Description

Technical part

The present utility model relates to a multisensory aid for literacy, and more particularly to a writing tablet having haptic properties for literacy.

background

Learning disability does not necessarily refer to personal intelligence, but shows that there is a problem in acquiring knowledge. Learning disabled does not mean that these people can not read or do not have sufficient intelligence. The main reason for this is mostly that the brain area is not active enough for speech. The general literacy process of seeing, hearing and writing can not generate sufficient brain stimulation, which makes it difficult for the brain to remember a few words.

"Tactile writing" is one of the "multi-sensory teaching methods" that is particularly important for students with learning disabilities. "Multi-sensory teaching method" refers to the support of learning disabled and young children who want to learn 66 world languages through more than one sense, such as seeing, hearing and touching. Therefore, for children with learning disabilities and toddlers, the best way to teach them is to use more of their feelings, especially touch, which effectively stimulates the touch-and-getch of learning-disabled and toddlers to help memorizing the words.

In the prior art, the alphabetization cards that use the principle of tactile writing require one literacy card per word. For example, if you want to learn four thousand Chinese words, you will need four thousand literacy cards. This expensive literacy fee is hard to afford for most learning disabled people, so they can not take advantage of tactile writing. Once the alphabetization cards have been completed, the text on them can not be changed, so that one set of literacy cards can teach only one type of text, and if you want to learn more than one language, you will need more sets of literacy cards Creating a large number of word cards are very high as well as the procedure is not environmentally friendly. It is extremely impractical to find the required word cards from the many alphabetization cards in use.

On the other hand, about 50% of the world's visual stress patients are learning disabled people who, due to the visual system, are sensitive to particular light colors, especially white light. The symptoms of visual stress can appear as one or more of the following symptoms when reading: words and sentences blur or move, sometimes referred to as rivers or worms (see ). Or the words seem to hold together and float like dancing (see ). Most of the books read always have a white background and white is the reflection of all the colors, causing patients to experience discomfort or fatigue when reading under strong light or even normal light, which seriously affects the reading process.

Description of the utility model

To solve the technical problem that the prior art alphabetization cards require one literacy card per word and the existing literacy cards can not reduce the visual stress, the utility model provides a transparent or semitransparent writing board with haptic properties for sandy surface literacy, thereby providing only with one copy countless words in different languages can be learned.

A tablet having haptic properties for literacy, sequentially provided from bottom to top with a color filter, a substrate and a granule layer, the granule layer being formed by adhering the granules and transparent adhesive to the top of the substrate, and wherein the substrate and the granules are transparent or semitransparent.

Furthermore, the writing tablet with haptic properties is placed on an electronic device, wherein the writing tablet with haptic properties has a thickness of 1.0 mm to 2.3 mm.

Furthermore, the writing tablet with haptic properties has a thickness of 1.8 mm.

Preferably, the substrate is made of polyvinyl chloride or transparent polyethylene or transparent silica gel.

Furthermore, the substrate is made of soft polyvinyl chloride.

Preferably, the substrate is made of hard polyvinyl chloride.

Preferably, a plurality of tapes for screens, which can be stuck on different screens, glued to the underside of the substrate.
Furthermore, the granule layer is a transparent sand layer or a transparent silica gel layer.

Furthermore, the granule layer has a grain size of # 30 to # 400.

Preferably, the granule layer has a # 150 grain size.

The advantage here is that when the transparent or semitransparent writing board with haptic properties is placed on the text, the text on the granule layer is illuminated. By stimulating the user's sense of touch in the process in which the user uses the fingers to write on the granule layer, the cognitive feeling and memory of the user for the text is enhanced, thereby reducing the difficulties of learning-disabled and infants with literacy , On the other hand, the color filter may reduce certain colors of light that will enter the eyes, thereby reducing excessive visual stimulation to the user. This invention is convenient and simple, inexpensive and easy to distribute. Only with a writing tablet with haptic features for literacy and an electronic device, the text is already captured, then learning disabled children and toddlers can learn innumerable words in different languages in the world comfortably both inside and outside.

