The concept for e-material creating and formatting application prototype

Received Nov 1 st , 2018 Smart technologies and screen use increase, especially for screen-reading and its use in educational reasons. It is helpful and up to date for nowadays people. But perception from the screen is different comparing to perception of printed materials. Technologies development is faster than people adaptation to the new conditions. According to research, it brings up some different problems, especially in vision and ocular health, that affect people life quality and can increase problems in the future. There is a need for the solution. It is believed, well-formatted e-materials could improve users reading comfort and vision health, that can be followed by educational and life quality increase. One of the possible solutions is the e-material formatting application. That can improve the comfort of using e-material in learning and study process and decrease near workload. And the goal could be reached by adapting text formatting for individual needs in addition. Formatting recommendations would be based on user habits research, vision conditions, symptoms and refraction changes research from practice, and on developed recommendations for user-centric and adaptive educational e-material creation and formatting. In this paper, the detailed concept for the application prototype is shown. Keyword:


Introduction
Near work is the work that involves focusing your eyes on a nearby object as the activities done at a short working distance, such as reading, studying (doing homework, writing), computer use, playing video games, or watching TV, etc. all at distance closer than 2m.[1; 2; 3; 4] A big near-work load is a near work for a prolonged period of time.[5] Due to the high visual demands of all near work, especially viewing texts and images, reading, learning both print media and computer screen, are making effects on vision.[2; 6; 7; 8] It has been considered to be a potential cause to myopia development what is one of the biggest nowadays problems.[9; 10] All digital devices are a big part of every person's life in the nowadays technological era.The smart devices use increase as everybody finds them useful on a daily base for solving different problems and spending free time.According to statistical data, at least 51% worldwide population uses the internet and digital devices to provide it.[11] That increase near workload and effect on eyes and vision system.As it is known, reading from printed materials and screen is different.Reading research shown that screen reading is much difficulty [12] and readers need to use different reading model.[13] People vision system is adapting for the new visual information perception model, but the human evaluation process isn't as fast as technology progress.The visual system needs help.There are no possibilities to stop the development of devices, and it would not be useful or wise, but there is a need to try to help achieve a more comfortable and healthier screen reading.There is a need for user-centric and adaptive educational e-materials.Users intuitive ask for the more individual approach for screen work what is related to objective findings.Formatting to e-materials should be applied for natural and comfortable perception and in cooperation with visual processes.In addition, they should be helping the learning process and facilitating memorisation.

The concept of application
The concept for application prototype has been made based on previously developed recommendations for ematerial format-ting what is based on user preference research and oriented on users' individual factors and need.The application idea involves such components as an idea of the tool by itself -what it must do and how to do that, information must contain in the database -, and vision of tool design.It must give a clear understanding of the application to the programmer what must be done.The app must work not only for app creator but also for both e-material creators and e-material users.In addition, the app should provide feedback information for researchers.

The short concept of application
The main idea of the concept is simply represented by a sequence diagram in Fig. 1.It represents three mine edges of the app: user, interface and database.It includes collaboration processes between edges and the mine idea of the apptext formatting of documents based on user groups.

The concept structures
The developed concept consists of: Literature research and analysespublication have been made [15] b.Statistical data analyses both worldwide and localpublication have been made [16; 17] c.Users need research and analysespublication have been made [16; 18; 19] d.Users preferences research and analysespublication have been made [16; 19; 20] e. Patient data research and analysespublication have been made [17] f.Related programs, applications, and tools analysesmaster thesis [14] and some student course work g.Development of recommendations for e-material formattingrecommendations developed, and publication have been made [15 -20] h.The scheme of answers analysesin progress.
For more detailed and more accurate data and recommendations, researches are still in progress and recommendations are updated regularly.
2. The aim of the application is to make e-material textual information formatting in the e-study environment (for the prototype designed for MOODLE type environment with a possibility to adapt) according to the recommendations which are developed to improve the comfort of using e-material in learning and study process and decrease near work load by adapting on individual needs.g.Have the possibility to cancel or make changes in advised formatting parameters h.Additional formatting tools, if the user wants to do it manually or in addition (zoommostly for non-formatted parts of the document as graphs and images, must provide a high quality of magnification; colour masksfor text and background contrast increasing in special conditions; or other needed tools).
5. The application should work fast and qualitatively without program bugs and errors in all stagesin information collecting, analysation process, saving, responding, e-material formatting and document creating.
It must follow all steps correctly and accurately.The application must be easy to use from the regular users' side without additional training.There is a need to be possible to recognise and format popular document formats as word, pdf, excel, etc.The application would be very valuable in case if could be a possibility to format graphs, tables, and images.6.Data base must save all needing information about the userspersonal information, given answers; analysing scheme and adaptation; suggested advice for e-material formatting after analyse and what users prefer (ask the question about a need to use the choice that was used in the previous connection session) or what changes made manually; feedbacks as data about users' comfort responses after use of suggested formatting -survey-generated questions after experience of using new text formatting-short and easy answered, not taking too much users time.7. Interface, design, architecture must contain as much specific information as possible.a.The app interface must look simple but professional at the same time, and easy to percept, it must be designed by related e-material formatting.
b. Must have an individual user profile and login c.User information -survey-generated questionsshort and easy answered, not taking too much users time, provided in two options: The first, regular questioner for all the users, very short for basic information.The second, optional questioner for whom want more individualized advice.
d.During the analysis, there should be a statement that analysis is being made (can be some moving image with text, showing how time analysis will take) e.A suggestion window with a visual example of the proposed formatting format, as text will look like, if new formatting applied, must appear on one side of the page.Next it, on the other side, should be shown non-formatted sample of text from the original document.
f.The user can cancel and not use advised format and use original document format without any changes.
g. Possibility to save advised format with or without manual changes.
h. Button for additional formatting.
i.At the end of the work -assessment of subjective feelings (to be written and executed shortly).
For easier perception of idea and construction of application should add schematic drawings and visual images in the concept.

Purpose:
To be able to use a formatting app, the user at the first needs to create a personal profile, including some personal information (what make a difference for formatting advice) 4.

Conditions:
User must have internet access, email address and/or account in MOODLE 5.
Short description: When you enter web page http: // ... press the "Register" button and enter the data: a name, surname, e-mail address, create a password.Specify specific data about yourself: gender, age, need or not glasses for computer work, etc. Possibility to adapt recommendations for e-material formatting advice after app user testing and feedback and information research -application "learning" process.

Conclusion
The concept includes all application sidesideas, information, involved persons as developers and users, technical solutions and visual design.For easily understandable idea and final application prototype, the concept must be as much detailed and specific as possible.The full concept gives all necessary information for developers and an insight into the final product -application.It describes how application would work stepby-step to reach the main goale-material formatting.The concept is an important part of application designing and programming.As a reasonable next step, research on the possible technical solution for making application prototype has been done in addition by technical side based on developed application concept.A future step is to develop an application prototype by starting coding.The prototype of the application is in need to create to test and analyses users and user needs, offer the best possible e-material formatting and brings it to life.It is the next part of the research.
