 +====== Introduction ======
 +The **//​Brainwave Visualizer//​** is a colorful, interactive application controlled by your brain, that shows you a graphical representation of your brain’s activity. The Brainwave Visualizer includes the Brainwave Visualization,​ Brainwave Power Spectrum Graph, and the eSense Attention and Meditation meters.
 +The on-screen shapes morph and change color depending on your state of mind. Because each person has a unique brain wave profile, no two visualizations will ever be the same.
 +====== Minimum System Requirements ======
  
 +^ ^ PC ^ Mac ^
 +^ Operating system | Windows XP/Vista | Mac OS X 10.5 Leopard |
 +^ Processor | Intel Core 2 Duo or equivalent ||

 +====== Starting the Brainwave Visualizer ======
 +To start the Visualizer, double-click the ''​Brainwave Visualizer''​ application icon on your Desktop (for Windows), or in your ''​Applications''​ (for Mac). The Visualizer will start up in a window and automatically attempt to connect to your headset, displaying the //Launch// screen while doing so.
 +
 +{{:​engineering:​applications:​brainwave_visualizer:​launch.png?​300|Launch screen}}
 +
 +If the connection attempt is successful, then you should see the //Welcome// screen.
 +
 +{{:​engineering:​applications:​brainwave_visualizer:​welcome.png?​285|Welcome screen}}
 +====== Configuring the Brainwave Visualizer ======
 +On startup, the Brainwave Visualizer will automatically try to connect to the headset. If this is unsuccessful,​ then a configuration panel will appear. You can also bring up this panel by pressing the **Esc** key on the keyboard.
 +
 +{{:​engineering:​applications:​brainwave_visualizer:​configuration.png?​300|Configuration panel}}
 +
 +Here, you can manually specify the port name as well as various other configuration options. You can also **enable demo mode**, which lets you run the Visualizer without a headset using randomly-generated data. On the Mac, you can determine your serial port name by following the instructions given in [[#Appendix A: Mac Serial Port Name]].
 +
 +===== Configuration Options =====
 +==== NeuroSky Headset ====
 +
 +^ Label ^ Description ^
 +| **Status** | This describes the status of the MindSet headset. The status is //​Connected//​ if the headset is connected to the computer and the application is communicating successfully with the headset. The status is //​Disconnected//​ if the headset is disconnected from the computer. |
 +| **Port** | This option tells the application which serial port to look for the headset on. |
 +| **Scan ports** | This option enables or disables the port-scanning function when a connection attempt is made. |
 +| **Enable demo mode** | This option turns on demo mode, which lets the Visualizer operate without the headset (using randomly-generated data). |
 +
 +==== Visualizer ====
 +^ Label ^ Description ^
 +| **Show axes** | This option enables or disables the display of the radial axes shown in the dynamic visualizer. |
 +| **Enable full screen mode** | This option turns on full-screen mode, which causes the Visualizer to occupy your entire screen. |

 +====== Interface ======
 +The Visualizer contains several interface elements that are common to the different views built in.
 +
 +{{:​engineering:​applications:​brainwave_visualizer:​interface_overview.png?​300|Interface overview}}
 +
 +^ ^ Name ^ Description ^
 +^ 1 | View selector | This lets you select between the available views. The selector only appears when you move the mouse cursor. It disappears if the keyboard and mouse have been idle for long enough. |
 +^ 2 | Signal status | This tells you the quality of the brainwave signal coming from the headset. A red **X** means that the headset is disconnected. The more bars there are, the better the signal quality. Generally, a status with four or five signal bars indicates a good signal. |

 +====== Views ======
 +The functions of the different views are explained in the sections below.
 +===== Chart View =====
 +The first view you see when you start up the Visualizer is the **Chart View**, which consists of the Dynamic Brainwave Visualization,​ the Brainwave Power Spectrum Graph, and the eSense(tm) Attention and Meditation meters. The Chart View provides a comprehensive display of all the data coming from your headset.
 +
 +{{:​engineering:​applications:​brainwave_visualizer:​display_mode.png?​300|Chart view}}
 +
 +<​note>​
 +The Chart View contains an **//​interactive help feature//​**. Click on each of the various components to bring up an informative description of that component, along with voice narration.
 +</​note>​
 +
 +===== Dynamic View =====
 +The **Dynamic View** of the Visualizer emphasizes the gently flowing shape of the dynamic visualizer component. You can use the **left** and **right arrow keys** to change the look and characteristic of this shape.
 +
 +{{:​engineering:​applications:​brainwave_visualizer:​dynamic_mode.png?​300|Dynamic view}}
 +
 +<​note>​
 +Try playing some music while running the Visualizer in this mode. You may see some unique shapes and colors that are generated by actively listening to a particular track!
 +</​note>​
 +
 +===== Game View =====
 +The **Game View** of the Visualizer lets you play a simple telekinetic game that utilizes eSense(tm) values from the headset. You can hold down and drag the **right mouse button** to change the perspective of the camera. Buttons on the left side of the screen let you choose between eSense(tm) Attention and Meditation. The data shown in the top-left portion of the screen helps you keep track of various game statistics. The bar at the bottom tells you your current level of Attention or Meditation.
