  • Patent number: 5940532
    Abstract: A hand-written character recognition apparatus can enhance recognition efficiency by decreasing erroneous recognition caused by habit of user's hand-writing stroke. In a hand-written character recognition apparatus in which user's strokes entered by some suitable means, such as light pen or tablet, are detected, then processed by a character recognition preprocessing, then processed by a recognizing processing for selecting nominated characters based on a standard evaluation point and further, processed by a post-recognizing processing and then supplied to an application device (electronic notebook, electronic dictionary, word processor, personal computer or the like).

  • Patent number: 5907317
    Abstract: A graph displaying device and method whereby when functional expression data for producing graphs and the conditions of displaying the graphs are set, graphs for functional expressions data input in accordance with the conditions are displayed in corresponding colors on a display. First, functional expression data and corresponding color data which designate display colors of the graphs are input in corresponding relationship. In addition, range data which display coordinates and color data designating display colors of coordinates involved in the range data are input together. In response to this operation, the graphs for the input functional expression data are produced with the range data to which the color data are designated, the last-mentioned color data corresponding to color data which correspond to the functional expression data. The produced graphs and the coordinates are displayed in the corresponding designated colors.

  • Patent number: 5535317
    Abstract: A graph display apparatus includes a plurality of functional formulas to be displayed as graphs and their coordinate ranges are stored in a memory by operating numeric .multidot. symbol keys on a key input unit. The plurality of stored formulas are displayed on a display unit by operating a "list" key. When a plurality of arbitrary formulas are designated and a "synthesis" key is operated, the graphs of the designated formulas are calculated and displayed on a single coordinate system in accordance with coordinate ranges of the formula which is designated first. When the plurality of arbitrary formulas are designated and a "division" key is operated, the functional formulas are displayed on different coordinate systems in accordance with corresponding coordinate ranges. When the graphs of a plurality of input formulas are calculated and displayed, the individual graphs can be appropriately synthesized or divided and can be displayed in comparison with each other.

  • Patent number: 5453761
    Abstract: An information processing apparatus (1) has a coordinate data inputting means (31, 32) for sequentially inputting coordinate data by operation of a movable member (6), the coordinate data corresponding to the position of the movable member (6). The movable member is a pen (6), a change of the moving angle of its locus being detected by a detecting means (24) as an angle between the position of the pen (6) and a predetermined base position based on the coordinate data. The base position is displayed on a display (5) as a circular image in the form of a dial on which the pen (6) may be penned down so that a processing means detects the rotating angle of the pen (6) to change a function to be processed. In one arrangement, the circular image acts as a jog control, rotation of the pen (6) causing turning of page numbers.

  • Patent number: 5166666
    Abstract: In an information processing system in which predetermined information is processed on the basis of coordinate data x, y, the coordinate data x, y is inputted through a coordinate inputting means such as a pen and tablet arrangement. Inputted loci are detected by sequentially accepting the coordinate data x, y. The processing mode of the information processing system is switched according to the configuration of the inputted loci. By switching the processing mode in response to the configuration of the inputted loci, the operation mode can be switched. For example, by moving the pen on the tablet in a jumped or reversed direction manner, the processing mode such as storing of a window can be effected.
