  • Patent number: 6141014
    Abstract: A map display apparatus for displaying perspective image of a map. The apparatus includes an image display device for displaying the perspective image of the map and a map data storage device for storing map data. Map drawing means is included for preparing map drawing data using the map data and for displaying a perspective image of the map on the display device on the basis of the drawing data. The map drawing means transforms coordinate data of a map into data suitable for display of the perspective image of the map. The data transformation is accomplished by perspectively projecting the coordinate data onto a predetermined projection plane with a view point at a desired position. The projection plane is determined on the basis of two predetermined points in the map data, such as the current position of a vehicle and the destination, so that drawing positions of the two points after the perspectively projecting operation are coincident with predetermined positions.

  • Patent number: 5917475
    Abstract: A display device has a touch pad and a display lamintated together to form a screen, That screen is connected to a controller which processes signals generated by physical contact with the touch pad and activates the display to display e.g. characters input by a stylus to the touch pad. The display device is connected to an external device (e.g. a computer) and video signals from the external device are received via a video input and may be displayed on the display. Also the controller can transmit to the external device via an output. Thus, the display can simultaneously display information from the external device and information input to the touch pad. If the controller is arranged to carry out character recognition, the display device may then act as a handwriting input device, with the handwritten information being incorporated with information in the external device and displayed.

  • Patent number: 5841901
    Abstract: A pattern recognition system having a plurality of dictionaries, wherein handwritten input information is compared with patterns contained in the plurality of dictionaries so as to deliver a similar one of the patterns as a recognized result; The system comprises a controller which selects one pattern as a final recognized result from among recognized results based on the plurality of dictionaries, so as to deliver the selected pattern as its output. The controller evaluates summations of values previously set for respective candidate levels in the recognized results, for individual candidate patterns which exist in the recognized results based on the plurality of dictionaries, and it selects the pattern of the final recognized result on the basis of the summations. Thus, the recognized result most suited to a user is automatically derived from among the recognized results based on the plurality of dictionaries.

  • Patent number: 4860372
    Abstract: A plurality of handwritten character input buffers are provided to form a circular buffer by connecting both end character input buffers. The circular buffer is provided with a cursor pointer for indicating the position of the buffer where a recognized character is loaded. Every time a character is recognized, its character code is loaded at the buffer indicated by the content of the cursor pointer and thereafter, the content of the cursor pointer is incremented by 1. At least an input buffer after the buffer indicated by the content of the cursor pointer, where a handwritten character is next written, is cleared. Then, the content of the character input buffer is displayed on a display.

  • Patent number: 4718103
    Abstract: A handwritten pattern approximated to a series of polygonal lines consisting of segments is compared with a candidate pattern selected from dictionary patterns stored in the memory, basing on the angular variation between adjacent segments of both patterns. If the difference between angular variations of adjoining segments of both patterns is outside of a certain range, it is tested whether the difference between an angular variation across three or more consecutive segments and the above reference angular variation is within the range.

  • Patent number: 4680804
    Abstract: A hand-written character/graphic is recognized in a character recognition mode or a graphic recognition mode designated in accordance with stroke information supplied from a tablet input device which samples the hand-written character/graphic and converts it to the stroke information. The recognition mode is automatically designated by comparing a longer one of projection lengths on x-axis and y-axis of stroke coordinates with a predetermined threshold for a hand-written character input.

  • Patent number: 4653107
    Abstract: Coordinates of a handwritten pattern drawn on a tablet are sequentially sampled by a pattern recognition unit to prepare pattern coordinate data. Based on an area encircled by segments created by the sampled pattern coordinate data of one stroke and a line connecting a start point and an end point of the one-stroke coordinate data, the sampled pattern coordinate data of the one stroke is converted to a straight line and/or curved line segments. The converted segments are quantized and normalized. The segments of the normalized input pattern are rearranged so that the input pattern is drawn in a predetermined sequence. Differences between direction angles for the rearranged segments are calculated. Those differences are compared with differences of the direction angles of the dictionary patterns read from a memory to calculate a difference therebetween. The matching of the input pattern and the dictionary pattern is determined in accordance with the difference.
