`
`A HAND-HELD DISPLAY DEVICE AND A
`METHOD OF DISPLAYING SCREEN
`IMAGES
`
`Field of the Invention
`
`The present invention relates to a hand—held display
`
`device and a method for its use with an electronic device
`
`to display a complete or a determined part of a screen
`
`image.
`
`Description of the Prior Art
`
`Several electronic devices, such as a mobile tele-
`
`phone, a PDA (Personal Digital Assistent), an organizer, or
`
`a PC (personal computer) etc. are provided with a display
`
`or a monitor for displaying different kind of information.
`
`A typical personal computer system, notebook, or hand—held
`
`computer consists of a system unit, storage means, a
`
`display, keyboard and a mouse or other interactive input
`
`devices such as a digitizing tablet,
`
`joystick,
`
`lightpen
`
`etc.
`
`to control
`
`the computer.
`
`The primary attributes of a display is the size of
`
`the display screen;
`
`the resolution of the display; and
`
`whether the display is monochrome or in colour. The size of
`
`a display screen can vary from,
`
`for example,
`
`5 to 25 inches
`
`in diagonal dimension. The quality of output or the resolu—
`
`tion of a common display or monitor is for example 640x480,
`
`800x600, or 1024x768 pixels.
`
`There is a variety of displays available from differ-
`
`ent vendors. These displays are designed to accomplish par-
`
`ticular functions. An engineer needs a large high—resolu—
`
`tion monitor for CAD—applications and a smaller monochrome
`
`monitor for the display of text and graphic information. A
`
`ful1~page colour monitor can be utilized for both landscape
`
`and portrait presentations. Also, hand—held data entry de-
`
`vices or computers are provided with a small display. A
`
`SCEA EX. 1007 Page 3
`
`SCEA Ex. 1007 Page 3
`
`

`
`WO 99/18495
`
`PCT/SE98/01763
`
`common hand—held data entry device has a limited keyboard
`
`and some kind of storage capability for the data. Another
`
`hand—held data entry device combines a hand—held optical
`
`wand with a keyboard. Stock clerks use such devices in
`
`stores to collect and enter reorder data.
`
`For some purposes small flat—panels are required to
`
`save space. Flat—panels are used in conjunction with small
`
`size electronic devices such as notebooks, hand—held com-
`
`puters, mobile telephones etc.
`
`Many vendors offer or are just about to offer hand-
`
`held computers. These computers are provided with flat-
`
`panels having for example a 640x240 resolution touchscreen,
`
`or 480x240 resolution touchscreen. Such panels or display
`
`screens cannot be too limited in size and resolution to be
`
`useful for their intended purpose, i.e.
`
`to present general
`
`software applications such as word processing, desktop pub-
`
`lishing, spreadsheet, databases,
`
`internet applications etc.
`
`The limitations are set in view of the sight properties of
`
`a human being.
`
`Consequently, a problem associated with prior art
`
`computer configurations is that access is needed to several
`
`types of computers provided with different displays suit-
`
`able for different kinds of applications. As described
`
`above, a very small sized flat—panel of a hand—held data
`
`entry device, a mobile telephone, or a computer etc.
`
`is not
`
`at the same time capable of display full—screen documents
`
`in a proper and readable way.
`
`JP—A—7 234 664 discloses a document
`
`image display,
`
`which reads out the contents of a document using a scanner
`
`and the image of the document is stored in a page memory.
`
`An area of the document specified by an operator is read
`
`from the memory and then magnified. The magnified area,
`
`stored in a working memory,
`
`is then displayed on an opera-
`
`tion display.

`
`Sumary of the Invention
`
`The present invention is directed to an improved dis-
`
`play device for use with an electronic device, which over-
`
`comes one or more of the limitations and disadvantages of
`
`the related art.
`
`It is an object of the present invention to provide a
`
`hand—held display device for use with an electronic device,
`
`said display device being suitable for the purpose of a
`
`hand—held data entry device as well as for both landscape
`
`and portrait presentations of a full—page word processing
`
`document. Further, it can satisfy the needs of an engineer
`
`working with CAD—applications as well as for the display of
`
`text and graphic information. Also, hand—held computers can
`
`be provided with a display device of the present invention.
`
`Consequently, another object of the present invention
`
`is to provide a hand-held display device for use with a
`
`computer to display a complete or a determined part of a
`
`screen image in a proper size with regard to the current
`
`needs or requirements of a user.
`
`Still another object of the invention is to provide a
`
`display device incorporated in an electronic device such as
`
`a mobile telephone, a PDA (Personal Digital Assistent), an
`
`organizer, a data terminal to display a complete or a
`
`determined part of a screen image in a proper size with
`
`regard to the current needs or requirements of a user.
`
`These objects are accomplished by a display device
`
`having movement sensitive means such as a micro gyroscope,
`
`strain gauge, piezo—electric, or equilibrium of force
`
`accelerometer etc incorporated in said display device,
`
`thereby being responsive to movements in the space for
`
`displaying the complete screen image in different magnifi-
`
`Cations, or in different parts.
`
`Further, a method of displaying a complete or a de-
`
`termined part of a screen image in a proper size with re:
`
`gard to the current needs or requirements of a user is also

`
`provide by the invention, wherein said display device is
`
`activated by pressing an activation control button of said
`
`display device, and said display device is moved essen-
`
`tially in the plane of said display device, whereby differ-
`
`ent parts of a complete screen image are shown on said dis-
`
`play screen, and/or said display device is moved essen-
`
`tially in a direction perpendicular to the plane of said
`
`display device, whereby the magnification of said screen
`
`image is changing.

