, wherein the one or more processors are configured to execute one or more instructions to:

display the retrieved data in the second presentation in the user interface of the display before the stopping of the scrolling.

18. The display device of claim 16, wherein the one or more processors are configured to execute one or more instructions to:

display placeholder data in the list of items between the display of the first presentation and the display of the second presentation while the scrolling occurs.

19. A non-transitory computer-readable storage medium storing instructions executable by a display device to perform a method for retrieving data while scrolling through a list of items in a user interface, the method comprising:

displaying initial data of at least a first presentation of a first one or more items in a list of items in a user interface of a display device;

receiving a user input to cause scrolling through the list of items in the user interface;

calculating an initial scrolling velocity responsive to the user input;

predicting, in accordance with the initial scrolling velocity and a deceleration rate, a second presentation of a second one or more items in the list of items that corresponds to an anticipated stopping of the scrolling; and

retrieving data to be displayed in the second presentation before the stopping of the scrolling.

20. The non-transitory computer-readable storage medium of claim 19, the method further comprising:

displaying the retrieved data in the second presentation in the user interface of the display device before the stopping of the scrolling.
