There is provided an image display device including a display control unit having a display combining unit that displays one or a plurality of pathological index cursors based on information relating to a pathological slide image.

Method and system for children learning one or more languages is presented. In one embodiment, a method and system comprises looking at pictures, looking at words in one or more forms, looking at texts depicting one or more relations between words, and listening to audios of words, texts to develop the reading skills in a language, in consistent with children's cognitive developments. According to another embodiment, a method and system comprises looking at pictures, reading words in one or more forms of a language, looking at the handwriting form of the word, moving a pointing device or finger following the strokes of the handwriting form, and listening to the audios of words, texts to develop the reading and writing skills in one or more languages.

Methods for providing drawing assistance to a user sketching an image include geometrically correcting adjusting user strokes to improve their placement and appearance. In particular, one or more guidance maps indicate where the user should draw lines. As a user draws a stroke, the stroke is geometrically corrected by moving the stroke toward a portion of the guidance maps corresponding to the feature of the image the user is intending to draw based feature labels. To further improve the user drawn lines, parametric adjustments are optionally made to the geometrically-corrected stroke to emphasize correctly drawn lines and de-emphasize incorrectly drawn lines.

A system and method for training correct positioning and pressure of digits on a marking instrument helps teach correct positioning and pressure of digits on a marking instrument, and a correct marking angle of the marking instrument relative to a reference plane. The system provides an electronic marking instrument having pressure sensors that detect the position and a predetermined, uniform pressure from three digits. The marking instrument further comprises tilt sensor that measures the marking angle of the marking instrument to determine whether a predetermined marking angle, between 45 to 90 degrees has been achieved. A determination of a predetermined pressure by the digits, and a predetermined marking angle of the marking instrument actuates a marking portion on the marking instrument to enable marking. However, a determination of an improper position and pressure of the digits and orientation of the marking instrument deactivates the marking portion to restrict marking.

An error detection system for automatically evaluating writing includes: an example construction apparatus to collect example sentences including various literary styles, to break up the collected example sentences in units of morphemes, and to construct the example sentences in an example-based index database (DB); and an error detection apparatus to break up an input sentence in units of morphemes, to generate one or more morpheme sequences bound in arbitrary window sizes based on one or more of morphemes of the broken-up input sentence, to search the example-based index DB for each of the generated morpheme sequences, and to detect an error according to a frequency at which said each morpheme is arranged in a corresponding morpheme sequence among morpheme sequences searched for through the example-based index DB.

Disclosed is a digital pen that tracks the user's writing and provides useful feedback based on the user's writing. In one embodiment, the pen may provide feedback when the user has written a misspelled word, invalid mathematical expression, or any noncompliant expression. The pen may also provide feedback relating to the user's handwriting. The feedback may be visual, auditory, or tactile, and may be realtime or delayed. Statistics relating to the user's performance may be tracked, uploaded to external devices, and shared with others. This allows the user and interested parties to track the user's progress over time. The disclosed pen will be useful in educational settings.
