How The Illusion Becomes Real In Virtual Reality
As a user looks into a make believe setting, their senses and the systems response mechanism should always be in harmony. For example, sound denoting a car just crashed in the virtual environment should be persuasive. This increases the level of engagement and concentration.
A baby tries to walk way before he can talk. Humans are created for motion. A system that negates this innate desire, does not quite cut it. There needs to be a direct correlation between the reality and the make believe environment. Imagine someone throwing cold water on you and the response to the chilling experience never came or was late?
The discrepancy that exists between a user’s action and the corresponding system’s response to that action is called latency. For example as you are moving around looking for a robber in a virtual setting, how long does it take the unit to notice that you tilted your head left or right? Given the million or so years the human brain has evolved, it is keen to note that you can easily notice such a delay in about 50 milliseconds. This pause in time causes your concentration to divert and as a result, you are back to reality.
Virtual reality crumbles on that simple hesitation. A good designer therefore should be so good at creating a replica, that you fail to notice everything around you including the computer. You become another version of yourself. Judging from the look of things, developers have a clear roadmap. The approach keeps getting more and more human. Eventually, you will be able to completely lose yourself in these make believe environments.
