Description

The inventive utility model relates to the field of computer technology, educational devices and electronic devices for individual use, allowing you to read visual information, namely, electronic devices for individual use for use in educational processes, when working on the Internet, comfortable video and photo viewing, as organizer, for presenting various kinds of presentations or demonstrations, for editing various documents, as a gaming device, etc.

A personal electronic device (PES) is a device, one of the areas of application, which can be the educational process and which allows replacing a traditional paper textbook. Almost all teachers note the ease of use of a personal electronic device by students, the increase in students' motivation and interest in working with a subject using a technical device, and the pleasure of using PES in class and at home.

The concept of the device in the educational process is to make it not just a substitute for paper textbooks, but a learning tool with advanced features compared to traditional textbooks. The main advantage of the electronic manual is interactivity. PES technologies, on which electronic manuals will work, will allow, in addition to text, to provide students with the opportunity to open audio files, videos, copies of various documents, cross-references from other manuals and encyclopedias. It is assumed that for the duration of the lesson personal electronic devices of students can be defined in a single network. The teacher will be able to work with each device from his tablet or other gadget, comment on the work of students, organize groups, give and check assignments. The work results are automatically recorded in an electronic journal and diary, statistics and analytics are available directly during the lesson and are stored in a database with guaranteed storage, eliminating the need for paper documentation. In addition to new opportunities in the educational process, PES also have other advantages over paper ones, in particular, the absence of printing costs, lightening of the weight of educational materials that the student is forced to carry with him, and the preservation of the forest that is being cut down for paper production.

Various countries are actively involved in the implementation of personal electronic devices in the educational process. In South Korea, since 2012, teachers have been trained in working with electronic manuals. In the United States, a whole program is underway to develop them. Australia's e-textbook learning system is also in the pipeline. In Norway, there is a model for providing a personal electronic device to each student, which, as a result, has increased the level of overall performance. In 2011, the Russian Ministry of Education and Science conducted an experimental introduction of electronic textbooks in 38 schools in 9 regions of Russia. As part of the experiment, devices from different manufacturers were tested. As a result of the experiment, some media outlets wrote about the readiness of the relevant institute of the ministry to continue implementation. In the spring of 2013, an experiment on the introduction of electronic textbooks was conducted in 75 Moscow schools. Its duration was 60 days, teachers rated its results positively, but noted that electronic training materials need to be finalized.

On September 1, 2014, the Moscow City Department of Education, together with the Enlightenment publishing house, began conducting an experiment in the framework of the Electronic Educational Environment project on the introduction of electronic textbooks in six schools. Classes were held in four disciplines: in history, chemistry, biology and geography.

According to the order of the Ministry of Education and Science of the Russian Federation No. 1559 dated December 8, 2014 from January 1, 2015 all Russian schools are obliged to switch to those textbooks for which an electronic version will be released.

In the academic year 2017-2018, the National Center for Electronic Education as a customer tested the Russian hardware and software complex for electronic education, which includes a single platform model for hosting all educational content; a dual-screen panel personal access device specially designed for the educational process; interactive content of electronic textbooks developed on the basis of and in accordance with textbooks on a printed basis included in the Federal List of Textbooks. About 9,000 students from 85 schools in Yekaterinburg and the Sverdlovsk Region participated in the testing of the complex. The analysis of the results indicates a positive reaction of students to the use of the electronic educational complex in the learning process. The presence of positive dynamics indicates a positive response from the control classes to the use of the electronic educational complex in the learning process.

Instead of a set of textbooks and additional training materials (workbooks, outline maps, etc.), the student’s portfolio will have one tablet, its weight does not exceed one kilogram.

When the class is working with personal electronic devices, the teacher has a real opportunity to give each student a separate task, based on his level of knowledge or topics learned and missed. For normal learning, students need tablets or laptops. And quite powerful and with good screens. As shown by previous studies, electronic ink screens do not adversely affect vision.

