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.

A system, method and computer program product to train a user to reproduce a reference motion with a haptic feedback system having one or more sensors. The method includes receiving a user-selection of a reference motion pattern, selected from a plurality of motion patterns each of which is machine-interpretable as a time-ordered sequence of reference datasets. The sequence corresponds to a respective reference motion. The method includes capturing a user motion of a user attempting to reproduce the reference motion corresponding to the selected, reference motion pattern. This is accomplished by sampling, via the haptic feedback system, sensor values obtained from the one or more sensors, to obtain appraisal datasets that are representative of the captured user motion. A real-time haptic feedback is provided to the user while capturing the user motion based on comparisons between the appraisal datasets obtained and the reference datasets of the selected, reference motion pattern.

A training pen for writing has a housing, a pen cap releasably attached to the housing, a retractable ink cartridge with a writing tip extending within an inner cavity of the housing and the cap, and three flexible, arcuate tabs extending from a lower end of the housing. The cap has six sides with side openings defined in alternating sides of the cap and a lower aperture defined at a lower end of the cap. The tabs extend through the side openings when not in use. A user can push the writing tip through the lower aperture by simultaneously depressing all of the tabs into grooves defined within the surface of the cap. Release of the tabs repositions the writing tip within the cap. Use of the pen can train a user io to properly grasp a writing utensil.

A method for facilitating handwriting practice includes: generating handwriting strokes in response to user input of user-writing strokes; generating an input image that includes the handwriting strokes, and that has a shape similar to a shape of a standard image associated with a standard word character; scaling the input image to generate a scaled image with a size that is the same as a size the standard image; overlapping the standard image and the scaled image; comparing an n.sup.th handwriting stroke in the scaled image with an n.sup.th standard stroke in a standard order of the standard word character; and when the n.sup.th handwriting stroke does not correspond in position to the n.sup.th standard stroke, displaying a notification of a stroke order error.

The present application relates to an electronic drawing board, a remote teaching drawing board, a drawing simulation method and apparatus. The electronic drawing board includes: a pressure touch sensing screen configured to sense a contact of a brush with the screen and display a stroke according to a thickness, direction, color, and gradation effect of the stroke; and a drawing simulation processor configured to determine the thickness of the stroke from a contact duration of the brush with the screen when the brush is wielded on the screen, determine the color of the stroke from a type and amount of a pigment taken up by the brush and the contact duration, and determine a gradation speed of the stroke from an amount of moisture contained in the brush, and determine a gradation area of the stroke from the contact duration.
