* What data does emokit give me? |
|
|
5 |
|
|
|
6 |
The raw channels of the headset |
|
|
7 |
|
|
|
8 |
Battery power of the headset (in development at time of FAQ writing) |
|
|
9 |
|
|
|
10 |
Signal quality of each connection on the headset (in development at time of FAQ writing) |
|

|
|
12 |
* What data does emokit not give me? |
|
|
13 |
|
|
|
14 |
Processed data that can tell you moods or muscles or whatever. |
|
|
15 |
|
|
|
16 |
Basically, if you aren't up to doing a bit of DSP and aren't really |
|
|
17 |
educated in mathematics and neuroscience, you should use emokit under |
|
|
18 |
another library that will do the geekery for you. We publish emokit as |
|
|
19 |
a low level access tool, nothing more. |
|
|

|
|
|
21 |
* Does emokit work with all emotiv headsets? |
|
|
22 |
|
|
|
23 |
As far as we know, yes. If it doesn't work with yours, file an issue |
|
|
24 |
on the github project (http://github.com/openyou/emokit/issues) |
|
|
25 |
|
|
|
26 |
* I heard you need to know your key or something? |
|
|
27 |
|
|
|
28 |
That doesn't apply anymore. Emokit should work with all headsets and |
|
|
29 |
dongles. If it doesn't, file an issue (http://github.com/openyou/emokit/issues). |
|
|
30 |
|
|
|
31 |
* So I really don't need to know my key or whatever now? |
|
|
32 |
|
|
|
33 |
You shouldn't. It should "just work". So please stop asking. |
|
|

When emokit first came out (For more information on this, check out |
|
|
38 |
Announcement.md in the doc directory), we only knew part of how the |
|
|
39 |
encryption worked, mainly because Daeken finished the first round, |
|
|
40 |
qDot took things over, and then neither of them had time to do |
|
|
41 |
anything for a while. So there was a lot of news that went around of |
|
|
42 |
"only certain headsets/keys work", so on and so forth. |
|
|
43 |
|
|
|
44 |
We managed to get lucky with the method for a while, because Emotiv |
|
|
45 |
was reusing keys on USB dongles, so one key would work for many |
|
|
46 |
headsets. Once Emotiv learned of this, they just had to switch out the |
|
|
47 |
firmware flashing on their keys, and emokit no longer worked. |
|
|
48 |
|
|
|
49 |
In late 2011, Daeken finished the key generation code, which means |
|
|
50 |
emokit should now work for any USB key. Note that the encryption |
|
|
51 |
happens on the USB KEY, not the headset. So it's actually tied to |
|
|
52 |
whatever you have plugged in regardless of the headset. |
