Virtual reality is being used in education, training, business, entertainment (Stair & Reynolds, 2014). It also has uses in the medical field. Since virtual reality immerses the user in a simulated environment, it is being used to treat patients diagnosed with post-traumatic stress disorder (PSTD). It is called virtual reality exposure therapy (VRET). The patients are able to confront feared situations or locations in the safety of the doctor’s office. Studies have shown patients experiencing a reduction in PTSD symptoms following VRET treatments (

Virtual reality is an artificial environment, which is created using software and presented to the user in a simulated environment in such a way that the user suspends belief and accepts it as a real environment. On a computer, virtual reality is primarily experienced through two of the five senses: sight and sound. Virtual environments are used in training programs for the military, the space program, and even medical students. The military have long been supporters of VR technology and development. Training programs can include everything from vehicle simulations to squad combat. Overall, Virtual environments systems are much safer and, in the long run, less expensive than alternative training methods. Soldiers who have gone through extensive Virtual environments training have proven to be as effective as those who trained under traditional conditions. One of the systems in the military that is largely used is the Engagement Skills Trainer. This specific system provides realistic marksmanship and combat scenario training for a large number of the most common small arms, crew -served weapons and individual anti-tank weapons in the Army’s inventory.

RFID is “a technology that employs a microchip with an antenna to broadcast its unique identifier and location to receivers” (Stair and Reynolds, 2014). RFID tags are great for keeping track of merchandise or inventory. RFID tags can increase productivity because multiple items can be scanned at once. In my community’s library there are RFID tags in the books. Checkout takes very quick because all you need to do is place the whole stack of books on the reader and they are all scanned. No more moving the barcode around until you get it in a good position. Other advantages of RFID over barcodes are that they can be read from greater distances, they are more secure, and once set up, they can be used with minimal human participation (Logistics & Materials Handling Blog, 2012).

However, the cost of implementing RFID technology is a big concern. There are many costs associated with this technology. There are the tags, readers, frequencies that have varying costs. As with any new technology, the startup cost is large, but can be worthwhile down the line. This cost has to be analyzed by each company to determine if RFID is worth it for that company.

The US Army started the implementation of RFID technology and usage in 2003 on a large scale as the US entered the Iraq war. An army ca not be moved wit out operational logistics soldiers don't move without food guns are ineffective without ammunition, vehicles don't run without fuel and repair parts are critical in order to win the war. Thousands of 20 foot containers left home stations bound for container containment areas in Kuwait with a hope and a prayer that the RFID system implemented would produce the results that the military needed.

With the system in place if helicopter engines were needed the logistics warehouse had the ability to search the yard for the exact tag pinpoint it and process the container for critical movement to the front. There was the ability to move the important stuff first and keep the fighters fighting.

In addition to being able to now track parts from both the supplier to the individual customer as well as home station shipments the RFID tag is completely loaded with a manifest of parts request numbers and quantities that can be scanned and processed. This additional ability to be able process a full container with the scan of a card reader allows the warehouse to close he receipt for shipment and allow the supplier to be paid simutaniously affecting the inventory counts on hand and cutting receipts to the intended customer in the course of under 60 seconds something that 20 years ago could have taken a staff of 30 2 days to make happen.
