摘要: 为打破传统虚拟电子书交互模式单一、只能左右挥动翻书的限制,设计了新的虚拟翻书交互模式。首先,对红外检测图像预处理后进行目标特征提取;接着,应用遍历搜索目标点算法提取手指点,实现手指点精确定位;然后将目标点位移信息映射成鼠标操作,进行创新虚拟翻书人机交互模式设计。最后,系统平台实现证明了该方法及新的交互模式能达到预期效果,并给出了张家港科技馆应用案例。

Abstract: In order to break down the mode of traditional virtual e-book which can only wave arm to turn pages, an innovative interactive mode of virtual e-book was designed. Firstly, the image captured by the infrared detecting system was preprocessed to extract target feature. Then, the traversal searching algorithm was used to extract the finger point and get its accurate position. Then, the finger point information was mapped into mouse driver, and the innovative interaction mode was implemented according to the offset of inter-frame finger point. New virtual e-book system platform was built to verify the algorithms and the interactive mode, and an application case on Zhangjiagang Science Museum was given.
