Glasses-Type Mobile Terminal Seamless Reality Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience dizziness and motion sickness when transitioning from virtual reality images to the real world with glasses-type mobile terminals due to a mismatch between virtual and real-world stimuli, and there is a gap between the virtual and real worlds when returning to reality.
Innovation Solution
A glasses-type mobile terminal that controls virtual reality images by gradually applying a reality image when the user returns to the real world, adjusting movement speeds of virtual objects, and using galvanic vestibular stimulation to minimize disorientation, ensuring a seamless transition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a glasses-type mobile terminal displays a virtual reality image through an opaque display, then the user can view the virtual reality image, but the user may feel dizzy or motion sick due to mismatch between virtual stimulus and real-world stimulus
Solution Approach 1:
The system performs preliminary action by detecting when the user removes the glasses before the user actually experiences dizziness or motion sickness. The controller proactively transitions the display from virtual reality image to reality image in advance, preventing the harmful effect from occurring. This is implemented through a sensor that detects removal of the glasses and triggers an automatic transition sequence.
Solution Approach 2:
The reality image serves as an intermediary between the virtual reality image and the actual real-world view. Instead of directly switching from opaque virtual reality display to real world, the system introduces a transparency transition as an intermediate state, allowing gradual adaptation. This intermediary transition reduces the shock to the sensory system and prevents dizziness.
2Ease of operation
If the glasses-type mobile terminal is removed while a user views a virtual reality image, then the user can return to the real world, but there may be a gap between the real world and virtual reality causing disorientation
Solution Approach 1:
The display transparency is made dynamic rather than static. The controller automatically adjusts the transparency level based on the detected state (wearing vs. removed). When the user removes the glasses, the system dynamically transitions from opaque (virtual reality only) to transparent (reality visible), creating a smooth adaptive experience rather than a abrupt switch.
Solution Approach 2:
The system uses feedback from sensors that detect whether the glasses are being worn or removed. This feedback loop allows the controller to automatically adjust the display behavior - maintaining opaque state during virtual reality viewing and transitioning to transparent state when removed, ensuring reliable sensory adaptation without user intervention.

AI summary
A glasses-type mobile terminal includes a display configured to display a virtual reality image and a controller configured to acquire reality information from a mobile terminal connected to the glasses-type mobile terminal and controlling the virtual reality image if a reality returning time indicating that viewing of the virtual reality image should be finished is reached based on the acquired reality information.
