## Background
TECHNICAL FIELD
The present invention relates generally to transferring data between computers, and more particularly to a data sharing software program for transferring of data from a source computer to a location on a target computer utilizing a drag-and-drop operation and a spring-loaded portal.
BACKGROUND
Technological improvements continue to be made in the area of data sharing software programs, which can reduce the need for face to face meetings. Specifically, software programs that enable data sharing can provide a way for end-users to collaborate through computers in order to achieve a desired task without the end-users having to be in the same physical location. For example, when multiple end-users are collaborating and sharing data to create a consolidated document (e.g., a text file, spreadsheet, or presentation), there often exists a challenge in regards to how to efficiently share the document between computers in a manner that enables a collaborative experience in editing the document.
Current technologies for data sharing between a source computer and a target computer include functionality for transferring of data through an e-mail attachment, a USB flash drive, a shared drive, an instant message, or a mouse-sharing software program. However, current software programs that enable the data sharing often require multiple steps, and do not provide an efficient and intuitive way to share data between computers.
Thus, the challenge of creating a data sharing software program for transferring of data from a source computer to a location on a target computer with minimal steps required by an end-user, and in a manner that is efficient and intuitive continues to persist.

FIG. 1 illustrates a computer system that includes computers 10 having data sharing software program 30 installed. Computers 10 are electronic devices that include desktops, laptops, and servers. Computers 10 each include CPU 12, operating system 14, RAM 16, ROM 18, storage 20 (which is a computer-readable hardware storage device) and TCP/IP adapter card 22. Computers 10 are each coupled to I/O devices 26 through an I/O interface 24. I/O interface 24 includes any system for exchanging information to or from an external device. I/O devices 26 include any known type of external device such as a display device (e.g., monitor), keyboard, mouse, printer, speakers, handheld device, facsimile, microphone, or webcam.
Furthermore, computers 10 are connected to each other through TCP/IP adapter card 22 and IP network 40, wherein the computers each have program 30 installed, and wherein the program enables data to be transferred between the computers with minimal steps required by an end-user. Specifically, program 30 requires initial setup and configuration on each of computers 10 by the end-user. The initial setup and configuration of program 30 on each of computers 10 includes enabling the computers to send and/or receive requests for transferring of data through a drag-and-drop operation provided by the program, and creating a corresponding list of computers to transfer data to. Thus, each of computers 10 can be a source computer and/or a target computer for the transferring of data. After completion of the initial setup and configuration of program 30 on each of computers 10, a configurable spring-loaded portal 312 will appear along an edge of displays (e.g., monitor) that are coupled to the computers. More than one configurable spring-loaded portal 312 may appear along an edge of a display that is coupled to computers 10, and the amount of the configurable spring-loaded portals that appear depends on the number of computers that are on the corresponding list created during the initial setup and configuration of program 30. Moreover, configurable spring-loaded portal 312 can be sized in a vertical dimension, and assigned a label (e.g., color and/or text), based on preference of the end-user, to make the configurable spring-loaded portal easily identifiable by the end-user.
FIGS. 2A and 2B are flowcharts illustrating key steps of data sharing software program 30 that is installed on computers 10, wherein computers 10 can be a source computer and/or target computer. Program 30 determines if an end-user is utilizing a drag-and-drop operation of the program for transferring of data between computers 10, from a source computer to a location on a target computer (step 200). Specifically, to determine if the end-user is utilizing the drag-and-drop operation of program 30 the program monitors I/O devices 26 for mouse input that includes coordinates of a mouse pointer, clicks of the mouse pointer, and movement of the mouse pointer. Thus, the drag-and-drop operation can be invoked by the end-user based on how the end-user positions, clicks, and moves the mouse pointer.
