Haptic Bladder

A haptic bladder is one of the most primitive, albeit effective haptic interfaces. Essentially it is a tiny air-filled sac made of a stretchable but durable material. Linked to an air pressure system via tiny pipework, such bladders coat the inside surfaces of haptic devices worn against the skin.

As the user's skin rubs up against the space where a virtual object is supposed to be, the bladders inflate, applying pressure to the skin at that location and simulating the physical feel of an object.

The larger the number of bladders, the more accurate the feeling.

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.

Haptics via Ultrasound
All manner of approaches are being fielded these days to try and create a workable haptic interface, that allows the true feeling of touch to an object that is only virtually there. One of the more esoteric, is the use of sound to shape the pressure fields in the air. Specifically, the use of ultrasound.
