How are the different parts synchronized?

The EMDR Kit Wireless is designed to provide a cohesive experience across visual, tactile, and auditory channels. To ensure the stimulation feels natural and consistent for the client, the Pulsators and Headphones are precisely timed to the movement of the light dot on the Light Tube.

This synchronization is a key feature of the EMDR Kit, as it ensures that the tactile and auditory signals align with the visual tracking of the light. This creates a balanced multi-sensory environment, which is particularly useful during high-intensity Working Memory Taxation (WMT) or standard desensitization phases.

The "Middle Point" Synchronization

The timing of the Pulsators and Headphones is triggered by the position of the light dot relative to the center of the Light Tube. The synchronization works as follows:

• Moving to the Right: As soon as the light dot passes the exact middle of the Light Tube and moves into the right-hand side, the right Pulsator will pulse. The Headphones will play a sound at the right end side. 

• Moving to the Left: As soon as the light dot passes the middle and moves into the left-hand side, the left Pulsator will pulse. The Headphones will play a sound at the left end side. 

Why the Middle Point?

The logic behind this synchronization is based on the moment your eyes cross the midline. When your eyes move from the left side, through the middle, and toward the right, the other stimuli trigger to match that shift in focus. This ensures that the tactile and auditory signals are received in the brain at the same time as the visual stimulation.

Customization: Using Different Speeds

While synchronization is the standard setting, you also have the option to set the speeds of the Pulsators or Headphones individually, independent of the Light Tube. This "de-syncing" allows for a more complex sensory experience if required by your specific protocol.

To set an individual speed:

1. Enter the Submenu: Tap on the Pulsator or Headphone icon in the app.

2. Toggle Individual Speed: Activate the option labeled "Use different speed."

3. Adjust the Slider: You can now manually set the speed for that specific component without affecting the Light Tube's rhythm.

Impact of Speed on Synchronization

While the trigger always happens at the middle point, the exact duration of the vibration or sound can vary based on the speed selected in the app:

• At Higher Speeds: Because the light moves faster across the tube, the pulse and sound are adjusted to maintain a consistent rhythm with the visual sweep. The Pulsations are shorter. 

• At Lower Speeds: Because the light dot moves slower, the pulsations are longer.

Regardless of the speed, the EMDR Kit app automatically calculates these timings so that the hardware components always remain perfectly in sync.
