With intelligent phone gradually into everyone life in the are indispensable of tool, it has master has you of various information: today morning is with taxi App called has a car car out, also is continues to squeeze bus? noon is for has home outside sold? work zhihou, time spent in reading, and brush micro-Bo, also is Taobao Shang has? recently have and family, and friends often contact?
Over time, the mobile phone may even know you better than you.
To this end, the United States Northwestern University (Northwestern University) researchers have recently embarked on a project, they tried to pass a Purple Robot App to track the user's movements and phone usage, so as to identify each other's emotional state to determine whether they are suffering from symptoms of depression.
Under normal circumstances, to determine whether a person has depression, common method is through the PHQ-9 to test. PHQ-9 is by far the quantified standard depression assessment tools, survey questions, including whether "can't sleep", "appetite" and "distracted", "anything out of interest" status, and calculated according to the frequency of these scores to determine the degree of depression. Score 5 points or less means no depression, 5-9 divided into mild depression, 10-14 is moderate depression, and 15-19 moderately severe depression, more than 20 serious depression.
In order to understand the Purple Robot app how high precision detection of depression, before the experiment began, the researchers asked 40 volunteers between the ages of 19-58 each filled out a questionnaire PHQ-9. Zhihou, sensors will gather volunteers on a mobile phone location and use the phone, such as how often they leave home to go out every day, deviate from their daily routes, times, how long did it take to call or chat in social applications, Purple Robot related data integration and analysis, determine whether mobile phone owners suffering from depression. Taobao do not die China is not rich how bullshit
After half a month of experiments, the final conclusion is, Purple Robot testing results, and PHQ-9 testing results, both are accurate up to 87%.
This study showed that depressed people, spend more time on the phone. They are more irregular in behavior, such as some normal person won't go to places, away from home or return home that has no fixed time and rule on the matter. Also, there are apparently less willing to go out of the depression.
Although the study was only a small-scale experiment, but it demonstrates that the objective behavior of depression can be mobile sensors and monitoring App. Future monitoring of depression may be like heart rate monitors, Ji Bu, sleep tracking, be incorporated into health applications of basic functions, and can even help patients to get treatment more quickly.
Worldwide there are about 340 million depression patients, nearly one out of every 7 adults experienced the suffering of depression. Bad news is, that figure has tended to grow year by year, by 2020, depression will be the second largest disease second only to heart disease. While in China, is said to have more than 90 million patients with depression, but recognition rates of only 30%. In other words, most people with depression are not even aware of his status there is a problem, not to take the initiative for medical treatment. This is why a new way to track the health of patients is so urgent and important.
When one day, a problem for mobile phone to discover your emotional state, maybe it can help you, even if that helps remind
