`Aportable information gathering apparatus and information
`managing method in the same make it possible to capture
`information entered through an input/dismay tablet’ image
`information entered through an image input device and
`voice information entered through a voice input device, and
`other type of information for individual pageS, each corre-
`sponding to all information displayed at one time on a
`screen In response to an instruction given by a user of the
`portable information gathering apparatus, an attach-to-page
`icon setting unit attaches icons to desired pages to manage
`the page information in units of pages. Several of these icons
`are: an icon for managing the information captured in
`respective pages by time-related data such as date and time;
`an icon for specifying a particular page; an icon serving as
`a memo guide; and an icon for managing the information
`captured in the respective pages by the type of information.

`PORTABLE INFORMATION GATHERING
`APPARATUS AND INFORMATION
`MANAGEMENT METHOD
`
`BACKGROUND OF THE INVENTION
`
`1. Field of the Invention
`
`invention relates to portable information
`The present
`gathering equipment such as a pen computer and, more
`particularly,
`to a portable information gather apparatus
`which can function to manage captured information on a
`page basis, and an information management method by the
`apparatus.
`2. Description of the Related Art
`In recent years, pen computers and other similar devices
`have been coming into widespread use as portable informa-
`tion gathering equipment. There are being developed pen
`computers which can not only record information written on
`a tablet-screen with an input pen, but can also capture
`images and spoken statements. There are increasing tenden-
`cies to enhance the multifunctional features of such pen
`computers for greater convenience.
`FIG. 21 is a schematic block-diagram showing conven-
`tional portable information gathering equipment constructed
`to perform the function of recording information written on
`a tablet screen with an input pen and also the function of
`capturing images and voice inputs. This portable informa-
`tion gathering equipment is constituted primarily by a CPU
`1, a ROM 2 in which processing programs and the like are
`stored, a data memory 3, a tablet 6 which combines a
`digitizer 4 and an LCD 5 into one piece, an image input
`device 7, a voice input device 8, a voice output device 9, an
`information gathering menu selector 10, and a system bus 11
`for connecting these components to the CPU 1.
`Judging from the illustrated configuration, this type of
`conventional portable information gathering equipment is
`designed to capture image and voice information in addition
`to the pen input information which is known as “ink infor-
`mation” captured through the tablet 6.
`In the conventional portable information gathering
`equipment, however, whenever entering information, a
`menu selection has to be performed through the information
`gathering menu selector 11 to properly set the mode in
`accordance with the type of information to be captured
`before entering the information. For instance, to enter an
`image and then characters, the mode must be set first for
`image input
`to capture an image,
`then the mode must
`changed to character input to take in characters.
`For the portable information gathering equipment to be
`user-friendly, all the different types of captured information,
`namely, the image information, the voice information, and
`the ink information, should be handled as a collection on a
`page basis (hereinafter referred to as “page data”). For
`example, to record the information about a certain product
`in terms of one-page information, it would be convenient to
`enter the image of the product and add the description of the
`image in terms of voice information or ink information
`entered using a pen, thus handling all the image, voice, and
`ink information as a piece of page data, that is, handling
`them in units of pages.
`is desirable that multimedia
`it
`More specifically,
`information,
`including image information, voice
`information, and ink information, captured by a user arbi-
`trarily be stored automatically in a storing means as page
`data, i.e. a single piece of collective data on a page basis

`without the need for operation by the user so that the user is
`not even aware of the processing.
`This type of conventional portable information gathering
`equipment, however, has not been designed to automatically
`handle all of the image information, voice information, and
`ink information as page data for each page without the need
`for the performance of operations by the user of the equip-
`ment.
`
`Furthermore, this type of information gathering equip-
`ment handles a wide variety of information and the volume
`may be as large as over 100 pages. Therefore, the user is
`required to manage entered information by alarm setting or
`some other method according to the type of information
`when reading a particular piece of information from among
`the information which has been stored, or reading all related
`information, or if entered information has any time limit.
`In this type of conventional portable information gather-
`ing equipment such as a pen computer,
`it is possible to
`manage the captured information to a certain extent by
`setting an alarm or the like by writing date, time, contents of
`information, etc. according to a predetermined format.
