Haptic
devices provide force feedback to humans interacting with virtual
or remote environments. Such devices convey a kinesthetic sense
of presence to the operator. The key characteristic that distinguishes
a haptic interface from passive devices is a bi-directional flow
of information.
Linear
Haptic Display (LHD)
- A 3 degree-of-freedom haptic device, built for maximum workspace,
force output, and structural stiffness. It features a patented
steel cable transmission system which enables high forces and
high rigidity in the three orthogonal axis of translation motion.

Status: Active use |
Fingertip
Haptic Display (FHD)
- A 2 degree-of-freedom haptic device whose mechanical design
is optimized for the workspace of the human finger. This device
is being used to study human perception of curved surfaces and
surface discontinuities.

Status: Active use |
Pen
Based Force Display (PBFD) - A
direct-drive, parallel, actuation redundant, three degree-of-freedom
haptic device designed to provide force feedback information
generated by either a master-slave system or a virtual simulation.
The operator interacts with it using either the fingertip or
a freely held pen-like tool.

Status: Active use |
High
Bandwidth Force Display (HBFD)
- A two degree-of-freedom force display for the study of simulated
interactions with heavy and stiff virtual objects involving
whole-arm motions in the plane. It consists of a kinematically
simple cartesian mechanism driven by brushless DC motors through
a steel cable transmission.
