Head-Mount Display Luminance Control for Data Disturbance Masking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mount type display devices experience uncomfortable user experiences due to image disturbances caused by data communication issues, such as external noise or changes in data transmission rates, which affect the visibility and quality of the virtual image displayed.
Innovation Solution
The device controls the luminance of the image light generation section to degrade the visibility of the virtual image for a predetermined period when data communication disturbances are detected, making it difficult for the user to notice the disturbance, thereby reducing uncomfortable feelings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the head-mount type display device operates normally with data transmission, then the virtual image is displayed with good visibility, but data communication disturbances cause image display disturbances that create uncomfortable user experience
Solution Approach 1:
The control section detects disturbances in data communication before they cause significant image display disturbances, and preemptively reduces the luminance of the image light generation section. This preliminary action prevents the user from noticing the image disturbance by making the display less visible during the disturbance period, thereby maintaining reliable image display without causing user discomfort.
2Object-affected harmful factors
If the luminance of the image light generation section is reduced to mask communication disturbances, then user discomfort is reduced, but the visibility of the virtual image is degraded during the disturbance period
Solution Approach 1:
The control section reduces the luminance of the image light generation section in advance when a data communication disturbance is detected, creating a cushioning effect that masks the image display disturbance. This beforehand cushioning prevents the user from noticing the disturbance by reducing visibility before the disturbance becomes apparent, thereby reducing user discomfort while managing the trade-off with image visibility.

AI summary
A head-mount type display device adapted to make a user visually recognize a virtual image includes an image light generation section adapted to generate image light representing an image using image data and then emit the image light, a light guide section adapted to guide the image light, which is emitted, to eyes of the user, a receiving section adapted to receive the image data, and a control section, which is connected to the receiving section, controls image display by the image light generation section, and has a transmitting section adapted to transmit the image data to the receiving section. The control section controls luminance of the image light generation section so as to degrade visibility of the virtual image for a predetermined period of time in a case in which a disturbance in data communication between the transmitting section and the receiving section is presumed.
