PREVENTING VISUAL OBSERVATION OF CONTENT ON A MOBILE DEVICE BY HIDING CONTENT

摘要

Users can hide content normally displayed on a mobile device screen and read or view content by touching the screen and creating a path, for example, in the shape of a circle, in which a portion of the content can be viewed. The content is hidden by a particle layer. A “hole” into the particle layer and a ghost layer is used to view content normally shown in a table view. Embodiments of the present invention allow a user to view partial content in a table (message) view, such as part of a text message, through a pre-defined area, such as a circle, square or any other shape the designer chooses while covering the other content on the screen.

主权项

1. A method of hiding content displayed on a screen, the method comprising:
enabling a ghost layer on the device; detecting contact on the screen of the device; creating a path using a contact point and pre-determined radius, said path on the ghost layer; determining content to clip from a table layer to the path, wherein the table layer displays content in a conventional manner; re-drawing the ghost layer on the device, wherein the path is shown on the ghost layer and content is shown within confines of the path; detecting whether there is movement of the contact point; and re-drawing the ghost layer based on contact point movement.
