中文摘要：
在多媒体教学过程中,教师容易受限于讲台,分发教学资料时学生轮流使用移动存储设备连接教学设备,效率低下,并且容易使某些病毒相互传播。为了保证教学质量,改善教辅工具,在分析了蓝牙无线技术、J2ME技术等相关技术的基础上,利用配备蓝牙模块的智能手机制作无线教辅工具,使用蓝牙手机无线控制PPT文件播放和无线批量传输文件。重点阐述了基于J2ME蓝牙无线技术的软件设计方案、实现中的关键问题和相应的解决办法,并进行了原型系统实验。实验结果表明：设计的软件不需要投入过多的成本便可实现移动手机控制多媒体教学,具有较高的应用价值。
英文摘要：
In the multi-media teaching process,teachers are easy to be subjected to the podium,when the students take turns to use teaching materials distributed and mobile storage device connected to the teaching equipment are inefficient and prone to spread certain viruses each other.To ensure the quality of teaching,improve teaching and tutoring tools,on the basis of analysis of the Bluetooth wireless technology,J2ME technology and other related technologies,smart cell phones equipped with Bluetooth modules are used to make wireless supplementary educational tool,Bluetooth wireless cell phone is used to wireless control PPT file playback and volume transfer files.Focusing on the key issues of implementary and corresponding solutions,the Bluetooth wireless technology,J2ME-based software design scheme.A prototype experiment is carried out.Experimental results show that the design of the software does not need too much investment to achieved mobile phone control multimedia teaching.It has high application value.
