盲文识字率近年来有所下降,许多盲童现在在没有学习盲文的情况下长大。然而,学习盲文可以增加就业机会,提高识字技能。我们引入了盲文块,这是一个帮助视障儿童与视力正常的家长一起学习和练习盲文的系统。盲文块由一组有形的块和钉子组成,每个块代表一个盲文单元,以及一个与游戏相关的应用程序。该系统自动跟踪和识别这些块,以便父母即使不能阅读盲文也可以跟随。我们进行了一项用户研究,对五个家庭、五个父母和六个视障儿童进行了BrailleBlock测试。这项工作的贡献是盲文教育玩具的一种新方法,观察视障儿童和视力正常的父母如何共同使用这一系统,他们对盲文教育工具当前问题的见解,以及对未来基于盲文的学习工具的可行反馈。
Braille literacy has fallen in recent years, and many blind children now grow up without learning Braille. However, learning Braille can increase employment chances and improve literacy skills. We introduce BrailleBlocks, a system to help visually impaired children learn and practice Braille alongside a sighted parent. BrailleBlocks comprises a set of tangible blocks and pegs, each block representing a Braille cell, and an associated application with games. The system automatically tracks and recognizes the blocks so that parents can follow along even if they cannot read Braille. We conducted a user study to test BrailleBlocks with five families, with five parents and six visually impaired children. The contributions of this work are a novel approach to Braille education toys, observations of how visually impaired children and sighted parents used this system together, their insights on current issues with Braille educational tools, and actionable feedback for future Braille-based learning tools.
