A system for capturing, organizing, and storing handwritten notes includes a plurality of boundary markers. The boundary markers are configured to be positioned on a writing surface. The system also includes a tangible non-transitory computer readable medium encoded with instructions which, when run on a camera-equipped computing device, causes the camera-equipped computing device to execute processes. The processes include capturing an image of the writing surface with the markers thereon. The processes also include detecting the boundary markers in the captured image. Additionally, the processes include identifying a virtual boundary in the captured image based on the positions of the boundary markers. The processes then unwarp a portion of the captured image within the virtual boundary to produce an unwarped image.

A magnetic sheet includes a first sheet, a second sheet, and a number of microcapsules disposed between the first and the second sheets. Each microcapsule contains magnetic particles, clustered magnetic particles, non-magnetic particles, clustered non-magnetic particles, a suspending agent, and a solvent. The magnetic sheet is designed so that the magnetic particles reacting to a rotating magnetic line of force applied from a side of the first sheet rotate and move in a direction opposite to a direction of rotation of the magnetic line of force and aggregate near a center of the microcapsule to stay stationary.

A handwriting board is provided. The handwriting board includes a bendable support plate, a touch screen and a control module located at the bendable support plate. The touch screen and the control module are electrically connected with each other. The touch screen is configured to sense a writing operation of a stylus on a writing paper and to generate touch coordinate data of the writing operation. The control module is configured to acquire the touch coordinate data and to generate touch handwriting information according to the touch coordinate data. The handwriting board is configured to sense the writing operation of the stylus on the writing paper and to form the touch handwriting information corresponding to an actual handwriting of the stylus formed on the writing paper.

A series of devices that allow for embedding of an image as a background while also affording the user the ability to write and print on the surface, with erasable capabilities, thus providing a multifunctional product for use in numerous industries. The devices are manufactured from predominately corrugated plastic. In one embodiment a one piece, removably attachable, cabinet system and graphic display system. In an additional embodiment, a writable board, or peg board comprising a front panel and a rear panel wherein the panels are interconnected by parallel rows, or corrugations, these panels include a writable and erasable surface. The present invention relates to assemblies of corrugated systems to better serve personal, business, and educational needs.
