Data entry for personal computing devices

Abstract

In one aspect of the present invention the user can rapidly enter and search for text using a data entry system through a combination of entering one or more characters on a digitally displayed keyboard with a pointing device and using a search list to obtain a list of completion candidates. The user can activate the search list to obtain a list of completion candidates at any time while entering a partial text entry with the data entry system. When the search list is active, a list of completion candidates is displayed on a graphical user interface for the user to select from and the user can perform one of several actions. The user can deactivate the search list and return to modifying the current partial text entry and other text. The user can select one of the completion candidates in the search list and use the selected completion candidate to replace the partial text entry which the user is currently entering. When the user deactivates the interactive search list, the user can immediately continue adding to or modifying the current partial text entry being entered, and may re-invoke the search list to further search for completion candidates based on the modified partial text entry. In the second case, the selected completion candidate is used to replace the partial text entry that the user is currently entering, and the data entry system begins monitoring for a new partial text entry from the user.

Description

[0001] This application is a continuation of International Application No. PCT / CA00 / 00285 filed Mar. 15, 2000, which is designated, for the purposes of the United States of America, a continuation-in-part of U.S. patent application Ser. No. 09 / 272,700 filed Mar. 18, 1999. This application claims the benefit of the aforementioned International Application No. PCT / CA00 / 00285 and U.S. patent application Ser. No. 09 / 272,700.FIELD OF THE INVENTION [0002] The present invention relates generally to computer-assisted data entry and more particularly to a method, system, and apparatus for computer-assisted text generation and entry using a pointing device with a personal computing device, and to computer-readable media having executable instructions for supporting text generation and entry using a pointing device. BACKGROUND OF THE INVENTION [0003] The wide-spread adoption of miniaturized personal computing devices, such as hand-held devices and personal digital assistants (PDAs), has led to...

AI Technical Summary

Benefits of technology

[0010] In one embodiment, when the search list is active the user may use one of the completion candidates in the search list to initiate a further automated search to obtain a more refined list of completion candidates. In this embodiment, multi-level search lists and searching are available to help accelerate completion of a partial text entry. As a result, the user can automatically initiate an iterative search wherein a completion candidate listed in the search list is used as the new partial text entry to dynamically obtain a new list of completion candidates, which is then displayed in the search list. The automated ability to use the search list to obtain a refined list of completion candidates allows the user to quickly make good use of search results that are only partially successful. When the search list is revised with a new list of completion candidates, the user can then choose one of the completion candidates in the new list, or the user can repeat the iterative search process once again by choosing one of the completion candidates in the new list and activating a further iterative search. In addition, the user may return to keyboard entry with the last completion candidate selected by the user in the previous iteration of the search list. This latter feature provides the user with the convenience of being able to automatically and seamlessly continue entering the desired word, phrase, or character sequence using the last completion candidate selected by the user in the previous iteration of the interactive search list. Thus, the user can quickly and easily replace the user's current partial text entry with a partially successful completion candidate and continue building upon or modifying this partial completion candidate using the keyboard while at the same time allowing the user the flexibility to re-enter the search list at any time.

Problems solved by technology

While such pen-based computing is popular, especially with the increasing power of miniature computing devices, it does present challenges to a user entering data in an application running on the hand-held device.

While such data entry mechanisms are useful, they are relatively difficult to use and complex to learn and can be prone to error in the event the user deviates from the predetermined scripting style or the users traditional handwriting style.

Many on-screen keyboards have shown themselves to be less than efficient for entering text.

This “hunt-and-peck” method of typing with a single pointing device is time-consuming, especially when a user is entering large amounts of data.

Another common challenge when entering data into a personal computing device with a single pointing device such as a pen or stylus, and in particular when entering text, is that each letter making up the word or phrase must be entered manually.

Another problem in the art is that soft, or digital, keyboards have tended to be continually displayed so as to permanently consume screen space or have needed to be manually invoked and dismissed by the user.
