Feasibility
The typical BCIs are created for research, which are usually beyond the price range of the average consumer. The high cost of quality equipment required to capture biomedical signals, is one of the main limiting factors for wide-spread use of BCIs. Different methods have been attempted to reduce the costs, and bring it to the market. One method requires the use of dry EEG electrodes, which can capture signals without the use of conductive gel. One research team built a complete BCI using low-cost technology, which greatly reduced its costs when compared to clinical-grade BCI. This BCI achieved fairly high accuracy levels, in spite of the increase in noisy signals, showing that it is possible to build a functioning low-cost BCI with a fair performance. The high level of accuracy was mainly attributed to algorithms capable of detecting and filtering EEG data segments.
