PRODUCT DEVELOPMENT FEATURE
sidering the driver-operator, assembly
worker or service technician, experience-based
human-centric validation
of the product within an intended process
and performed early in the product-development
timeline greatly improves
the overall product and assures
sustainable operations.

VR validation of operator interactions
in and around proposed products accelerates
product-development timelines
by effectively enabling engineers and
other stakeholders to perform humanfactors
studies on 100% digital inputs.
People can sit in a virtual cockpit or driver's
seat of a future product, and ergonomists
could then cycle a wide range of
individuals through cockpit validations
for driver reach, view and comfort. All of
this is achievable without a physical testing
environment.
Recording and measuring interactions
between all the different possibilities of
operators and engineering design variants
is another seemingly insurmountable
task. To address this challenge, recording
the movements of people and
virtual objects and playing back those
interactions is possible, but with digital
human models representing a wider
range of anthropometries than one may
have available to them. With this capability,
it is possible to combine the very
fast first-person experience for reach,
view and comfort with third-person analytics
across a diverse population and
complete range of design variants.
Enabling engineers and stakeholder
teams to experience operator processes
within the proposed products virtually
can reduce latent risk to operator
safety and user comfort. Whether conTRUCK