`However, if such equipment allows information including
`pen input, image, and voice information to be entered as
`desired while it does not have any specified format, then it
`would have to have a function for managing such informa-
`tion whenever it is entered.
`
`SUMMARY OF THE INVENTION
`
`Accordingly, it is an object of the present invention to
`provide a portable information gathering apparatus and an
`information management method in the same which obviate
`the need of setting mode according to information to be
`captured whether it is image information, voice information,
`or ink information, which enable a user thereof to enter any
`type of information as he or she desires, and which permit
`efficient management of information by efficiently retrieving
`desired information among entered information, by associ-
`ating the information on different pages, or by providing
`information with alarms.
`
`To this end, according to one aspect of the present
`invention, there is provided a portable multimedia informa-
`tion gathering apparatus for gathering and displaying
`entered information and for also storing the gathered
`information, which is equipped at least with: information
`input means for entering information; page adding icon
`setting means for pasting an icon corresponding to the
`information, which has been entered for each page equiva-
`lent to one screen by the information input means,
`to a
`specified page; and data storing means wherein the infor-
`mation entered through the information input means and the
`information regarding the icon pasted to the specified page
`are written at a specified address.
`The information to be entered is at least one of: informa-
`
`tion entered through the input/display tablet for capturing
`information when the screen thereof is touched and also for
`
`image information
`displaying the captured information;
`entered through image input means, and voice information,
`or spoken statements, entered through voice input means.
`The icon pasted to the specified page is at least one of: an
`icon for managing the information captured in respective
`pages by time-related data such as date and time; an icon for
`specifying a particular page; an icon serving as a memoran-
`dum guide; and an icon for managing the information
`captured in the respective pages by the type of information.
`The information regarding the icon pasted on the specified
`page written to the data storing means is the information
`19
`
`19
`
`
`
`US 6,710,791 B1
`
`3
`indicating the type of icon and positional information indi-
`cating the position where the icon is pasted. The icon
`information for the icon for managing information captured
`in the respective pages by the time-related data such as date
`and time is the time-related information including date and
`time as well as the information indicating the type of icon
`and the positional information.
`With this arrangement, an icon corresponding to infor-
`mation captured on each page can be pasted to captured
`information, and these different types of icons are pasted on
`a page basis as desired,
`thus enabling the pages to be
`managed by the types of icons pasted on the pages. This
`makes it possible to set such functions as alarm, To Do,
`quick call, and automatic erase in units of pages, to permit
`a background stamp such as a telephone memorandum to be
`pasted on each page, and to classify page information by
`type by using the icons. These features are extremely
`convenient for managing and retrieving data which has been
`entered.
`
`invention,
`According to another aspect of the present
`there is provided an information managing method in a
`portable multimedia information gathering apparatus which
`gathers and displays entered information and also stores the
`gathered information, whereby an icon, which corresponds
`to the information captured for each page equivalent to one
`screen by information input means, can be pasted to a
`specified page, and when the icon has been pasted in a
`predetermined position on the page, the information entered
`through the information input means together with the
`information regarding the pasted icon are written at a
`specified address in data storing means, thus implementing
`information management based on the written information
`regarding the icon.
`The information to be entered is at
`
`least one of the
`
`information captured through the input/display tablet which
`captures information when the screen thereof is touched, the
`image information captured through the image input means,
`and the voice information captured through the voice input
`means.
`
`The icon pasted on a specified page is at least one of the
`following icons: an icon for managing information captured
`into the pages by time-related data such as date and time; an
`icon for specifying a particular page; an icon serving as a
`memorandum guide; and an icon for managing information
`captured into the pages by the type of information.
`The information regarding the icon pasted on the specified
`page which is written to the data storing means is the
`information indicating the type of icon and the positional
`information indicating the position where the icon is pasted.
`The information regarding the icon, if the icon is the one for
`managing the information captured into the pages by time-
`related data such as date and time, is the information related
`to time including date and time.
`Use of the method described above allows icons to be
`
`pasted according to the information captured into the pages
`and also the pages to be managed by the type of icon by
`pasting different types of icons as desired in units of pages.
