EMOTIV EPOC USER MANUAL | BRAIN COMPUTER INTERFACE TECHNOLOGY
3.1.3 EmoKey
EmoKey links the Emotiv technology to your applications by easily converting detected events into
any combination of keystrokes. EmoKey is a nonintrusive, lightweight, background process that
runs behind your existing games or applications. EmoKey lets you create mappings that define how
detections are converted to keystroke combinations. Your mappings can then be saved and shared
so you can use mappings that your friends have created for your favorite games and software.
EmoKey mappings can be as simple as linking the Expressiv smile detection to text characters
such as ":)", so that chat applications instantly know when you smile.
Configuring EmoKey
To configure a facial expression to EmoKey, select the expression you wish to link and click on the
Key
button next to the Facial Expression description. This will bring up a Configuration Dialogue
box as shown in Figure 7. Type into the text box, the specific keystroke(s) you wish to send. You
can also make the facial expression send a continuous string of keys by checking the
Hold the key
box.
There are also options to further configure the
Key hold time
and
Key trigger delay time
. Once you
are satisfied with the settings, click the
Apply
button.
