Document authoring that involves illustrating pen input in an authoring environment is herein improved to provide greater control of colors and patterns for representing the pen input in a graphical user interface. Colors and patterns are provided as effects that are applied to the illustrated pen input so that multiple textures or colors may be applied to the illustrated pen input without requiring the user to manually signal a switch in texture or colors or using multiple objects to represent the pen input. In various aspects, effects may be layered on top of each other, and the effects may be stretched or tiled depending on the size of the illustrated pen input.

The present disclosure provides systems and methods for text entry through handwritten shorthand stroke patterns. One example computer-implemented method includes receiving, by a mobile computing device, data descriptive of an input stroke pattern entered by a user. The input stroke pattern includes one or more strokes that approximate a non-linguistic symbol. The method includes identifying, by the mobile computing devices, one of a plurality of shorthand stroke patterns as a matched shorthand pattern to which the input stroke pattern corresponds. The plurality of shorthand stroke patterns have been previously defined by the user. A plurality of output text strings are respectively associated with the plurality of shorthand stroke patterns. The method further includes, in response to identifying the matched shorthand pattern, entering, by the mobile computing device, the output text string associated with the matched shorthand pattern into a text entry field.

Techniques for ink in an electronic document are described. According to various implementations, techniques described herein provide a rich set of tools which allow a user to markup an electronic document such as a web page, not only in static 2D where the user writes on top of a document, but in dynamic 3D. In addition, when adding 3D elements to an electronic document, the 3D elements are added based on awareness of the content of the electronic document and can adapt its content in relationship to the document.

Techniques for ink input for browser navigation are described. Generally, ink refers to freehand input to a touch-sensing functionality and/or a functionality for sensing touchless gestures, which is interpreted as digital ink. According to various embodiments, ink input for browser navigation provides a seamless integration of an ink input canvas with a web browser graphical user interface (“GUI”) to enable intuitive input of network addresses (e.g., web addresses) via ink input.

The disclosure relates to a character input method and system, which may include a digital device including a touchscreen that has a recognition area and an insertion area. The method and system may include hardware and/or operations for: scrolling a string of characters that are displayed in the recognition area so as to select a position between a first character and a second character; detecting input strokes that are entered manually in the insertion area; performing handwriting recognition to convert the detected input strokes into recognised characters; inserting, at the position within the string of characters, the recognised characters; and scrolling the string of characters in the recognition area so as to display, in the recognition area, the recognised characters that were inserted into the string of characters.

An image processing device includes a handwriting renderer, an image renderer, an external image renderer, a serializer, a creator, a recognizer, and a concatenation unit. The handwriting renderer is configured to render a stroke on a first layer. The image renderer is configured to render an image on a second layer lower than the first layer. The external image renderer is configured to render an external image on a third layer lower than the second layer. The serializer is configured to convert the stroke rendered on the first layer and the images rendered on the second and third layers into text data. The creator is configured to create document data corresponding to one page based on the text data. The recognizer is configured to acquire a character string from the stroke. The concatenation unit is configured to concatenate adjacent characters on the string with an unnecessary space therebetween being deleted.

The disclosure relates to a character input method and system, which may include a digital device including an input surface and an output surface. The method and system may include or perform operations including: displaying a character string using a recognition area and an insertion area of the output surface; selecting a position within the character string; displaying, in the recognition area, a part of the string ending with a first character while masking, in the insertion area, a part of the string starting with a second, succeeding character; detecting an input stroke entered manually in the insertion area; performing handwriting recognition; inserting, at the position within the string of characters, a recognised character(s); and scrolling the string in the recognition area so as to display, in the recognition area, the recognised character(s) that were inserted into the string of characters.

A computing device may include one or more dynamically configurable user input devices. In one example, a triggering event, such as, for example, a user input at a user interface of the computing device, may be detected in connection with an application running on the computing device. In response to the detected triggering event, individual elements of the user interface, such as, for example, keys of a keyboard, may be configured, and/or re-configured, to correspond to the input received and/or the application running on the computing device.

A collaboration system that facilitates a collaboration session with a first participant and a second participant is provided. The collaboration system varies a response to input based on the participant who provides the input. The collaboration system may receive input data from a participant interacting with a shared surface. When the input data is received from the first participant, the collaboration system generates first output data that may be a modification of the first input data that is based at least on first customization information associated with the first participant and displays the first output data. When the input data is received from the second participant, the collaboration system generates second output data that may be a modification of the second input data that is based at least on second customization information associated with the second participant and displays the second output data.

Disclosed is a non-transitory computer-readable recording medium having stored therein a message information generating program, which when processed by one or more processors, causes a computer to execute a process. The process includes acquiring first information having both a character string input by handwriting and a character color related to the character string input by the handwriting, specifying a form of the character string based on the acquired first information, specifying an address associated with the specified form by referring to a storage configured to store an address of a message destination in association with a form of a character string, and generating message information with the specified address as a destination, the message information including second information corresponding to the character string.
