随着通信技术的快速发展，智能终端不再仅仅是移动网络的终端，而是向着家庭网络扩展，使所有终端和互联网都能进行无缝链接，从而带来更广阔的发展空间。Android是Google推出的基于Linux平台的开源嵌入式操作系统。近年来，Android系统不仅在手机、平板中的市场比例不断上升，其开放性、兼容性、丰富的应用等的特点使Android在智能电视领域也得到重视。 采用先进的ARM Cortex A9处理器Hi3716H支持各种格式的高清晰度视频解码，提供音频/视频输入接口，3D加速引擎和标准的OpenGL ES 接口，Android2.0以上版本都是支持多点触摸的。因此本文提出了基于Android平台的多点触摸遥控系统开发设计方案，该方案基于Hi3716H处理器硬件平台和Android2.3版本软件平台。首先，深入分析了Android系统软件框架和应用程序结构。其次，系统通过智能电视USB驱动接收采用2.4G RF无线通信技术传输的触摸信息数据，然后上报给系统进行算法处理，通过分析触发事件时间序列上的坐标信息来确定手势具体的响应，实现多点触摸遥控操作。 本文介绍了智能电视操作系统和其人机交互的发展现状，针对现有操作系统和交互方式提出了以Android OS和触摸板为核心的系统解决方案，介绍了软硬件平台的搭建过程，将整个系统分为硬件层、数据接入层、驱动层、框架层、应用层及用户层六个层次，根据定义的核心手势和任务映射原则，提出了独立于触摸平台具有普适性的双指TDA手势识别算法，并给出了本地相册实例进行系统效果测试。最后对本文进行总结，提出了后续的研究方向。

With the rapid development of the communication technology, the Smart Terminal is no longer the terminal of Mobile Network .It turns towards Home Network and will realize the broader space for development, making all the terminals with the internet seamless connection. Android is the name of the open-source embedded operating system which is based on Linux OS. In recent years, Android has been continuously increasing Phones and Pads market share, and its open, compatibility, and the wide range of applications will make people pay more and more attention to Android in the field of Smart TV. With the advanced ARM Cortex A9 processor, the Hi3716H supports high-definition video decoding in various formats, providing audio/video input interfaces, 3D acceleration engine and standard OpenGL ES interface. Android supports multi-touch from version 2.0 onwards. So this paper presents a proposal of the Multi-touch Remote Control System based on the Android platform. It uses the hardware platform of the Hi3716H processor and the software platform of the Android 2.3. Firstly, deeply analyse the Android system software framework and application structure. Secondly, the system receives data of touch by 2.4G RF wireless communication technology via the USB driver of Smart TV, then report to OS for arithmetic processing. With analyzing the touch event of the coordinates information on the time series to determine the specific gesture of response and achieving multi-touch remote control operation. This article describes the current situation of smart TV operating system and its human-computer interaction, according to the existing operating system and interaction mode to put forward a system solution as the core of the Android OS and Touchpad. This thesis introduces the whole process on how to manufacture the hardware and software platform. The whole system is divided into the six levels: Hardware Layer, Data Access Layer, Driver Layer, Framework Layer, Application layer and User Layer, with the core gestures' action definition and tasks mapping principles, a universal touch screen independent TDA gesture recognition algorithm was put forward, and gives local albums application for the effect test. Finally, it summarizes and comes up with the subsequent research direction.
