It only takes a small function of Apple Watch to prevent car accidents.

Today's connected cars try to provide many safety features, such as using radar and cameras to detect imminent accidents, and sometimes even taking over brakes and steering controls to prevent the accident. At the very least, cars will issue increasingly loud visual and sound alerts to enable drivers to take action to avoid accidents.

Although this system provides good assistance to the driver, will the effect be counterproductive and reduce the driver's safety vigilance? Recently, a new study of the school of engineering has raised such questions.

Researchers say the problems of these systems (also known as advanced driver assistance systems, ADAS) can be classified into two categories: alarm fatigue and short distraction.

However, adding a simple feature to a smart watch like Apple Watch can provide a good solution for the solution.

Jung Hyup Kim, an assistant professor of industrial and manufacturing systems engineering at the school of engineering, has proposed a new function that will try to determine whether the driver is aware of safety problems and is actively taking protective measures, so as to guide the filtering of the ineffective alarm and make the alarm ring when it is really needed.

Kim's system uses pupil diameter change and electromyogram response ratio as two physiological indicators to predict the driver's imminent physical response to crash avoidance warnings.

The preliminary solution is to have a camera in the dashboard to monitor the eyes and look for changes that indicate that the driver is already in a tense state, as well as wrist-based sensors to track changes in muscle tension. The wrist-based sensor may be a smartwatch and can be integrated into an existing popular smartwatch.

Electromyography (EMG) is an electrodiagnostic medical technique used to evaluate and record the electrical activity produced by skeletal muscle. It has been widely used to classify human postures, quantify muscle strength levels by decoding user intentions and indicating patients'physical movements in health care. If Apple wishes, it can smoothly embed EMG sensors in future Apple Watch, and then introduce the latest version of watches into any car brand, such as Toyota or Ford, as part of ADAS.

In this way, the EMG data acquired by Apple Watch can be integrated into the vehicle assistant driving system, which can help to correctly judge whether the driver is in a muscle tense state, enough to respond to road conditions and vehicle conditions in a timely manner, and will effectively improve driving safety and reduce ineffective alarms.
