Abstract
Handwriting remains an essential skill, particularly in education. Therefore, providing visual feedback on handwritten documents is an important but understudied area. We outline the many challenges when going from an image of handwritten input to correctly placed informative error feedback. We empirically compare modular and end-to-end systems and find that both approaches currently do not achieve acceptable overall quality. We identify the major challenges and outline an agenda for future research.

手写仍然是一个重要的技能，特别是在教育领域。因此，在手写文档中提供视觉反馈是一个重要但研究不足的领域。我们概述了从手写输入图像到正确放置的信息性错误反馈之间存在的诸多挑战。通过实证分析模块化系统和端到端系统的差异，我们发现目前这两种方法都无法达到令人满意的总体质量水平。我们识别出了主要的挑战，并为未来的研究制定了议程。
