Word-prediction software

Word prediction software can help a user during word processing by "predicting" a word the user intends to type. Predictions are based on spelling, syntax, and frequent/recent use. This prompts kids who struggle with writing to use proper spelling, grammar, and word choices, with fewer keystrokes.

Comments from readers

"I would like to know if the iPad and letter tracing applications could be considered a "legal" form of assistive technology used by a kindergartner with severe fine motor delays but age appropriate cognition. "
"This is assitive technology fro students with barrierse to learning"
"I would like to know if there are more assistive technology products that are available for students and how do parents buy these products?"
"I am very grateful for your website and all the information it offers; I do, however, believe that there needs to be more information available on grammar correction programs. Grammar correction programs built into word processors are limited and do not keep up to date with changes in literary constructs, i.e. beginning or ending a sentence with a preposition was, at one time, considered poor writing."
"In today's school and business environments, the most common means of communication is reading and writing. People that don't master those communication methods are usually left behind. 5-17% of the population suffers from dyslexia, a neurological problem that affects those peoples' ability to write and read freely. In addition, approximately 1.5 billion people are left behind due to the fact that English is their second language. The common number one writing assistive technology, the standard spellchecker, is not effective for people with dyslexia and people that use English as their second language. This failure is due to two structural limitations of all spellcheckers: 1. The fact that a spelled word needs to be very, very close to the target word in order to get corrected spelling 2. The fact that the text is checked word by word, disregarding any contextual considerations >From a technical perspective, most of the spellcheckers use a very limited editing distance, which is defined as the number of operations required to transform one word into another. For example, the words 'happy' and 'hapy' have an editing distance of 1 (one missing letter) and will, therefore be attuned successfully, but the words 'happy' and 'apy' have an editing distance of 2 and therefore will not be treated successfully. In addition, standard spellcheckers will regard the sentence 'I will be happy to meat you at 8 o'clock' as a legitimate expression, disregarding the intention of the writer, which is 'I will be happy to meet you at 8 o'clock. The word 'meat' will not appear as a misspelled word since it is found in the dictionary. For many years Natural Language Processing (NLP) researchers developed advanced models in order to analyze spelling from a contextual wording perspective, but unfortunately these models were not able to hold water in the real world. Today a company named Ghotit comes and changes it all. Ghotit's mission is to move people with writing and reading problems towards the main stream, the general population that do not have any problems with reading and writing. Ghotit's solution is an online context sensitive spellchecker which copes effectively with spelling mistakes that regular spellcheckers can't cope with, and a capability to identify misused words and offer the appropriate corrections based on a contextual analysis of the sentence. In order to further assist the user, Ghotit offers both a Text to Speech service, which enables the user to request his text to be read out aloud, and online definitions of each word, so that the user can easily select the correct candidate word. Ghotit was founded by Ofer Chermesh, a lifelong dyslectic and entrepreneur who for years had envisioned in his mind the exact assistive technology solution that would address his writing and reading hardships; and by his friend Dr. Robert Iakobashvili a high performance computing expert that undertook the challenge of translating Ofer's dream into a reality. Ghotit web site launched February 2008 after more than a year of research and development. Current testing of a corpus of dyslectic English demonstrated 90% correction success for Ghotit. This is in comparison to academic research reports that state that the best spell checkers success rate is under 35% (e.g. a recent Ph.D. study Ghotit plans in the near future to integrate Ghotit to different word and email editors such as Microsoft Office and Google Docs and to improve its context spell checker by adding grammar corrections and text enrichment capabilities. Each user will manage a personalized dictionary that can be accessed online from any computing device. Further plans include self-optimizing algorithms that optimize the context spellchecker algorithms based on specific user behavioral patterns. Ghotit plans to contribute its error-collected corpus to the academia for research purposes. For a review of Ghotit please go to SpeEdChange.

"I need help selecting a laptop for my 8th grader. His disability is in reading, writing and orgainization. He is a high functioning 13 year old boy and uses our computer at home, but a laptop will open up a world of opportunity for him in the classroom and resourse room at school. Do you have any access to reviews from users or any ideas?"
