Abstract
The in
uence of changing the visual angle on the performance of a new method used for Brain
Computer Interfaces (BCI), namely Noise-Tag was investigated. This was done by varying the
distance between the subject and the stimuli. Accuracy and speed were compared and the data
was processed with an repeated measures ANOVA. Visual angle had a clear and signi cant
(p-value is .0006) e ect on accuracy. A smaller visual angle resulted in worse accuracy. Barely
any e ect (p-value is .6551) was found on the speed. Furthermore training on di erent visual
angles was tested resulting in a signi cant e ect (p-value is .0114). Training on smaller visual
angles resulted in worse accuracy.
