## Background
TECHNICAL FIELD
The present invention provides an apparatus and method for facilitating selection of an operating mode of a multi-function device.
BACKGROUND OF THE INVENTION
Over the last several years, devices that perform several document-processing functions have been developed. These devices are known generally as multi-function devices. One type of multi-function device, known as a MOPIER® (Multiple Original Printer), is a networked printer that combines the functionalities of a printer and a photocopier, quickly printing multiple copies of documents of a high quality, and at a lower cost, than traditional copiers. Some multi-function devices are capable of performing even more tasks. For example, some have the capability to operate as a copier, printer, scanner and facsimile machine.
Multi-function devices offer several potential advantages over the use of multiple individual devices. For example, a single multi-function device generally uses less space than multiple individual devices. Also, the cost of a single multi-function device may be lower than the cost of multiple individual devices. However, current multi-function devices also suffer from some drawbacks. One possibly significant drawback is the complexity of the operation of the device.
Typical multi-function devices have a control panel with both an array of buttons, and an LCD or other flat panel display. In general, the complexity of the control panel, including the number of buttons on the panel and the number of messages and options shown on the display, increases with the functionality of the device. For a device with fax, print, copy and scan functions, the control panel may be sufficiently complex to intimidate new users, and even to confuse experienced users. For example, a prominent feature on a typical multi-function device is the display. Thus, users may look first to the display for information on the operation of the device. However, the display may not indicate to users how to change between operating modes, or even which operating mode the machine is currently in. While the controls allowing a user to switch operating modes generally are marked, they may not be obvious enough to overcome the initial confusion and intimidation felt by new or inexperienced users when looking at the complex control panel.
Furthermore, because of space and efficiency considerations, there is generally no single control panel for each function. Instead, each individual button on the control panel typically performs a different task in each of the different operating modes. Thus, the difficulty presented by having to learn to operate the control panel in each different operation mode also may intimidate new users. As a result, these new users may choose not to use the multi-function device, and instead opt to use less efficient, but simpler, older devices.
SUMMARY OF THE INVENTION
The present invention provides a multi-function device configured to perform a plurality of functions related to document reproduction and transmission. The multi-function device includes a display which provides a graphical user interface, the display being configured to present an idle screen when none of the plurality of functions is in use. The idle screen includes a plurality of fields, each field representing a function performed by the multi-function device, wherein selection of a particular field by a user causes presentation of a control interface for the function represented by the particular field. The multi-function device may include a touch screen input to allow a user to select a field.

DETAILED DESCRIPTION OF THE DEPICTED EMBODIMENTS
One embodiment of a multi-function device according to the present invention is shown generally at 10 in FIG. 1. Multi-function device 10 includes a body 12 enclosing various document processing systems, and a control panel 14 that provides for user control of multi-function device 10.
Control panel 14 is positioned on an upper portion of multi-function device 10, at a location where it is easily viewable and accessible by a user. Control panel 14 includes one or more control buttons 16, (e.g. a power control button) and includes a display 18 which provides a graphical user interface. Display 18 is sized and positioned on control panel 14 in such a manner as to draw a user's eye when the user looks at the control panel.
When multi-function device 10 is not in use (i.e. is idle), an idle screen is presented on display 18. The idle screen, described in more detail below, is divided into a plurality of fields representing the individual functions performed by the multi-function device. Using the graphical user interface, the user can select a particular field corresponding to a desired function. This opens a control interface screen for the desired function on display 18, typically to the exclusion of the idle screen or other control interface screens.
Displaying all of the individual functions of the multi-function device on the idle screen offers a new user a very simple-to-understand interface for selecting a device operating mode. Thus, the use of such an idle screen may make multi-function device 10 seem less intimidating to many users, who may therefore be less hesitant to use it. While multi-functional device 10 is shown as a desktop-sized item in FIG. 1, it will be appreciated that a multi-functional device according to the present invention may take the form of any desired document production/transmission device, large or small.
FIG. 2 shows generally at 20 one example of a suitable idle screen. Idle screen 20 includes four fields, corresponding to four exemplary operating modes of multi-function device 10: a print field 22, a copy field 24, a scan field 26 and a facsimile field 28. Each of fields 22, 24, 26 and 28 has text indicating the function represented by the field. In the depicted embodiment, the function represented by each field 22, 24, 26 and 28 is indicated simply with a word identifying the function. However, any desired text, icon, object or other designator may also be used to indicate the functions represented by the fields.
Similarly, the fields may be arranged on display 18 in any desired arrangement. In the depicted embodiment, the four fields are arranged as quadrants on display 18, fully occupying the entire display, and the text indicating the function represented by each field is positioned prominently in the center of the field. Arranging the four fields as quadrants is advantageous, as it gives each field the largest possible surface area, facilitating the selection of a desired field. However, the fields may also be arranged in any other desired manner without departing from the scope of the present invention. For example, the fields may be arranged in a vertical fashion down a single column, or may be arranged horizontally across display 18.
