Abstract

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.

Claims

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.

2. A method as recited in claim 1 further comprising:

closing the path if contact with the screen is terminated, thereby not displaying any content from the table layer.

3. A method as recited in claim 1 further comprising:

creating a particle layer, wherein the particle layer is used to visually block content in the table layer on the screen of the device; and

creating a ghost layer.

4. A method as recited in claim 1 wherein the clip from the table layer represents content from the table layer pasted into the path on the ghost layer, wherein the clip is in the shape of a circle.

5. A method as recited in claim 1 wherein detecting whether there is movement of the contact point further comprises:

determining what new content to paste from the table layer to the path based on contact point movement.

6. A method as recited in claim 1 wherein re-drawing the ghost layer based on contact point movement further comprises:

re-pasting content from the table layer to the path upon detection of contact point movement.

7. A method as recited in claim 1 further comprising:

detecting that a user has set a hide messages feature on the mobile device.

8. A method as recited in claim 3 wherein the particle layer is opaque and covers content shown in the table layer and wherein the ghost layer is transparent and shows the path only when there is contact on the screen.

9. A system for hiding messages on a screen of a mobile device using a ghost mode setting, the system comprising:

a memory storing software for implementing the ghost mode setting; and

a processor configured to;

enable a ghost layer on the device;

detect contact on the device screen;

create a path using a contact point and pre-determined radius, said path shown on the ghost layer;

determine content to clip from a table layer to the path, wherein the table layer displays content in a conventional manner;

re-draw the ghost layer on the device, wherein the path is shown on the ghost layer and content is shown within confines of the path;

detect whether there is movement of the contact point; and

re-draw the ghost layer based on contact point movement.

10. A system as recited in claim 9 wherein the processor is further configured to close the path if contact with the screen is terminated, thereby not displaying any content from the table layer.

11. A system as recited in claim 9 wherein the processor is further configured to create a particle layer, wherein the particle layer is used to visually block content in the table layer on the screen of the device and configured to create a ghost layer.

12. A system as recited in claim 9 wherein the clip from the table layer represents content from the table layer pasted into the path on the ghost layer, wherein the clip is in the shape of a circle.

13. A system as recited in claim 9 wherein the processor, configured to detect whether there is movement of the contact point, is further configured to determine what new content to paste from the table layer to the path based on contact point movement.

14. A system as recited in claim 9 wherein the processor, configured to re-draw the ghost layer based on contact point movement, is further configured to re-paste content from the table layer to the path upon detection of contact point movement.

15. A system as recited in claim 9 wherein the processor is further configured to detect that a user has set a hide messages feature on the mobile device.

16. A system as recited in claim 11 wherein the particle layer is opaque and covers content shown in the table layer and wherein the ghost layer is transparent and shows the path only when there is contact on the screen.
