中文摘要：

为了提高交互的自然性，提出用正交双目摄像机检测空间中的手指作为输入，引导全息影像显示的交互方法．在介绍交互原理的基础之上，分析了手指运动和像的变化，建立了两者的映射关系．在交互的实现上，通过计算全息预先得到场景的数字全息图序列，然后根据检测到的手指信息加载相应的全息图进行光电再现，即可达到数字全息光电再现实像的动态交互显示的效果．最后，孔雀全息再现像与人的交互实例验证了提出方法的有效性和可靠性．

英文摘要：

In order to improve the naturalness of interaction, an interaction method that uses finger detected by special orthogonal binocular cameras as an input of interactive system to guide holographic images display is proposed. After analyzing finger movement and images changes, an interaction relationship between them is established. For realizing the interaction, the digital hologram sequences should be acquired beforehand through computer-generated holograms, then the relevant holograms should be selected to reconstruct images according to finger information detected by cameras, eventually, the interaction between finger and opt-electronic reconstructed real images of digital hologram can be achieved. The proposed method is validated by an interaction between peacock images and people.
