防止情侣夫妻吵架 研究人员研发冲突预测系统

近日,南加利福尼亚大学进行了一项新研究,旨在研究可穿戴设备是否可以预测夫妻情侣之间的冲突。通过利用机器学习技术,研究人员建立起了一个可以准确捕获冲突事件的系统,据称准确率高达 86%。同时,研究人员希望能继续研发机器学习算法,未来的改进版将有望在冲突发生前 5 分钟就能发现冲突即将到来时的生理体征,以此来预测冲突的发生,最终起到预防冲突发生的作用。这种功能可作为一个独立的软件集成至市场上有售的可穿戴设备上使用。

研究人员表示,大部分研究是在实验室外进行的。参加实验的夫妻情侣获得了研究人员发放的佩戴式传感器和智能手机,两人被要求每小时完成一次录音,记录下他们对一些重要事件的想法和感受。

可穿戴设备将追踪参与者的体温、心脏活动和汗分泌水平。然后将这些数据与录音进行交叉参考,并对其进行了分析,以此获得对内容和语音强度的观察,从而使计算机能够确定这些事件过程中是否有冲突出现。

WEARABLE DEVICE CAN ANTICIPATE CONFLICT BETWEEN SPOUSES BEFORE IT HAPPENS

WHY IT MATTERS TO YOU

Wearables have become typecast as fitness trackers, but projects like this one show that they could have an impact on many aspects of our health and well-being.

The University of Southern California has published the results of a new study that sought to find out whether wearable devices could anticipate conflict between couples before they occur. Using machine learning techniques, the researchers were able to establish a system that could apparently capture conflict episodes with an accuracy rate of up to 86 percent.

The majority of the research was conducted outside of the lab, according to a report from TechCrunch. Couples were given wearable sensors and smartphones to record data, and asked to complete a survey every hour recording their thoughts and feelings regarding their significant other.

The wearable devices kept track of the subjects’ body temperature, heart activity, and sweat levels. This data was then cross-referenced with audio recordings, which were analyzed to gain insight into the content and intensity of speech so that the team could determine whether or not conflict had emerged.

The researchers hope to continue to develop their machine learning algorithm, in the hopes that an improved version could spot the physiological signs of conflict up to five minutes ahead of time. This functionality could potentially be made available on commercially available wearables as a stand-alone piece of software.

At present, keeping fit remains the most common reason for people to don a wearable device, both in terms of dedicated fitness trackers like the Fitbit, and more general-purpose devices like the Apple Watch. However, various different research projects are demonstrating that this kind of technology could be used to provide all kinds of different health benefits.

In December 2016, a wearable that can counteract tremor caused by Parkinson’s disease was showcased on the BBC television program The Big Life Fix. Earlier this month, a campaign to fund a wearable that can apparently provide relief from menstrual pain launched on Indiegogo.

People weren’t as quick to jump on the smartwatch bandwagon as many manufacturers anticipated that they would be. However, wearables that provide tailored health services may prove more popular, if they can offer tangible improvements to their users’ quality of life.
