Abstract: A system is described with a plurality of keys, five of the keys representing all of the letters of an alphabet. The five keys are arranged to form two to three rows of keys. A first row includes two of the five keys and a second row includes at least two other keys of the five keys. The keys are hard keys and/or virtual keys.

Abstract: A data entry system, having an input interface adapted to identify a plurality of user interactions. The system includes a processor adapted to associate user interactions identified by the input interface with a plurality of letters of the alphabet, such that all the letters of the alphabet are assigned to at most eight user interactions. Most of the letters are assigned to specific user interactions according to one or more features of their shape in their printed form, such that most of the letters assigned to each user interaction have the same shape feature.

Abstract: A data entry system is provided using a virtual dynamic keypad having at least four keys, wherein to four of the keys at least substantially all of the letters of a language are distributively assigned and wherein the locations of the four letter keys relating to each other are dynamically defined during the entry of text. A text entry system is also provided using a virtual keypad having at least four keys wherein to four of its keys at least substantially all of the letters of a language are distributively assigned and wherein the locations of the four letter keys relating to each other are dynamically defined based on a calibrating procedure provided by the user. A data entry system is provided using a pointing device providing different pointing directions wherein each of the pointing directions duplicates a key of a predefined virtual keypad model wherein to at least some of its keys substantially all of the letters of a language are distributively assigned.

Abstract: A data entry system includes a plurality of keys each of which has two or more symbols associated with each key and a means for receiving a second specific input from a user. A third correction key is provided, where a user enters a desired input by pressing one or more of the plurality of keys corresponding to the symbols required for the desired input and further provides a second specific input also relating to at least a portion of the desired input, such that the system produces a response to the desired input by predicting the desired input based on the symbols pressed by the user and based on the second specific input. If the produced response is different than the desired input, the user may press the correction key to scroll through additional less frequent responses from the system also matching the symbols pressed and the second specific input.

Abstract: A data input system has a keypad defining a plurality of keys. Each key contains at least one symbol of a group of symbols. The group of symbols is divided into subgroups each having at least one of alphabetical symbols, numeric symbols, and command symbols, where each subgroup is associated with at least a portion of a user's finger. A finger recognition system is in communication with at least one key, where the key has at least a first symbol from a first subgroup and at least a second symbol from a second subgroup. The finger recognition system recognizes the portion of the user's finger when the finger interacts with the key so as to select the symbol on the key, corresponding to the subgroup associated with the portion of the user's finger.

Abstract: A system for data entry is provided. The system includes a touch sensitive pad for inputting user gestures and a processor to assign a virtual keypad to the touch sensitive pad such that user gestures on the pad correspond to keys of the virtual keypad. According to one embodiment gestures on the touch sensitive pad correspond to key presses on a cellular phone type keypad.

Abstract: A data entry system including a plurality of first keys, a plurality of second keys, a display and a processor adapted to interpret a first type of user interaction with the first keys as entrance of one or more characters and to interpret a second type of interaction with the first keys as mode signals which change the meanings of at least three of the second keys.

Abstract: A computerized device comprising a first input interface adapted to identify a plurality of different first user input signals; a second input interface adapted to identify a plurality of second user input signals, and a processor configured to ambiguously correspond to each of at least one of the first input signals with the first plurality of symbols, and to ambiguously correspond actuation of each of at least one of the second input signals with a second plurality of symbols. The processor associates each of the second plurality of symbols with one of the first input signals in a manner that the second plurality of symbols corresponds to a plurality of first input signals.

Abstract: A data entry system includes a plurality of keys each of which has two or more symbols associated with each key and a means for receiving a second specific input from a user. A third correction key is provided, where a user enters a desired input by pressing one or more of the plurality of keys corresponding to the symbols required for the desired input and further provides a second specific input also relating to at least a portion of the desired input, such that the system produces a response to the desired input by predicting the desired input based on the symbols pressed by the user and based on the second specific input. If the produced response is different than the desired input, the user may press the correction key to scroll through additional less frequent responses from the system also matching the symbols pressed and the second specific input.

Abstract: A data entry system comprising a group of data symbols comprising at least one of alphabetical symbols, numeric symbols, and commands (128–136), divided into subgroups. Each subgroup is associated with at least a portion of the user's finger (102–120). The system also comprises a keypad (126) defining a plurality of keys, wherein each key contains at least one of the symbols. At least one finger recognition system (100) is configured to recognize the portion of the finger when it touches a key, and to select the subgroup symbols associated with that portion of the finger interacting with that key.

Abstract: A data entry system includes a predefined number of keys for at least inputting arbitrary characters through the keys. The data entry system uses a number of symbols having at least the letters of the alphabet of at least one language and where the symbols are assigned to the keys such that at least two of the letters are assigned to at least one of the keys. A symbol assigned to a key is inputted by providing a predefined type of interaction such as one type of pressing action on the key and providing a speech information corresponding to the symbol. The speech information is detected and analyzed based on at least one of, a user's voice and a user's lips movements. The data entry system uses a database of words of a language such that in order to enter a word of the database a user provides a combined information corresponding to the word, where the combined information includes a first and second type of information.
