  • Patent number: 9665275
    Abstract: A technique is presented for fast input of multi-character compound consonants and vowels on a touch computing device. The technique provides for fast input of multi-character compound consonants and vowels by enabling a user to touch an initial character on a first layout of characters, then slide his/her finger in different directions and/or different distances according to a second layout of characters. The second layout of characters can be based on the first touched character and therefore can have a limited set of characters, e.g., fewer characters in comparison to the first layout of characters. A syllable formed after input of both a consonant and a vowel, represented as one character set, e.g., in the Roman alphabet, can then be transliterated into another language, e.g., Chinese.

  • Patent number: 9442902
    Abstract: A computer-implemented technique includes receiving a first input from a user at a user device, the first input including a first word of a first alphabet-based language, which is a transliteration of a non-alphabet-based language, which is one of a logogram-based language and a syllabogram-based language. The technique then compares the first words to pluralities of potential translated words from one or more datastores associated with a second alphabet-based language and the logogram-based or syllabogram-based languages. The technique may then generate a probability score for each of the pluralities of potential translated words, the probability score indicating a likelihood of an appropriate translation. The techniques may then provide the user with some or all of the pluralities of potential translated words and the user may select an appropriate translated word to obtain a selected word, which may then be displayed via a display of the user device.
