'Just Think It' to 'Design It'

How many science fiction movies have featured elements of ‘mind-control?’ Recall the squid-like alien monster that taps into the mind of the President of the United States in the epic ‘Independence Day!’ Well, alien or not, we are about to join our telekinetic space invader foes.
Artificial Telekinetic (AT) technologies are now rolling out of the lab, and being applied in high-end applications such a remote mind control of military assort vehicles and flying robot drones; mechanized hospital beds, wheelchairs, voice box simulators; videogames, and here, Computer Aided Design (CAD) Interfaces.
Pioneering CAD interface technologies are enabling designers to select and control on-screen 3D graphic solid-models using the power of the mind! Woo!! Integration of thought controlled headwear means designers can use AT to design whole models and schematics with brain waves alone.
Emotiv ‘EPOC,’ founded in Sydney in 2003 by technology entrepreneurs Tan Le, Nam Do and Professor Allen Snyder, is a revolutionary personal interface for human computer interaction; a Brain Computer Interface (BCI) that uses electroencephalography (EEG) brain waves. The inclusion of the EPOC controls strengthens what is already deemed an incredible groundbreaking BCI design; pushing the boundaries of designer thoughts.
This is about flow again (just as in online learning activities). Unfettering the minds will really get the creative juices going. The Emotiv EPOC uses a set of 14 sensors plus 2 references to tune into electric signals produced by the brain to detect the user´s thoughts, feelings and expressions in real time. Based on the latest developments in neuro-technology, Emotiv has developed a revolutionary new personal interface for human computer interaction. The Emotiv EPOC is a high resolution, neuro-signal acquisition and processing wireless neuroheadset that allows users to experience the fantasy of having supernatural powers and controlling the world with your mind.
The original goal of the company was to pioneer more realistic and human computer interfaces using mental cues and unconscious responses from the user. To do this, the company envisioned a low-cost, consumer-friendly, wireless, multi-channel EEG headset.

Emotiv targeted its initial product towards gaming applications, because that promised volume sales and high earning potential, but also because gaming provides a good benchmark for the system’s user-friendliness and robustness during everyday use.
For brain signal acquisition, Emotiv engineers used a high-quality front-end amplifier system, multiplexed to a 16-bit analogue-to-digital converter that passes samples at 2048Hz/channel to a Microchip dSPIC processor. 

The headset is capable of detecting four mental states, 13 conscious thoughts and facial expressions (through electromyography, the recording of electrical activity of muscle tissue). In addition, the device uses two gyroscopes to sense head movements. Today, Emotiv sells applications for brain-controlled photo viewing, brain mapping, games and brain-controlled keyboards, plus developer tools.
