Midair Projection Display Zone Adjustment for User Obstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In smart homes with midair projection displays, existing technologies fail to dynamically adjust the projection zone to avoid obstructing users' views, leading to distractions and obstacles when multiple users are present, as the current systems do not effectively determine and maintain a non-interfering projection area based on individual users' zones of attention.
Innovation Solution
A method that utilizes camera and microphone data analysis to detect multiple users and determine their respective zones of attention, identifying a projection zone that avoids blocking each user's view, allowing for the dynamic adjustment and projection of midair displays in a three-dimensional space, ensuring that the display does not interfere with users' interactions or focus areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the midair projection display is projected near the user's eye for convenience, then the user can easily view the display, but it creates an obstacle to the user and may block the view of other nearby users
Solution Approach 1:
The system transitions from two-dimensional screen-based displays to three-dimensional midair projection displays. By projecting images into the three-dimensional space above the user rather than on a flat surface, the display can be positioned in optimal viewing locations that do not physically obstruct the user's body or create barriers between users, thereby maintaining viewing convenience while eliminating obstructive effects
Solution Approach 2:
The patent introduces cameras and microphones as intermediary sensing devices that capture spatial and auditory information about users. These intermediaries enable the system to indirectly detect user positions, orientations, and zones of attention without requiring direct contact or proximity that would create obstacles, allowing the projection system to adaptively position displays to avoid blocking user views
2Device complexity
If the projection display is placed in a fixed location, then the system structure is simple, but it blocks the view of other associated nearby users when multiple users are present
Solution Approach 1:
The patent implements dynamic positioning of the midair projection display by continuously analyzing camera and microphone data to determine user positions and zones of attention. The projection location is dynamically adjusted based on real-time spatial analysis, allowing the display to move to optimal positions that avoid blocking user views while maintaining a relatively simple overall system structure through automated adaptation
Solution Approach 2:
The system employs feedback mechanisms by using cameras and microphones to continuously monitor user positions and orientations, then using this information to determine appropriate projection zones. This closed-loop feedback system enables the display to automatically adapt to multiple users without requiring complex manual reconfiguration, balancing system simplicity with the ability to avoid blocking user views
