Abstract

A computer system identifies hand strokes generated while a user produces handwritten text. Based on the hand strokes, characters are identified. Based on the characters, words are identified. The words are checked for spelling, and the user is notified of any misspelled words.

First claim

What is claimed is:

1. A method for spell checking handwritten text, wherein software is provided as a service in a cloud environment to perform the method, the method comprising:
identifying, by a stroke detection module of a spell checker device including a bistable metal spring and a motion detecting sensor and encompassing, at least partially, a writing instrument, hand strokes made using the writing instrument, the spell checker device removably attached to the writing instrument, wherein the spell checker device is adaptable to removably attaching to a plurality of writing instruments of various sizes;
identifying, based on the one or more hand strokes, one or more characters;
identifying, based on the one or more characters, a word;
determining whether the word is misspelled, wherein the determination includes comparing the word to a dynamic list of words, determining that the word is not a new word, and receiving input from a second user indicating that the word is misspelled, and wherein, the dynamic list of words includes at least one word added by a user;
in response to determining the word is misspelled, notifying the user, wherein notifying the user includes displaying, via a streaming application on the spell checker device and on a liquid crystal display (LCD), the word, and displaying, on the spell checker device, at least two alternative spellings of the word;
displaying the word and at least one alternative spelling on a companion device, wherein the companion device includes an optical device worn by the user, and wherein displaying the word includes superimposing the alternative spelling over the misspelled word;
receiving information about the user;
analyzing the information to form a hand stroke profile tailored to the user, the hand stroke profile associating sets of hand strokes to characters, wherein the sets of hand strokes are generated by detecting the user's hand positions over time, and wherein associating sets of hand strokes to characters causes the spell checker device to adapt to the user's handwriting style, and wherein the sets of hand strokes are a database of hand strokes captured from a plurality of users;
responsive to determining the word is misspelled, determining one or more characters are misidentified;
identifying a correct character; and
responsive to identifying the correct character, assigning the set of hand strokes associated with the misidentified character to the correct character in the hand stroke profile.
