Optimal character arrangements for ambiguous keyboards.
Many persons with disabilities lack the fine motor coordination necessary to operate traditional keyboards. For these individuals, ambiguous (or reduced) keyboards offer an alternative access method. By placing multiple characters on each key, the size and accessibility of the individual keys can be enhanced without requiring a larger keyboard. Using statistical disambiguation algorithms to aut...
متن کاملDomain–specific Disambiguation for Typing with Ambiguous Keyboards
In this paper, we investigate whether and how domain–specific corpora increase precision of word disambiguation for typing on an ambiguous keyboard. Basically, the disambiguation for our ambiguous keyboard with three letter keys is based on language–specific word frequencies of the lexicon CELEX (in this study English and German is dealt with). The more specific frequency information is extract...
متن کاملAn Evaluation Study of Two–Button Scanning with Ambiguous Keyboards
In the communication using Augmentative and Alternative Communication (AAC) aids, scanning volunteers an effective method to users who can operate at most three buttons. In this paper, we investigate scanning with ambiguous keyboards. Using an ambiguous keyboard means that words are entered by pressing the corresponding ambiguous key once for each letter. The user disambiguates the typed code b...
متن کاملTopic– and Author–Specific Suggestion Lists for Typing with Ambiguous Keyboards∗
In this paper, we investigate whether and how topic– and author–specific corpora in English and German increase precision of word disambiguation for typing on an ambiguous keyboard in five domains split into 61 topics and 18 authors. In general we could not always reach a better performance imposing the more specific suggestions. The author–specific language models improved the disambiguation p...
متن کاملComparison Among Ambiguous Virtual Keyboards For People With Severe Motor Disabilities
This paper presents an exhaustive study on the different topologies of ambiguous soft keyboards, analyzing the text entry average time per character and the average number of user inputs necessary for its creation. Various topologies and design criteria are investigated. In addition, an analytical model is also proposed. This model allows one to compare among different topologies and estimate t...
