Definitions

  • This invention relates to computers, and more particular, to a data input system for pen-based portable computers.
  • FIGURE 1 An example of a prior art pen-based hand-held computer is shown in FIGURE 1.
  • the illustrated hand-held computer 1 is typically about 4 inches by 6.5 inches, with the majority of one surface comprising a touch-sensitive display screen 2.
  • the display screen 2 is typically a liquid crystal display (LCD) having a resolution of 240x320 pixels or greater (although larger or smaller pixel arrays could be used).
  • LCD liquid crystal display
  • Various technologies can be used to sense the location of a pen or stylus 3 touched against the surface of the LCD screen 2 to indicate to the computer's operating system the X-Y coordinates of the touch.
  • Such a computer may be provided with an option slot 4, which may be, for example, a PCMCIA-compliant adapter slot.
  • buttons 5 may be provided to control different functions, and/or to turn power on or off to the unit.
  • buttons or icons 6 may be provided, in known fashion, to indicate such functions as, for example, word processing or a delete ("trash can") function.
  • Computer-generated information is typically shown on the display screen 2 as ASCII characters 7. Data input is typically received and/or displayed in specific fields 8.
  • a common characteristic of such pen-based computers is the use of character recognition software to convert "ink” characters input by a user into computer readable text, such as ASCII characters.
  • "Ink” comprises a series or trail of pixels changed (e.g., darkened or lightened) as a pen 3 is moved across the display screen 2 by a user, thus mimicking the application of real ink to paper.
  • One such character recognition system is described in U.S. Patent No. 5,125,039, entitled “Object Recognition System", by the inventor of the present invention.
  • the computer applies special algorithms to recognize each character as an ASCII character, and replaces the ink representation of the character drawn by the user with a standardized ASCII representation of that character.
  • unrecognized ink is very fast and easy to input, it is less useful than ink that has been recognized as text. Because unrecognized graphical ink input is unstructured and has no meaning or associations to the computer, the computer cannot perform searches on or use ink data types in intelligent ways. Thus, later use of such input is severely restricted. To overcome this significant limitation, some computer designs allow the user to assign key words to a block of ink input. This requires extra steps by the user in anticipation of future needs, and has limited utility.
  • a hand-held comput ⁇ er might have a display measuring only about 2Vz by 3 inches.
  • the present invention provides such a method.
  • the present invention comprises a data input system ideally suited for pen-based portable computers having a limited writing area.
  • a hand-held computer using the invention permits a user to select a pre-defined data display field, whereupon an enlarged ink input field is displayed to the user.
  • the computer accepts ink input from the user into the enlarged ink input field.
  • the enlarged ink input field may be scrollable, automatically or manually, to present additional "blank" writing area to the user.
  • the user has the option of selecting whether the ink input is to be saved as an ink data type, or recognized and converted to text characters. If the user accepts the ink input as an ink data type, then the computer shrinks (reduces) the ink input to fit within the original data display field and displays the reduced ink input in the original data display field.
  • the ink is reduced sufficiently (typically 2:1) to fit within the width of the original data display field, and the height of the data display field is automatically resized to accommodate all of the ink that was entered in the enlarged ink input field.
  • the original data display field may indicate, by means of a scroll icon or similar means, that the field contains additional non-displayed ink input. Activating the indicator allows the user to scroll the reduced ink input in the data display field.
  • the computer recognizes the ink input as text characters, and displays the text characters in the input field.
  • the user closes the enlarged ink input field, and the recognized text is displayed in the data display field.
  • reduced ink input may be processed at a later time to recognize the ink input as text characters.
  • the invention allows a user to enter data quickly into a larger writing field but display the data in a smaller viewing field.
  • the ink data is useful to the user and the computer because the data is entered into defined input fields, and thus a context is automatically associated with the data.
  • the invention permits a user to enter data as rapidly as the user can write, and convert the data to text characters at a later time.

