Anxiety disorders are, by far, the most common psychological disorder.

Anxiety is a natural human reaction that involves mind and body. It serves an important basic survival function: Anxiety is an alarm system that is activated whenever a person perceives danger or threat. When the body and mind react to danger or threat, a person feels physical sensations of anxiety — things like a faster heartbeat and breathing, tense muscles, sweaty palms, a queasy stomach, and trembling hands or legs. These sensations are part of the body's fight-flight response. They are caused by a rush of adrenaline and other chemicals that prepare the body to make a quick getaway from danger. They can be mild or extreme. There are 6 major types of anxiety and research has determined that 15-19% of individuals have experienced clinical levels in at least one anxiety category.

These types include Generalized Anxiety Disorder (characterized by six months of excessive worry/anxiety, muscle tension, sleep problems, fatigue, and autonomic restrictors such as image avoidance), Social Anxiety Disorder (the most common form with about 13/3% of the population experiencing symptoms at some point. It is marked fear of social/performance situations, such as going to crowded places, peeing in public, etc), Panic Disorder (a condition in which individuals experience multiple uncued or (the attack is uncontrolled by the patient and often unknown when they may have one ) panic attacks and worry about these attacks for over one month), Type I Obsessive Compulsive Disorder (characterized by obsessions that cause anxiety and compulsions used to alleviate it), specific phobias, and post-traumatic stress disorder.

In line with this, your requirement is to create your OWN device or application that you believe can relieve the feeling of anxiety of an individual.

Follow the UCSD model in developing the device. Focus on the four major steps, namely:...
