Six/Seven DOF Haptic
A Two DOF Planar Haptic Interface:
We have designed a desktop haptic interface (a programmable force feedback
mouse so-to-speak). Several prototypes have been constructed to date. Prominent
features of this device include a large workspace, low friction, low inertia,
high rigidity and a minimal intrusion in the work area. Programmed mechanical
models are used to kinesthetically describe the features of an interface.
These models are analogous to iconic representations in conventional graphic
interfaces. Users, acting and perceiving through the haptic channel, simultaneously
perceive simulated objects through the visual and auditory channels (Fig.
6.5). Although this design is now five years
old, it still supports a number of experiments.

Many versions have been produced and experimented with. Presently, Haptic
Technologies Inc., Montréal is marketing one version equiped with
an embedded processor. A newer product has evolved from the original design
named the PenCat/Pro. (Figures 6.6 and 6.7).
