Engineering Contradiction Analysis
1Use of energy by moving object
If passive electronic displays (LCD, EP) are used, then power consumption is reduced, but the ability to emit light is lost
Solution Approach 1:
The patent merges passive display technology with active light-emitting components (LEDs, OLEDs, or laser diodes) to create a hybrid display system. The passive display panel serves as the base structure while integrated light-emitting elements provide active illumination, allowing the display to function without requiring an external light source while maintaining low power consumption characteristics.
Solution Approach 2:
The display device is designed to perform multiple functions: it acts as both a passive light-modulating display and an active light-emitting device. The integrated light-emitting components enable the display to generate its own light while the passive display layers continue to provide image modulation, creating a multi-functional system that overcomes the limitations of purely passive displays.
2Ease of manufacture
If traditional passive displays are used, then manufacturing simplicity is maintained, but interactivity and user engagement are limited
Solution Approach 1:
The display system is segmented into distinct functional modules: the passive display panel for image rendering, integrated light-emitting elements for active illumination, position sensors for user tracking, and feedback mechanisms for interaction. This modular segmentation allows each component to be optimized independently while maintaining overall system functionality and ease of manufacture.
Solution Approach 2:
Position sensors and feedback mechanisms are introduced as intermediary components between the user and the display. These intermediaries detect user position and provide virtual haptic feedback, enabling interactive engagement without requiring direct physical contact with the display surface, thus maintaining manufacturing simplicity while enhancing user engagement.
3Ease of operation
If contactless interaction is implemented, then user comfort is improved, but system complexity increases
Solution Approach 1:
The patent replaces mechanical contact-based interaction with optical and electromagnetic fields for contactless user detection. Position sensors detect user location through optical or electromagnetic signals, and feedback is delivered through virtual haptic feedback mechanisms, eliminating the need for physical contact while managing system complexity through field-based interaction.
Solution Approach 2:
The system incorporates feedback mechanisms that detect user position and respond with virtual haptic feedback. This feedback loop enables contactless interaction by continuously monitoring user position and providing appropriate responses, improving user comfort while managing system complexity through automated position-based responses.

AI summary
A holographic reality system and multiview display monitor a user position and provide virtual haptic feedback to the user. The holographic reality system includes a multiview display configured to display a multiview image, a position sensor configured to monitor the user position, and a virtual haptic feedback unit configured to provide the virtual haptic feedback. An extent of the virtual haptic feedback corresponds to an extent of a virtual control within the multiview image. The holographic reality multiview display includes an array of multiview pixels configured to provide different views of the multiview image by modulating directional light beams having directions corresponding to the different views and an array of multibeam elements configured to provide the directional light beams to corresponding multiview pixels.
