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

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

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.
