Smearing along with [[strobing]] is part of the [[judder]] phenomenon in [[head-mounted display]]s. Because smearing reduces the visual quality of the display and even cause [[simulator sickness]], it can ruin a user's [[immersion]]. | ||
Smearing occurs when each pixel moves across the retina while it is lit. The longer the pixels are lit (full persistence) and the more movement of the [[HMD]] (quickly turning your head), the more smearing occurs.<ref name="judder1">http://blogs.valvesoftware.com/abrash/why-virtual-isnt-real-to-your-brain-judder/</ref> | Smearing occurs when each pixel moves across the retina while it is lit.
