Description

DETAILED DESCRIPTION OF THE INVENTION (Technical field to which the invention pertains) The present invention uses a rewritable optical file and an input/display integrated device. The present invention relates to an information retrieval device that is small and highly portable.

(Prior art) Recently, with the digitization of information processing, large amounts of information are carried around on storage media such as floppy disks and optical disks. There is a need to effectively present reference materials and, if necessary, process data on the spot or transfer results to a host computer. For this reason, there is a demand for information storage and retrieval terminals that are small and highly portable.

As for the media here, it is easier for humans to understand information using multimedia that efficiently mixes text, explanatory diagrams, videos, still images, etc. than single media such as text, for example, information memorized by one person. After 80 hours, the survival rate is approximately 10% when acquired only by hearing and 20% when acquired only by sight, but it is said to reach over 60% when acquired by hearing + visual. , Presenting information by making full use of multimedia is extremely effective in presentations and the like.

Furthermore, by constructing and utilizing hypermedia that networks key data in various media, it becomes an extremely powerful means for organizing one's own data and presenting it to others.

With the emergence of such needs, the increase in the capacity of semiconductor memories, and the use of LSIs for CPUs and their peripheral circuits, various types of handy terminals are becoming widespread.

For example, a card calculator with semiconductor memory added to it, an electronic notebook-like device with phone book functions, schedule management functions, etc., a portable word processor, and a parancon. There are portable video playback devices, electronic OHPs, etc.

However, among these, ordinary portable terminals that use semiconductor memory as a storage medium have a limited storage capacity, and are limited to character and numeric data.

Audio 9 Unable to store large amounts of data such as images 6
Also. Because of its compact size, the keyboard is small and has poor operability, and requires a lot of effort to input data.

On the other hand, current small personal computers and word processors are called laptop-sized devices, which cannot realistically be considered portable devices. Furthermore, floppy disks are mainly used as storage media, and they still do not have enough capacity to handle multimedia.

Optical file systems are available as large-capacity storage media, but they are usually desk-side systems.

It is not a portable format, but a write-once format, which is not suitable for free editing.

As described above, conventional portable information terminals have drawbacks in storage capacity and operability. In particular, the small storage capacity is a fatal drawback in realizing portable information storage and retrieval functions based on multimedia.

Also, portable video playback devices for presentations have a large storage capacity.

Since the information that can be presented is video, audio, and images, it is
1-. It is not suitable for images or shapes, and arbitrary searches are not possible.
Furthermore, since the screen size of the monitor is limited,
At the same time, it is not possible to give a presentation in front of a large number of people.

Electronic OHPs have attracted attention in recent years because they can project both sides of a computer onto a screen, but because they require a host computer, the places where they can be used are limited.
The portability of P itself is also insufficient. Furthermore, the storage medium is a floppy disk, which has insufficient capacity to handle multimedia and has poor display performance.

In addition, while the storage capacity of a normal mobile information terminal is several tens to several megabytes for a semiconductor memory type and several hundred to several megabytes for a floppy disk type, this device has a storage capacity of several hundred megabytes. It is a capacitive storage device with advanced search and display input functions, capable of storing large amounts of data, and recording digitally on the storage medium regardless of the type of media. Therefore, similar to CD-I and the like, various media can be mixed and manipulated and processed.

Note that in CD-I, due to sequential access,
While the seek time is 0.5 to 1 second, this device uses random access, so the seek time is only about 100 m5, and high-speed access is possible.

FIG. 3 is a diagram showing the configuration of software implemented in the apparatus of this embodiment. The boot program is stored in O8M17 of the main body, and starts automatically when the power is turned on or when the magneto-optical disk 4 is inserted.
, AP are uploaded to the main body RAM+8, the application program (AP) is automatically started, and desired processing is started.

22) The processing functions of the device of the present invention are similar to those of conventional personal computers (PCs), and most AP software for personal computers can be ported, such as database software, spreadsheet software, word processing software, etc. Communication software, schedule management software, diagramming software, etc. are applicable. However, since the device of the present invention is equivalent to a device with a large-capacity fixed disk, by integrating these AP software mainly with the database function and making full use of the display input and body shape devices, it is possible to It is possible to realize advanced information retrieval functions with a superior human-machine interface.

FIG. 4 is a diagram showing an outline of the operation flow of the embodiment device. In FIG. 1 (1), as described above, after the power supply 13 is turned on or the magneto-optical disk 4 is inserted.

In (2) of the same figure, after starting the application software, search conditions for finding desired information are set, and information matching the conditions is displayed on the display 10. Note that if the information hit at this time is expressed in a plurality of media, the data is restored for each media and then each media is displayed in a composite manner. For example, a still image (gradation image)/explanatory text (text) and seven handwritten memos (dot images) are displayed in an overlapping manner.

Note that each medium is stored in the frame memory F in the control circuit 8.
It is set to RAM 8c. Furthermore, if audio is present, the audio is also played at the same time as the image is displayed.

FIG. 3(3) shows a flow when information obtained from the outside via the expansion bus 14 or text/handwritten information input from the input tablet 9 is edited and then saved on an optical disk. First, after assigning a search key, attribute data (media type, encoding method, etc.)
is determined and saved on the magneto-optical disk 4.

FIG. 4 (4) shows a task selection flow in various phases within the AP software. First, a list of candidates for tasks to be processed first is displayed on the display 10, and a desired task is input (point touch) according to the instructions.

Figure 5 is an example of a task selection menu screen controlled by the AP software, where 19 is a function key and 20 is a function key.

Each of these keys is a soft switch, and selection contents are input by point-touching the input bezel 2. In this example, ``Search,'' ``Data Transfer,'' ``Data Edit,'' and ``Previous Menu'' are displayed. For example, if you want to select ``Data Edit,'' touch the area where the words ``Data Edit'' are displayed. If so, the data editing task is started, and the display of the next selection menu or execution of the task is started ljN.

This is how input and display are integrated.

Since only the minimum necessary keys are displayed each time an input operation is performed, key operations are easier than conventional keyboard operations, and the man-machine interface is significantly improved. Also,
If a person who is accustomed to conventional keyboards wishes to operate the system using a keyboard, a dedicated keyboard (not shown) may be connected via the expansion bus 14.

Note that when handwritten input is specified as the task content, the data display section 22 is a full-scale handwritten input screen, which allows handwritten input similar to telewriting and can be used as a handwritten note. ,
You can add handwritten notes etc. over the still images (9 drawings, etc.).

FIG. 6 is an example of the data format (logical structure) of information stored on the magneto-optical disk 4. As shown in FIG. Content data is variable length data of a single medium, because even if the display size or audio playback time is constant, the amount of data changes depending on the information density of the content due to encoding.

A preamble and boss 1 to ampule are added to each content to clarify data divisions and provide attributes (media type, encoding format, index, etc.). In addition, there is connection data in the preamble, which is a set of data attributes consisting of multiple contents, and is used to express connection relationships with other related media data when expressing specific information in multimedia. This data is necessary for clarification.

In this way, each medium is represented by digital data, handled uniformly, and mixedly stored in the magneto-optical disk 4. As a result, by adding network information of related content to application programs and data attributes, it is easy to construct hypermedia in which a network is formed semantically.For example, in a product catalog, a predetermined part of the display screen can be Just touch the point,
Explanation of technical terms, demo videos, related products, etc.
