A handwriting support device includes a half mirror; an image display surface; a writing surface, a virtual image of an image displayed on the image display surface being projected on the writing surface. In a case where a real object is inserted onto the writing surface, the image display control unit causes a non-display processed image to be displayed on the image display surface, the non-display processed image being obtained by at least a partial region, of a region of the first image corresponding to a vertically projected region of the real object on the writing surface, being subjected to non-display processing. In the handwriting support device, an image, which is a virtual image of the non-display processed image in which at least a part of an inside of the vertically projected region of the real object is non-displayed, is projected onto the writing surface.

An operating method of an interactive service platform including the steps of: communicating with a plurality of user end devices via an application software; receiving physiological measurement information of user from the user end devices via the application software; analyzing the physiological measurement information to identify a physical and mental state/lifestyle of an associated subscriber; and automatically responding content information associated with at least one associated subscriber according to requests from the user end devices.

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 computer enabled method teaching a relation of two-dimensional depictions with three-dimensional objects is provided. Users employ line drawings having sections thereon which may be colorized by the user. The colorized line drawings may then be electronically positioned upon video depictions of the three-dimensional object as a viewable guide to the user during colorization of a physical rendition of the three-dimensional object. The system may employ product packaging as the three-dimensional object to defray costs and for contests and product promotion.

One or more transparent or translucent sheets of cellophane are folded and cuts are made to create symmetric patterns and designs. The cellophane creates diffraction, refraction, interference, and reflection pattern of light that become strikingly visible when viewed under polarized light. The cellophane patterns and designs are placed on top of one another such that the holes in the overlapping sheets cause a variation in the path of light traveling through the layers of the cellophane, creating beautiful and varied optical patterns of light that change with the placement of the layers of cellophane and with variation of the angle of polarized light for a kaleidoscope effect. The cellophane is viewed against the backdrop of a blue sky to provide a source of polarized light. Placing the cellophane on glossy black cardboard brings out the prismatic colors created by light refraction and reflection.

Described herein is a system and method regarding an interactive drawing tutorial session for creating a drawing using a computer application. A digital image is processed to determine linework and shading information for a plurality of shading levels. A graphical user interface for an interactive drawing tutorial session for creating the drawing by displaying the determined linework to a user. User linework input is received for the drawing based upon the displayed linework information. Feedback is provided to the user regarding the received user linework input (e.g., regarding tilt and/or pressure of electronic stylus). For each of the plurality of shading levels, the determined shading information is displayed to the user. User shading input is received for the drawing based upon the displayed shading information. Feedback is provided to the user regarding the received user shading input (e.g., regarding tilt and/or pressure of electronic stylus).

An improved machine learning system is provided. For example, a content management server may provide a digital assessment of a user's handwriting to assess the user's knowledge of a language. The assessment may comprise adaptive technology to help determine initial questions to provide to the user as well as follow-up questions to clarify appropriate remediation content in a particular context. The content management server may also provide real-time analysis, including assessing multiple users at the same time in adjusting the assessment based on the digital input from each of these users. In some examples, the content management server may incorporate handwriting analysis methods to perform object detection and score handwriting input.
