System and method for continuous stroke word-based text input

Abstract: A method and system (2100) for continuous stroke word-based text input, having a virtual keyboard (2104) appearing on a touch sensitive screen (2102). The present invention allows a user to use the virtual keyboard to quickly enter words by drawing a continuous line that passes through or near the keys of each letter in a word in sequence without lifting the stylus. The user traces an input pattern (2200) for a word by contacting the virtual keyboard on or near the key of the first letter of the word, then tracing through each letter in sequence, lifting the stylus from the touch sensitive screen upon reaching the last letter. The present invention then analyzes each input pattern and presents a list of one or more possible words based on the input pattern, for selection by the user.

Dynamically located onscreen keyboard

Abstract: A touch-sensitive display surface having touch-capacitive and vibration sensors This surface allows the user to rest their fingers on the keys of an onscreen keyboard and type as they would on a regular keyboard As the user places their fingers on the touch screen, the system relocates the onscreen keyboard to the location where the fingers are resting The touch sensors report the signal strength level of each key touched to a processor, but no keystroke is issued by the processor until a corresponding "tap" (ie, vibration) is detected When a tap is detected, the processor references the status of the touch capacitance sensors before, during, and/or immediately after the moment in time the tap occurred The size, position, and orientation of the onscreen keyboard keys are dynamically set as determined by the user initiating a home-row definition event by resting their fingers momentarily on a virtual home-row

Systems and methods for detecting a press on a touch-sensitive surface

Abstract: Systems and methods that allow the user to rest their fingers on a touch-sensitive surface and make selections on that surface with a pressing action. Touch capacitance sensors that typically provide X and Y location data associated with a user's touch are also used to discern finger pressure in the Z direction. This allows the user to make an actuation on the touch screen by simply pressing harder at a location where they may already be resting their finger(s).

Cleanable touch and tap-sensitive keyboard

Abstract: A touch sensitive surface having touch-capacitive and vibration sensors. This surface allows the user to rest their fingers on the keys and type as they would on a regular keyboard. As the user places their fingers on the keys, the touch capacitive sensors (one per key) report the signal strength level of each key touched to a processor, but no keystroke is issued by the processor until a corresponding “tap” (ie. vibration) is detected. When a tap is detected, the processor references the status of the touch capacitance sensors before, during, and/or immediately after the moment in time the tap occurred.

As the user places their fingers on the keys, the touch capacitive sensors (one per key) report the signal strength level of each key touched to a processor, but no keystroke is issued by the processor until a corresponding 'tap' (ie.vibration) is detected. When a tap is detected, the processor references the status of the touch capacitance sensors before, during, and/or immediately after the moment in time the tap occurred.

Gestures for touch sensitive input devices

Abstract: Methods and systems for processing touch inputs are disclosed. The invention in one respect includes reading data from a multipoint sensing device such as a multipoint touch screen where the data pertains to touch input with respect to the multipoint sensing device, and identifying at least one multipoint gesture based on the data from the multipoint sensing device.

Display screen or portion thereof with graphical user interface

Abstract: Newness and distinctiveness is claimed in the features of ornamentation as shown inside the broken line circle in the accompanying representation.

Intelligent Automated Assistant

Abstract: An intelligent automated assistant system engages with the user in an integrated, conversational manner using natural language dialog, and invokes external services when appropriate to obtain information or perform various actions. The system can be implemented using any of a number of different platforms, such as the web, email, smartphone, and the like, or any combination thereof. In one embodiment, the system is based on sets of interrelated domains and tasks, and employs additional functionally powered by external services with which the system can interact.

Mode-based graphical user interfaces for touch sensitive input devices

Abstract: A user interface method is disclosed. The method includes detecting a touch and then determining a user interface mode when a touch is detected. The method further includes activating one or more GUI elements based on the user interface mode and in response to the detected touch.

Proximity detector in handheld device

Abstract: Proximity based systems and methods that are implemented on an electronic device are disclosed. The method includes sensing an object spaced away and in close proximity to the electronic device. The method also includes performing an action in the electronic device when an object is sensed.
