Abstract: A system and method for determining the relative distances from a plurality of hyperlinks 206 to a cursor 202 when a select button is depressed. The relative distances are compared and the hyperlink corresponding to the shortest distance has its function activated. If the distances are determined to be identical or if the distances are determined to be within a predetermined range of one another, the hyperlinks 206 are not activated. Instead, the user positions the cursor 202 such that it is relatively closer to one of the two or more relatively equidistant hyperlinks 206 and clicks again.

Abstract: The method and system of the present invention may be utilized to enable a blind or visually impaired computer user to graphically select a displayed graphic element within a computer system display. A unique identifiable audible signal is associated with each displayed graphic element. A movable cursor element or pointer is displayed within the computer system display and a composite audible signal is periodically generated in response to the position of the movable cursor element. The composite audible signal preferably includes elements of each identifiable audible signal associated with each displayed graphic element within a predetermined radius of the location of the movable cursor element.

Abstract: A digital display unit receiving a display signal with image encoded at high origin frequencies (e.g., dot clock). A display signal interface samples the display signal during source display time to generate pixel data elements representative of the images encoded in the display signal. The signal is sampled at a sampling frequency equal to origin frequency. The pixel data elements are stored in a buffer at the sampling frequency and retrieved at a slower frequency. Display signals are generated for each horizontal scan line of a digital display screen during a destination display time at this slower frequency. The destination display time is designed to be longer than the source display time, which enables the display signals to be generated from all pixel data elements. The destination display time is longer than the source display time because digital display units do not require the long non-display times present in the display signals.

Abstract: An information display system has a touch panel for selecting an item from a plurality of displayed items by touching. Coordinate differences between each of the coordinates of the plurality of displayed items and the touch position coordinates are calculated. The item having the least calculated coordinate difference is the selected item. Subsequent touchings within a predetermined time and distance are determined to be attempts to correct previous erroneous selections causing probabilities of selecting the previously selected items to be reduced, such as by changing relative calculated coordinate differences to favor selection of other items. Alternatively, a next candidate button can be touched to select the item with the next least coordinate difference.

Abstract: A multi-coloured display unit is described for characters having colour indicator signals. The characters can be displayed in a plurality of colours. Without information of the identify of the characters getting lost, the legibility structure is influenced by the spreading of the colours over the various parts of the text. Initially, such colours are preselected when compiling the text. However, for various implementations this spreading is sub-optimal. Consequently, a transforming device is comprised for realizing and implementing a different colour structure and hence improving the legibility structure depending on the application and the original structure of the colour.

Abstract: An LCD Driver System (10) includes a row decoder (38) for providing command signals to row drivers (50) and a RAM row decoder (64) for controlling a RAM (76) which supplies data to a column driver (88). The row and column drivers (50 and 88) are supplied with power by a power source (58) which can supply either high or low voltages. In normal mode, the power source (58) supplies high voltage and the row driver (50) drives both a dot matrix portion (14) and an icon portion (16) of an LCD display. In an icon mode, a disable signal disables the row decoder (38) and the RAM row decoder (64), enables only the icon row driver (54) of the row drivers (50) and the icon row of the RAM (76) and switches the power source (58) to supply low voltage so as to save power.

Abstract: A method of evaluating pulse width modulation patterns for a spatial light modulator display device. The method makes use of a light difference series function. This series function is obtained by representing on or off times of a display element as a light function. (FIG. 3). Two such light functions can be subtracted to compare two different patterns on the same display element (interframe) or to compare the same pattern on different display elements (intraframe). (FIG. 4). The result of the subtraction is a light difference function (FIG. 5), which can be expressed as a series function. Mathematical expressions using the series function correlate to various optical characteristics.
