abstract: In practice, alternative medical treatment by using colors proved to be very effective in solving the problem of dyslexia. According to the International Association of Dyslexia, dyslexia is characterized by difficulties with accurate and/or fluent word recognition and poor spelling and decoding abilities and "developmental dyslexia" is often used as a synonym for reading disability. In previous studies, it has been found that changing the color of the background for reading and writing can accelerate progress towards overcoming the problem of dyslexia. Color has been used in reading tasks with dyslexic subjects in a number of different ways and for different purposes. Colors produce different physiological responses in blood pressure, heart rate, respiration, digestion, body temperature, and brain activity. In the study âGood Background Colors for Readers: A Study of People with and without Dyslexiaâ is shown that warm colors, i.e. peach, orange, and yellow lead to significantly faster readings, while cool colors, blue-grey, blue, and green, lead to significantly longer reading times. There is also a lot of studies which measure the significance of font type, size on reading in children with dyslexia. Our goal is to use sensors for monitoring physiological parameters (electrical activity of the brain, heart rate, elector dermal activity and eye movement) and find the correlation between changes in colors and those parameters in order to better understand the reading process in children with dyslexia and how o improve their abilities to read normally. Dyslexic individuals exhibit a longer duration of fixations, shorter saccades and thus more fixations in reading than normally developing readers of the same chronological age. Such eye movement disorders have been reported in different languages, irrespective of their degree of transparency. In purpose of the the research study is created a sensor hub of 4 synchronized devices: Smarting (small, simple and mobile EEG device, which supports synchronization with other sensors and simultaneous multi-amplifier streaming via lab streaming layer), EDA (electro dermal activity sensor), Heart rate (ECG) and Eye tracking (IMotions sensor). In this article are shown the results of the first phase of the research, in which took part about 50 children (second and third grade of elementary school) with no reading disabilities, which have read one story in 13 paragraphs in a different font and background color. In the next phase, parameters will be measured (with the same set of sensors) during the reading process of children with dyslexia. The ultimate goal is to develop an application or sensor set that can quickly and accurately determine which color are suitable for an individual person, based on the value of the physiological measurements.
