Wearable technology
The creation of the first virtual reality headset can be credited to Cinematographer Morton Heilig. He created a device known as the Sensorama in 1962. The Sensorama was a videogame like device that was so heavy that it needed to be held up by a suspension device.
Virtual reality headset
The virtual reality headset allows the military personnel to interact with virtual reality people to make it feel real. They can talk to one another and do varying actions to make the virtual reality world feel like they are actually in that situation. There are also disadvantages and advantages when military personnel use the headset. The disadvantage is the headset is made for an indoor area, with a cool environment, and away from any heat, so when military personnel have just the headset on, no military equipment, it is not like their basic training. The advantages consist of repeating the situations multiple times and the cost of having the headset is less, due to no military equipment being needed.
