The concept for e-material creating and formatting application prototype

Kristine Mackare, Anita Jansone


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.