Detailed description of embodiments

In the following, the embodiments are described in detail with reference to the existing drawings.

The utility model addresses the technical problem that the prior art literacy cards require one literacy card per word and the existing literacy cards can not reduce the visual stress. The utility model provides a colored or colorless writing surface with haptic properties for sandy surface literacy, successively from bottom to top with a color filter (not shown), a substrate 110 and a granular layer 120 is provided, wherein the granular layer is applied to the transparent or semitransparent substrate. When the user places the haptic literacy writing board on the text and then rewrites it with the fingers of the text appearing on the granule layer, the unevenness of the granule layer will stimulate the user's sense of touch, allowing the user to do so based on the original literacy process supplemental brain stimulation, which reduces the difficulty of reading. By setting the color filter so that the haptic writing literacy tablet can appear in different colors or colorless at the user's decision, the light waves of certain colors that can enter the user's eyes are reduced, thereby reducing the user's visual stress reduced and the learning efficiency can be improved. By changing the text in the electronic devices on which the writing board with haptic properties is located, even countless words from all over the world can be learned.

To clarify the present utility model, the following description will be given with reference to the accompanying drawings.

As in 1 and 2 A first embodiment of the present utility model is disclosed, wherein the writing tablet has haptic properties 100 of the utility model on the printed matter 300 is arranged and this is rewritten. In the present embodiment, the printed matter 300 be any paper with text, such as text printed on paper, handwritten text on paper, various typefaces, and so on.

As in 1 shown includes the writing tablet with haptic properties 100 In the present embodiment, a color filter, a substrate 110 and a granule layer 120 on the upper layer of the substrate 110 , After the substrate 110 on the printed matter 300 has been laid, this will then be with your fingers 200 on the granule layer 120 nachgeschrieben.

For rewriting the substrate should 110 and the granule layer 120 transparent or semitransparent, so that the user can see the text on the printed matter 300 see clearly in normal lighting.

In addition, the overall thickness of the substrate affects 110 and the granule layer 120 also the usage experience of the rewrite. An overly thick writing board with haptic properties 100 tends to float due to refraction, which does not favor rewriting. In addition, an excessively large thickness probably also affects the light transmission. The optimum thickness range is tested by giving the user different thicknesses of the writing tablet with haptic properties 100 are given. Through experiments, it was assumed that the total thickness of the substrate 110 and the granule layer 120 the thickest is 2.3 mm, the thinnest is 0.3 mm and the optimum thickness is 0.6 mm.

Since the subject of the rewrite the printed matter 300 In general, for a better bonding effect, a flexible film will be used as the substrate 110 sandblasting on the flexible film or sand grain sticker applied directly to the flexible film to form a granular layer 120 to build.

In this embodiment, the user places the writing tablet with tactile properties 100 on the printed matter 300 off to make sure one side of the substrate 110 at the printed matter 300 is attached, and then the finger 200 used the on the granule layer 120 to rewrite the displayed text. Compared to the conventional spelling with a pen, this embodiment allows the user to increase the stimulation of the touch feeling during the writing operation, thereby reducing the difficulty of literacy.

The present utility model also provides a second embodiment, as in 3 to 5 shown, with the writing tablet with haptic properties 100 for rewriting on the electronic device 400 is arranged. The electronic device 400 may be a display screen of a mobile phone, a tablet computer, a computer, etc. In this embodiment, the haptic writing tablet can be used in combination with computer software or computer games that are actually used for literacy, thereby increasing the interest in literacy, activating the user's enthusiasm, and also improving learning efficiency.

As in this embodiment, the subject of the rewriting to the electronic device 400 has changed, provides the substrate made by the flexible film 110 not an optimal embodiment. To ensure stability during rewriting, the material of the substrate becomes 110 generally changed into a hard or soft transparent or semitransparent plate material. For example, there is a substrate 110 Made of a material such as polyvinyl chloride (PVC), transparent polyethylene (PE) or transparent silica gel, so that when rewriting it is avoided that the pressure of the finger deformation of the substrate 110 generated and caused a wrong touch. Therefore, the granule layer 120 by adhering transparent sand particles or transparent silica gel particles with a transparent adhesive on the surface of the substrate 110 be formed.

