Summary
Human reaction time in mixed reality (MR) is affected by virtual object location and real-world scene complexity. Understanding these factors improves immersive technology experiences.
Area of Science:
- Human-Computer Interaction
- Virtual Reality
- Perception Psychology
Background:
- Immersive environments blending physical and digital objects are gaining traction.
- Advancements in visualization devices and rendering techniques increase user accessibility.
- Understanding human perception within mixed reality (MR) remains an area with unexplored aspects.
Purpose of the Study:
- To investigate the impact of scene content on human perception of virtual 3D elements in MR.
- To analyze how virtual object presentation influences user reaction times and detection accuracy.
Main Methods:
- A subjective test was designed using an augmented reality headset.
- Participants reacted to virtual objects appearing randomly in their field of view.
- Detection accuracy was measured via omitted, anticipated, and completed responses, analyzing stimulus location and scene content.
Main Results:
- Human reaction time in MR is influenced by the saliency of the real-world scene.
- Natural body gesture technology and a limited field of view also impact reaction times.
- Specific areas of stimulus presentation (upper, lower, left, right, inner, outer) affected response patterns.
Conclusions:
- Scene content and visual field limitations significantly affect user performance in MR.
- Further research into these perceptual factors is crucial for optimizing MR application design.
- Findings contribute to a better understanding of human-computer interaction in immersive environments.
