Steady-State Visually Evoked Potential
The steady-state visually evoked potential or SSVEP, is an event related potential generated by the human brain, when visual stimulus applied to the retina in the form of changing patterns or lights frequency causes the brain to synchronize. Wen this happens, that pattern shows up in the brain waves and can be detected by non-invasive neuroprosthetics.

In a previous article, Are prosthetics Obsolete? Priced out of The Heal Game, we took a look at the state of the prosthetics industry, which is in a state of disrepair due to costs. This article examines one possible solution to the spiraling cost of prosthetics, already being implemented.
Emotion is a tricky beast. We still do not fully understand what triggers a given emotion, in terms of the neurochemical signals in the brain, despite several years of study. This is because of the difficulty of determining whether an electrical pattern is triggering an emotional state, or is caused in response to an emotional state.
Ongoing research into potential piezoelectric power sources for smart prosthetics turned up a powerful - and deadly - candidate in a polymer that is already used for many cosmetic implants. silicon polymer is a fantastic source of energy when squeezed. However, it also damages the organic cells around it each time this occurs.
Race is the enduring, heartbreaking problem of modern, multinational society. No matter the country, no matter the society, if there are people who are visually or culturally different from other people, the race card flares. VR cannot of course sweep all of that away overnight. It can however offer another way, after all, race is all about the physical, and VR is very good at making the physical, not matter.
ActiveWorlds Gate 5.0 launched on November the 26th 2009, in readiness for the launch of ActiveWorlds 5.0 on December the 1st 2009. Here we see one of the rooms off of the main concourse, where the company nods politely to all the independent radio firms that operate within it's platform. Eight platforms are available. To hear the music, just stand in the column-shaped invisible zone on top of each disk, and the music will start streaming, assuming the radio station lives long enough of course. This location brings home another problem the platform is trying to hide - the steady decline of users.
