Abstract
A presentation authoring tool is used to create presentation data for later projection, to determine a recommended font size for the created presentation data displayed on a display screen of a computer executing the presentation authoring tool. The user interface presents a display screen for receiving input of an expected viewing distance for the later projection of the presentation. The recommended font is determined based upon the expected viewing distance of the later projection having a projected font size viewable by a person, having a certain vision capability, at the expected viewing distance. The expected viewing distance may be a maximum viewing distance or a room depth of a room in which the later projection takes place.
Claims20
A computer-implemented method for enabling a creation of presentation data for later projection, comprising:
- determining a recommended display size for the created presentation data displayed on a display screen of a computer executing a presentation authoring tool, wherein the determining comprises:
- receiving input of an expected viewing distance for the later projection of the presentation data;
- determining the recommended display size based upon the received input of the expected viewing distance of the later projection, wherein the display size has a projected data size viewable by a person who has a certain vision capability, at the expected viewing distance;
- and
- the authoring tool indicating, during preparation of a presentation using the authoring tool, which presentation data is currently smaller than the recommended display size.
A method for displaying presentation data on a display screen of a computer executing a presentation authoring tool for enabling a creation of the presentation data, having a current font size, for later projection, the method comprising:
- receiving input for an expected viewing distance of the later projection having a given projection screen height;
- and
- redisplaying the presentation data using a second font size on the display screen that is representative of an anticipated appearance of the later projection, having a projected font size based upon the current font size, using the given projection screen height, of the presentation data by a person who has a certain vision capability, at the inputted expected viewing distance.
A computer program, on a computer usable storage medium, having program code for enabling a creation of presentation data for later projection, the computer program comprising:
- program code for enabling a determination of a recommended display size for the created presentation data displayed on a display screen of a computer executing a presentation authoring tool, the program code comprising:
- program code for enabling receipt of input of an expected viewing distance for the later projection of the presentation;
- program code for enabling a determination of the recommended display size based upon the received input of the expected viewing distance of the later projection having a projected data size viewable by a person who has a certain vision capability at the expected viewing distance;
- and
- program code for indicating, during a preparation of a presentation using the authoring tool, which presentation data is currently smaller than the recommended display size.
A computer program, on a computer usable medium, having program code for enabling a creation of presentation data, having a current font size, for later projection, the computer program comprising:
- program code for enabling receipt of input for an expected viewing distance of the later projection having a given projection screen height;
- and
- program code for enabling a redisplaying of the presentation data using a second font size on the display screen that is representative of an anticipated appearance of the later projection, having a projected font size based upon the current font size, using the given projection screen height, of the presentation data by a person who has a certain vision capability, at the inputted expected viewing distance.
A computer system having a processor for executing a presentation authoring program, stored in memory, for enabling a creation of presentation data for later projection, the computer system comprising:
- program instructions executable on the processor for determining a recommended display size for the created presentation data displayed on a display screen of the computer, said program instructions comprising:
- instructions for receiving input of an expected viewing distance for the later projection of the presentation;
- instructions for determining the recommended display size based upon the received input of the expected viewing distance of the later projection having a projected data size viewable by a person who has a certain vision capability, at the expected viewing distance;
- and
- instructions for indicating, during a preparation of a presentation, which presentation data is currently smaller than the recommended display size.
A computer system having a processor for executing a presentation authoring tool, stored in memory, for enabling a creation of presentation data, having a current font size, for later projection, the computer system comprising:
- program instructions for receiving input for an expected viewing distance of the later projection having a given projection screen height;
- and
- program instructions for redisplaying the presentation data, on a display screen of the computer, using a second font size on the display screen that is representative of an anticipated appearance of the later projection, having a projected font size based upon the current font size, using the given projection screen height of the presentation data by a person who has a certain vision capability, at the received expected viewing distance.
