Abstract
A system for conveying location of an object by varying a characteristic such as size, color, or intensity of an icon located in a two dimensional display. In the illustrative embodiment, the invention represents aircraft altitude by the size of an icon. Each aircraft position and heading is plotted as location and orientation of the icon in two-dimensional space, the axes of which represent latitude and longitude. The size of the icon is selected from a limited number of discriminably different sizes to represent the aircraft altitude. Each size represents a distinct altitude range.
Claims13
A system for conveying location of an object comprising:
- first means for receiving location information regarding said object, said location information including a first coordinate x, a second coordinate y, and a third coordinate z;
- second means for correlating said first and second coordinates (x,y) with a location of an icon in two-dimensional space in an electro-optical display;
- and
- third means for correlating said third coordinate z with a size of said icon.
A system for conveying location of an object comprising:
- first means for receiving location information regarding said object, said location information including a first coordinate x, a second coordinate y, and a third coordinate z;
- second means for correlating said first and second coordinates (x,y) with a location of an icon in an electro-optical display;
- and
- third means for correlating said third coordinate z with a color or grayscale value of said icon.
A system for conveying location of an object comprising:
- first means for receiving location information regarding said object, said location information including a first coordinate x, a second coordinate y, and a third coordinate z;
- second means for correlating said first and second coordinates (x,y) with a location of an icon in an electro-optical display;
- and
- third means for correlating said third coordinate z with an intensity (i.e., contrast value) of said icon.
A system for conveying location of an object comprising:
- first means for receiving location information regarding said object, said location information including a first coordinate x, a second coordinate y, and a third coordinate z;
- second means for correlating said first and second coordinates (x,y) with a location of an icon in an electro-optical display;
- and
- third means for correlating said third coordinate z with a shape of said icon.
A system for conveying aircraft altitude to a human observer comprising:
- a receiver for receiving latitude, longitude, and altitude information;
- a microprocessor;
- a memory device;
- a display;
- and
- a program for converting said altitude to an icon size, and placing an icon of said icon size at coordinates corresponding to said latitude and longitude in said display.
A method for conveying location of an object including the steps of:
- receiving location information regarding said object, said location information including a first coordinate x, a second coordinate y, and a third coordinate z;
- correlating said first and second coordinates (x,y) with a location of an icon in an electro-optical display;
- and
- correlating said third coordinate z with a size of said icon.
