- i have been reading the control systems group (CSG-L@uiucvmd.BITNET) for
- some years now, and i find their discussions far from convincing.
- ocassionally some bit of insight, enough to tantalize but not enough for
- thorough work. like the behaviorists before them, elemental linguistics
- eludes them.
-
- good, give us some examples of how concepts can be taught through sensory
- data, no matter how complex. i did admit to the benefit of VR in sensory
- translation when the relevant phenomena is otherwise imperceptible. but
- these are, by and large, exotic topic areas. if there is really a need for
- basic perceptual training in some area, there are usually enough of the real
- objects around for realtime manipulation. if the objects are not readily
- available, how is the need for the training so significant? the effort to
- establish virtual environments will be cost effective only in uncommon
- cases.
-
- in semantics we have what is called a denotational definiton, often used
- for the simplest concrete concepts. you define a concept by giving a series
- of examples, allowing the user to generalize the definition. dictionaries
- need to supply little pictures of these basic types. i admit that a VR
- dictionary would be neat, being able to reach in to feel, hear and taste the
- objects thus defined. but even in the middle ages, they recognized that
- connotative meanings escape denotive definition. that is why they are always
- marked on the side, defined with symbolic structures (usually linguistic,
- sometimes mathematic).
-
- what sensory data would you use to define 'truth'? it is a kids joke
- the when the dictionary defines 'ugly' they put in a picture of you. :-)
- one of the earliest concepts acquired in child language is the genitive.
- no amount of sense data defines the concept of possession, yet it appears
- fairly commonly in verbrete and some arthopoid life forms. symbolic
- manipulation is our best method of representing those meanings which do
- not have definition by example. virtual realities are not going to aid
- much in those areas, and most of education (beyond the elementary) is
- concerned with such.

- >>
-
- yes, consider expert knowledge. it is valued because it does not resemble
- common sense. again we are talking about exotic, peripheral areas of
- curriculum. that will be the forte of VR, the heart will remain in symbolic
- textual structures for considerable time to come.
