R.A.D.A.R. Method


In our Reading Center for Learning and Reading Difficulties of Emmetropia, a multi-disciplinary group of scientists and doctor, will conduct a full assessment for all types of reading or learning difficulties, which includes: an ophthalmologic assessment, an optometric assessment, a hearing assessment, an assessment by a child-psychiatrist and assessment by a special educator. All the aforementioned assessment in correlation with the R.A.D.A.R. Method is the most complete assessment for learning and reading difficulties.

R.A.D.A.R. Method is fast, objective and has measurable results with high reproducibility. The R.A.D.A.R. method is applied in an entirely standardized manner to all individuals, enhancing the reliability measurement. Timing and presentation speed of the stimuli can be controlled precisely. In addition, R.A.D.A.R. is much faster than conventional tests. The results can be compared with any pre or post assessment. Moreover, the diagnosis is objective because it is based on reading parameters, namely, fixation duration and saccadic length. The final outcome of the diagnosis cannot be affected by external factors, such as the subjective judgment of the test administrator.

No expertise or prior knowledge is required. Basic computer and communication skills are the only prerequisites for the administration of R.A.D.A.R. The method is straightforward and is designed to be used by easily administrated by professionals coming from a variety of different backgrounds. Due to the examination method’s simplicity and the automatically generated results report, there is no need for highly trained personnel. The reader’s performance results and the graphical patterns will be generated automatically and no prior training would is required for the reading of the results. This fact reduces the cost of the evaluation.

Various additional reading characteristics are used for the diagnosis. R.A.D.A.R. uses video-based eye-tracking, a technology applied in computer science for research and marketing purposes. With R.A.D.A.R., the reader’s reading characteristics can be thoroughly analyzed, with accuracy of milliseconds. The information exported can be used for the diagnosis of reading abnormalities and difficulties both in children and adults. Fixation and Saccade characteristics, such as means, standard deviations, fitting parameters, along with Ex-Gaussian distribution parameters are being measured.

R.A.D.A.R. provides specialized information for a customizable treatment by therapist. After thorough analysis of the results, the most common mistakes during test reading, as well as other processing deficits that might cause a problem to the reading process of the individual, would be identified within the capabilities of R.A.D.A.R. This knowledge is made available to the therapist who then can choose the appropriate personalized treatment. After a certain period, the individual can be re-evaluated using the initial or an updated reading test. The R.A.D.A.R. method is able to evaluate the progress of the individual’s reading maturity over the years, using its standardized procedure.

The results are reproducible. The R.A.D.A.R. method had been tested on two consecutive evaluations of the same individual with 10-15 days' intervals. This time period is short for any developmental changes on the individual. There was no significant difference between these two evaluations, indicating that R.A.D.A.R.’s results are reproducible for the same reader.

Eye Tracking

Eye Tracking is the process of recording the eye movements using a detector (an Eye-Tracker). The detector traces two characteristics of the eye: the cornea reflexion and the eye pupil. Read More
