The experiment will run from the minimum to maximum frequency over a fixed position at the center of FOV or 9 different positions across FOV. The first trial (trial 0) is for illustration and HMD alignment, which will be excluded from data processing. If needed, adjust the HMD position such that the target appears at the center of the HMD FOV</li>
