摘　　要：手写试卷答题纸具有卷面信息长期保存和方便查卷取证的优点,在未来的很长一段时间内将仍然处于主流地位。但卷面信息难以信息化,导致信息化技术的优点无法在试卷管理上充分体现出来。针对笔试试卷卷面难以信息化的弊端,设计并实现了基于数码笔的数码答题纸原型系统。系统利用Maxell公司生产的数码笔,采集数码答题纸上留下的笔迹、所经过的X、Y坐标以及所在页码等参数来实现笔迹的还原,进而实现卷面信息化和部分客观题的自动判分的功能。经过实践测试,该系统能很好地实现上述功能。Handwritten test paper answer sheet has the advantages of long-term preserving the test papers＇ information and convenient paper checking and evidence gathering,so it would be still in dominant status during quite a long period in the future.However,due to incapable of informatisation in its paper information,the predominance of informatisation technology is not able to be fully materialised in test paper management.In this paper,a prototype digital answer sheet exam system based on digital pen has been designed and implemented in light of the flaw of handwritten test paper answer sheet in difficult to make informatisation.This system makes use of digital pen produced by Maxell Inc.and collects parameters including the handwritings left on the answer sheet,the coordinate X,coordinate Y which they traversed and the page numbers,etc.to realise the restoration of the handwritings,hence to implement the informatisation of test paper as well as the auto-marking function on part of the objective questions.After testing in practice,this system is proved to be good in achieving the functions described above.
