  • the present invention is related to data entry. More particularly, the present invention is directed to a data entry system with features for entering data using an improved method of prediction and key press/glide voice interaction
  • the invention also relates to a data entry system using ambiguous key presses and unambiguous key presses/handwriting-characters combined with predictive word entry system.
  • the present invention also describes different methods of correction/replacement of the words proposed by the system to provide an extremely accurate and simple data/text entry system.
  • Typical systems and methods for electronically entering characters include the use of standard keyboards such a QWERTY keyboard and the like. However, as modern electronic devices have become smaller, new methods have been developed in order to enter desired characters.
  • a second method to accommodate the entering of characters on the ever smaller devices has been to simply miniaturize the standard QWERTY keypad onto the devices.
  • miniaturized keypads are often clumsy and do not afford sufficient space between the keys, causing multiple key presses when only a single press is desired.
  • word predictive system Another method for entering text in devices is word predictive system.
  • Such systems are generally capable of entering the words available within the word database of the system. Entering other words, single letters, numbers, punctuation mark characters, etc. becomes frustrating and time consuming through such systems.
  • selecting a desired word may become frustrating because the system considers all of the words corresponding to the user's key presses.
  • voice recognition software Yet another attempt to accommodate the entering of characters on smaller electronic devices, is the use of voice recognition software. Such methods have been in use for some time, but suffer from a number of drawbacks. Most notably, voice recognition software suffers from the inability to distinguish homonyms, and often requires significant advance input for the system to recognize a particular speaker, their mannerisms and speech habits. Also, voice recognition software, in attempting to alleviate these problems, has grown large and requires a good deal of processing, not particularly suitable for the limited energy and processing capabilities of smaller electronic devices, such a mobile phones and text pagers.
  • an object of the present invention to provide an improvement over the previously disclosed data entry systems by providing additional enhanced features for predicting and disambiguation using various input means including improved keypads, prediction and voice technologies, among other devices. Furthermore, it is an object of the preset invention to provide an improved data entry prediction and key press/glide with speech (e.g. voice, lip reading) and/or other additional data entry systems helping to better/faster recognize a word through the predictive data entry systems of the invention Even further, it is object of the present invention to improve upon the correction capabilities in such data entry systems.
  • speech e.g. voice, lip reading
  • the present invention is drawn to a data entry system having a plurality of input receiving means for at least entering arbitrary characters, where each receiving means is assigned more than one character, such that a user uses the input receiving means to enter a desired input.
  • a second input receiving means for receiving a second input, where the second input is a precise character or characters from the desired input; wherein the system provides a predictive output based on input from at least said plurality of input receiving means. If the predictive output is different from the desired input and a (e.g. the first) letter of the desired input is different than the first letter of the predictive output, the user may enter a predefined correction signal to provide a precise (first) character of the desired input, such that the system may provide a second predictive output based on the previously provided input from the user and the correction signal.
  • the present invention also describes different simple methods of correction of the words proposed by the system to provide an extremely accurate and simple data/text entry system. Brief description of the drawings:
