Detection of Perceived Mental Stress Through Smartphone Photoplethysmography


In the previous step, we have tried website tools to help users to self-detect their stress levels. Here is another research on how to utilize the capability of mobile to detect mental stress.

Instant Stress: Detection of Perceived Mental Stress Through Smartphone Photoplethysmography and Thermal Imaging

In this paper, the research team builds a mobile monitoring system with a smartphone camera-based photoplethysmography (PPG). Combining PPG and thermography, the team aims for the cardiovascular signal to detect any stress responses. During the experiment, they have found meaningful PPG signals presented high-quality cardiac cyclic information. The results demonstrate the feasibility of using smartphone-based imaging for instant stress detection. Given that this approach does not need long-term measurements requiring attention, this research presents a new possibility for mobile mental health care solutions.

How would you think if your smartphone can detect stress level? Do you agree to such development? Why or Why Not?