Depending on the addition of the plasticizer, PVC can be divided into two categories: hard and soft. In this embodiment, when the substrate 110 Made of hard PVC, several tapes for screens need 130 at the bottom of the substrate 110 be glued. If a tablet computer, for example, as an electronic device 400 Used are a variety of adhesive tapes for screens 130 at the bottom of the substrate 110 to the frame of the electronic device 400 glued so that the sliding of the finger 200 When writing the writing board with haptic properties 100 not moved to deviate from the position. To prevent the tapes for screens 130 During use, hide the display area of the screen, the tapes for screens 130 generally at the edge of the back or at a corner position of the substrate 110 arranged.

If the substrate 110 Made of soft PVC, the variety of adhesive tapes needs for screens 130 not on the bottom of the substrate 110 be glued, and the substrate 110 sticks directly to the electronic device 400 without the glide of the finger 200 when rewriting the positional deviation of the board with haptic properties 100 caused.

The difference from the previous embodiment is that the subject of the rewriting in the present embodiment is the electronic device 400 is. If the electronic device 400 has a touch function, it is then easy to cause an incorrect trigger in the rewriting process, which affects the rewriting learning experience. Therefore, it is necessary to readjust the thickness to obtain a sufficiently high stability while ensuring sufficient clarity.

The following experiment was conducted by participants aged 6 to 14, who used this haptic writing tablet to rewrite the Chinese text on the tablet computer. The test chart with haptic properties all have roughness of # 150. The experimental results are shown in Table 1. Table 1 Clarity of the text Stability of the text on the touch screen 1. unacceptably unclear 2. acceptable unclear 1. unacceptably unstable 3. clearly 2. acceptable unstable 3. stable 0,6mm 0,8mm 1,0mm 1,3mm 1,8mm 2,3mm 0,6mm 0,8mm 1,0mm 1,3mm 1,8mm 2,3mm 3 3 3 3 3 3 1 1 1 1 3 3 3 3 3 3 3 3 1 1 1 3 3 3 3 3 3 3 3 3 2 2 1 3 3 3 3 3 3 3 3 2 1 2 1 2 3 3 3 3 3 3 3 3 1 1 2 2 3 3 3 3 3 3 3 3 1 1 1 3 3 3 3 3 3 3 3 3 1 1 2 3 3 3 3 3 3 3 3 3 1 1 1 3 3 3 3 3 3 3 3 3 1 1 2 3 3 3 3 3 3 3 3 3 1 1 1 2 3 3 3 3 3 3 3 3 1 1 1 3 3 3 3 3 3 2 2 2 1 1 2 2 3 3 3 3 3 3 3 3 1 1 2 3 3 3 3 3 3 3 3 2 1 1 3 2 3 3 3 3 3 3 3 3 2 3 3 3 3 3 3 3 3 3 3 3 1 1 1 2 3 3 3 3 3 3 3 3 1 2 1 3 3 3 3 3 3 3 3 3 2 3 2 3 2 3 3 3 3 3 3 3 1 1 3 3 3 3 3 3 3 3 3 3 2 2 1 3 3 3 3 3 3 3 3 3 1 1 1 3 3 3 3 3 3 3 3 2 1 1 3 3 3 3 3 3 3 3 3 3 1 1 2 3 3 3 3 3 3 3 3 3 1 1 2 1 2 3 Average number 3 3 3 2.96 2.96 2.83 1.17 1.33 1.67 2.58 2.92 3.00

The above experiment found that when the electronic device 400 as the object of the rewriting is used, the total thickness of the writing tablet with haptic properties 100 1.0 mm to 2.3 mm, and that the optimum thickness is 1.8 mm.

The difference between reading and writing disabled people to ordinary people is that these disabled people are sensitive to too intense or too little intense touch. In the above two embodiments, the granule layer becomes 120 used to create the touch and the roughness of the granule layer 120 also affects the user experience. An excessively smooth granule layer 120 can not produce sufficient touch to produce sufficient brain stimulation when rewriting. An excessively rough layer of granules 120 can cause pain while writing and even injure the skin.

