Abstract

This study proposes the use of radial visual stimuli design to obtain increased steady state visual evoked potential (SSVEP) responses that can be utilised in brain-computer interfaces

Circular rings with diameters 70 mm, 90 mm, 110 mm, and 130 mm with green COB LEDs were used for radial and concentric patterns while green strip COB LED of 18 mm width and length

used were 7, 8, 9 and 10 Hz for a period of 30 seconds for each horizontal, radial and concentric circle visual stimulus. The study analysed the EEG recording from five participants

ring diameters in radial visual stimulus to identify the maximal response and minimal visual fatigue. The results indicated that radial stimulus gave significantly better response than concentric

circles or horizontal stimuli for all the participants. Also 130 mm radial stimulus gave the highest response and viewing comfort.
