Study uses wearable device to monitor children's screen time


In 2016, researchers at MIT developed a wristband device to automate tracking screen time based on an off-the-shelf colour sensor used to calibrate colour and brightness in TVs and other screens and a learning algorithm that could detect when a screen was nearby. The device was intended for use in a clinical study at Massachusetts General Hospital aiming to understand how children's behaviour contributes to health issues such as high blood pressure, diabetes, and obesity; the wristband will also contain other sensors that monitor physical activity and sleep.
