The Mind Connection - concept & possibilities

  1. 1. PROPOSAL FOR THE DEVELOPMENT OFA MULTI MEDIA NEURO FEEDBACK SYSTEMFOR USE IN THERAPEUTIC ENVIRONMENTS©THE MIND CONNECTION 2012
  2. 2. INTRODUCTION NEURO FEEDBACK THERAPY• Based on the registration and feedback of brainwave signals.• Measured with a user friendly wireless 14 channel headset.• Software analyzes the brainwaves and transforms them to soundsand visions.• As an induction the sound and vision feedback influences thesenses of the client.• This multi media induction is composed to direct the attention ofthe client to a desired state.The neuro feedback loop is closed and the client is training his attentionto cure his condition.
  3. 3. HARDWAREconnected to The Mind Connection software solutions (avaliable July 2012)Specifications of the Neurosky Mindwave headsetWeight: 90gSensor arm up: height: 225mm x width:155mm x depth: 92mmSensor Arm down: height: 225mm x width:155mm x depth:165mmRate power: 30mW (max. 50mW)RF frequency: 2.420 - 2.471GHzRF max. power 6dBmRF data range: 250kbit/sRF range: 10mPacket loss of bytes via wireless: 5%UART Baudrate: 57,600 BaudMax. signal input range: 1mV pk-pk EEGHardware filter range: 3Hz – 100HzResolution: 12 bits ADCSampling rate: 512HzeSense calculation rate: 1 Hz
  4. 4. HARDWAREpossible of getting connected to The Mind Connection software solutionsSpecifications of the Holst Centre Research Project Headset include:• Low-power (1 mW) multi-purpose sensor node• Wireless, low-power ECG patch• Body heat-powered EEG and pulse oximeter system• 2-, 6-, and 25-channel ExG systems• Wearable EMG belt• Wireless emotion monitoring system• BAN for sleep monitoring
  5. 5. HARDWARENumber of channels 14 (plus CMS/DRL references, P3/P4 locations)Channel names (International 10-20 locations) AF3, F7, F3, FC5, T7, P7, O1, O2, P8, T8, FC6, ,F4, F8, AF4Sampling method Sequential sampling. Single ADCSampling rate 128 SPS (2048 Hz internal)Resolution 16 bits (14 bits effective) 1 LSB = 1.95μVBandwidth 0.2 - 45Hz, digital notch filters at 50Hz and 60HzFiltering Built in digital 5th order Sinc filterDynamic range (input referred) 256mVppCoupling mode AC coupledConnectivity Proprietary wireless, 2.4GHz bandPower LiPolyBattery life (typical) 12 hoursSpecifications of the Emotiv Epoc headset
  6. 6. PRODUCT DESCRIPTION based on Emotiv Emoc• The base of the software is a network that transforms theinput of the brainwave signals of the headsetinto control signals for a multi channel sound engineand a real-time 3d-graphics engine.• The measured brainwave signals are stored for statistic reproduction• Neuro feedback training protocols can be created trough aseparate therapy editor.• The software can be encrypted to avoid software pirating

  8. 8. SOUND FEEDBACK• A number of selectable sound channels can be linked to the selectedtraining protocol.• State Sound compositions can be created, saved, loaded and playedtrough the Project menu. For example the Gaia State Sound composition ismade to induce a spectrum of nature sounds.• There are 8 stereo sound channels available.Every channel has 4 brainwave controllable sound effects:Filter – Reverb – Flanger – Echo.Screenshot of our actual State Sound application
  9. 9. SOUND FEEDBACKThe Mute buttons can be switched on and off to select one ormore sound channels for feedback.• Channel 0 responds to delta waves (campfire sounds)• Channel 1 responds to theta waves (wind sounds)• Channel 2 responds to alfa waves (water sounds)• Channel 3 responds to beta waves (cricket sounds)• Channel 4 responds to the train signal (bird sounds)• Channel 5 responds to the train signal (bell sounds)• Channel 6 produces a slow breathing sound.• Channel 7 produces an instruction voice.
  10. 10. 3D GRAPHICSOverview of the visual neurofeedback control parameters.Camera : Brainwave controlled multi directional camera animations.Colors : Brainwave controlled red, green and blue mixer.Shapes : Brainwave controlled décor and object animations.Particles : Brainwave controlled particle system animations.
  11. 11. 3D GRAPHICS• Screenshot of a 3D graphics scene from our actual State Visionapplication• A number of different scenes will be implemented inthe final version of the software
  12. 12. USER INTERFACE• Screen shot of the 3D graphics menu from our actual State Vision application
  13. 13. OPTIONS TO IMPLEMENT IN THE USER INTERFACE• Protocol selection• Difficulty level setting• Sensor contact test• Start/Stop + Save/Load brainwave filesExample Sensor contact verification on User interface levelThe Yellow dot indicates a poor signal connectionThe Red dot indicates a bad signal connection.
  14. 14. ANALYZE AFTER THERAPY SESSION• Graphs• Tables• Text• Database• Compare with previous sessions• User Data – client based personal data store
  15. 15. THERAPY DEVELOPER INTERFACE• Dual screen setup possibility• Selectable 3D-scenes• Selectable audio channels• Select what to control in the 3d-scenes and in the audio feedbackExample windows from our State Monitor applicationCreation of a number of protocols
  16. 16. Creation of control parameters:• Per sensor one or more frequency bands• Per frequency band: min freq, max freq, min level, max level,optimal level, or dynamics (change size + -)• Per sensor artefact detection and repression(muscle tension, eye movements, eye blinks)• Protocol decoding• Protocols for statistics feedbackDEVELOPER INTERFACE