As shown in FIG. 2A, if program 30 of the source computer does not receive mouse input indicating that an object (e.g., image, file object, or text object) is being dragged over configurable spring-loaded portal 312, the program will determine that the end-user is not currently utilizing the drag-and-drop operation for transferring of data (decision 204, no branch), but the program will continue to monitor I/O devices 26 for mouse input to determine if the end-user is utilizing the drag-and-drop operation. Otherwise, if program 30 of the source computer receives mouse input indicating that an object is being dragged over configurable spring-loaded portal 312, the program determines that the end-user is utilizing the drag-and-drop operation for transferring of data (decision 204, yes branch) from the source computer to the location on the target computer, and the program expands the configurable spring-loaded portal from a closed position to an open position (step 208). Thus, configurable spring-loaded portal 312 is a window that can expand from the closed position to the open position, which is triggered when the coordinates of the mouse pointer correspond to a region of the configurable spring-loaded portal. Moreover, the location on the target computer where the end-user is transferring data to is previewable through configurable spring-loaded portal 312 of the source computer, which allows the end-user to view the desktop of the target computer even while transferring of data is being performed.
While configurable spring-loaded portal 312 is in the open position, program 30 continues to monitor whether the coordinates of the mouse pointer are inside the region of the configurable spring-loaded portal. If the coordinates of the mouse pointer are not inside the region of configurable spring-loaded portal 312, then program 30 will minimize the configurable spring-loaded portal to a closed position, and will continue to monitor I/O devices 26 for mouse input to determine if the end-user is utilizing the drag-and-drop operation for transferring of data from the source computer to a location on a target computer (decision 212, no branch). Moreover, if the coordinates of the mouse pointer are inside the region of configurable spring-loaded portal 312 (decision 212, yes branch), then program 30 retrieves a screen snapshot image of the location on the target computer (step 216). Subsequently, program 30 of the source computer overlays the screen snapshot image within configurable spring-loaded portal 312 that is on a display coupled to the source computer (step 220). After performing the overlay of the screen snapshot image, program 30 of the source computer continues to communicate with the target computer to obtain an updated screen snapshot image of the location on the target computer, based on the coordinates of the mouse pointer from the source computer (step 224). The updated screen snapshot image is utilized to refresh the configurable spring-loaded portal 312.
In addition, program 30 of the source computer monitors mouse input into the source computer to determine if the end-user is dropping the object at the location on the target computer (step 228). If program 30 determines that the end-user is not yet dropping the object, then the program continues to monitor mouse input into the source computer to determine if the end-user is dropping the object at the location on the target computer (decision 232, no branch). Otherwise, if program 30 determines that the end-user is dropping the object (decision 232, yes branch), then the program determines if the object can be pasted at the coordinates of the mouse pointer of the source computer at the location on the target computer. Program 30 can provide a visual indicator to guide the end-user to locations, on the target computer, that accept the transferring of the object (i.e., data). The visual indicator may include, but is not limited to, changing the appearance of the mouse pointer of the source computer while the mouse pointer is over a location on the target computer that does not accept the transferring of the object (i.e., data).
If the program 30 determines that the object cannot be pasted at the coordinates of the mouse pointer (decision 236, no branch), then the program will determine if the object can be conditionally pasted at the coordinates of the mouse pointer at the location on the target computer. If program 30 determines that the object cannot be conditionally pasted (decision 240, no branch), then the program aborts the drag-and-drop operation and alerts the end-user that the drag-and-drop operation was aborted (step 244). Alternatively, if program 30 determines that the object can be conditionally pasted at the coordinates of the mouse pointer (decision 240, yes branch) at the location on the target computer and that the end-user canceled the drag-and-drop operation (decision 248, yes branch), then the program aborts the drag-and-drop operation and alerts the end-user that the drag-and-drop operation was aborted (step 244). After the drag-and-drop operation is aborted, program 30 minimizes configurable spring-loaded portal 312 (step 272) and the program ends.
However, if program 30 determines that the end-user did not cancel the drag-and-drop operation (decision 248, no branch) or that the object can be pasted at the coordinates of the mouse pointer (decision 236, yes branch) at the location on the target computer, then the program estimates an amount of time to complete the transferring of data (step 252).
After performing the estimate, if program 30 determines that the amount of time is greater than or equal to a configurable threshold value (decision 256, yes branch), then the program will display a data transfer progress indicator on the source computer and the target computer (step 260). In addition, while the transferring of data is taking place, configurable spring-loaded portal 312 on the target computer that corresponds to the source computer will appear in a closed position on the display coupled to the target computer, the spring-loaded portal will flash to indicate the transferring of data is occurring, and the spring-loaded portal will stop flashing once the transferring of data is compete. Subsequently, program 30 executes the transferring of data from the source computer to the location on the target computer (step 264).
