Essences of Interaction
defined to be that which operate in the context of forces.* Mechanisms have
various controls that govern the transformations of inputs into outputs.
Losses result from transforming input(s) into output(s). Outputs are measurable as performance(s). For reference: Figure 2.1 depicts the basic structure of
an object.
Arrowheads indicate the direction of “movement” of EMMI. The boundaries of the object correspond to physical, behavioral, and functional influences
on other objects. Boundaries are definable from either the object’s view or
that of another object. James Lake argued that “functional congruence must
exist between phenomena that underlie a specified symptom pattern and
phenomena operationalized as the mechanism of action . . .” (Lake 2007).
Objects and Mechanism
Mechanisms are the means by which objects and processes change. Change
means that an object or process is different at one instance from the previous
or next instance. Change is precipitated by EMMI. For objects, EMMI exerts
force(s) that influence(s) some or all the structures that comprise the object.
The structures (Reed 2008) (e.g., mechanical, electrical, and chemical) give way
to the influences of the forces derived from EMMI. Structures may give way to
these influences depending on their susceptibility to such influence. When
structures give way, they can have an impact on other structures influencing
these other structures depending on the coupling and cohesion between the
structures. Structures that give way in turn may influence other structures to
give way. The properties of structures (those intrinsic characteristics that have
resilience, i.e., relaxation and restoring action) have a semblance of reliability
if their variations due to some range of force and that force’s influence. For
some structures, their intrinsic properties reinforce the similarity in nature of
giving way based on like-kind influences on the structure(s). We refer to a
mechanism as beginning with that which EMMI influences and ending with
that which the mechanism produces as a result of that input EMMI.
Mechanisms respond to EMMI and transform EMMI into a different EMMI.
That transformation depends on the type of object and the circumstances and
environment that provide that object with a context for transforming EMMI. In
this way, mechanisms can be characterized by an enabling space, a transacting
space, and an outcome space (Trockel 1999). That objects have structures
* Force is defined as the influences of EMMI on objects. Were there no influence on an object,
there would be no force. That the influence should be measurable or detectable is of no consequence to this definition, as influence is relative. The test for influence is determined by the
net of power (i.e., work done) on an object as observed by the outputs of that object’s mechanism; changes in the object’s properties, traits, or attributes; or other such changes in boundary, boundary conditions, physical issues, and functional or behavioral issues (Kocsis 2008).
