hinkGear is the name of NeuroSky's single dry sensor technology that allows the measurement, amplification, filtering, A/D conversion, data processing and analysis of EEG signals and brainwaves integrated into a piece of ASIC chip. And it outputs eSense parameters (Attention and Meditation) and original EEG data according to standard interfaces, which greatly simplifies procedures of the EEG acquisition and analysis, reduces the costs, and makes the applications of brain waves much easier to the public. ThinkGear technology has been widely used in all the NeuroSky product and its partners' products. people can make human-computer interaction easily by these devices, including observing the users' real-time mental state and controlling them by "thoughts" | ||
