Description

Tactile tablet

Technical field

The utility model relates to an auxiliary tool for multi-sensory words, and more particularly to a tactile tablet.

Background technique

Learning disabilities are not necessarily related to personal intelligence. It is a reflection of the way to wisdom. Learning disabilities do not mean that these people can't read or have IQ deficiency. Most of the reason is because the brain language area is not active enough. The general eye, ear, and handwriting literacy process can't produce enough brain stimulation, which makes the brain difficult. Memory part of the text.

“Tactile Handwriting” is one of the “multi-sensory teaching methods”, which is a particularly important learning method for students with learning disabilities. “Multi-sensory teaching method” refers to helping the learning disabilities and children learn the 66 languages of the world through more than one senses such as sight, hearing and touch. Therefore, for learners and young children, the best teaching method is to use more of their feelings, especially the use of touch, which will effectively stimulate the learning and development of children's brain tactile nerves to help memorize the words.

In the prior art, a literacy card using the tactile handwriting principle requires a literacy card per word. In Chinese, for example, if four thousand words are to be learned, four thousand literacy cards are required, and the cost of literacy is high, so that most people with learning disabilities cannot Burden, so you can not enjoy the benefits of touch-sensitive handwriting; in addition, once the literacy card is completed, the above text can not be changed, so a set of literacy cards can only learn one type of text, want to learn a variety of words, Multiple sets of literacy cards are required; the cost of producing a large number of word cards is high and not environmentally friendly; it is extremely inconvenient to find the required card when using a large number of literacy cards.

On the other hand, people with visual impairment of about 50% of the world are learning disabilities, and those with learning disabilities are sensitive to certain colors of light, especially white light. Symptoms of visual stress may appear as one or more of the following when reading: word sentences become blurred or moving, sometimes described as rivers or worms (see Figure 7); or words appear to stick together, constantly floating, It's like dancing (Figure 8). Since most of the books read are white, white is the reflection of all colors, which causes the patient to experience discomfort or fatigue in strong light or even normal light, which seriously affects the reading progress.

detailed description

The present invention will be described in detail below with reference to the accompanying drawings.

The utility model is directed to a literacy card currently used by a learning disabled person and a child, and requires a literacy card for each word and an existing literacy card which cannot alleviate the technical problem of visual pressure, and provides a filter color film arranged in order from bottom to top. A colored or colorless tactile tablet of the layered structure of the substrate 110 and the particle layer 120, by adding a layer of particles on a transparent or translucent substrate, the user will record a touch of the present invention. After the word board is covered on different characters, the text displayed on the particle layer with the finger is copied, and the roughness of the particle layer can stimulate the user's touch, so that the user adds one more stimulation to the brain based on the original literacy. , thereby reducing the difficulty of literacy; by setting the filter color to make the tactile tablet appear different colors or colorless, allowing the user to select, thereby reducing the light waves of certain colors into the eyes, and alleviating the visual pressure of the user, improving Learning efficiency. Through the tactile tablet to cover the text changes in electronic devices (such as tablets), you can even learn countless words from all over the world.

In order to explain the present invention more clearly, the following description will be made with reference to the accompanying drawings.

As shown in FIG. 1 and FIG. 2, a first embodiment of the present invention is disclosed in which the touch sensitive tablet 100 of the present invention is overlaid on the printed matter 300 for copying. In the present embodiment, the print 300 may be any paper with text, such as text printed on paper, handwritten text on paper, various types of copybooks, and the like.

As shown in FIG. 1 , the tactile signature board 100 of the present embodiment includes a filter color layer, a substrate 110 and a particle layer 120 on the top layer of the substrate 110. After the substrate 110 is overlaid on the print 300, the finger 200 is used on the particle layer 120. Linyi.

Since the substrate 110 and the particle layer 120 are to be transparent or translucent, the user can clearly see the text on the printed matter 300 under normal illumination.

In addition, the total thickness of the substrate 110 and the granular layer 120 also affects the experience of Linyi: an excessively thick tactile tablet 100 is prone to floating characters due to light refraction, which is not conducive to copying; in addition, excessive thickness is also likely to affect Light transmission. The optimum thickness range is tested by giving the user a different thickness of the tactile tablet 100. Through experiments, the total thickness of the substrate 110 and the particle layer 120 may be 2.3 mm at the longest, 0.3 mm at the thinnest, and 0.6 mm at an optimum thickness.

In this embodiment, the object of Linyi is the printed matter 300. In order to obtain a better bonding effect, a flexible film is generally selected as the substrate 110, and then sandblasting is performed on the flexible film, or directly in the flexible state. A sand sticker is applied to the film to form a particle layer 120.

When the embodiment is used, the user covers the touch sensitive tablet 100 on the printed matter 300, and ensures that one side of the substrate 110 is attached to the printed matter 300, and then the finger 200 is used to write on the text displayed on the granular layer 120. In the conventional way of writing with a pen, this embodiment enables the user to increase the tactile stimuli during the writing process, thereby reducing the difficulty of literacy.

The present invention also provides a second embodiment as shown in FIGS. 3 to 5, in which the tactile tablet 100 is placed on the electronic device 400 for copying. The electronic device 400 can be a display screen of a mobile phone, a tablet computer, or a computer. In this embodiment, the tactile tablet can be used in combination with computer software for learning text or computer games to increase literacy and motivate the user. Improve learning efficiency.

