We built a multimodal biofeedback system integrated with low-cost sensors and applied the system to support meditation training utilizing multimodal biofeedback to the user. Our meditation support system employs Electroencephalogram, heart rate variability and eye tracking. The first two biosignals are employed to assess the mental stress during meditation, and eye tracking is equipped to detect an interval where the user engages in meditation by monitoring the open/closed states of the eyes.
