Millisecond: one thousandth of a second.
Nanosecond: one billionth of a second.
The smallest viable measurement of time is derived from a unit of distance called the "Planck" length where dimensions are so tiny that the classical laws of physics break down and quantum effects kick in.
A Planck time is the time light takes to travel one Planck length. This is currently the smallest time measurement that will ever be possible. What is the smallest unit of time you can conceive? A second? A millisecond? Hard to say seeing as how time is relative. Under the right circumstances, hours can fly by and seconds can feel like a lifetime.
Realtime? Human perceptions or how fast can the human mind process sensory input? First, some background.
- Response time at 100ms is perceived as instantaneous.
- Response times of one second or less are fast enough for users to feel they are interacting freely with information.
Normally as to perception to action it is believed that on average human responses of 2-seconds is ideal.
“As humans beings, we have the curious inborn ability to observe and experience the persistent passage of time. The architecture of our human brains however, limits our sensory perception in a way that prevents us from reacting to our perceptions within a certain short timeframe. This timeframe is commonly known as Reaction Time.”
Speaking of averages, humans on average have a reaction time of 250 milliseconds or a quarter of a second. This varies to each person as some react faster and some a bit slower. Folks like fighter pilots, and many violence professionals, fall into the 100 - 120ms reaction-time.
How does this work, in general? Remember that such things are complex and involve certain mental processes, i.e., the actual sensory perceptions and we can look at this as the orientation process, then we have to receive that input into our consciousness and often that depends on the input and how we have that data stored from study and experiences, then the brain must apply context to that input and in our discipline that context must include intent and we can look at that as the decision process, and finally a decision must be made based on what output is required and that is our action process.
The goals of training, practice and experiences along with the more academic aspects that must be balanced with the physical means to achieve the greatest speed, or speed faster than our adversary, we must focus on sensory perceptions. We can call this our awareness.
Our sensory systems must shake out relevant one’s over irrelevant things whether visual, auditory or tactile or any combination thereof.
Some trivia, humans in general can interpret visual queues seen for as little as 13ms (that is about 1 in 75 frames per second).
So, through our training and practice process along with study we must understand that our brain receives incoming sensory data as an asynchronous process that acknowledges that input, assuming you have some data or memory or other belief already in the brain, and that it is admitted into our consciousness. Once awareness in the mind is achieved then another part of our brain is triggered.
That part of the brain relies on what is stored from the past will assign both context with intent to that data so that the other processes described can be made on how we act/react. All of this happens very fast assuming all things are in place such as training, practices, experiences and a data-base chocked full or relevant data.
There are limitations to human ability so understand.
- Processing of stimulus seems to be maxed out at about 13ms.
- Increasing negative impact on that number degrades human performance for that given task giving credence to the tool whereby one overwhelms the others brain functions like putting them into a OO bounce where orientation cannot be achieved because there is no reference stored in our brains.
Everything in nature has limitations and one must know, understand and pay attention to those limitations when training, practicing and understanding what it is we wish to accomplish in self-protection for self-defense through martial disciplines like karate.
This type of data is how we strategize our tactic, multiple methodologies, to overwhelm an adversary so that we can maximize our perceptions to orientations to decisions to actions because all things being equal it is the only way to gain the upper hand to protect, defend and secure against conflicts and violences.
As you have already visualized reading this article we can achieve successes if we maximize what we know, what we think we know and what we don’t yet know we know and don’t know to build our data-base so when we train, practice and apply skills we beat the adversary in processing our OODA.