Various constructions of electronic interactive books are widely known from the prior art, with the help of which it is possible to carry out various processes, in addition to its main function - books. In particular, the ability to exchange information with other users, receive information from the Internet, use various applications, etc. In particular, from the patent RU 2136053 C1, 08.27.1999, G09B 5/00, an electronic book is known having a storage medium, a device for inputting a storage medium and consisting of two hingedly connected flat covers such as a diplomat bag, while the screen of the video monitor is located on the inside of the two covers. The disadvantage of an electronic book is that it can only display information contained on the media, because controls are not provided in it.

Also known is the electronic book according to the patent RU 118085 U1 dated 01/19/2012, containing a housing with two articulated parts, on the inside of one of which is located the first display (A), made by electronic paper technology, for placing information in it, and on the inside of the other there is a second display (B) made using a resistive TFT-display technology that reproduces multimedia information, the first part of the housing, on the inside of which is the first display (A), also contains an electric source power supply and at least one receiving module for telephone radio networks, while the second part of the housing, on the inside of which a second display (B) is located, contains at least one interface for exchanging data with at least one peripheral device .

The closest technical solution to the claimed is an interactive electronic book patent RU 125364 U1 from 03/30/2012. The specified document is adopted as a prototype. This patent discloses an electronic book containing a graphic display for displaying text and contextual reference data explaining the specified text, and a connection component associated with the data storage unit for outputting contextual reference data at the user's command, as well as navigation buttons and menus located at the bottom of the display, a power source, a processor and a graphics processor, characterized in that the connection component is made in the form of at least one communication button, located vertically along the display to select contextual reference data from a set of reference data related to a given part of the text, the data storage unit including a text storage component for storing texts, a context storage component for storing contextual links, an indexing component for reproducing a text table of contents and contextual links, a component for generating tests for reproducing quizzes based on text and contextual links, a marking component for issuing Lenia part of the text that corresponds to the content link, and update component for updating the text and contextual links.

These devices have a swivel connection of displays, which by its design has a cumbersome and inconvenient use of these technical means by the user, and also increases the weight of the device and reduces the efficiency of the battery.

The objective of the claimed utility model is to expand the arsenal of funds for a specific purpose. Those. creation of a two-screen personal electronic shockproof device designed for user training and development, providing a careful attitude to vision, and having the function of switching between screens that are adapted to interact with both the stylus and the user's fingers.

The technical result of the claimed utility model is the implementation of the utility model of the specified purpose.

Also, when using the device, the following positive effects are manifested: an increase in the efficiency of training and user development, as well as ease of use by increasing information content and ergonomics. However, weight loss, respect for vision and increased efficiency of energy consumption by the device occurs due to a change in the form of the claimed technical solution and the introduction of new structural elements.

In addition, the results of the above approbation revealed the following points laid down in the development of this PES:

- in the total time of using PES in the educational process, the situation when the student needs simultaneous work with content on two screens (watching video and completing the task on the second screen) takes no more than 2-3 minutes, which means that it is negligible. At the current level of technical literacy of students it is not difficult for them to familiarize themselves with the video material, return to the assignment on the second screen.

at home, the user often prefers the usual work with a color screen. Under all conditions, the user prefers more compact and lightweight devices.

The technical result is achieved due to the fact that the proposed device is a two-screen personal electronic shockproof device designed for user training and development, providing a careful attitude to vision, and having the function of switching between screens that are adapted to interact with both the stylus and fingers user, including a monoblock case, a common single electronic part, a single common power supply system, mechanical and sensor controls phenomena and a set of external connectors, while one screen is a color fast-response based on IPS technologies, for displaying multimedia content, the second screen is made using E-ink technologies and works in reflected light, while the screens are located on different (front) sides of the device, switching between the screens is carried out by pressing a button, or automatically, and in one of the corners of the case there is a stylus slot with a stylus located in it, also the device screens are equipped with capacitive touch panels fins to control the user's fingers, while both screens of the device are equipped with EMR touch panels allowing the use of a stylus, during use of which the screens of the device become insensitive to the touch of fingers or the user's hand, while the corners of the device are protected by rubber pads.

