Galvanic Skin Response
Galvanic skin response or GSR, is a type of limited sensory output that can be used to help detect changes in a participant?s emotional state, as an interface method for a virtual environment. The galvanic skin response is essentially a change in the electrical resistance of the person?s skin that occurs a few milliseconds after the person has experienced an emotional state change, mentally. Currently, no method exists to determine which emotional state is now in charge.

Researchers have prototyped an electrotactile second skin to be worn over the first, which adds additional pressure sensation to the user's own sensory capabilities – it makes the natural skin much more sensitive to touch.
Second Skin was a 2007 documentary about virtual worlds and their impact on people's lives. It is a documentary that could not be more polarising if it tried, and there is plenty of evidence to suggest they did exactly that.
A look at a new means of low-cost, high effectiveness under-skin imager, designed for use in the doctor's office and in the field, that offers a low-cost, high-precision alternative to CT.
Wouldn't it be marvellous if artificial pressure sensors could bend and flex like their organic counterparts? If synthetic skin could knead and twist like normal skin, but remain just as keen of sense? We are not there yet, but the first prototypes that can behave naturally under strain, are already here.
German researchers have created an inexpensive to manufacture, tiny biosensor not much larger than a splinter. It is designed to pierce the skin and sit under the outer layers, monitoring swet and tears for glucose levels, and reporting back its findings, continuously.
Galvanic Vestibular Stimulation. For those of us familiar with it, it's a possible panacea to cure simulation sickness, and rope the sense of balance of the user directly into the simulation. Unfortunately, it seems there is a fly in the mixture.
Industry news from August 2005, featuring the debut of 'galvanic vestibular stimulation' or GVS. GVS is a means of controlling the input sent to the body's balance centres via a pair of devices behind the ears. Capable of tilting your balance to make you think you are moving in any direction at any time, GVS offers many hopes for cheap, mass-market movement simulation.
A potent look at closed captioning systems in VR and in gameworlds, including the staggering capabilities possible, the incredible customer response when it does occur, and asks why more developers aren't considering sensory substitution in designing their worlds?