  • the scheduling application shows six data display fields 11 opposite six corresponding labels for hours of the day, ranging from 10:00 a.m. to 3:00 p.m.
  • the label field 10 at the top of the screen shows the day of week and date, and a "close application" icon 13.
  • the data display field for the time "12:00” has an ASCII text entry of "LUNCH WITH BOB", previously entered by a user.
  • the image shown in FIGURE 2 is approximately 3" wide by 5" high. It should be clear that it would be difficult for a user to accurately input ink directly into any of the data display fields 11 because of the small size of such fields and the limitations of displays and digitizers, as mentioned previously.
  • a user selects a data display field 11 by touching the field with a pen or stylus 3. For example, if the user wishes to make an entry in the data display field 11 a opposite the 10:00 label 10, the user would touch a pen anywhere within that data display field 11. Sensing the location of a touch on the display screen 2 by the pen 3 and associating the touch with a data field or window are well-known in the art.
  • FIGURE 3A is a front plan view of the display screen of the computer of FIGURE 2, showing a first embodiment of an enlarged ink input field or window 14. Referring to FIGURE 3A, a pen touch on the data display field 11 a corresponding to the 10:00 label 10a causes the enlarged ink input field 14 to be displayed on the display screen 2. Generation of such fields or windows is well known in the art.
  • FIGURE 3A is a front plan view of the display screen of the computer of FIGURE 2, showing an enlarged ink input field 14 that encompass ⁇ es only the lower portion of the display screen 2, with some or all of the data display fields 11 still being shown.

  • other labels for such soft keys, and other functions could be provided.
  • the "INK' mode 12a icon and 'TEXT' mode 12b icon have been provided to allow a user to select or switch between the type of input mode desired.
  • the "INK' mode all input is accepted as ink.
  • the user may edit the input as desired.
  • the user presses the "OK' icon 12d to accept the ink input for display in the selected data display field 11a.

Note that the user may save both recognized ink input and unrecognized ink input in a single data display field 11 , and can switch between the "INK' mode and the 'TEXT' mode as desired by selecting the respective icons 12a, 12b.
  • the user has entered the phrase "MEETING WITH JEFF AT OFFICE". If the user had selected the "INK' mode icon 12a, all input would be in shown in the enlarged ink input field 14 as ink. If the user had selected the 'TEXT' mode icon 12b, all input would be recognized as the user writes. In either event, if the user uses the pen 3 to select the "OK' icon 12d, the input would be saved to the selected data display field 11 a.

  • the ink input has been reduced in size to fit within the previously selected data display field 11 a. Size reduction of ink input can be accomplished in any number of ways known in the prior art.
  • the ink input is represented as vectors.
  • the length of each vector stroke comprising each character can be mathematically shortened by a desired amount or percentage, and reduced size characters can then be constructed from the shortened vector representation, in known fashion.

  • the size reduction can be user-settable or automatically scaled.
  • the size reduction for the ink input is limited to an amount that makes the input readable when displayed in the selected data display field 11 a.
  • the longest vertical dimension for user input in the enlarged ink input field 14 can be determined as the number of pixels from the top-most pixel to the bottom-most pixel of the ink input. That vertical length is then used to scale the ink input to fit within the selected data display field 11 a. For example, if the vertical length is found to be 200 pixels, and the vertical dimension of the selected data display field 11 a is 50 pixels, a 4:1 scaling ratio can be used to reduce the size of the original ink input. Alternatively, the horizontal axis, or both the vertical and horizontal axes, can be used to determine the scaling factor.

Abstract

Système (3) de saisie de données idéal pour ordinateurs portatifs (1) à tablette électronique ayant une surface limitée d'écriture. Un utilisateur sélectionne un champ pré-défini (11) d'affichage de données, et à ce moment un champ élargi (14) d'écriture est affiché. L'utilisateur peut choisir si les inscriptions manuscrites saisies sont à sauvegarder sous forme de données manuscrites, ou si elles doivent être reconnues et converties en caractères de texte. Si l'utilisateur accepte que les inscriptions manuscrites restent sous forme de données manuscrites, les inscriptions sont alors réduites pour pouvoir entrer dans le champ original d'affichage de données, et le champ (1) d'affichage de données est automatiquement redimensionné pour contenir les inscriptions saisies dans le champ élargi (14) d'inscription. Si l'utilisateur accepte que les inscriptions soient reconnues, alors l'ordinateur reconnaît les inscriptions sous forme de caractères de texte et affiche les caractères de texte dans le champ (11) d'affichage de données. Les inscriptions réduites peuvent être traitées ultérieurement afin d'être reconnues sous forme de caractères de texte.
