Ann- Medicine:

The virtual reality headset helps with therapy. People with mental health issues and addictions use therapy by virtual reality headsets to help get over these issues. The Virtual Reality Headset helped patients get over fear, anxiety, panic, and acrophobia. One patient got over anxiety about spiders through a virtual reality headset. The patient was exposed to a virtual spider for 50 minutes for 12 weeks. The Virtual Reality Headset also was used for exercising. Many exercising programs and sports games were created. When a patient is going through therapy, the patient has control over the exposure they have. During the exposure, the patient’s thoughts, feelings, muscle tension, and heart rate are all observed. Virtual Reality has psychological principles from cognitive-behavioral therapies, neurobiology, neurophysiology, existentialism, and psychodynamic conceptualizations and knowledge in behavioral neuroscience. The Virtual Reality Headset helped patients get some emotion relief from their day-to-day medications.

Zaondra- Military:

The virtual reality headset allows the military to interact in more complex situations. The situations they are put in allows them to train for real-life events and to be ready for those types of events in the future.

The virtual reality headset allows the military personnel to interact with virtual reality people to make it feel real. They can talk to one other, do varying actions, making the virtual reality world feel like they are actually in that situation.

There are disadvantages and advantages when military personnel use the headset. The disadvantage is that the headset is made for an indoor area, with a cool environment, and away from any heat, so when military personnel have the headset on inside with no equipment, it is not like their basic training. The advantages consist of repeating the situations multiple times, no injuries or illnesses will ever occur when training with the headset on, and the cost of having the headset is less because no military equipment is needed.

Constraints:

Visual Resolution:

There are different optics and visual qualities that will affect how the individual visuals the image quality and how they experience the virtual world. The image will appear clearly due to the display resolution, optic quality, refresh rate, and the field of view.

The current virtual reality headset has 10 pixels per degree. The screen is so wide and large, giving a wide view. A human has a resolution of 70 pixels per degree. The average pixels per degree will ultimately affect the individual that is wearing the headset, causing them to see pixels.

Lens:

Lenses are important to the headset; it is the key factor in making the virtual reality world have a clear, quality image. Many manufacturing companies have used a variety of lenses, but many have used the "Fresnel" lenses. The lenses do not use multiple pieces of material in their lenses like other lenses, but the lens will be broken down into sections, allowing the individual to have a wider range of view. The issue with the lens consists of seeing the ridges of the lenses when the headset is not properly aligned on the head.

David- New subtitle under constraints:

Virtual Reality was used by Nintendo's Wii game console by having the player use a controller to interact with the game of their choice, often being sports games. Soon after the release of Nintendo's Wii, Xbox released a full body reading system called "Kinect" and PlayStation released a similar virtual reality device named "PlayStation Move." These gaming devices use virtual reality to control avatars within a game, where the player's movements are copied by the avatar to complete the game. This means that the player is not truly engaged in the virtual reality world.[1]