An experiment was conducted on this problem, with participants aged 6 to 14 writing the Chinese text to determine the roughness. The experimental results are shown in Table 2. Table 2 Comparison of the roughness of the sand surface Comparison of the pain 1. unacceptably painful 1. highest roughness 2. acceptable painful 2. medium roughness 3. not painful 3. lowest roughness # 30 # 60 # 150 # 320 # 400 # 30 # 60 # 150 # 320 # 400 1 1 2 3 3 1 1 2 3 3 1 1 2 3 3 1 1 2 3 3 1 1 2 3 3 1 1 3 2 3 1 1 2 3 3 1 2 2 2 2 1 2 2 3 3 1 1 3 3 3 1 1 2 3 3 1 1 2 3 3 1 1 2 2 2 1 2 2 3 3 1 1 2 2 2 2 3 3 3 3 1 1 2 3 3 1 3 2 3 3 1 1 2 2 3 2 3 3 3 3 1 1 2 3 3 1 1 2 3 3 1 1 2 2 3 1 2 2 2 3 1 1 2 3 3 1 1 2 3 3 1 1 2 3 3 1 1 3 3 3 1 1 2 3 3 1 1 2 3 3 1 1 2 3 3 2 2 2 3 3 1 1 2 3 3 1 1 3 3 3 1 1 2 3 3 1 1 2 3 3 1 1 2 2 2 1 3 3 3 3 1 1 2 2 3 2 2 2 3 3 1 1 2 2 3 1 1 2 3 3 1 1 2 3 3 1 1 2 2 3 1 1 2 3 3 1 2 3 3 3 1 1 2 3 3 2 2 2 3 3 Average number 1.00 1.04 2.08 2.71 2.88 1.21 1.63 2.33 2.83 2.96

From this experiment, it is known that the acceptable roughness range is # 30 to # 400, and the larger the number, the smoother. The optimal roughness is # 150.

Most of the books read always have white backgrounds and white is the reflection of all the colors, causing patients to experience discomfort or fatigue when reading under strong light or even normal light, seriously affecting the reading process. Reducing the light waves of certain colors that can enter the user's eyes reduces the visual stress and helps the learning disabled to read. In order to further investigate the influence of the "text background color" on reading, the utility model therefore wants to find out different colors that can make it easier for the learning disabled to determine the required colors for the respective transparent or semitransparent substrate for different learning disabilities.

To understand the impact of "text background color" on reading, students were tested with learning disabilities in primary and secondary schools to see if the color of the text background of the written section can reduce visual stress and facilitate reading. The conclusion is shown in Table 3. Table 3 Optimal color (number of students) White (white) 8th Gray blue (blue gray) 7 Sea Blue (Aqua) 11 Turquoise (Turquoise) 11 Green 3 Yellow 3 Dark yellow (goldenrod) 2 Purple (purple) 4 Pink (peach) 1 Rosy (rose) 2 Gray (gray) 1 Sum (number of students) 53

The experiment found that 85% of the learning disabled believe that the colorful background of the text can facilitate reading. Only 15% of the learning disabled believe the white background is the best. Sea blue and turquoise are among the two colors that make the most of the learning disabled. Therefore, the utility model can offer consumers a variety of colors to choose from, which is very helpful for the learning disabled.

The various colors required for the transparent or semitransparent substrate may be added to the raw material of the substrate by adding a dye of a corresponding color 110 or by one under the substrate 110 arranged color filter can be realized so that the product described in this utility model is colored or colorless to meet the different needs of different users.

In the above embodiments of the present utility model, a granule layer is added to the transparent or semitransparent substrate. After the user has placed it on the text, you can then rewrite with your fingers on the granule layer. The user will receive stimulation of the touch during the writing process, thereby enhancing the cognitive perception of the text, thereby reducing the difficulty of the learning disabled and infants in the literacy process. On the other hand, a color filter is placed under the substrate to make the tablet with haptic properties appear in different colors and to reduce the light of certain colors that will enter the eyes, thereby reducing the user's visual stress.
