Abstract: The present invention provides a speech recognition system combined with one or more alternate input modalities to ensure efficient and accurate text input. The speech recognition system achieves less than perfect accuracy due to limited processing power, environmental noise, and/or natural variations in speaking style. The alternate input modalities use disambiguation or recognition engines to compensate for reduced keyboards, sloppy input, and/or natural variations in writing style. The ambiguity remaining in the speech recognition process is mostly orthogonal to the ambiguity inherent in the alternate input modality, such that the combination of the two modalities resolves the recognition errors efficiently and accurately. The invention is especially well suited for mobile devices with limited space for keyboards or touch-screen input.

Abstract: There is disclosed an enhanced text entry system which uses word-level analysis to automatically correct inaccuracies in user keystroke entries on reduced keyboards such as those implemented on a touch-sensitive panel or display screen, or on mechanical keyboard systems. A method and system are defined which determine one or more alternate textual interpretations of each sequence of inputs detected within a designated auto-correcting keyboard region. The actual contact locations for the keystrokes may occur outside the boundaries of the specific keyboard key regions associated with the actual characters of the word interpretations proposed or offered for selection, where the distance from each contact location to each corresponding intended character may in general increase with the expected frequency of the intended word in the language or in a particular context.

Abstract: There is disclosed an enhanced text entry system which uses word-level analysis to correct inaccuracies automatically in user keystroke entries on reduced-size or virtual keyboards. A method and system are defined which determine one or more alternate textual interpretations of each sequence of inputs detected within a designated auto-correcting region. The actual interaction locations for the keystrokes may occur outside the boundaries of the specific keyboard key regions associated with the actual characters of the word interpretations proposed or offered for selection, where the distance from each interaction location to each corresponding intended character may in general increase with the expected frequency of the intended word in the language or in a particular context. Likewise, in a virtual keyboard system, the keys actuated may differ from the keys actually associated with the letters of the word interpretations.

Abstract: The invention provides a method of transmitting electronic messages in a computer environment. The preferred embodiment receives an electronic message addressed to a telephone number and determines an instant message identifier associated with the telephone number. In response to the determination that an instant message identifier associates with the telephone number, it is further determined whether an instant message receiver is available to receive messages addressed to the instant message identifier. In response to a determination that an instant message receiver is available to receive instant messages addressed to the instant message identifier, the electronic message is forwarded as an instant message addressed to the instant message identifier.

Abstract: A selective input system and associated method is provided which tracks the motion of a pointing device over a region or area. The pointing device can be a touchpad, a mouse, a pen, or any device capable of providing two or three-dimensional location. The region or area is preferably augmented with a printed or actual keyboard/pad. Alternatively, a representation of the location of the pointing device over a virtual keyboard/pad can be dynamically shown on an associated display. The system identifies selections of items or characters by detecting parameters of motion of the pointing device, such as length of motion, a change in direction, a change in velocity, and or a lack of motion at locations that correspond to features on the keyboard/pad. The input system is preferably coupled to a text disambiguation system such as a T9® or Sloppytype™ system, to improve the accuracy and usability of the input system.

Abstract: A method, system and computer program product for instant message communication in a wireless and non-wireless environment. The invented system includes an apparatus that facilitates conversation with individuals not included in the user's buddy group, non-buddies. The system includes at least one additional routing code reserved for conversing with non-buddies. The first time during a user session that the system receives a message originating from or destined for a non-buddy, before routing the message, the non-buddy's personal identifier is associated with one of the reserved routing codes. The mobile user can then reply to the message using the same automated ‘reply’ function available for replies to buddies. The non-buddy routing code assignment is only for the duration of a user session. When the mobile user signs off from the system, the routing code becomes available for reassignment.
