METHOD OF MOMENTUM BASED ZOOM OF CONTENT ON AN ELECTRONIC DEVICE

摘要

A method of interacting with a user interface displaying content on a display of an electronic device is provided. A zoom gesture is detected to modify a zoom level of the content displayed on the user interface. A momentum or kinetic value for the zoom gesture is determined and a final zoom level based on the determined momentum value of the zoom gesture is determined. The animation of the transition to the final zoom level can be adjusted to display the content on the user interface at the determined final zoom level. The content may be a webpage in a web browser where the zoom gesture is performed on regions within the content. The momentum of the zoom gesture is utilized to determine a desired region and adjust a final zoom level to align the content.

1. A method for interacting with a user interface displaying content on a display of an electronic device, the method comprising:
detecting a zoom gesture to modify a zoom level of the content displayed on the user interface, the zoom gesture comprising two contact points; determining a momentum value for the zoom gesture using a distance traveled by at least one contact point during the zoom gesture and an elapsed time from when the gesture was initiated to when the gesture is terminated; determining a final zoom level based on the determined momentum value of the zoom gesture; and displaying the content on the user interface at the determined final zoom level.