However, if after performing the estimate (step 252) program 30 determines that the amount of time is less than the configurable threshold value (decision 256, no branch), then the program will not display the data transfer progress indicator and will simply execute the transferring of data from the source computer to the location on the target computer (step 264). Subsequently, program 30 will determine if the transfer of data is complete. If the transferring of data is not complete (decision 268, no branch), then program 30 will again estimate an amount of time to perform the transferring of data (step 252). Otherwise, if the transferring of data is complete (decision 268, yes branch), then program 30 minimizes configurable spring-loaded portal 312 (step 272) from the open position to the closed position and the program ends.
FIGS. 3A-3H illustrate an end-user of source computer 320 utilizing data sharing program 30 to perform a drag-and-drop operation for transferring of data (e.g. a text object) from the source computer to a location on target computer 321, wherein the location on the target computer is previewable at the source computer through configurable spring-loaded portal 312. Source computer 320 and target computer 321 each have their own display, and each include their own configurable spring-loaded portal 312. In one embodiment, source computer 320 and/or target computer 321 may each only have one configurable spring-loaded portal 312, but in alternative embodiments the source computer and/or the target computer may each have more than one configurable spring-loaded portal.
In FIG. 3A, while configurable spring-loaded portal 312 is in a closed position on source computer 320, the end-user selects text object 302 utilizing mouse pointer 314 of the source computer.
In FIG. 3B the end-user drags text object 302 over configurable spring-loaded portal 312 on source computer 320 utilizing mouse pointer 314, wherein the configurable spring-loaded portal is in the closed position. However, the action by the end-user of dragging text object 302 over configurable spring-loaded portal 312 triggers program 30 to expand the configurable spring-loaded portal from the closed position to the open position.
Thus, in FIG. 3C program 30 expands configurable spring-loaded portal 312 of source computer 320 from the closed position to the open position, wherein the transferring of text object 302 is previewable through the configurable spring-loaded portal by the end-user. Specifically, configurable spring-loaded portal 312 of source computer 320 can expand from the closed position to the open position while the end-user is dragging text object 302 with mouse pointer 314 and coordinates of the mouse pointer are within a region occupied by the configurable spring-loaded portal.
FIG. 3D illustrates the appearance of mouse pointer 314 on the display of target computer 321 during the transferring of text object 302 from source computer 320 to the location on target computer 321. Specifically, on the display of target computer 321, mouse pointer 314 is highlighted and configurable spring-loaded portal 312 of the target computer can flash to indicate the transferring of text object 302 from source computer 320 to the target computer.
FIG. 3E illustrates that the location of mouse pointer 314 is controlled from source computer 320. In addition, while text object 302 is being dragged by the end-user over configurable spring-loaded portal 312 of source computer 320, program 30 continues to refresh the configurable spring-loaded portal with an updated screen snapshot image of the location on target computer 321.
FIG. 3F illustrates the end-user dropping text object 302 at the location on target computer 321. Specifically, mouse pointer 314 of source computer 320 is highlighted and viewable on the display coupled to target computer 321. After dropping text object 302 at the location on target computer 321 and the transferring of the text object is complete, configurable spring-loaded portal 312 of source computer 320 will return to the closed position.
FIG. 3G illustrates configurable spring-loaded portal 312 of source computer 320 in the closed position after utilizing mouse pointer 314 to drop text object 302 at the location on target computer 321.
FIG. 3H, illustrates that mouse pointer 314 of source computer 320 no longer appears on target computer 321 after the transferring of text object 302 is complete.
Based on the foregoing, a computer system, method, and program product for providing an efficient and intuitive way to transfer data from a source computer to a location on a target computer utilizing a drag-and-drop operation and a spring-loaded portal have been disclosed, wherein the location on the target computer is previewable at the source computer through the spring-loaded portal while the transfer of data is being performed. However, numerous modifications and substitutions can be made without deviating from the scope of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of code, which includes one or more executable instructions for implementing the specified logical functions(s). It should be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. Therefore, the present invention has been disclosed by way of example and not limitation.
