Open Source EMDR Machine. The Whole Blog.
This blog post describes steps to use the machine and has a prototype run video. There is still a lot to do.
Machine view
Right now all the parts are connected by simple wires and I will be working on adding connectors and nice expandable double wires.
In this case all the part can be set up around the room conveniently for the therapist and the client.
This is how machine is looking now:
There are also software issues, for example refresh speed issues with BLE - with higher refresh speed BLE stops working. Software cannot be deployed on Android yet.
I will be fixing this issues too.
Prototype functionality description
But overall machine will work like this:
First, user is giving 2 options: to run EMDR machine on Arduino, or on PC/Android.
If user selects Arduino - he then see additional options: to scan for BLE devices and connect to "EMDRArduino" device.
For both options user can select to use Light and Sound for bilateral stimulation.
For Arduino option user can select Small tappers - to hold in hands or Large tappers (both are vibration motors) - to be put on chest.
Then user click Preview and machine starts.
For Arduino version user can change:
Speed of stimulation. For example, stimulation makes the whole circle in 1 second, or 4 seconds.
Brightness and Color of Light.
Sound and Tappers are triggered when Light is less than 1/3 from the edge of the light bar. Sound is 440Hz, concert A frequency. I think it is the most pleasant to a human ear.
User can always press Back button and adjust Light/Sound/Tappers settings.
For PC/Android part user can see Light/Sound options. After selecting one or both and clicking Preview the stimulation tarts on the screen.
User can adjust Speed, Size of the ball and Color of the ball. Then User can go Full screen (black screen with ball moving in the middle) so options panel does not distract his client.
And he can always go back and adjust the options.
