A Preliminary Study to Develop a Lightweight Biofeedback Device for Reading Activity

摘要

It's widely known that concentration can help to improve one's reading speed and efficiency. In previous researches, we found that concentration of the participants who were carrying out intellectual activities would be increased when we applied brainwave-based biofeedback to them, and the time they spent on current activities would also be prolonged. As the brainwave sensor is susceptible to interference and difficult to wear for a long time, we want to find a new method to get engagement levels by using the sensors which can be equipped to existing wearable equipment, and design a simpler biofeedback system excluding the measurement of brain waves for lightweight devices for reading. In experiment, each participant was requested to perform a 30-minute reading task 10 times. In the meantime, we measured their brain wave, heart rates and skin conductance. The visual analog scale (vas) was used to measure the degree of comprehension, the interest in the book, and the subjective engagement level at that time.
