     Feeling is Believing: Haptic Exploration of Virtual
Objects

How 'real' objects can be conveyed in a virtual environment?
One's mind
has to constantly integrates the visual, auditory, tactile
cues to gain an
understanding of the environment one perceives to be in. 
The 'reality' of
virtual objects is completely based an individual's
perception and
interpretation of surrounding cues.

I will present a study conducted at Sheffield DCS that
investigates an
individual's perception of objects in a virtual environment
through touch
alone, with the use of an haptic device: PHANToM. It will
also question
whether size can be accurately determined and whether the
stiffness of the
object affects their judgment.

Texture is an important factor to give the presence of being
real.  The
study also concentrated in discovering what an individual is
feeling on
given set of parameters and whether texture information is
useful about
features of the an object such as form, texture, friction
and hardness.

What is 'real' is left to the person's imagination and
previous
experience. This experiment has questioned what is inside
one's thoughts,
to try to derive how people operate and put in action their
thoughts in a
virtual environment.