The finger of a person for delicate work with the tablet is not very convenient, for example, for writing letters, drawing, plotting, working with volumetric drawings. Therefore, in the learning process, a stylus is especially needed.

Personal electronic device contains:

- Monoblock housing with two screens on both planes.

- A common single electronic part, consisting of a processor, a graphic coprocessor, operational and long-term memory, screen controllers and external interfaces, rear and front cameras, a microphone and speakers, wireless communication modules.

- A single common power supply system, consisting of a battery of sufficient capacity, ensuring active use of the device during the day, a connector for the charger and a charge controller, guaranteeing a full charge at night. The intended target audience (children and adolescents) imposes increased requirements on the electrical and fire safety of the power supply system, which is achieved by a special design and relatively low battery packing density to avoid damage due to mechanical deformation. The low packing density of the battery reduces the risk of internal short circuits and fire due to mechanical microstrains that occur during operation. Known cases of scandals associated with the ignition of leading branded devices are due to the presence of excessively tight battery packaging, in pursuit of maximum capacity and runtime. Since the device is intended for use by children, maximum attention is paid to safety.

- Mechanical and touch controls, located taking into account the requirements of ergonomics and ease of use.

- A stylus that works on both screens, which allows not to keep the brush on weight during use, but to naturally rest it on the work surface, and a reliable socket for it in the case.

- A necessary set of external connectors - charging, data transfer, headphone and peripherals.

A distinctive feature of the IPS screen is the special arrangement of crystals - they are evenly spaced along the entire plane of the screen, parallel to each other. Thanks to this, you can forget about the two main problems of the LCD - poor color reproduction and a small viewing angle. The excellent color rendering of the IPS matrix is especially pronounced when viewing photos and working with graphic images - if the original image contains black color, it will remain that way on the screen, will not “go” to gray and will not become too contrasty. Even in sunny weather, nothing will prevent you from viewing the pictures on the IPS monitor - everything will be clearly visible and the tablet owner will not have to cover the screen with his hand to consider something. A matte protective film will protect from sun glare.

Among the advantages of OLED technology over traditional LCD screens: almost perfect black color due to the fact that each subpixel is an independent light source - there is no spurious glow of the entire screen in the dark, black pixels are simply turned off; saturated colors; wide color gamut - 90% of the color space. Accordingly, the light exposure of these screens is much lower than that of its predecessors, and the light is much softer and harmless to the eyes.

E-ink technology is an information display technology designed to simulate conventional printing on paper and based on the phenomenon of electrophoresis. Electronic paper forms an image in reflected light like ordinary paper and can store an image of text and graphics for a sufficiently long time, without consuming electrical energy and spending it only on changing the image. The technology allows you to arbitrarily change the recorded image.

Mirasol displays are close in energy efficiency to electronic ink screens. Mirasol screens are based on the formation of a color image due to the principle of interference of light waves, which is often found in nature, butterfly wings are an example. A huge plus of such a screen is that additional illumination is not required for reading from it under normal lighting. The level of harmfulness to vision in such screens is minimal.

In FIG. 1, 2 shows a general view of the device. In FIG. 3 shows a diagram of a tablet computer on the Eink side of the screen and the side of the device. FIG. 4 is a schematic drawing of the claimed technical solution from the side of the IPS screen, side, upper and lower sides of the device.

The inventive device in the current audit preferably has the following specifications:

- chipset - central processing unit (CPU) - RK3368 from RockChip (8-cores, Cortex-A53 up to 1.5 GHz);

- screen - display (10.1 '' IPS (primary) - 1280 × 800 pixels; 9.7 "Eink (front, on the back) - 16 shades of gray), capacitive touch panel + EMR (stylus), glass with scratch protection, oleophobic coating;

The developed methods can be implemented with other computer system configurations, including a processor, a graphics processor, a chipset, operational and long-term memory, a motherboard, external interface controllers, type and resolution of screens, a set of controls and external connectors. Also, dimensions, proportions, shape, materials and design of the case, location and set of control elements can be changed while maintaining the general concept and purpose of the device.

