  • Patent number: 7075520
    Abstract: Multidirectional keys of a reduced keypad are used to disambiguate between multiple symbols associated with a single key. For example, pressing a key identifies a collection of two or more symbols associated with the key and subsequently rocking the key selects one of the two or more symbols as unambiguously identified by the user.

  • Patent number: 6955602
    Abstract: A user composes a message within a video game paradigm by hitting targets in the video game environment which are associated with message component candidates such as letters, words, and phrases. Each of the message component candidate has a relative likelihood of selection predicted according to language usage in general and specifically of the user and according to the context of any portion of the message already composed. Message component candidates which are more likely to be selected by the user are associated with targets or other objectives of the video game environment which are more easily achieved. For example, more likely message components are associated more frequently and more centrally located and slower moving targets.

  • Patent number: 6956968
    Abstract: A computer-implemented method for encoding a handwritten stroke set, each of the handwritten stroke set being representative of a constituent stroke of an ideographic character, to obtain an encoded input sequence. The method includes ascertaining a shape of a first stroke of the handwritten stroke set and ascertaining one of a location information and a size information pertaining to the first stroke. The method further includes assigning a first code to the encoded input sequence responsive to a determination of the shape of the first stroke and a determination of the one of the location information and the size information of the first stroke. The first code is predefined to represent the shape of the first stroke and the one of the location information and the size information of the first stroke. The first code is sufficiently unique to distinguish the first code from other codes representing other permutations of shape and the one of the location information and the size information of the first stroke.

  • Patent number: 6864809
    Abstract: Consonant jamos of the Korean language are grouped according to appearance and each group is associated with a respective key of a reduced keypad. Vowel jamos are specified by the user using a number of keys reserved for vowels and each of which represents a respective category of strokes by which the vowel jamo would normally be written.

  • Patent number: 6801659
    Abstract: Beginning with the first letter or stroke, this invention uses the relative frequency of the sequential groups of letters or strokes from which individual words or characters are gradually built in order to provide a better way of computer indexing languages for easier and more efficient access to both the frequently used words or characters and the less-frequently used. This makes possible a system of text input that is both more efficient and more intuitive than utilizing just word or character frequency, an input approach which eliminates typing transpositions, reduces word-spelling errors or character-stroke-order uncertainty, and provides an alternative to a standard keyboard which is especially helpful with wireless phones and hand-held computers, and similar devices lacking standard keyboards. This invention can make words and characters quite accessible in an intuitive way without requiring any direct input of words or letters, strokes or characters.

  • Publication number: 20030023426
    Abstract: Japanese kanji-kana words intended to be entered by a user are predicted from relative few key presses, each single key press indicating a group kana syllables of the fifty sounds table. Text input logic collects all known words which include any syllables of the groups specified in the order specified and sorts the words by relative frequency to predict which word the user is intending to enter. All known words which match the same consonant pattern are collected and those most frequently used are presented at the top of the list from which the user can select the intended word. Predicted word selections are presented to the user in kanji-kana form such that kana-kanji conversion is unnecessary.
