Proved by special education teachers

In University of Tallinn Institute of Educational Sciences Department of Special Education has made a research with title “3D color pages prototypes usability testing and product conducting feasibility” on 2015.

Master’s thesis research based from the company’s Universal Design head Hiie Härm referral to the University of Tallinn, to the aim to conduct anationwide study that tests for the blind and partially sighted children drawn elevated (1-1.5 mm) lines in the 3D color pages as study material. The final goal is a maximum product development, which based on 3D colouring pages tested by teachers and special education teacher’s opinions and suggestions. The worksheets are completed handcrafted in the Estonian people with disabilities in the work center Juks, and therefore the 3D pages lines may be uneven. “3D colouring pages prototypes usability testing and product conducting feasibility” is a registered TÕA 15008A project of the University of Tallinn.

The project “3D color pages prototypes usability testing and product conducting feasibility” was carried out in co-financing from the European Regional Development Fund. The project received support from the Innovation Voucher EAS support measure.
Master’s thesis is designed to test the prototypes of 3D color pages to assess their feasibility and usability for develop visually impaired children. Master thesis tasks: 1) to give a theoretical overview of the target group which is designed for 3D colouring pages. 2) to involve of teachers to test the 3D color pages, who teach children with sp
ecial needs. 3) to carry out a thematic questionnaire for professionals. 4) to analyze the results of testing 3D color pages usability.
The research method is a semi-structured questionnaire survey which was carried out in Tallinn,Tartu, Pärnu, Narva and Kohtla-Järve during March a nd April 2015 and got responses to a total of 18 teachers and special education teachers in schools (2) and kindergartens (9).
Master’s thesis consists of three chapters: The first chapter describes the development of a child with special needs, the second chapter describes the study methodology and the third section analyzes the results obtained in the study of the 3D colouring pages for visually impaired children in developing usability and practicality.
The research revealed that the 3D color pages are a good learning material which helping to develop the child motor skills, perception, attention, vocabulary and storytelling skills, thanks to heightened sense contour shape of the objects in the picture. The teachers and special education teachers experimented with 3D color pages with children in different ways. Their instruments were: pencils, paints, modeling clay, clay, wax, pastels, water colors, crayons and soft plasticine (Play Dough).


The project “Using 3D colour sheets testing and analyzing” was carried out
between 23.01.2015 and 20.07.2015 and it was funded by the Enterprise Estonia (EAS).