`This makes it possible to set such functions as alarm, To Do,
`quick call, and automatic erase in units of pages, to permit
`a background stamp such as a telephone memorandum to be
`pasted on each page, and to classify page information by
`type by using the icons. These features are extremely
`convenient for managing and retrieving data which has been
`entered. Applying the method in accordance with the present
`invention to a pen computer or the like turns it into an
`extremely user-friendly pen computer.

`verter 27 for converting the voice signals to digital signals;
`an input/display tablet 28 which combines a digitizer 281
`and a liquid crystal display (LCD) 282 into one unit and
`which captures information including characters and line
`drawings and which also displays the captured information;
`an LCD circuit controller 29; a digital-to-analog converter
`30 for converting the voice signals to analog signals when
`outputting voice signals; an amplifier 31; a speaker 32; a
`flash memory 33 serving as a data storing means for storing
`data captured by a user (the data to be stored in the flash
`memory and the storing areas thereof will be described in
`detail later); a RAM 34 used as a work memory when
`implementing various types of processing in the pen com-
`puter; a real time clock 35 which indicates the current time
`and provides time information and date information; a
`power switch 36; page feed buttons which are comprised of
`a next page button 37 and a previous page button 38; a
`camera button 39; a button signal processor 41 which detects
`the ON/OFF state of a button such as a voice input button 40
`and issues signals corresponding to the ON/OFF state; an
`external equipment connecting device 42 for the transfer of
`information between itself and external information process-
`ing equipment such as a personal computer; a system bus 43
`for interconnecting the individual sections and component
`units; and an attach-to-page icon setting processor 44 which
`carries out various types of processing on attach-to-page
`icons which are pasted to respective pages so as to manage
`information captured into the pages by time-related data
`such as date and time or classify the information by type or
`to indicate a background of a memorandum, etc. The attach-
`to-page icons, which are to be attached to pages, are put on
`respective pages as if they were stamped thereon; therefore,
`the icons will be hereinafter referred to as “stamps” which
`will be described in detail later.
`
`The external equipment connecting device 42 is con-
`structed primarily by: a serial controller 421; an RSZ32C
`port 422 used as an interface for connection to external
`information processing equipment such as a personal com-
`puter; an infrared receiver/transmitter 423 for performing
`optical communication with information processing equip-
`ment such as a personal computer; a light emitting diode
`(LED) 424; and a photo diode 425.
`FIG. 2 shows an external view of the pen computer in
`accordance with the present invention; components identical
`to those shown in FIG. 1 are assigned the same reference
`numerals as in FIG. 1. Among the constituent elements
`shown in FIG. 1, those that appear in the external view of
`FIG. 2 include the CCD camera 23 (more precisely a lens
`23a of the CCD camera 23), the camera button 39, the tablet
`28,
`the microphone 25,
`the speaker 32,
`the voice input
`button 40, the next page button 37, the previous page button
`38, and the power switch 36. Provided on the screen of the
`tablet 28 is a function menu selector 70. An input pen 51 is
`used to draw characters or lines on the screen of the tablet
`
`28 and to point at icons.
`As illustrated in FIG. 3, the function menu selector 70
`pre-displays icons indicating menus, including a “find” icon

`71, an icon 72 for calling up the list of stamps, a quick call
`icon 73 for immediately calling a particular page, a key
`word-setting icon 74 for finding information, a 9-page
`display icon 75 for displaying the information of nine pages
`at the same time on the tablet screen, and an icon 76 for
`specifying other menus. These icons are shown in the form
`of patterns or the like which visually show the functions of
`the icons. When one of the icons is pointed at, the contents
`of, or information identifying, the icon are displayed on the
`screen.
`
`For instance, among the icons mentioned above, if the
`icon 72 for calling up the list of stamps is pointed at, then
`the list of stamps as shown in FIG. 4 will appear on the
`screen of the tablet 28. These stamps are used to manage
`information by each page or to provide background pictures.
`The meanings and functions of the individual, stamps will be
`described later.
`
`When the 9-page display icon 75 is pointed at after the
`power switch is turned ON, a total of nine pages of infor-
`mation are displayed at the same time in reduced sizes,
`including four pages each preceding and following a par-
`ticular page which is the page displayed when the power
`switch is turned ON and which is normally the page previ-
`ously processed. Therefore, this icon serves also as an index;
`however, no further description will be given about this icon
`because it is not directly connected to the present invention.
