Solution Overview

Problem

Conventional display screens equipped with modern communication devices are limited to displaying two-dimensional images from a single perspective, making interactive group activities like multi-player gaming less immersive due to the lack of effective solutions for rendering 3D imagery from multiple viewpoints without complex and expensive technologies.

Innovation Solution

A system and method utilizing a single display screen that rotates to display multiple perspectives of an image using illumination switching, incorporating a sensor network and motor control to synchronize the spin rate with the frame rate, allowing observers to view appropriate perspectives based on their location, effectively creating a 3D-like experience without the need for multiple projectors or AR headgear.

1Device complexity

If conventional 2D display screens are used, then device simplicity and cost-effectiveness are maintained, but immersion and engagement in interactive group activities deteriorate

Engineering Contradiction:
Improvedisplay system complexityVSAvoidmulti-perspective viewing capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The display screen is rotated about an axis perpendicular to its surface, transforming from a static 2D display into a dynamic multi-perspective display system. This rotation enables the screen to present different perspectives to observers at different locations, creating a 3D-like experience without requiring complex multiple projector systems or AR headgear.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The illumination source operates in periodic pulses synchronized with the display screen rotation. By controlling the illumination timing to coincide with specific rotational positions, the system displays different perspectives at different times during each rotation cycle, enabling multi-perspective viewing while maintaining system simplicity.

Inventive Principle:
Principle #19Periodic action

2Adaptability or versatility

If 3D imagery is projected using multiple projectors or AR headgear, then multi-perspective viewing capability is improved, but device complexity and cost increase

Engineering Contradiction:
Improvemulti-perspective viewing capabilityVSAvoiddisplay system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the display screen, illumination source, and rotation mechanism into a single integrated system. Instead of using separate projectors or AR headgear for each perspective, one display screen rotates to present multiple perspectives, merging multiple functions into a unified apparatus that reduces overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

A single display screen performs multiple functions by rotating to different orientations, serving as multiple virtual displays for different perspectives. This multi-functional approach replaces the need for multiple dedicated projectors or AR devices, each handling a single perspective, thereby reducing device complexity while maintaining versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the display screen rotates to show multiple perspectives, then multi-perspective viewing capability is improved, but synchronization between spin rate and frame rate becomes more difficult

Engineering Contradiction:
Improvemulti-perspective viewing capabilityVSAvoidspin rate synchronization
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The system employs sensors to detect the rotational position and speed of the display screen, providing feedback to the control circuit. This feedback mechanism enables the control circuit to adjust the illumination timing and spin rate to maintain precise synchronization with the frame rate, overcoming the difficulty of maintaining synchronization during rotation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The control circuit pre-calculates and sets the illumination timing based on the desired spin rate and frame rate before rotation begins. By establishing the synchronization parameters in advance and maintaining a fixed relationship between rotation speed and illumination timing, the system simplifies the synchronization challenge.

Inventive Principle:
Principle #10Preliminary action

AI summary

According to one implementation, a multi-perspective image display system includes a motor configured to spin a rotor, a display screen coupled to the rotor, and a controller. The controller is configured to cause the motor to spin the display screen, using the rotor, about an axis of rotation at a spin rate, and to determine, based on the spin rate, an illumination on-time for an illumination source of the display screen. The controller is also configured to sequentially render each of multiple different perspectives of an image on the display screen during each revolution of the display screen about the axis of rotation and, concurrently with sequentially rendering each of the plurality of perspectives of the image on the display screen, to strobe the illumination source of the display screen based on the determined illumination on-time to display the multiple different perspectives of the image.
