The Stroboscopic Effect

The stroboscopic effect, also known as temporal aliasing, is a major issue with motion and animation in both interactive and passive virtual environments. It is also seen in meatspace, but only at much higher speeds, albeit for the same reason.

It is a kind of aliasing that occurs when what should be a continuous motion such as a wheel spinning, is instead divided into a series of frames per second, which are then sent to the eye. If the movement speed of the wheel is accidentally synced to the update frequency of the frames, then it appears to not be moving, even as the vehicle drives forwards, resulting in an extremely immersion breaking effect.

As an example, a carriage wheel is turning at 30 revolutions per second, and happens to be being displayed on a monitor that is updating at 30 fps. Every time the monitor updates the view, the wheel has performed one revolution, and is back in exactly the same place it was before. Hence, it appears to be perfectly still, whilst the cart is dragged along the ground.

A slightly worse variant occurs when the wheel is rotating at say, 29 revolutions per second, and the display frame rate is still 30 frames per second. In this instance, the wheel does not manage to complete a full revolution each frame, and actually appears to be moving in reverse.

Looks more important than Sounds in Speech
A neurological experiment has confirmed that the McGurk effect - a long-known phenomenon where what you see overrides what you hear - is indeed codified directly into the sound processing regions of the brain. Meaning the McGurk effect is not something that can be barpassed in our virtual environments, and is not a trick of sensory perception, but rather is a cornerstone of sound perception itself.

Imagination Eases Pain: Study Reinforces Effect Shown by VRs
A study has been performed on the use of imagination in children as a pain blocker. Whilst not directly connected with VR in pain relief itself, the results do serve to reinforce the position that diverting the child's attention elsewhere during a procedure, utterly diverting it and holding that diversion, is successful in removing the effect of pain.

Stroboscopic Memory Training
A method of training the brain through means of stroboscopics bears a striking resemblance to the basic technology underlying all VR display systems. Could VR really be used to enhance memory, even more efficiently than the physical world-based trials?

Nails on a blackboard. It is an unbearable noise, one that sends shivers through anyone who hears it. But why does it do this, and more importantly, how can a virtual environment replicate the effect in any sound?
