Immersive Engagement in Mixed Reality Measured with Reaction Time

Plausibility illusion is how realistically objects behave, like a full cup of coffee that is upright versus sideways.

University of Massachusetts Amherst researchers have developed a possible system tool to measure the subjective feeling of presence with an objective metric, such as reaction time.

University of Massachusetts Amherst researchers found that reaction time potentially could be used to measure presence (immersive engagement) with mixed reality technology.

The study involved testing participants in modified "Fruit Ninja" mixed reality scenarios.

The researchers observed that presence, which combines place illusion and plausibility illusion, could be manipulated by adjusting the authenticity of the digital elements' appearance.

The researchers adjusted place illusion to make the fruit appear either lifelike or abstract and altered the plausibility illusion by showing mugs filled with coffee either upright or sideways.

They observed quicker reaction times among users reacting to more lifelike fruit and more plausible scenarios for the coffee mug.

The researchers determined that reaction time is a good measure of presence by indicating whether users see the virtual elements as tools or distractions.
