Blinker

The only device in the world for the accurate generation of any visual stimuli evoking SSVEP potentials.

Blinker is a one-of-a-kind device generating high-accuracy, high-frequency stimuli to BCIs based on the SSVEP paradigm.

SSVEPs are steady-state visual evoked potentials which appear in EEG when the user focuses on a visual stimulus flashing at a constant frequency. The user sees a variety of elements on the screen, selectable by concentrating on a particular element. This leads to an EEG power increase at the frequency corresponding to that element.

Blinker by BrainTech allows for highlighting each of 320 segments of a 15-inch screen independently with various frequencies. This opens unprecedented opportunities for analysis on which part of the screen (movie, picture, ad…) the user is concentrating her/his attention—as opposed to gazing – at the moment. Blinker is delivered with software for designing experiments (PsychoPy).

PARAMETERS

BLINKER

  • 15.6 inch LCD screen
  • LED-backlit screen, 1920 diodes in 320 independent segments
  • possibility to configure any segments into a single controllable “field”
  • possibility to configure any field in terms of:
    • brightness
    • brightness buffer
    • buffer playback frequency (ranged from 0.1 Hz to 60 Hz with the accuracy of up to 0.1 Hz)
    • phase shift
  • possibility to turn on/off and change parameters of any field in real-time
  • micro-controller updates the condition and brightness of any field with a maximum frequency of 10 kHz (every 100 μs)
  • time from a request to response less than 500 μs
  • device global brightness controlled with buttons or relevant instructions
  • galvanically isolated connector for a generation of the synchronized analogue signal:
    • +5 V, -5 V, GND, +SIG inputs;
    • SIG output sends a signal synchronized with the equipment operation as configured via USB
  • image displayed on the screen via HDMI

Blinker will allow you to conduct previously unattainable experiments and research using the precise presentation of visual stimuli.

EXAMPLES OF USE

  • SSVEP-based brain-computer interface design
  • research on various aspects of visual attention
