Controller mapping allows users to manually sidestep control issues -- something select games suffered from on the Wii VC when paired with a Gamecube controller.
Using new genetic techniques such as molecular mapping, they have located a set of genes on one chromosome that appears to control the process in a grass species called Tripsacum.
But now, NeuroSky (a fab(u)less startup of US chip designers and Russian neuroscientists chillin' in NorCal) claims a "breakthrough" in non-invasive neural sensors allowing low-cost, dry (no contact gels) neural mapping solutions to be applied to those things you'd most like to mind control (spouse, voters, TV, game console, cellphone).
