US 2008/0189652 A1 · SYSTEM AND COMPUTER PROGRAM FOR CONTROLLING SCREEN FOCUS FOR FILES AND APPLICATIONS DURING PRESENTATIONS

Abstract

A system and computer program for controlling screen focus for files and applications during presentations provides for protection of information in a computer-generated presentation setting and prevention of interruption of a presentation by unwanted computer activity. A list is built of applications and files for which screen access is permitted during the presentation. Upon an indication that the presentation is active, when an application or file is about to obtain screen focus, the list is checked to determine whether access is permitted for the file or application. If the application or file is should not have the focus, execution of an application or opening of a file is blocked, or screen focus is denied to windows generated in conjunction with application or file. The indication that the presentation is active may be the connection of a particular display type (e.g., a projector) or the use of a certain display port.

Dependent claims

A computer system including a memory for storing program instructions and data, and a processor for executing said program instructions, and wherein said program instructions comprise program instructions for:

building a list of executable or document files for which corresponding windows are permitted to have screen focus during said computer-generated presentation;
first determining whether or not a computer-generated presentation is active;
in response to determining that said computer-generated presentation is active, second determining whether or not a particular executable or document file has a corresponding window that is about to obtain a focus of said computer screen;
in response to determining that said corresponding window is about to obtain said focus, third determining whether or not said particular executable or document file is in said list of files;
and
in response to determining that said particular executable or document file is not in said list of files, preventing said corresponding window from obtaining said focus.

3 more elements

A computer program product comprising computer-readable storage media encoding program instructions for execution on a general-purpose computer system, wherein said program instructions comprise program instructions for:

building a list of executable or document files for which corresponding windows are permitted to have screen focus during said computer-generated presentation;
first determining whether or not a computer-generated presentation is active;
in response to determining that said computer-generated presentation is active, second determining whether or not a particular executable or document file has a corresponding window that is about to obtain a focus of said computer screen;
in response to determining that said corresponding window is about to obtain said focus, third determining whether or not said particular executable or document file is in said list of files;
and
in response to determining that said particular executable or document file is not in said list of files, preventing said corresponding window from obtaining said focus.
