Although mobile devices, cellular phones, Personal Digital Assistants (PDAs) and other
handheld devices have hardware constraints such as small screen, small storage, low CPU
speed, and low resolution, their popularity has been enormously increasing. This is
enhancing the opportunities for researchers to overcome those open problems caused of
small size hardware constraints. However, still the biggest difficulty is that these devices are
too difficult to load today’s visual information because most current information is based on
a large visual documentation.
Technological advancement in graphics and other human motion tracking hardware has promoted pushing "virtual reality" closer to "reality" and thus usage of virtual reality has been extended to various fields. The most typical fields for the application of virtual reality are medicine and engineering.
Many advanced systems were developed for forklift
applications such as rear combination lights for
improved protection and reliability, traction & brake
control (TBC), system of active stability™ (SAS). In
1999, The Toyota SAS was first introduced on the
7-series. It is an electronic controlled system, which
automatically observe and controls over 3000 key
forklift functions, which senses instability and then
instantly engages the swing lock cylinder to help reduce the risk of lateral tip-overs...
Most haptic devices are intended primarily, if not exclusively, to exchange information with
a human operator, and often replace or augment traditional computer displays with
backdrivable, force-producing tactile interfaces. This includes popular commercial devices
such as the PHANTOM (Massie & Salisbury, 1994) that are typically limited to at most
several Newtons of endpoint force capacity, just enough to display simple virtual
environments to the operator.
