Neuro-response data synchronization
View Patent ↗Efficient and effective mechanisms for collecting electroencephalography (EEG) data are provided to synchronize neuro-response data collection with stimulus material presentation for in situ engagement monitoring and tracking. An EEG headset includes multiple point electrodes individually isolated and amplified. In some examples, a stimulus material presentation mechanism includes a clock source and a clock transmitter. The clock transmitter sends clock signals to a neuro-response data collection mechanism to allow synchronization of neuro-response data collected with stimulus presentation events. The EEG headset can be configured to perform processing while supporting both continuous input and output.
1. An apparatus, comprising:
a flexible band;
a first hub coupled to a first end of the flexible band;
a first electrode extending from the first hub a first distance;

a second hub coupled to a second end of the flexible band;
a third electrode extending from the second hub a third distance;
a fourth electrode coupled to the second hub a fourth distance, the fourth distance different than the third distance;
a clock signal receiver to receive a clock signal representing timing information of a stimulus material; and
a processor to synchronize the timing information with neuro-response data gathered from at least one of the first electrode, the second electrode, the third electrode or the fourth electrode.
2. The apparatus of claim 1 , wherein the clock signal receiver comprises at least one of a cell tower signal receiver or a satellite signal receiver.
3. The apparatus of claim 1 further comprising a stimulus material presentation device to present the stimulus material to a user, wherein the clock signal is transmitted from the stimulus material presentation device.
4. The apparatus of claim 1 further comprising a data analyzer to:
analyze neuro-response data gathered from at least one of the first, second, third or fourth electrode while communicatively coupled to a head of a user exposed to stimulus material; and
determine an effectiveness of the stimulus material based on the analyzed neuro-response data.
5. The apparatus of claim 4 , wherein the data analyzer is to analyze the timing information correlating the stimulus material and the neuro-response data, and the effectiveness is further based on the timing information.
6. The apparatus of claim 1 further comprising a transmitter to transmit neuro-response data gathered from at least one of the first, second, third or fourth electrode to a remote analyzer.
7. The apparatus of claim 6 , wherein the transmitter is a wireless transmitter.
