This animation demonstrates software-based BFI for reducing display motion blur. Photosensitivity Notice: Contains Flicker

Display persistence (pixel visibility time) create display motion blur. Long pixel visibility time means pixels can be blurred across your retinas during eye tracking. This creates perceived display motion blur (MPRT). For more, see Eye Tracking Motion Blur Demo as well as Moving Picture Response Time (MPRT) Demo.

There are many methods to reduce display motion blur:

• Higher frame rates on higher refresh rates. Big geometric differences become human visible, as seen in 120Hz vs 480Hz OLED.
• Flicker-based display refreshing (CRT, plasma, etc) that shorten frame visibility time. Also simulatable in software too, see CRT Electron Beam Simulator.
• Hardware-based backlight strobing, often found in gaming monitors, such as ULMB, DyAc, ELMB, PureXP, etc.
• Hardware-based or software-based black frame insertion, including this demo.
