摘要
从古到今,人类从未停止过寻求知识和探索真理的脚步;记录和阅读作为求知的一种手段亦是由来长久,从遥远的壁画或是简牍到现在的纸本书卷,阅读已经成为人类学习生活的重要部分。随着技术的发展,尤其是当代电子产业和计算机技术的日新月异,阅读的媒介和方式也发生了翻天覆地的变化。传统的记录媒介通常是笔墨以及纸张,阅读方式是单一的人手一本书地阅读,传统意义上的图书馆也仅仅是大的物理书本的集合以及分类呈现。而随着大型展示屏幕,便携式平板电子产品以及三维动画技术等的使用,阅读方式变得丰富多彩起来;图书不仅文字的表现,更辅以多媒体的表现媒介以及2D,3D的图形模型;阅读和记录的交互方式也多样化起来,不仅可以虚拟化模拟现实阅读,也可以辅助增强阅读以及记录的体验。
     本文依靠CADAL已有的电子图书资源,在特有硬件的支持下研究在特定环境下如何增强用户体验以及实现阅读平台,主要工作包括:
     第一,对于在大屏幕显示器的依托下的阅读展示平台CReader,设计实现该系统的两个模块,包括设计实现新型的图书内容融合与展示模块,即设计实现跨媒体图书阅读;以及利用Kinect设计实现系统中的姿势交互,并介绍相关关键技术。
     第二,在深度摄像头Kinect的支持下,实现基于传统阅读方式的电子笔记自动生成系统D-Note。该系统支持传统的物理书的阅读,通过获取和分析深度图像信息和彩色图像信息,以及获得的指尖轨迹信息生成电子笔记。
Past and present, human never stop their steps heading on seeking for knowledge and employing the truth. As one of the methods for seeking knowledge, writing and reading has a long history too. From fresco and bamboo slips which are old-age to paper books now, reading has become one important part of our studying live. With the development of technology, especially the rapid development of contemporary electronic industry and computer technology, the medium and way of reading have great change too. Traditional recording mediums include pen and paper, the traditional reading is just one person keep one book, the library in traditional sense is just collections and classification and the finally present of books. But now, by using the large display, pad, and phone, reading becomes rich and colorful, not only including the present of text, but also including the present of multimedia and 2D images,3D models. The interaction becomes rich too, not only including virtual presentation of the traditional books but also including real time interactions which trigger the auxiliary functions.
     Using the digital books in CADAL, we research how to implement reading systems under different conditions and different hardware support. We mainly do work in three aspects.
     Firstly, perfect the reading system CReader, which under the support of the touched large display, and enhance its user experience. We discuss how to design and implement the cross-media book and pose interaction with the support of Kinect.
     Secondly, with the support of Kinect, we design a digital note taking system D-Note. D-Note supports traditional reading with physical books, meanwhile output digital note through analyzing depth image and color image and the tracks of fingertip. Here we will discuss the detail workflow and key technical.
