HAPTICS
ACUPUNCTURE
Acupuncture is the science and art
of human haptics - the ability to manipulate and activate haptic nervous
system....by needle stimulation
Haptics refers to sensing and manipulation through touch. Since the early part
of twentieth century, the term haptics has been used by psychologists for
studies on the active touch of real objects by humans. In the late
nineteen-eighties, when Scientists started working on novel machines pertaining
to touch, it became apparent that a new discipline was emerging that needed a
name. Rather than concocting a new term, we chose to redefine haptics by enlarging
its scope to include machine touch and human-machine touch interactions. Our working
definition of haptics includes all aspects of information acquisition and
object manipulation through touch by
humans, machines, or a combination of the two; and the environments can be
real, virtual or teleoperated. This is the sense in which substantial research
and development in haptics is being pursued around the world today...
It may be possible to design a Haptics AcuRobot that can be programmed to do
precisely the exact same things that a David or Kiiko can do? ....and a Haptix
Nanobot that can get inside and do what we can do.
WoW - The future is interesting!
Some more if you are interested in this line of thinking -
It will be difficult - very very difficult & complex...
When a human user touches a real object directly or through a tool, forces are
imposed on the user’s skin. The associated sensory information, mediated by
sensors in the skin, joints, tendons and muscles, is conveyed to the brain by
the nervous system and leads to haptic perception. The subsequent motor
commands issued by the brain activate the muscles and result in, say, hand and
arm motion that modifies the touch sensory information. This sensorimotor loop
continues to occur during both exploration and manipulation of objects.
In order to create the sensation of touching virtual objects, we need to
generate the reaction force of objects applied on the skin. Touching a real
object through a tool is mimicked by the use of a force reflecting haptic
interface device. When the human user manipulates the end-effector of the
haptic interface device, the position sensors on the device convey its tip position
to the computer. The models of objects in the computer calculate in real-time
the torque commands to the actuators on the haptic interface, so that
appropriate reaction forces are applied on the user, leading to haptic
perception of virtual objects.
In order to develop haptic interfaces that are designed for optimal
interactions with the human user, it is necessary to understand the roles
played by the mechanical, sensory, motor and cognitive subsystems of the human
haptic system. The mechanical structure of the human hand consists of an
intricate arrangement of 19 bones connected by almost as many frictionless
joints, and covered by soft tissues and skin. The bones are attached to approximately
40 intrinsic and extrinsic muscles through numerous tendons which serve to activate
22 degrees of freedom of the hand. The sensory system includes large numbers of
various classes of receptors and nerve endings in the skin, joints, tendons,
and muscles.
Appropriate mechanical, thermal or chemical stimuli activate these receptors,
causing them to transmit electrical impulses via the afferent neural network to
the central nervous system (of which the brain forms a part), which in turn
sends commands through the efferent neurons to the muscles for desired motor
action.
In any task involving physical contact with an object, be it for exploration or
manipulation, the surface and volumetric physical properties of the skin and
subcutaneous tissues play important roles in its successful performance. For
example, the fingerpad, which is used by primates in almost all precision
tasks, consists of ridged skin (about 1 mm thick) that encloses soft tissues
composed of mostly fat in a semi-liquid state. As a block of material, the
fingerpad exhibits complex mechanical behaviour -- inhomogeneity, anisotropy,
rate and time-dependence. The compliance and frictional properties of the skin
together with
the sensory and motor capabilities of the hand enable gliding over a surface to
be explored without losing contact, as well as stably grasping smooth objects
to be manipulated. The mechanical loading on the skin, the transmission of the
mechanical signals through the skin, and their transduction by the cutaneous
mechanoreceptors are all strongly dependent on the mechanical properties of the
skin and subcutaneous tissues.
Extending
the Haptics & Computer train of thoughts to Acupuncture:
I believe acupuncture works rather like pushing the keys of Keyboard/
Mouse-click/ Touch ( Haptics) on a Electronic computer. ( a simple action but -
an expert programmer can write a very complex code elegantly using very few key
strokes/ lines of code )
1. If we agree that our unconscious mind regulates the body functions then and
our thought can affect the outcome positively or negatively.
2. If we adopt the concept that the body/mind is a bio-computer, which contains
a fiole of somatotopic network of information about the state of the body, and
is accessed both by thought and emotional energy, then by stimulating the
acupuncture points by touch, needles, EA, LASER can have profound effects. (No
need to worry about database - it is already there - Brain-memory-Storage
hard-disk & DB !)
3. It is a virtual bio molecular-world- a holographic world, inside the
bio-computer. Certain combination of acu-points stimulated instruct a response
from the unconscious mind,CNS/ HPA BrainNet which works by changing not just
the chemical messengers released, but also the autonomic impulses and several
sub-systems - Musculo-Skelatal, Fascial, Neural, Chemical, Digestive, Thermal,
Cardio Respiratory systems - all sub-systems in the BrainNet....The extent of
changes depends on the usefulness of the stimulation? and already existing
Brain Rules?
4. Brain Rules may be simple or complex depending on what we try to activate.
It may have a encrypt and decrypt code that can be unlocked only by certain
combination of stimulation keys ( AcuPoints)? This may be different from DNA
Code ( which is probably hard-coded) - what we are talking about is Brain
Operating system and application software that can be changed/customized for
different sub-systems and their hardware ( Muscles, Heart, Lungs, Liver etc) to
run the bio-computer.
5. This model makes some sense ....may be - but most of the research seems to
be aimed at proving the effects rather than the mechanism of delivery. The
Delivery side of Acupuncture needs
more models, approaches, Research etc - may be
The reason I am worried about Delivery of Acupuncture is very simple. If it
took 2500 years to invent and perfect Acupuncture - we should not spend the
next 2500 years in trying to find How Acupuncture Works! With such low side
effects - we should say - Lets do it WITH TECHNOLOGY.
