Stimulus Specificity of Brain-Computer Interfaces Based on Code Modulation Visual Evoked Potentials - Fig 4

(a) The classification accuracy of each subject as a function of stimulus size; (b) Average classification accuracy across subjects for each stimulus size. The error bars represent standard deviation.</p

Stimulus Specificity of Brain-Computer Interfaces Based on Code Modulation Visual Evoked Potentials - Fig 7

<p>Average classification accuracy across subjects yielded by different lengths of M sequences (i.e. code lengths) (a) and different versions of shifts of the 63-bit M sequence between two adjacent targets (b).The error bars denote standard deviation.</p

The topographic map of sixteen signal electrodes and the ground electrode (Fz).

<p>The seven electrodes over the occipital region (P7, P3, Pz, P4, P8, O1, O2) were selected for data recordings in the experiment.</p

Five square stimuli with different proximities.

<p>The four competing stimuli have the same separation with the central stimulus in both horizontal and vertical directions. Stimuli in (a) are closely placed with visual angle 3.8°; Stimuli in (b), (c) and (d) are separately placed with visual angle 4.8°, 5.8° and 6.8°, respectively.</p
