Holographic Display Viewing Angle Adjustment for User Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Holographic display systems are bulky, costly, and limited to static images or small 3D visual experiences with narrow viewing angles, restricting their application in spaces with limited real estate.
Innovation Solution
The system adjusts the viewing angle of holographic displays based on user direction, using multiple display component subsets to create a combined larger viewing angle and personalize content for multiple users, and employs machine learning to select items based on user accounts and predicted responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If holographic display systems use fixed viewing angles, then device complexity is reduced, but adaptability to different users and locations deteriorates
Solution Approach 1:
The holographic display system dynamically adjusts its viewing angle based on detected user positions and directions. The display device rotates or reorients itself to center the viewing angle on the user, transforming a static display into an adaptive one that follows user movement while maintaining reasonable system complexity through automated control.
Solution Approach 2:
The system uses sensors to detect user position and direction, then feeds this information back to the display control mechanism. This closed-loop feedback enables the display to automatically adjust its viewing angle to match user location, improving adaptability without requiring complex manual configuration.
2Adaptability or versatility
If holographic displays present content for multiple users simultaneously, then user engagement increases, but manufacturing precision requirements deteriorate
Solution Approach 1:
The system dynamically switches between presenting different holographic content to different users based on detected user positions. Rather than attempting to maintain multiple fixed high-precision views simultaneously, the display adaptively redirects its precision output to the current active user, reducing overall manufacturing precision requirements while maintaining multi-user capability.
Solution Approach 2:
The display alternates between serving different users in periodic fashion, adjusting the holographic presentation for each user when they are detected. This time-division approach allows the system to maintain high precision for each individual user view while reducing the need for simultaneous multi-view precision.
3Ease of operation
If holographic displays are made compact, then ease of operation improves, but viewing angle coverage deteriorates
Solution Approach 1:
The compact holographic display compensates for its small size by making the viewing angle dynamic. Instead of requiring a large fixed viewing angle, the compact device can rotate or reorient to track user movement, maintaining broad effective coverage while preserving portability and ease of operation.

AI summary
In some embodiments, holographic presentations despite using holographic displays having limited viewing angles may be facilitated. In some embodiments, a user may be detected via one or more sensors associated with a holographic display system, where the holographic display system being configured with a first viewing angle. Based on the detection of the user, a direction of the user may be determined. The first viewing angle of the holographic display system may also be determined. For example, the holographic display system may determine a current first viewing angle. Based on the direction of the user, the first viewing angle may be adjusted such that the user becomes within the adjusted first viewing angle of the holographic display system.