`
`data terminal or a computer to display a complete or a de-
`
`termined part of a screen image is shown in FIG 1. Said
`
`display device is provided with control circuits, not shown
`
`in FIG 1. A display screen 2 and control buttons 3, such as
`
`touch control buttons, are incorporated in said display de-
`
`vice l and connected to said control circuits. For connec-
`
`tion with a computer or a network connection means 4,
`
`for
`
`example an IR (infra red) or radio transmitter/receiver, or
`
`a connection cabel etc.
`
`is attached to the display device.
`
`Movement sensitive means 6 comprising a micro gyro~
`
`scope, strain gauge, piezo—electric, or equilibrium of
`
`force accelerometer etc is incorporated in said display de-
`
`vice l and connected to said control circuits, said display
`
`device being responsive to movements in the space for dis-
`
`playing the complete screen image in different magnifica-
`
`tions, and/or different parts of a screen image.
`
`Power supply for the display device is provided by
`
`for example local batteries, sunlight power, kinetic
`
`energy, or the power supply of an attached computer.
`
`One of said control buttons 3 is an activation con-
`
`trol button provided for activation of said display device
`
`1 to be responsive for movements. Thus, said display device
`
`1 is activated by pressing said activation control button
`
`3, and then by moving said display device 1 essentially in
`
`the plane of said display device, different parts of a
`
`screen image are shown on the display screen 2.
`
`This is schematically illustrated in FIG 2, wherein a
`
`cutting 8, corresponding to the image shown on the display
`
`screen 2
`
`in FIG 1,
`
`is surrounded by a superimposed dashed
`
`virtual display device 9 corresponding to the size of the
`
`display device l. when said virtual display device 9 is
`
`moved around on said screen image 7, different cuttings 8
`
`are covered. Correspondingly,
`
`these cuttings 8 are dis-
`
`played when the real display device 1 is moved in the plane
`
`of said display device.

`
`As shown in FIG 3, a user l0 is moving said display
`
`device up and down,
`
`illustrated by an arrow 11, and to the
`
`left and right,
`
`illustrated by an arrow 12,
`
`to present
`
`different parts of the screen image 7.
`
`In a particular po-
`
`sition in the space the cutting 8 of the screen image 7 is
`
`presented on the display screen 2. Hence, it is possible
`
`for the user of the display device 1 to read text that does
`
`not actually fit into the small display screen 2, by moving
`
`the display device a short distance in space in the plane
`
`of said display device.
`
`By activation of said display device 1 by pressing
`
`said activation control button 3 and then moving said dis-
`
`play device back and forth, essentially in a direction per-
`
`pendicular to the plane of said display device,
`
`illustrated
`
`by an arrow 14,
`
`the magnification of said screen image 7
`
`is
`
`changed or the image is zoomed. As shown in FIG 3 and in
`
`more detail in FIG 4, it is possible to zoom out as much as
`
`an overview of the complete screen image 7 is shown on the
`
`display device 1.
`
`It should be apparent that the present
`
`invention pro-
`
`vides an improved display device 1 and a method for use
`
`with an electronic device such as a computer 13 to display
`
`a complete or a determined part of a screen image 7 by
`
`moving said display device 1 in the space, wherein differ-
`
`ent parts of the screen image 7 are shown in different
`
`magnifications on said display screen 2. Although the
`
`invention has been described in conjunction with a specific
`
`embodiment thereof,
`
`this invention is susceptible of
`
`embodiments in different forms, with the understanding that
`
`the present disclosure is to be considered as an exempli—
`
`fication of the principles of the invention and is not
`
`intended to limit the invention to the specific embodiment
`
`illustrated.
`
`For example,
`
`in another embodiment of the invention
`
`the different parts: display screen, movement sensitive

`
`means, control buttons, electronic circuits and/or
`
`connection means, of said display device can be
`
`incorporated as a single unit or as separate parts in an
`
`electronic device such as a mobile telephone, a PDA
`
`(Personal Digital Assistent), an organizer, data terminal,
`
`or a hand—held computer, wherein the operations described
`
`above are performed in a similar manner. Consequently,
`
`the
`
`conventional keypad of the particular electronic device may
`
`comprise control buttons for the display functions of the
`
`invention. Further,
`
`these kinds of electronic devices,
`
`provided with a display device of the invention, can work
`
`as stand alone devices with no need for connection means,
`
`as well as devices having a connection with another
`
`electronic device or network.
`
`In a particular embodiment of the invention said dis-
`
`play device is incorporated in a mobile telephone unit pro-
`
`viding both computer and telephone facilities,
`
`shown in FIG
`
`5. The conventional transmitter/receiver units of the
`
`mobile telephone may be utilized as connection means for
`
`connection with other electronic devices or networks.
`
`Different kinds of technologies can be utilized for
`
`the display screen 2, such as LCD (liquid crystal display),
`
`gas plasma, EL (electroluminescent), TFT (thin film
`
`transistor) etc.
