A display device includes a circuitry configured to perform a search for a plurality of image candidates in an image transformation dictionary part, based on handwritten data, and a display configured to display the plurality of image candidates obtained by the search. At least a portion of the plurality of image candidates displayed on the display represents a different person or an object.

An object is to provide a display apparatus capable of identifying handwritten data drawn by a particular display apparatus. A display apparatus for displaying data, in which indication of handwritten input originated data drawn by the display apparatus is recorded in association with the handwritten data.

An object management system includes an identifier generation device and an object collation device. The identifier generation device includes a generation unit that forms an ink layer on a target object, an imaging unit that images an uneven pattern on a surface of the ink layer, and a registration unit that registers the imaged result in a storage unit. The object collation device includes an imaging unit that images the uneven pattern on the surface of the ink layer formed on the target object, and a recognizing unit that recognizes the target object based on an image of the uneven pattern obtained by imaging.

Examples described herein generally relate to rendering grid-aligned digital ink on a display of a computing device. In an example, the computing device determines grid pattern data associated with a grid pattern displayed on the display and a velocity of the input. Based the grid line pattern data and the velocity, the computing device may render digital ink that is traced along one or more grid lines of the grid pattern.

A handwriting processing method, a touch display device, a computer device, and a storage medium are provided. The handwriting processing method includes: determining, according to a sample point in a writing track that is input by a user by means of a touch display, a group of track points and a related parameter of each track point, the related parameter including a coordinate parameter and a time parameter; determining, according to the related parameter of each track point, a start position, an end position, and a type of a stroke contained in the writing track, where the type of the stroke includes one of a horizontal stroke, a vertical stroke, a left-falling stroke, a right-falling stroke or a lifting stroke; and determining, according to the type of the stroke, a shape of the start position of the stroke.

A method for creating handwriting content is provided. The method includes displaying handwriting letters being input, extracting at least one candidate handwriting word stored in advance in response to the input handwriting letters, displaying the extracted at least one candidate handwriting word, and replacing the input handwriting letters with a candidate handwriting word selected from among the displayed at least one candidate handwriting word.

A writing device includes a liquid crystal layer including reflective cholesteric liquid crystal material. There are electrically conductive layers between which the liquid crystal layer is disposed. At least one of the electrically conductive layers includes at least two conductive sections. There is a front substrate that is flexible and a back substrate between which the electrically conductive layers and the liquid crystal layer are disposed. Neither the front substrate nor the back substrate includes separated sections. Application of pressure to the front substrate changes a reflectivity of a portion of the cholesteric liquid crystal material to form an image. In one aspect, there is electronic erase circuitry including at least one actuator that independently applies an erase voltage waveform to each of at least two of the conductive sections. In another aspect the electronic erase circuitry includes at least one actuator that independently applies an erase voltage waveform to each of the conductive sections, and that applies erase voltage waveforms to at least two of the conductive sections in combination.

An electronic device, when in a first tilted state, displays a content page in a sketch mode, which includes displaying a zoomed view of a portion of the content page, and configuring the zoomed view of the portion of the content page to accept user inputs modifying content in the first portion of the content page. While displaying the content page in the sketch mode, the device detects that it is tilted from the first tilted state to a distinct second tilted state, and in response, displays the content page in an overview mode, which includes zooming out to display an overview of the content page. Optionally, displaying the content page in the overview mode includes displaying an input position indicator over the overview of the content page to indicate the portion of the content page previously displayed in the zoomed view.

A touch driving device and a touch movement track identification method are provided. The touch driving device includes a touch sensing circuit and a touch control circuit. The touch sensing circuit receives touch sensing signals from a touch sensor array when a touch display screen is operated in a display power saving mode, and generates digital touch sensing data according to the touch sensing signals. The touch control circuit periodically generates touch coordinates according to the digital touch sensing data, identifies whether an input symbol corresponding to a touch movement track formed by the touch coordinates generated consecutively matches a preconfigured symbol, and outputs a matching result to a core processing unit of the electronic device. The touch coordinates are generated when the orientation of the input symbol drawn on the touch display screen is not the same as a screen orientation of the touch display screen.

A writing system that includes a reusable notebook including a sheet having a working surface. The working surface includes a printed code and an operative control. The writing system includes a writing instrument configured to capture images of the printed code and a computing device configured to communicate with the reusable notebook and/or the writing instrument. The sheet includes a surface coating over the working surface configured so that a writing material of the writing instrument can be removed by applying a dry ancillary device.
