How to use Shadow feedback

Start the data stream before starting the shadow.

Select design settings

Open the design. Then set controls for the design (play or record, client, design setup, etc.).

Select Shadow as feedback type and open the shadow panel to select settings but do not start the shadow until the data stream is flowing.

Select shadow settings

Use the light/dark icon to open the shadow panel. In the shadow panel under “Source” you may select to have the shadow range based on the number of targets met (brighter as each additional target is met) or continuous ratios. Select the one that best suits the design and training that you are doing at the moment.

Start the session

When the client is ready to begin, start the session using the Play/Capture button.

Start the shadow

Once the data stream is started click the “Start shadow” button. The shadow window should appear. Now you can resize it or maximize it to full screen.

Fix shadow to start feedback

Tick “Fix shadow” to start the shadow feedback. This will lock the shadow into the place and size that you have selected and allow you to click on anything behind the shadow.

If you are using only a single monitor for training, instead of the “Fix shadow”, click the clock icon. That will give you 5 seconds to place and resize the shadow, after which it will become fixed. Otherwise, if not fixed, the feedback will not begin and you will not be able to select anything behind the shadow.

For feedback control of volume, tick the Volume box. Use the “Min volume” slider to change the amount of change heard (left is more change; right is less change).

To adjust the general volume of the Brain-Trainer feedback and not the computer’s other sounds, use your computer’s Volume mixer. To open the Volume mixer, RIGHT-click on the speaker icon at the bottom right of your screen. Move the slider for BioEra.

When the design stops, you may find the shadow is no longer fixed/active. If the shadow is in the way of your controls, close it by hovering your cursor over the Shadow window in the task bar and clicking the X.

Feedback source selections

Met targets

This choice will give feedback based on the number of thresholds that are being successful at each moment. Let’s say you are training with FRE% which has 2 threshold bars. If the two targets are met, the screen will be totally clear/bright. If one of them is met and the other one is not, the screen will be partially shaded (half of the maximum intensity). If no thresholds are met, the screen will get dark (maximum intensity set on the slider). This method shows the brain how much it is achieving the desired results.

Continuous ratios

For each threshold, the current measure is divided by the threshold value. This number is inverted if it’s an inhibit threshold. The results of all thresholds are averaged and sent to the shadow. In summary, this method will reflect every change that occurs on the amplitudes of the bands that are being trained. It works as a mirror to the brain.

Continuous ratios may be the best option in many cases, but the trainer can decide otherwise when desired.

In the current version, continuous ratios is sometimes crashing the shadow program. That makes the shadow get completely dark. The corrections to that have already been implemented in the very next version that is about to be released.
