A rewritable tablet book includes a front cover, a back cover, and a spine connecting the back cover to the front cover. The rewritable tablet book includes a rewritable surface that extends across an inside surface of the front cover, the spine, and the back cover. The rewritable tablet book also includes a fastener. The fastener joins the front cover to the back cover in a closed position to hold a marker in a hollow region defined by the rewritable surface and the spine. The marker is locked in the hollow region.

A substrate usable with a double-side adhesive strip to suspend the substrate to a wall surface. The substrate can have one or more access holes located within an outer perimeter of the substrate. Each access hole has an inner perimeter inwardly of the outer perimeter that is sized and shaped to allow a tab of the double-sided adhesive strip to be extracted through the inner perimeter, after the substrate is suspended on the wall surface. Various articles can attach to the suspended substrate, such as through magnetic attachment, a hook, or a shelf.

An image projector device includes a projection optical unit through which an image is projected and displayed, a recognition unit that recognizes a user's action related to processing of the image, and a control unit that generates and/or edits a drawing image based on the user's action recognized by the recognition unit and projects and displays the drawing image being generated and/or edited as a projected, displayed image through the projection optical unit.

The present invention provides a cognitive-kinesthetic device and method which enhances, facilitates and accelerates cognitive development and learning in school-age children by coupling the learning process with movement, referred to as kinesthetic learning. The device and method is contemplated for use in school-age children ranging in age from four to twelve years old. Regardless of the age of the children, the invention provides that playing the physically active cognitive-kinesthetic game will enhance, facilitate and accelerate cognitive development and learning in school-age children, such as reading, verbal fluency, math, science, spatial relationships and other fields of knowledge, while at the same time providing a fun and exciting experience. In addition, the coupling of movement with the learning process provides a calming effect to school-age children so that they are able to pay better attention during the learning process.

Systems and methods provide a user with the ability to mark a surface, easily remove the marking, and remark the same surface. The systems and methods include a marking implement and a mark-receiving surface. When the mark-receiving surface is marked, the resulting mark dries relatively quickly, tends not to smudge, and can be wiped from the surface easily, efficiently and effectively without lasting effect to the mark-receiving surface, which then is available to be marked again.

The disclosure discloses a method for erasing a writing path on an infrared electronic white board, the method including: adding data points to a writing path to obtain a complete writing path in which the distance between any two adjacent data points is no more than an erasing distance corresponding to a selected erasing mode; determining an erasing area according to an input erasing path and the erasing mode; and erasing those data points on the complete writing path, which lie in the erasing area.

A garment having an outer surface not designed for writing has at least one rewritable area comprising a layer of rewritable material deposited directly onto a selected region of the outer surface. One or more permanent artworks may be deposited onto the garment prior to deposit of the rewritable layer, which may be contiguous or non-contiguous. A stencil is provided for allowing a user to write on rewritable areas while protecting adjacent areas of the garment. In one method for forming the rewritable area, a first portion of a permanent artwork and a second portion of the permanent artwork are successively deposited on the garment, followed by curing the permanent artwork and depositing a rewritable area on the garment.