`In such a pen computer when characters or line pictures
`are written on the screen of the tablet 28 with the input pen
`51, the CPU 21 inside reads coordinates from the digitizer
`281 and displays the writing trace in the corresponding
`position of the LCD 282 and stores the coordinate data at a
`predetermined address of the flash memory 33.
`To input an image through the CCD camera 23, the lens
`23a of the CCD camera 23 is pointed at the image to be
`captured and the camera button 39 is first depressed halfway.
`This causes the image entered through the lens 23a to be
`projected as an animation on the screen of the tablet 28; and
`when the camera button 39 is further depressed, the image
`is locked and the locked image is captured. The image signal
`is converted to a digital signal by the CCD camera controller
`24 before it is stored at a predetermined address in the flash
`memory 33.
`To input spoken information, the voice input button 40 is
`depressed to enable audible speech to be captured through
`the microphone 25; the spoken sounds are then amplified
`through the amplifier 26 and converted to a digital signal by
`the analog-to-digital converter 27 before it is stored at a
`predetermined address in the flash memory 33.
`The operation for capturing information is performed in
`units of screens, i.e. on a page basis. The following will
`describe the processing procedure.
`If the pen computer has never been used, when the power
`switch 36 is turned ON, nothing will be displayed on the
`screen of the tablet 28; this screen will be regarded as the
`first page. However, the following will describe an example
`wherein some information has already been captured into
`the first page and additional information will be captured on
`the second and subsequent pages.
`In this example, the user of the pen computer will meet a
`person, whom he has never met before, to have a business
`discussion during which he will capture information regard-
`ing the person and the details of the discussion and also
`information about a product, which is the topic of the
`business discussion.
`
`When the user first turns ON the power switch 36, the first
`page into which information has already been captured will
`21
`
`21
`
`
`
`US 6,710,791 B1
`
`7
`be displayed. Pressing the next page button 37 causes the
`screen of the second page, into which no information has
`been captured yet, to be displayed. With the blank second
`page on the screen, in order to capture the image of the face
`of the person with whom the user is meeting, the user points
`the lens 23a of the CCD camera 23 at the person and
`depresses the camera button 39 halfway as previously
`described,
`then further, e.g. fully, depresses the camera
`button 39. This causes the then-existing face image, which
`is a stationary image, to be captured and the face image to
`be displayed on the screen of the tablet 28 at the same time,
`as shown in FIG. 5A; the image data is stored at a prede-
`termined address of the flash memory 33. The position and
`size of the area where the image is displayed may be preset
`in the display area on the screen of the tablet 28 or they may
`be set according to the situations of each case.
`FIGS. 5A and 5B show examples where an area of about
`one-quarter of the display screen at top left thereof is set as
`the image area.
`The user of the pen computer then writes with the input
`pen 51 memo-like information including the name of the
`person, the company name and the department or section to
`which he belongs as the information regarding the person.
`The ink information, such as characters or line drawings,
`entered with the input pen 51 is displayed on the screen of
`the tablet 28 as the user draws them and it is also stored at
`
`a predetermined address in the flash memory 33.
`Furthermore, to record an important part of the discussion
`in terms of spoken statements, the voice input button 40 is
`depressed to capture the such statements. The captured voice
`is subjected to digital conversion and stored as a voice signal
`at a predetermined address in the flash memory 33. Upon
`completion of capturing the voice, an icon 52 indicating the
`completion of recording appears at a predetermined point on
`the screen of the tablet 28. This icon 52 is used also for
`
`function reading. To be more specific, when the data on the
`page is read later, the voice information is read and repro-
`duced from the predetermined address in the flash memory
`33 by pointing at the icon 52 with the input pen 51.
`FIG. 5A shows an example where the information which
`has been captured according to the procedure described
`above is displayed on the screen of the tablet 28, that is, the
`information on the second page. As it is seen from. FIG. 5A,
`the visual information of the page information of one page
`unit is given by face image information 61, ink information
`62 such as characters and line drawings, and the icon 52
`whi
