现代社会人们生活质量的提高,人们对于智能摄像设备的要求也逐渐的提高，对于智能摄像设备的功能,人们已经不仅满足于摄像设备本身能拍出高清晰度的照片或视频。为了满足人们对于大屏幕高清晰度显示的需求，微投影摄像机应运而生。然而，现在市面上销售的带有投影功能的摄像设备，只能做到用投影出的大屏幕播放，但是想要对投影出的界面进行操作，还是要去使用摄像设备本身的按键进行操作，这就给用户的使用带来了限制。本论文主要研究内容就是为智能摄像设备投影功能寻找更加自由，在与投影界面交互时，对用户限制更小的交互方式。手势交互就非常适合于这一使用情境，手势交互具有自由、直接、快捷、易学习的特点，这非常适用于智能摄像设备的投影功能，可以帮助用户解决现阶段操作受限制的问题，让用户可以自由而便捷的对投影界面进行操作。本文的主要研究内容如下：通过桌面研究和问卷调查的方式，对微投影摄像设备进行研究，发现市面上在售设备的优缺点、用户接受程度，以及用户对于摄像设备投影功能的使用痛点和交互偏好。通过实际观察和访谈更深层的挖掘用户的使用痛点和需求，通过不同形式的访谈研究目标用户的行为习惯和交互偏好，探索更适合于摄像设备投影功能的交互方式，如：手势交互。通过对之前调研结果的转化和分析，提炼出了满足用户需求的设计准则，并根据设计准则设计出了一套与摄像设备投影界面相配套的手势动作，以及实现手势交互所需要的原型。制作出真实的原型，并对它进行了评估与测试，验证设计的手势交互是确实可行有效的。

With the improvement of people's quality of life in modern society, people’s requirements for smart camera devices are gradually increasing. For the functions of smart camera devices, people are not only satisfied that the camera devices can shoot high-resolution photos or videos. In order to meet people's demand for large-screen high-definition display, micro-projection cameras came into being. However, the camera equipment with a projection function currently available on the market can only be played on a large screen that is projected. However, if you want to operate the projected interface, you still have to use the buttons on the camera itself to operate. This imposes restrictions on the use of the user. The main research content of this thesis is to find more freedom for the projection function of the intelligent camera device, and to interact with the projection interface, the interaction mode with less restrictions on the user. Gesture interaction is very suitable for this use situation. Gesture interaction is free, direct, fast, and easy to learn. It is very suitable for the projection function of smart camera equipment. It can help the user to solve the problem of limited operation at the current stage. It is free and easy to operate the projection interface. The main research contents of this article are as follows: Through desktop research and questionnaire survey, the microprojection camera equipment is studied, and the advantages and disadvantages of the equipment on the market, user acceptance, and the user's use of the projection function of the camera equipment are identified. Preferences. Through actual observations and interviews, users are more deeply digging through the use of pain points and needs, through different forms of interviews to study the target user's behavioral habits and interaction preferences, and to explore ways of interaction that are more suitable for the projection function of camera equipment, such as gesture interaction. Through the transformation and analysis of the previous research results, the design criteria satisfying the user's requirements were extracted, and a set of gesture actions that matched the projection interface of the camera equipment was designed according to the design criteria, and the prototype needed for the gesture interaction was designed. A true prototype was produced and evaluated and tested to verify that the gesture interaction of the design was indeed feasible and effective.