Aspects of this proposal can also be implemented in a distributed computing environment where specific tasks are performed by remote processing devices that are connected through a communications system. In a distributed computing environment, program modules can be located in both local and remote memory storage devices.

Computer-readable storage media can be any available storage media that can be accessed by a computer, and include both volatile and non-volatile media, removable and non-removable media. As an example, computer-readable storage media may be implemented by any method or information storage technology, such as computer-readable instructions, program modules, structured data, or unstructured data. Computer-readable storage media may include, but are not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, DVD disc or other optical disk storage, magnetic tapes, magnetic tape, magnetic disk storage, or other magnetic devices data storage, or other tangible and / or intangible media that can be used to store the desired information. Computer-readable storage media may be accessed by one or more nearby or remote computing devices.

A user can operate the PES through one or more wired / wireless input devices, such as a keyboard and pointing device, such as a mouse. Other input devices (not shown) may include a microphone, IR remote control, joystick, gamepad, stylus pen, touch screen, etc. These and other input devices often communicate with the processing unit through the interface of the input device, which is connected to the system bus, but can be connected by other interfaces, such as a parallel port, IEEE 2394 serial port, game port, USB port, IR interface, etc. d.

The above description of the illustrated embodiments of this development is not intended to be exhaustive or to limit the disclosed embodiments to the exact disclosed forms. While certain embodiments and examples are described herein for illustrative purposes, various modifications are possible, which are considered within the scope of such embodiments and examples, which are obvious to a person skilled in the art.

In this regard, while this development has been described in connection with various embodiments, and accordingly illustrated, it should be understood that other similar embodiments may be used or modifications, and additions may be made to the described embodiments in order to accomplish the same. similar, alternative, or equivalently replacing. Therefore, the disclosed object should not be limited to the single embodiment described herein, but rather should be considered in breadth and scope in accordance with the appended claims.

Improving the effectiveness of training, user development (in relation to students), ease of use of the device is carried out by increasing the information content and ergonomics of the claimed technical solution. It is not necessary to carry out uncomfortable manipulations with the articulated types of tablets, it is enough to turn the tablet over with a different screen and begin to perform work of a different kind. Reducing weight, respect for vision and increasing the energy efficiency of the device’s energy consumption occurs due to a change in the form of the claimed technical solution (refusal of articulation of two screens, which implies an increase in the weight of the housing structure due to the weight of the mount itself), the introduction of new structural elements (technology screens IPS, OLED and similar; screens operating in reflected light E-ink, Mirasol and similar) and special design and packing density of the battery to avoid damage after Wie mechanical deformations. Screens designed using these technologies are the least harmful to the user's eyesight. At the same time, the installation of an IPS, OLED screen, or similar, in the tablet’s design does not mutually exclude each other, but is an alternative option (a special case, or an addition) to the type of working device when a single technical result is achieved. The same can be said for E-ink, Mirasol and similar screens - these are special cases of the implementation of the corresponding features (screens operating in reflected light) of an independent item.

Thus, all the structural elements of the claimed device are a single inventive concept and together achieve the goal.

The technical capabilities of PES allow you to embed in the text of the textbook not only static images, as in traditional prints, but also use sound, video clips, animated inserts, and three-dimensional dynamic models.

Computer technology allows the student to interest the subject studied. For today's young people, the computer and everything connected with it is increasingly becoming a natural life background. Gradually, a new aesthetic begins to take shape, originating in the design of computer programs; working with a computer (and even more so, playing on it) is no longer something out of the ordinary, but rather the opposite. Therefore, it is quite natural that a teacher who uses a computer in the learning process (and the more the better) is perceived by students as a closer, more modern person. Which, in turn, also affects the speed of establishing interpersonal relationships, and therefore - the effectiveness of training.

PES allow the teacher, once competently creating their content, to constantly update and replenish it without additional time and material costs.

In addition, the author may in his publication provide links to additional information located on the Internet. Moreover, given the popularity of the Internet among today's youth, these links can really be used.
