Reflective reading field of vision splitter

Abstract

The invention relates to a reflective reading field of vision splitter, which is composed of a rectangular colorless transparent plastic flat plate and characterized in that the flat plate is internally provided with a light reflecting layer which is arranged in an inclined manner, the upper right corner of the flat plate extends towards the upper side and the lower side so as to form two photoelectric circuit, and each photoelectric circuit comprises such structures as a battery, an electric wire, a positive electrode, a negative electrode, a sliding chute, sliding blocks and light sources; the sliding chute is provided with two concave grooves in which the positive electrode and the negative electrode are buried respectively, the light source is installed on the sliding block, the bottom part of the sliding block is provided with two bulges, the bulges are provided with metal pieces respectively, and the bulges are embedded in the two concave grooves of the sliding chute respectively, the light source takes electricity from the positive electrode and the negative electrode, which are buried in the concave grooves of the sliding chute, through the metal pieces, the light source reflects parallel light to the internal part of the flat plate after being turned on, a series of reflected light spots are generated through the reflecting layer so as to form a light spot connection line, and the light spot connection line acts as a field of vision splitting line. The number of the sliding blocks and the number of the light sources ensure the maximum application quantity of the splitting lines, when a very small number of splitting lines are required, the redundant sliding blocks and light sources slide to an insulator at a starting point of each photoelectric circuit, and the circuits and the light sources are turned off, thereby avoiding generation of redundant light spot connection lines, being simple and convenient in use, and feeling novel and interesting.

Description

technical field [0001] The invention relates to a visual field segmentation tool used in speed reading training. Background technique [0002] The speed of reading depends on the size of the visual field. When reading, according to the size of the visual field, reading is divided into three categories: point reading, line reading and surface reading. The point reading field of view is the smallest, only one or two words, and the reading speed is only a few hundred words per minute; the line reading field size is more than a few words, and these words in the field of view are connected in a straight line, and the maximum field of view can reach one line of text. The reading speed can reach more than one or two thousand words per minute; the surface reading field size is more than two lines of text, and the shape of the field of vision is a plane, and the reading speed can reach several thousand words per minute or higher. [0003] One of the most important links in speed rea...

Problems solved by technology

However, when the trainer turns to the actual reading training of paper materials such as books, magazines, newspapers, etc., due to the lack of auxiliary means to demarcate the boundary of the visual field, many difficulties will be encountered. For example, the trainer does not know the size and range of his own visual field. The field of view fluctuates, the field of view tends to shrink and shrink, the boundary between the left and right adjacent fields of view is unclear, and some texts are repeatedly ingested, etc.