In this embodiment, since the temporary object has been changed to the electronic device 400 in this embodiment, the substrate 110 manufactured by the flexible film is not an optimal embodiment. In order to ensure the stability during the temporary operation, the material of the substrate 110 is generally changed. For a hard or soft transparent or translucent sheet, for example, a substrate 110 made of a material such as polyvinyl chloride (PVC), transparent polyethylene (PE) or transparent silica gel, so that the substrate 110 is not used by fingers when it is copied. The pressure creates deformation and causes a false touch. At this time, the granular layer 120 can be formed by adhering transparent sand particles or transparent silica gel particles with a transparent glue on the surface of the substrate 110.

According to the amount of plasticizer added, PVC can be divided into two categories: hard and soft. In this embodiment, if the substrate 110 is made of rigid PVC, a plurality of screen adhesive stickers 130 need to be attached to the bottom of the substrate 110. A tablet computer is used as the electronic device 400. The plurality of screen adhesive patches 130 at the bottom of the substrate 110 are attracted to the frame of the electronic device 400, so that the sliding of the finger 200 does not drive the touch sensitive tablet 100 to be offset when copying. position. Considering that the screen sticker 130 avoids obscuring the display area of the screen when it is used, the screen sticker 130 is generally disposed at the edge of the back surface of the substrate 110 or at a corner position.

If the substrate 110 is made of soft PVC, it is not necessary to attach a plurality of screen adhesive stickers 130 on the bottom of the substrate 110, and the substrate 110 is adhered to the electronic device 400 by itself, without the sliding of the finger 200 driving the touch sensitive tablet 100. Move position.

The difference from the previous embodiment is that the object of the present embodiment is the electronic device 400. If the electronic device 400 has a touch function, it is easy to cause false triggering in the process of copying, which affects the learning experience of Linyi. Therefore, it is necessary to reset the thickness to obtain a sufficiently high stability while ensuring sufficient definition.

The following experiments were conducted by a 6-14 year old experimenter on a tablet computer with Chinese characters. The experimental samples were all tested with #150 roughness, and the experimental results are shown in Table 1.

Table 1

Through the above experiments, when the electronic device is used as a temporary object, the thickness of the entire tactile tablet is limited to 1.0 mm to 2.3 mm, and the optimum thickness is 1.8 mm.

Many people with dyslexia are different from ordinary people. They are usually allergic to the touch or are too low. In both of the above embodiments, the particle layer 120 is used to generate the touch. And the grain layer 120 is thick The degree of roughness also affects the experience during the actual use: too smooth particle layer 120 can not produce enough touch, can not produce enough brain stimulation when copying; and too rough particle layer 120 will allow users to copy It causes pain and even wears the skin.

In response to this problem, an experiment was conducted with Chinese 6-year-old experimenters to determine the roughness. The experimental results are shown in Table 2.

Table 2

From this experiment, it is known that the acceptable roughness ranges from #30 to #400, and the larger the number, the smoother the smoothness, and the optimum roughness is #150.

Since most of the books read are white, white is the reflection of all colors, which causes the patient to experience discomfort or fatigue when exposed to strong light or even normal light. If you can reduce the light waves of certain colors into the eyes, you can reduce the visual stress and help the disabled to read. Therefore, in order to further understand the influence of the "text background color" on reading, the utility model finds different colors which can make the learning disabled person more comfortable to read, to define a transparent or translucent substrate for different learning disabilities. The color of the whisker.

In order to understand the influence of “text background color” on reading, the students with learning disabilities in primary and secondary schools were tested to find out if the color of the text background of the written paragraph can reduce visual pressure and help to read. The conclusion is shown in Table 3.

table 3

	最佳的颜色(人数)Best color (number of people)
白(White)White	88
灰蓝(Blue Gray)Gray Gray	77
湖蓝(Aqua)Lake Blue (Aqua)	1111

紫(Purple) Purple	44
桃(Peach) Peach	11
玫瑰(Rose) Rose	22
灰(Gray) Gray	11
总计(人数)Total (number of people)	5353

The experiment found that 85% of people with learning disabilities think that if the background of the text has color, it can make reading. More comfortable, and only 15% of people with learning disabilities think that the white background is the best. Among them, lake blue and green are the two colors that make the most difficult to learn for the disabled. Therefore, the utility model can provide a variety of colors for consumers to choose, which is very helpful for those with learning disabilities.

The different colors required for the transparent or translucent substrate can be realized by adding a dye of a corresponding color to the raw material of the production substrate 110, or can be realized by a color filter disposed under the substrate 110, so that the present invention The products are colored or colorless to suit the different needs of different users.

The above embodiment of the present invention increases the particle layer on a transparent or translucent substrate, and the user covers it on the particle layer with a finger after covering it on the text. The user obtains tactile stimulation during the writing process, increasing the user's cognitive sensation of the text, thereby reducing the difficulty of the learning disabled person and the child in the literacy process. On the other hand, by providing a color filter on the lower layer of the substrate, the tactile tablet is rendered in a different color, and the filter color can reduce the light of certain colors from entering the eye, thereby reducing the visual pressure of the user.

The above is only a preferred embodiment of the present invention, and many changes can be made in the specific embodiments and applications according to the idea of the present invention as long as the changes are not deviated from the present invention. The concept is all within the scope of protection of the present invention.
