java程序获取MindWave Mobile 2脑波耳机数据+二次开发
初始代码包下载：链接：https://pan.baidu.com/s/1nEb5kmk8PabkFmK3bO8Fww
提取码：r5pu
解压后用eclipse打开该项目
在src中建立名字为lib的package，
讲这三个.jar文件复制到lib下
导入jar文件方法如下：
大致的目录结构如下：
然后修改brainkeyboard.java代码为：

| * @author Andreas Borg, borg@elevated.to | |
| * @modified June, 2011 | |
| * @version 1.0 | |
| * | |
| * | |
| * This library is following the same design as the one developed by Jorge C. S. Cardoso for the MindSet device. | |
| * The MindWave device can communicate to a socket over JSON instead of the serial port. That makes it easier and tidier | |
| * to talk between the device and Java. For instructions on how to use the callback listeners please refer to | |
| * | |
| * http://jorgecardoso.eu/processing/MindSetProcessing/ | |
| * | |
| * | |
| * Data is passed back to the application via the following callback methods: | |
| * | |
| * | |
| * public void attentionEvent(int attentionLevel) | |
| * Returns the current attention level [0, 100]. | |
| * Values in [1, 20] are considered strongly lowered. | |
| * Values in [20, 40] are considered reduced levels. | |
| * Values in [40, 60] are considered neutral. | |
| * Values in [60, 80] are considered slightly elevated. | |
| * Values in [80, 100] are considered elevated. | |
| * | |
| * public void meditationEvent(int meditationLevel) | |
| * Returns the current meditation level [0, 100]. | |
| * The interpretation of the values is the same as for the attentionLevel. | |
| * | |
| * | |
| * public void poorSignalEvent(int signalLevel) | |
| * Returns the signal level [0, 200]. The greater the value, the more noise is detected in the signal. | |
| * 200 is a special value that means that the ThinkGear contacts are not touching the skin. | |
| * | |
| * | |
| * public void eegEvent(int delta, int theta, int low_alpha, int high_alpha, int low_beta, int high_beta, int low_gamma, int mid_gamma) </code><br> | |
| * Returns the EEG data. The values have no units. | |
| * | |
| * | |
| * | |
| * public void rawEvent(int []) | |
| * Returns the the current 512 raw signal samples [-32768, 32767]. | |
