Patent Application
20100005463
This invention relates generally to computing environments where users employ keyboards for text, data, document creation and any of a host of other applications, and more specifically it relates to changing the functional keyboard layout to accommodate a specific user's personal keyboard functional equivalence so that the keys on the keyboard of, say, a computer not normally used by the user, will be automatically redefined to match the user's personal preferences and then restored to their original settings when the user is done using the keyboard.
Computer users are familiar with the physical layouts of commonly employed keyboards such as the standard QWERTY or alternatively, the DVORAK layout of keys on the keyboard. However, it is also very common for a given user to establish a profile of personal keyboard functional equivalents for the meaning to be associated with individual keys such as function keys or keys with special shortcut functions.
Other personal preference changes to the keyboard are related to the language in which the user normally wishes to write or communicate or to specific programming statements that the user may frequently make while using the keyboard to create applications programs or other computer code.
Indeed, numerous software programs are available either free or for fee downloading that enable a user to customize their own keyboard preferences as evidenced by the many offerings of such software on http://www.bluechillies.com/ specifically created to allow the user to customize their keyboard functional layout. However, if the user is not using his or her own customized keyboard but is using another computer and keyboard say in another office or at another user's station, customizing that other user's keyboard might not be received with pleasure.
There are several possible solutions to this problem such as manually changing the keyboard functional layout, preferred language or shortcuts that are available to user's running Linux or Windows operating systems, but these require time and effort on the part of the user. Alternatively, the user's own keyboard functional layout preferences could be recorded on a portable data memory medium such as a flashcard or smart card or memory stick to load the user's personal preferences into the computer. Use of a smartcard for such a purpose is shown in U.S. Pat. No. 7,177,915. But this type of solution requires the special smart card or other portable device to be carried about and employed by the user whenever he or she wishes to use some computer other that the one he or she customarily uses and it requires special hardware and software at the other computer to detect and read the smartcard.
The present invention solves these problems by providing a method and system that enable a user to store his or her personal keyboard layout preferences and shortcuts in a file in a web account such as email, Google or Yahoo or any web site or service that enables a user to store securely his or her private information for access only when such user logs onto the web site. When the user visits or uses a computer other than the one he or she customarily uses and has already customized with their personal keyboard layout functional preferences, it is an easy thing to simply log on to the website or email server where the user's personal keyboard preference profile has been stored, download it via the browser to the computer being used, and pass it to the operating system of the computer via an Applications Programming Interface (API). The currently-existing keyboard functional layout of that computer can be retrieved from the operating system and sent to the website or email for temporary storage so that the original keyboard layout functions may be restored again once the user is finished using the alternate computer.
The present invention provides a method, system and program for providing a user of a computer system an easy way to automatically configure the keyboard functional layout of such computer to his or her previously established tastes in choice of keyboard layout, shortcuts, language or any other user-choice variable that may be selected for defining the functions of the keys on a typical computer keyboard. The user first establishes an on-line account such as email or other server access where the user can securely store his or her preferred keyboard functional key assignments. Then, when using a computer not already configured with the user's preferred key assignments, the user can simply log on to the email or other secure web account where his or her personal key assignment functional profile is stored, download it by using the browser in the computer, and pass the new key assignment parameters via an API to the operating system of the computer to configure the keyboard key functional assignments in accordance with his or her profile. The existing keyboard key assignment table is retrieved from the computer and sent to the on line account of the user for safekeeping while the user employs the computer for any tasks he or she desires to accomplish. The system and method of the invention then restores the originally-existing key assignments to the computer when the user logs off the computer.
The foregoing and other objects and advantages of the invention will be appreciated more fully from the following further description thereof with reference to the accompanying drawings, wherein:
The invention will now be described in detail with reference to a preferred embodiment thereof as illustrated in the Drawings mentioned above.
The invention provides a simple way for the user of a computer that has not been configured with the user's preferred keyboard functional layout to invoke an automatic process that will save the currently-existing keyboard functional layout or key function assignment table from the computer, retrieve the user's preferred key function assignments that comprise the user's preferred keyboard layout from safe storage, conveniently located in any on-line account where data may be securely stored, and install that preferred key assignment functional table to the computer's OS for use while the user employs the computer. Then, upon the user's logging off the on-line account or ending use of the computer, the originally programmed preferences from the computer are retrieved from on-line storage and restored in the computer, thus returning it to the original state in which the user found it.
As is well known, the layout of a computer or other keyboard has mechanical, visual and functional or logical aspects. The mechanical aspects relate to the placement and shapes of the various keys of the keyboard. The visual aspects relate to the arrangement of the legends or markings that appear on the keys, and the functional or logical aspects of the keyboard layout relate to the meanings to be associated with activation of the keys, the latter aspect being controlled by software in the OS of the computer.
Typically, when a keyboard key is activated, the keyboard sends signals to the computer identifying which key has been activated, such as “left-most key of home row”. The meaning to be associated with the activation of such a key is the function of a programmed key assignment table stored in the computer's OS. The table may define that such a key is the letter “a”, or that some entirely different result such as a numeral, an assigned function, or a programming shortcut is to be indicated to the computer system.
Turning to
Keyboard layout preferences may include choice of language, which itself requires numerous keys to be re-assigned to mean new characters or numbers or punctuation or emphasis characters, may include total re-location of the existing key assignments such as from QWERTY to Dvorak, and/or may include re-assignment of keys normally used for functions such as textual or programming functions, all of which may suit the personal desires of the user more effectively than the existing keyboard layout when the user first begins use of the computer system.
The process generally described above with reference to
Turning to
The process continues after establishing the new keyboard layout table in the OS by monitoring in box 36 for the user to sign off of the on-line account, signifying that he or she is finished using the computer system, or, in the alternative, monitors for logoff from the computer system by the user, signifying he or she is finished. When such an event is found, the process first retrieves the old keyboard layout table from the on-line account as shown by box 37 of
Then the process passes the old, or originally-present, keyboard layout table back to the OS as shown in box 38 and, when this is complete, the process ends at box 39.
While the process of the preferred embodiment is shown in
It is somewhat arbitrary as to whether the computer process first retrieves the old keyboard layout from the OS or loads the new keyboard layout table first, so long as the old or pre-existing keyboard layout table is preserved and passed to the browser and then on to the on line account for secure storage as described. The specific order of these steps may be changed, so long as the principle of preserving the existing functional keyboard layout or table is maintained. The preferred embodiment is written so that the OS receives the new, user-preferred keyboard layout table, retrieves and passes the old keyboard layout table to the browser and then installs the new keyboard layout for use.
Having thus described the invention with reference to a preferred embodiment thereof, it will be apparent to those of skill in this art that the invention would be implemented in any particular computer system with ease, wherefore the invention as described in the following claims is not limited to any particular computer system or to any particular programming language or technique.
