“McSig”是一个多模式教学和学习工具，供视障学生与老师合作学习字形、笔迹和签名。它结合了触觉和音频输出，实现了教师的笔输入在并行的非视觉形式。McSig旨在教视障儿童如何手写字符（以及签名），这在没有视觉反馈的情况下非常困难。我们对8名视障儿童进行了评估，包括前测，以评估他们目前使用一组字符形状的技能，使用McSig的训练阶段，然后对相同的字符形状进行后测，看看是否有任何改进。孩子们都能使用McSig，我们看到他们画的字符形状有了显著的改善，特别是那些完全失明的孩子（他们中的许多人在测试前几乎不能画任何字符）。特别是盲人参与者都表示对该系统和使用计算机学习手写感到高兴和兴奋。
"McSig" is a multimodal teaching and learning environ-ment for visually-impaired students to learn character shapes, handwriting and signatures collaboratively with their teachers. It combines haptic and audio output to realize the teacher's pen input in parallel non-visual modalities. McSig is intended for teaching visually-impaired children how to handwrite characters (and from that signatures), something that is very difficult without visual feedback. We conducted an evaluation with eight visually-impaired children with a pretest to assess their current skills with a set of character shapes, a training phase using McSig and then a post-test of the same character shapes to see if there were any improvements. The children could all use McSig and we saw significant improvements in the character shapes drawn, particularly by the completely blind children (many of whom could draw almost none of the characters before the test). In particular, the blind participants all expressed enjoyment and excitement about the system and using a computer to learn to handwrite.
