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 method for enabling a creation of presentation data for later projection, comprising:
- determining a recommended size for the created presentation data displayed on a display screen of a computer executing a presentation authoring tool, comprising:
- receiving input of an expected viewing distance for the later projection of the presentation data;
- determining the recommended size based upon the expected viewing distance of the later projection having a projected data size viewable by a person, having a certain vision capability, at the expected viewing distance;
- and.
- indicating, during preparation of a presentation using the authoring tool, presentation data that is smaller than the recommended size.
A method for displaying presentation data on a display screen of a computer executing a presentation authoring tool having means for enabling a creation of the presentation data, having a current font size, for later projection, 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, having a certain vision capability, at the 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 size for the created presentation data displayed on a display screen of a computer executing a presentation authoring tool, 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 size based upon the expected viewing distance of the later projection having a projected data size viewable by a person, having a certain vision capability, at the expected viewing distance;
- and
- program code for indicating, during a preparation of a presentation using the authoring tool, presentation data that is smaller than the recommended 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, having a certain vision capability, at the 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:
- means for determining a recommended size for the created presentation data displayed on a display screen of the computer, comprising:
- means for receiving input of an expected viewing distance for the later projection of the presentation;
- means for determining the recommended size based upon the expected viewing distance of the later projection having a projected data size viewable by a person, having a certain vision capability, at the expected viewing distance;
- and
- means for indicating, during a preparation of a presentation, that presentation data is smaller than the recommended 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:
- means for receiving input for an expected viewing distance of the later projection having a given projection screen height;
- and
- means 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, having a certain vision capability, at the expected viewing distance.
