A Tibetan input method and system relates to a character input method having an input module, including 47 input keys and used for inputting Tibetan characters; a keyboard definition module, including a plurality of storage units, each storage unit corresponding to one input key, and stores one or more Tibetan characters; when each storage unit stores a plurality of Tibetan characters, a preset ambiguous layout rule is satisfied; a Tibetan font, used for storing pre-combined Tibetan characters; and a processing device, which is respectively connected with the input module, the keyboard definition module and the Tibetan font, and is used for obtaining initial Tibetan characters corresponding to the input keys according to the keyboard definition module when the user inputs the Tibetan characters through the input keys, determining a target pre-combined Tibetan character according to the initial Tibetan characters and the Tibetan font, and outputting the target pre-combined Tibetan character.

An input method based on visual recognition, performed at a processor, includes: obtaining frames of gesture images; recognizing a size and a position of a hand feature in each frame; determining whether a variation amount in the size of the hand feature in the frame as compared to a preset calibration size is less than a preset threshold value; causing a position of the hand feature in the frame to be stored as a handwriting point; obtaining at least one stroke trace, according to handwriting points stored, each including handwriting points stored in sequence according to positions of hand features in at least two consecutive frames; and recognizing the at least one stroke trace and obtaining a target object corresponding to the at least one stroke trace.

The present disclosure relates to user interfaces for receiving handwriting input, accessing predictive text candidates, and accessing keyboards.

An information processing apparatus includes a processor configured to acquire (i) an image including characters and (ii) a character-recognition result obtained by applying character recognition on the image, and display, to a viewer of the character-recognition result, each character in the image and a recognized character corresponding to the character in a uniform size and at positions adjusted to indicate correspondence between the character and the recognized character.

A Latin character conversion apparatus includes a code associator that associates each of a plurality of character keys assigned with Latin characters among a plurality of keys included in a keyboard with any of a plurality of character codes established by a character encoding scheme of the Unicode Standard, a character associator that associates the character code with a relevant code being another character code, a code converter that, in response to an instruction by a user that instructs any of the plurality of character keys, determines the character code associated with the instructed character key as a conversion candidate, and a character converter that, in response to an instruction by the user that instructs the character key serving also as a conversion key of the plurality of character keys with the conversion candidate determined, converts the conversion candidate into the relevant code associated with the conversion candidate.

A text input method and a terminal are provided. The method includes: displaying a text editing interface when a trigger operation for triggering text input is detected, where the text editing interface includes: input operation areas of at least two input methods and text display areas for displaying text input by using the input methods; and keeping displaying the input operation areas of the at least two input methods on the currently displayed text editing interface when a switching operation for switching from one of the currently used at least two input methods to another input method is detected on the currently displayed text editing interface.

Provided is a display apparatus for displaying an operation menu associated with a data processing performed on handwritten data, wherein the operation menu includes information related to the data processing according to a display position of the operation menu.

A tactile sensation presentation device includes a display unit that displays plural images on a display screen, an operating portion including an operation surface on which a touch operation is performed to select one of the plural images displayed on the display unit, a vibration presentation unit that presents tactile sensation by vibrating the operation surface according to the touch operation, and a control unit that extracts at least one candidate image, which has a probability of being selected next after a selected image selected on the operation surface, from the plural images displayed on the display screen, predicts a next selected image to be selected next from the candidate image(s) based on a trajectory, on the display screen, of a tracing operation as the touch operation performed on the operation surface, and presents tactile sensation by the vibration presentation unit when reaching the next selected image.

A character input device may include a character input unit, an operation detector, an input trajectory measuring unit, and a character switching unit. The character input unit receives a character input operation performed using flick input. The operation detector detects the character input operation received by the character input unit. The input trajectory measuring unit measures a length of an input trajectory from a start position to an end position of the character input operation detected by the operation detector. The character switching unit switches characters regularly from a first character corresponding to the start position of the character input operation in accordance with the length of the input trajectory to obtain a second character.

The present application provides a character input method and apparatus, an electronic device and a medium. The method includes: acquiring and displaying at least one input stroke; retrieving and displaying candidate components containing the at least one input stroke; in response to a component selection instruction to select a target component from the candidate components, displaying the target component and at least one position selection button for selecting a position of the target component; in response to a position selection instruction to select the position of the target component, acquiring a target position corresponding to the position selection instruction; retrieving and displaying candidate characters with the target component at the target position; and in response to a character selection instruction to select a target character from the candidate characters, acquiring the target character.
