Application programming interfaces for gesture operations

Abstract

At least certain embodiments of the present disclosure include an environment with user interface software interacting with a software application to provide gesture operations for a display of a device. A method for operating through an application programming interface (API) in this environment includes transferring a scaling transform call. The gesture operations include performing a scaling transform such as a zoom in or zoom out in response to a user input having two or more input points. The gesture operations also include performing a rotation transform to rotate an image or view in response to a user input having two or more input points.

AI Technical Summary

Benefits of technology

"The present patent describes various methods and interfaces for user interaction with software applications on devices. These methods include transferring function calls through application programming interfaces (APIs) for scrolling, gesturing, and animating operations, as well as responding to rubberbanding and scaling transforms. The patent also describes devices and machine-readable media that perform these methods. The technical effects of the patent include improved user experience and more efficient interaction with software applications on devices."

Problems solved by technology

The various types of devices may have a limited display size, user interface, software, API interface and / or processing capability which limits the ease of use of the devices.

These user interfaces can have difficulty interpreting the various types of user inputs and providing the intended functionality associated with the user inputs.
