Digital Diagnosis: Your Smartphone Says a Lot about You

Times of India reports that the more time you spend on your mobile phone, the more likely you are suffering from depression, says a study. According to researchers, depression can be detected from your smartphone sensor data by tracking the number of minutes you use the phone and your daily geographical locations. The team from Northwestern University found that the average daily usage for depressed individuals was about 68 minutes.

For non-depressed individuals, it was about 17 minutes. Spending most of your time at home and most of your time in fewer locations was also linked to depression. Also, having a less regular day-to-day schedule, leaving your house and going to work at different times each day, for example, is also linked to depression. "With phone sensor and GPS data, we can detect if a person has depressive symptoms and the severity of those symptoms without asking them any questions," said senior study author David Mohr from Northwestern University's Feinberg School of Medicine. Phones can provide data unobtrusively and with no effort on the part of the user.

With facial recognition software developing fast and news that Facebook's Oculus is going to buy gesture-recognition firm Pebbles Interfaces, our  mobile phones can tell a lot about us. This information would be very useful for employers and insurers.
