Researchers from the Northwestern University in Chicago are developing a number of web-based applications, including a smartphone and a medicine bottle, in order to help people overcome depression and other mood disorders.
The smartphone makes use of a technology known as Mobilyze! and identifies symptoms of depression by tracking a person's activity patterns such as the number of phone calls and messages. If the phone feels that you have deviated from the usual pattern, then it sends in a messaging suggesting you to call your friends.
Another device which the researchers hope will be helpful is a medicine bottle that reminds the patients to take their pills. The bottle is connected to a mobile app that collects information regarding symptoms and medication side effects and then sends the information to a doctor to determine whether any change is needed in the dose or the drug.
