There is nothing complicated going on here. Wekinator expects incoming data on a specified OSC port. The Myo broadcasts websocket events with data from its sensors. Myow simply listens for the websocket data using myo.js and translates them to appropriate OSC messages using osc.js.
Basic instructions below, and checkout the basic tutorial.
Install the package globally via npm:
$ npm install -g myow
Note: myow requires Myo Connect to be running.
Look at the help output:
$ myow --help Usage: myow [options] [input] Send data from Myo to Wekinator. Input value can be one of [accelerometer|orientation|gyroscope|emg|imu] (default: imu) Options: -h, --help output usage information -V, --version output the version number --outhost [value] The host on which to send OSC data (default: 127.0.0.1) --outport [n] The port on which to send OSC data (default: 6448) --inhost [value] The host on which to receive OSC data, if --receive-osc argument is present (default: 127.0.0.1) --inport [n] The port on which to receive OSC data, if --receive-osc argument is present (default: 12000) -r, --receive-osc If present, listen for OSC messages on --inport -l, --log Log osc in/out to console. --login Log osc input only to console. --logout Log osc output only to console.
The [input] value lets us specify what stream of data to pass along to Wekinator. By default, it will use
imu, which is a 10-dimensional vector composed of accelerometer, gyroscope, and orientation data. You can narrow down that data stream by specifying
orientation as the input. If you wish to use raw 8-dimensional EMG data, use
emg as the input.
If you're not using the default hosts/ports in Wekinator, you can use the optional arguments to set custom values.
Start sending OSC messages containing all imu (inertial measurement unit) data to
/wek/inputs using the default ports with no input/output logging:
The imu data looks like:
[ -0.52392578125, -0.0126953125, 0.76611328125, 8.1875, 81.1875, 3.0625, 0.59625244140625, -0.19793701171875, 0.16851806640625, 0.75946044921875 ]
Maybe we only want to use orientation data and log all outgoing OSC messages:
$myow -l orientation
Then we'll be sending only the last four elements of the imu data along:
[0.59625244140625, -0.19793701171875, 0.16851806640625, 0.75946044921875 ]
Logging OSC messages
It can be helpful to inspect the stream of messages that are being sent and received via OSC. You can use
-l to view input, output, and both message types, respectively.
By default myow will not listen for incoming OSC messages, so as not to interfere with any other applications you have set up to handle output from Wekinator. If you with to inspect what Wekinator is sending out, you can tell myow to receive OSC using the
$ myow --login -r orientation
