Ideal Interface Specifications for Invoking P300?
Posted: 02 Nov 2009, 09:06
Hello,
I am currently working with a team to develop an environmental control interface using BCI2000 for the P300 wave, but are only in the initial conceptual design phase. We were hoping to gain some knowledge of ideal or standardized P300 speller interface specifications.
After consulting some sources, it was determined that a 3x3 or 4x4 matrix was ideal for our interface. However, we wish to know if there is an ideal size for the icons on the screen, or how much of the screen the matrix should take up with regards to the display area as a whole. In addition, we would also like to know if there is a standardized interval between the screen flashes and how long each row or column is lit up for.
Any assistance regarding this matter would be greatly appreciated.
