They develop a new model of interactive whiteboard without shadow

Educational technology expert José Juan Nimo Silva has invented a new screen surface method for ICT in classrooms. The innovative nature of this technological product is given because it avoids the shadows produced by the person who is using it..

The world of teaching has a new educational ICT tool, a new model of shadowless digital whiteboard that has been specially designed to be used interchangeably as a classic whiteboard and as a screen for projection and rear projection. Designed by José Juan Nimo Silva, This innovative projection surface allows triple use: as a conventional projection screen, whiteboard for use with markers and interactive whiteboard with infrared or ultrasound devices, oriented to the teaching and disability sectors.

The invention allows a multipurpose use for writing and annotations like any other whiteboard., and also, in a special way, solves the problem that arises when used with a video projector and especially when used together with over-the-air PDI (infrared, ultrasound, or others) given that, in this use, totally eliminates shadow and glare.

The object of the invention is to provide a system that allows triple use: First of all, that can be used in a classic way, allowing the user to work with non-permanent markers from in front of the whiteboard. In second place, The whiteboard allows use to project images with a video projector, which can be placed in front of or behind the board. Finally, in the event that the user simultaneously uses the whiteboard object of the invention, together with a video projector located behind the blackboard and some over-the-air PDI system (infrared, ultrasound, or others), is achieved, besides, avoid shadows and glare caused by the video projector lamp, as the user is in front of the screen and the video projector behind.

The multipurpose board allows you to adopt any position in front of the board, even if the user is a person with severe disabilities or lack of mobility or a young child. For this, and more specifically, The device is made from two glass sheets joined together and between them a polyvinyl or translucent plastic film. The set is completed with an aluminum frame that gives strength to the set.. This aluminum frame includes drills in different sizes, to fasten the assembly to a pair of pedestals by means of a pin with a fixed head and wing nut, all this so that a single person can assemble and disassemble the whole.

The pedestals can optionally be equipped with wheels, with brake or not, so that the device does not move once it is used. These pedestals, They are provided with a series of holes that, together with the holes in the frame mentioned above, allow height adjustment, providing the set with the necessary rigidity.

The aforementioned set can be made to measure and can be used in projection format 4:3 or panoramic 16:9, so the video projector, whatever type it is, will be placed behind the board, projecting the images on it and, given the translucent nature of polyvinyl film, The projected images can be viewed by the audience in the room from the opposite side of the blackboard.. So, the teacher or user, when making notes, a comment or explanation about any of the projected images, can approach the blackboard without problems, without projecting shadows on it that hinder the visibility of the images, icons or buttons, This board can be used together with the use of non-permanent markers., as well as a conventional whiteboard when the video projector is turned off.
