Passive Haptic Exploration

There are two types of haptic interface with any environment, be it physical, or virtual. One is active haptic exploration, the other is passive haptic exploration. If we are to successfully reproduce these two types in VR, the differences are worth noting.

In passive haptic exploration, the user is not in control of their own actions. Another user or in VR, potentially a script guides their actions, and the haptic feedback is delivered in response to how their body parts move and what they touch. The advantage passive can have over active, is the system often knows in advance, where the next movement is going to be. There is therefore the danger that passive haptic exploration can be more stimulative than active haptic exploration, due to the extra processing power available.

You Tube of the first haptic, bionic arm versus a non-haptic
A comparison. Two women, both with prosthetic limbs. On the left, a standard prosthetic. On the right, a haptic prosthetic giving touch feedback. Who can complete the task faster, and is there much difference?

Book Quotes: Assessing Haptic Threshold
An interesting little quote from Mona Lisa Overdrive which provides brain fodder to chew on for the future of haptic (touch) interfaces.



One of the severe problems with haptic input devices (other than the very, very basic type that jack directly into the nervous system) is that the mechanics of hand-held systems only bend or push so far, then they hit engineered limits and the feeling dissipates.

Packbot to gain Haptic Feedback
In October 2009, iRobot announced that they would be receiving additional funding from the US Robotics Technology Consortium. They plan to use much of this money to add full haptic feedback technology to their heavy-duty robots.

Large Image Display: Animatrix: Final Flight of the Osiris: Facial Detail
This frame is from the widescreen version of ?Final Flight of the Osiris?, one of the Animatrix animated shorts. It has been considerably scaled back from the original material. Still, it exists to showcase the state of CG faces back in 2003. At least the CG possible when interactive VR techniques are applied to a passive VR production. In the years since this animation short came out, normal passive CG specialists have caught up. The question we ask here is, how come it took four years for them to catch up?
