INTRODUCTION
Resource for Education
Use of Assistive Technologies for Deaf Education;
Iterative Elements as a Encouragement to Learning;
Use of visual elements and the Brazilian Sign Language (Libras) .
OBJECTIVES
Investigation of Accessibility Standards in Educational Games for Deaf Children available on the Web.
GENERAL DESCRIPTION
Survey of accessibility standards in developing assistive technologies;
Evaluations of Usability, Acessibility and Pedagogic Aspects;
Results use for evaluation and developing of Game named Conceitos (Concepts), in progress in the research group.
MATERIALS AND METHODS
WCAG 2.0 Plataform
Analysis of its own documentation;
Bibliographic review of papers developed around it.
MATERIALS AND METHODS
Definition of User Profile.
Raised by the use of Personas (definition of users - characteristics and objectives in the system).
Deaf Children;
Start of elementary school;
Literate in Libras;
Use images for understanding concepts.
MATERIALS AND METHODS
“Multi–Trilhas”
Developing:
Laboratório de Pedagogia do Design (LPD) – PUC - Rio de Janeiro
Departamento de Artes & Design – PUC - Rio de Janeiro
Instituto Nacional de Educação de Surdos do Rio de Janeiro
Availabe in: www.multi-trilhas.com
MATERIALS AND METHODS
Multi–Trilhas aims to promote:
Ways; Actions; Repetitions; Displacements; Concepts;
Reasoning; Interation; Decision Making; Acquisition of
Second Language (Written Portuguese).
MATERIALS AND METHODS
“LIBRAS: Brincando e Aprendendo”
Classroom learning concepts like math, science, geography and portuguese;
CrossWords, as support the learning of written Portuguese, with assistance of animations in Libras;
Available in: http://www.librasnet.com.br/shockwave/menu/menu.html.
MATERIALS AND METHODS
WCAG 2.0 plataform.
Intends to attend 4 attributes :
Perceptible –Find the action;
Operating – Do the action;
Understandable - Understand the action;
Robust – Make possible the action.
Multi-trilhas Evaluation (Perception) Missing of description of various components;
Does not maintain information on Libras in the game as a whole;
Lack of zooming
LIBRAS: Brincando e Aprendendo Evaluation (Perception) Interface could be better organized;
Does not maintain information on Libras in the game as a whole;
Lack of zooming
RESULTS OBTAINED
Avaliação Multi-trilhas (Operability) Not supported via keyboard and change of focus via tab;
Identify Current Page;
Viability of other ways of interaction.
Avaliação LIBRAS: Brincando e Aprendendo (Operability) Not supported via keyboard and change of focus via tab;
Identify Current Page;
RESULTS OBTAINED
Multi-trilhas Evaluation (Understanding) Lack of help documentation or tutorials demonstration;
Identification of errors.
Avaliação LIBRAS: Brincando e Aprendendo (Understanding) Lack of help documentation or tutorials demonstration;
Identification of errors.
RESULTS OBTAINED
Identification of guidelines that assist Deaf therefore fixes mostly intended for visual components.
Its necessary to emphasize the lack of components in Libras accompanying the user in his interaction as a whole.
CONCLUSION
Possible solutions suggested:
Zoom Tools;
Page Identification;
Interface descriptors in Libras;
Interation Errors well signposted.
CONCLUSION
Raise barriers that prevent the interaction of a deaf user;
Setting standards that minimize these barriers raised.
