Abstract

The systems and methods of the client agent describe herein provides a solution to obtaining, recognizing and taking an action on text displayed by an application that is performed in a non-intrusive and application agnostic manner. In response to detecting idle activity of a cursor on the screen, the client agent captures a portion of the screen relative to the position of the cursor. The portion of the screen may include a textual element having text, such as a telephone number or other contact information. The client agent calculates a desired or predetermined scanning area based on the default fonts and screen resolution as well as the cursor position. The client agent performs optical character recognition on the captured image to determine any recognized text. By performing pattern matching on the recognized text, the client agent determines if the text has a format or content matching a desired pattern, such as phone number. In response to determining the recognized text corresponds to a desired pattern, the client agent displays a user interface element on the screen near the recognized text. The user interface element may be displayed as an overlay or superimposed to the textual element such that it seamlessly appears integrated with the application. The user interface element is selectable to take an action associated with the recognized text.

Claims

(b) recognizing, by the client agent, via optical character recognition text of the textual element in the captured image;

(c) determining, by the client agent, the recognized text comprises contact information; and

(d) displaying, by the client agent in response to the determination, a user interface element near the textual element on the screen selectable to initiate a telecommunication session based on the contact information.

2. The method of claim 1, wherein step (a) comprises capturing, by the client agent, the image in response to detecting the cursor on the screen is idle for a predetermined length of time.

3. The method of claim 2, wherein the predetermined length of time is between 400 ms and 600 ms.

4. The method of claim 1, wherein step (d) comprises displaying, by the client agent, a window near one of the cursor or textual element on the screen, the window providing the selectable user interface element to initiate the telecommunication session.

5. The method of claim 1, comprising displaying, by the client agent, the selectable user interface element superimposed over the portion of the screen.

6. The method of claim 1, comprising displaying, by the client agent, the user interface element as a selectable icon.

7. The method of claim 1, comprising displaying, by the client agent, the selectable user interface element while the cursor is idle.

8. The method of claim 1, wherein step (a) comprises capturing, by the client agent, the image of the portion of the screen as a bitmap.

9. The method of claim 1, comprising identifying, by the contact information, one of a name of a person, a name of a company, or a telephone number.

10. The method of claim 1, comprising selecting, by a user of the client, the selectable user interface element to initiate the telecommunication session.

11. The method of claim 10, comprising transmitting, by the client agent, information to a gateway device to establish the telecommunication session on behalf of the client.

12. The method of claim 11, comprising establishing, by the gateway device, the telecommunications session via a telephony application programming interface.

13. The method of claim 10, comprising establishing, by the client agent, the telecommunications session via a telephony application programming interface.

14. The method of claim 1, wherein step (c) comprising performing, by the client agent, pattern matching on the recognized text.

15. The method of claim 1, comprising performing, by the client agent, step (a) through step (d) in a period of time not exceeding 1 second.

16. The method of claim 1, comprising identifying, by the client agent, the portion of the screen as a rectangle determined based on one or more of the following:

default font pitch, screen resolution width, screen resolution height, x-coordinate of the position of the cursor and y-coordinate of the position of the cursor.

17. The method of claim 1, wherein step (a) comprises capturing, by the client agent, the image of the portion of the screen relative to a position of a cursor.

18. A system for determining a user interface is displaying a textual element identifying contact information and automatically providing in response to the determination a selectable user interface element near the textual element to initiate a telecommunication session based on the contact information, the system comprising:

a client agent executing on a client, the client agent comprising a cursor activity detector to detect activity of a cursor on a screen;

a screen capture mechanism capturing, in response to the cursor activity detector, an image of a portion of the screen displaying a textual element identifying contact information;

an optical character recognizer recognizing text of the textual element in the captured image;

a pattern matching engine determining the recognized text comprises contact information; and

wherein the client agent displays in response to the determination a user interface element near the textual element on the screen selectable to initiate a telecommunication session based on the contact information.

19. The system of claim 18, wherein the screen capture mechanism captures the image in response to detecting the cursor on the screen is idle for a predetermined length of time.

20. The system of claim 19, wherein the predetermined length of time is between 400 ms and 600 ms.

21. The system of claim 18, wherein the client agent displays a window near one of the cursor or textual element on the screen, the window providing the selectable user interface element to initiate the telecommunication session.

22. The system of claim 18, wherein the client agent displays the selectable user interface element superimposed over the portion of the screen.

23. The system of claim 18, wherein the client agent displays the user interface element as a selectable icon.

24. The system of claim 18, wherein the client agent displays the selectable user interface element while the cursor is idle.

25. The system of claim 18, wherein the screen capturing mechanism captures the image of the portion of the screen as a bitmap.

26. The system of claim 18, wherein the contact information comprises one of a name of a person, a name of a company or a telephone number.
