A system for processing a handwritten message received by a messaging app can modify playback over time of the handwritten message based on a set of rules to determine how to modify the playback. In one embodiment, graphics data (e.g. vector graphics data) that represents the handwritten message is processed using the rules to determine how to modify the playback such that the resulting playback includes at least one modification over a portion of time of the playback.

An ink file output method is provided, which includes: generating M (M is an integer of 1 or more) pieces of stroke data SD on the basis of event data generated as M input devices move, respectively; generating N (N is an integer of 1 or more and M or less) kinds of logical names LN (metadata) identifying the M number of input devices; generating a metadata block associating the M pieces of stroke data SD with the N kinds of logical names LN; and writing the M pieces of stroke data SD and the metadata block to an ink file.

Disclosure herein concerns a method that includes illuminating a user's eye with an illumination source in a head-worn display, capturing an image of the user's eye with an eye camera in the head-worn display, wherein the image includes an eye glint produced by light from the illumination source that is reflected from a surface of the user's eye, determining a size of an eye glint in the captured image, and identifying a change in focus distance for the user's eye in correspondence with a change in the size of the eye glint.

A computer-implemented method for generating feedback based on a handwritten text, comprises the steps of initializing a writing instrument to be used in a writing operation comprising a handwritten text and capturing and processing the handwritten text to generate digital text data. The method further comprises the steps of identifying at least one handwritten text attribute associated with the digital text data, comparing the at least one handwritten text attribute with predefined textual feature attributes, and generating a textual feature based on the compared at least one handwritten text attribute and predefined textual feature attributes. In addition, the method comprises the steps of modifying the digital text data using the textual feature and generating feedback to a user based on the modified digital text data.

An electronic device is provided. The electronic device includes a display, an input sensing circuit capable of acquiring a handwriting input inputted through the display, and at least one processor electrically connected to the display and the input sensing circuit, wherein the at least one processor uses the input sensing circuit to recognize written characters generated by means of the handwriting input inputted through the display, determines the slope of the recognized written characters, horizontally aligns the recognized written characters on the basis of the determined slope, and controls the display so that the recognized written characters and the horizontally aligned written characters are overlapped and displayed.

Aspects of the present invention relate presentation of digital content, in a see-through display, representing a known location in an environment proximate to a head worn computer.

There is provided an information processing apparatus including an operation unit acquiring an input operation for a message composed of at least one of text and an image, a recording control unit recording the message in accordance with the acquired input operation, and a reproduction control unit reproducing the recorded message to display the message on a display unit.

Disclosure herein concerns a method that includes illuminating a user's eye with an illumination source in a head-worn display, capturing an image of the user's eye with an eye camera in the head-worn display, wherein the image includes an eye glint produced by light from the illumination source that is reflected from a surface of the user's eye, determining a size of an eye glint in the captured image, and identifying a change in focus distance for the user's eye in correspondence with a change in the size of the eye glint.

A writing data processing device includes a processor and a memory. The memory stores computer-readable instructions that, when executed by the processor, perform the processes. The processes include acquiring stroke data describing a plurality of tracks of a writing portion on a mount portion. The processes include identifying the tracks as a group among the plurality of the tracks described by the acquired stroke data. The processes include acquiring a group region. The processes include selecting an entry frame from among at least one entry frame described by entry frame data included in paper medium data that is stored in a storage portion and is corresponding to the paper medium. The entry frame to be selected has the greatest amount of overlap with the acquired group region. The processes include moving the identified group included in the acquired group region into the selected entry frame.

An input display device includes a display unit that displays a screen for handwriting input on an input screen including a plurality of input fields, a stroke data processing unit that groups stroke data which is input to a capture screen by handwriting into stroke data representing characters to generate grouped stroke data as grouping stroke data, a character recognition unit that conducts character recognition on the grouping stroke data to convert the grouping stroke data into at least one recognized character, and a control processing unit that displays the at least one recognized character at the plurality of input fields of the input screen correlated with positions, at which handwriting input was performed, in the screen for handwriting input.
