Although some products already exist, brain computer interfaces are still in their early stages of development.  Until now research and experimental development has been mainly confined in well equipped laboratories in universities and technology companies.  Launched by the team behind the OpenBCI project, large-scale manufacture of a low-cost electroencephalography (EEG)-reading headset device, , could help make exploratory brain computing more accessible to everyone soon.  The fully programmable device is supported by a growing library of open source components for signal processing and data analysis; the headgear is based on an open design, which can be customized on a per-user basis.
