ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates generally to the field of graphical user interfaces and, more particularly, to a portable hand-held appliance for capturing images through digital scanning that has a graphical user interface for displaying the captured images for user manipulation and processing, and communicating those images to another device or appliance.
Intangible information is a vital business asset that can be exploited for competitive advantage if managed properly. In the past fifteen years, improvements in information processing have been achieved primarily from the widespread use of microcomputers in the workplace and their application in local and wide area networks. Through such applications as electronic mail (email) and networked access to document storage servers, the electronic communications market has exploded. Nevertheless, business is still far from reaching a “paperless” workplace. For example, according to a 1993 report by BIS Strategic Decisions (hereinafter BIS), an information technology consulting firm, more than 90 billion documents were created in 1992 and more than 1 trillion copies of those documents were made. Moreover, BIS estimated that printing and copying expenses average between 6% and 13% of a typical company's revenue. These statistics illustrate the economic savings available for those businesses that are able to merge paper and technology in a unified information processing strategy.
One tool that has proven useful for translating between paper and electronic information is the digital scanner. Scanner-enabled document distribution endows paper-based documents with the speed and convenience of electronic communications. A desktop scanner or network scanner allows business professionals to scan paper-based documents, manage them effectively and distribute them in a timely fashion. Users can share and distribute information easily by scanning directly to their email or PC fax applications. The growing popularity of fax modems and email is driving the acceptance of scanner-enabled document distribution in offices of all sizes. Fax/modem capabilities, which are available with virtually all modern PCs, enable users to send and receive faxes directly from a computer—at their desk or while traveling—and to check email remotely.
Nevertheless, while scanners are ideal for users who need to disseminate paper-based information to colleagues through PC facsimile and/or email, traditional flatbed scanners lack the convenience and flexibility that users have become accustomed to through such products as notebook computers and cellular phones. Hand-held scanners are an improvement in this regard; however, they are typically dependent on a host computer for displaying the scanned images and for providing power. U.S. Pat. No. 5,550,938 to Hayakawa et al. (hereinafter Hayakawa) discloses a portable image scanner designed to overcome these disadvantages. Specifically, Hayakawa discloses a hand-held cordless image scanner having a display/control screen, a memory for storing scanned images, a self contained power supply and an interface that allows the scanner to be received by a host computer as a memory card for transferring stored images from the scanner to the computer. While Hayakawa's scanner is effective in breaking the dependency on a host computer for image display and power, it still has several drawbacks. For example, Hayakawa's scanner offers no image processing features other than the capabilities of storing or discarding a newly scanned image and reviewing those images that have been stored previously. More advanced image processing would necessarily be done after transfer to a host computer. Moreover, Hayakawa does not offer a graphical user interface (GUI) containing icons and/or animations to assist users in operating their device. Finally, transfer of images is limited to those devices having ports for receiving an external memory card or the capability of reading the scanner memory through a memory card drive.
Accordingly, what is sought is a portable, hand-held image capturing device that allows users to process or manipulate captured images in the device and the ability to communicate the images directly to some other unit such as a computer, printer, or facsimile machine. In addition, the image capturing device should provide cordless operation and use a standard interface for transferring images to other devices. A GUI is preferred to assist users, particularly novices, in operating the device.
SUMMARY OF THE INVENTION
Certain objects, advantages, and novel features of the invention will be set forth in the description that follows and will become apparent to those skilled in the art upon examination of the following or may be learned with the practice of the invention.
To achieve the advantages and novel features, the present invention is generally directed to a portable hand-held image capture and communication appliance and method of using same by which images may be captured via capturing means and saved in an internal memory. The appliance includes a processor for manipulating and exhibiting the images on a built-in display screen. Program code stored in the internal memory includes an image or page attachment module that allows the user to associate captured images with one another (i.e., electronically attach the images) to form a group and provides a graphical representation of this association on the display screen.
According to another aspect of the invention, the program code includes an image or page detachment module, which allows the user to disassociate captured image(s) (i.e., electronically detach the image(s)) from a previously formed group and a menu
avigation module that provides the user with a list of possible actions and processes responses thereto.
The page attachment module includes code segments for displaying an animation that is a graphical representation of pages attached to one another to form a group. In the preferred embodiment, the animation shows a page or group come into view on the display to substantially overlay the page or group being attached to form a new group. An icon that serves as a metaphor for the attachment (e.g., a paper-clip) is placed in motion on the display during the overlay process and comes to rest once the grouping is complete. The animation completes with the overlaying page or group folding to the back of the new group, displaying the attached page or group. The overlay of the images combined with the behavior of the attachment metaphor provides a visual cue for the user that the pages have indeed been electronically attached or grouped. Pages within a group are displayed in response to user input by folding pages to the back of the group to move towards the last image of the group and by folding pages to the front of the group to move towards the first page of the group. A momentary icon is displayed on the screen when the group is first formed and as the user navigates within the group that identifies the logical position of the current page in the group.
The image detachment module includes code segments for displaying an animation that is a graphical representation of page(s) detaching from a group. In the preferred embodiment, the user navigates within the group by folding pages to the back of the group until reaching a page where the group is to be divided. If detachment is chosen from a menu provided on the display screen, the pages that were folded behind the group will fold back to the front of the group and will then be removed from the display screen, creating a separate group. Similar to the attachment animation, an icon that serves as a metaphor for the attachment or grouping (e.g., a paper-clip) is placed in motion on the display during the removal process. If more than one page remains after the detachment, the icon will come to rest to identify the remaining images as a group. If only one image remains, the icon disappears.
The appliance according to the present invention has many advantages, a few of which are highlig