The choice of a suitable arrangement of fields on idle screen 20 may depend in large part upon the number of fields displayed on the idle screen. While idle screen 20 typically has only as many fields as there are functions of multi-function device 10, it will be appreciated that idle screen 20 may also have either more or fewer fields. For example, idle screen 20 may have additional fields for such device-wide functions as putting multi-function device 10 in a sleep mode or power-down mode. Likewise, idle screen 20 may display a lesser number of fields in the form of broad, higher-level categories under which the individual functions are grouped.
Turning now to the graphical user interface, any suitable selecting device may be used to allow the selection of a desired field. Examples of suitable selecting devices include a mouse or trackball. Preferably, however, the graphical user interface utilizes a touch screen input as a selection device. A touch screen input is a type of display screen that has a touch-sensitive transparent panel covering the screen. Instead of using a mouse or trackball, a user can select a desired field by touching the screen with a finger. The use of a touch screen input is advantageous because it is simpler and quicker to use in the context of a display screen on a machine than other selection devices. Additionally, the large size of fields 22, 24, 26 and 28 on display 18 allows a desired field to be easily selected without a significant risk of error.
As mentioned above, and as shown in FIG. 2, the selection of a field on idle screen 20 causes an interface associated with that field to open on display 18. For example, the selection of print field 22 opens a printer interface 32. Similarly, selection of copy field 24 opens a copier interface 34, selection of scan field 26 opens a scanner interface 36, and selection of fax field 28 opens a facsimile interface 38. In the depicted embodiment, selection of a desired field opens the desired interface to the exclusion of any other interfaces. However, it will be appreciated that the desired interface may also open across only part of display 18, leaving room for other information, such as a reduced-size idle screen.
FIGS. 3–6 show printer interface 32, copier interface 34, scanner interface 36 and facsimile interface 38 in more detail. Each of the interfaces includes a plurality of controls operable by the touch screen input (or other input device). It will be appreciated that the controls shown in the depicted interfaces are merely exemplary, and that actual interfaces may have any other desired controls or layout.
Referring first to FIG. 3, printer interface 32 includes ordinary printer controls, such as an on-line control 40 (for opening or closing the connection between the printer and an attached document transmission device), form feed control 42 (for feeding a sheet of paper through the printer), print cancel control 44 (for canceling a print job), and controls for accessing more complex printer functions, such as a menu control 46 (for opening a menu screen), select control 48 (for selecting a menu choice), and enter control 50 (for executing the selected choice). In the depicted embodiment, each of these controls is depicted on display 18, but some of these controls may be positioned on other parts of the control panel if desired.
Printer interface 32 also has a dialog box 52 for reporting printer status, errors, etc., and a return control to return to idle screen 20. Finally, printer interface may include a title 56, which identifies the interface as the printer interface so a user approaching the machine can quickly tell which mode of operation multi-function device 10 is in.
Next, referring to FIG. 4, copier interface 34 may include any desired controls for the operation of the copier function of multi-function device 10. Several exemplary controls are shown in FIG. 4, including a start control 60 (for starting a copy process), a stop/clear control 62 (for stopping/resetting a copy process), and a number pad 64 (for selecting the number of copies to be made, etc.). Also, copier interface 34 may include a return control 68 (to return to idle screen 20), a dialog box 66 (for communicating machine status information to a user), and a title 70 identifying the interface as the copier interface.
Referring next to FIG. 5, scanner interface 36 may also include any desired controls for the operation of the scanner function, such as color and black/white selection controls 80 and 82, respectively, a preview control 84 (allowing a user to first preview a scanned document before saving it to a file), and a “scan to” control 86 (allowing a user to select a file format for the scanned image). Scanner interface 36 may also include controls such as a start control 88, a stop control 90, and a return control 94 for returning to idle screen 20. Finally, scanner interface 36 also may include a dialog box (for indicating scanner status information to a user), and a title 96 for identifying the scanner function as the current mode of operation.
Finally, referring to FIG. 6, facsimile interface 38 may include any desired controls for the operation of the facsimile function of multi-function device 10. Exemplary controls shown in FIG. 6 include a clear control 100 (for resetting the facsimile function), a pause control 102 (for pausing transmission), a set control 104 (for setting machine modes, entering speed dial numbers, etc.), a numeric keypad 106 (for dialing the receiving machine's number), a start control 108 (for starting transmission), a stop control 110 (for stopping transmission) and a return control 112 (for returning to menu screen 20). Finally, facsimile interface 38 may include a dialog box 114 and a title 116 identifying the facsimile function as the current mode of operation.
The present invention also provides a method of facilitating the selection of an operating mode of a multifunction device. A first embodiment of a method according to the present invention is shown generally in FIG. 7 at 200. Method 200 first includes presenting an idle screen with a plurality of user selectable fields to a user at 202. As described above, the idle screen may have any desired appearance, and may allow the selection of any functions performed by the multi-function device. Next, at 204, an input is received from the user selecting a field corresponding to a desired multi-function device function. Upon receipt of the user input at 204, a control interface associated with the desired function is presented on the display at 206. The control interface (or sub-screens of the control interface) remains displayed until an input is received at 208 from the user selecting to return to the idle screen. Upon receipt of this user input, the idle screen is again presented on the display at 210.
