Movable Vehicle Display for Gaze-Aligned External and In-Cabin Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing convenience structures in vehicles provide limited personalized displays both inside and outside the vehicle, failing to adapt to individual occupant needs and environments, especially in autonomous driving scenarios.
Innovation Solution
A movable display system that uses a single display capable of vertical, rotational, and linear movements, controlled by a sensing module and controller to align with the occupant's gaze externally and provide personalized displays internally through rotational movement after boarding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single movable display is used to provide both external and internal displays, then device complexity is reduced, but the ability to provide personalized displays for multiple occupants is limited
Solution Approach 1:
The display device is designed with multiple degrees of freedom including rotational movement around vertical and horizontal axes, allowing it to dynamically reposition and reorient itself. This dynamic capability enables a single display to serve multiple occupants by adjusting its position and orientation based on detected occupant locations and preferences, thereby providing personalized displays without requiring multiple fixed displays
Solution Approach 2:
The movable display system is designed to perform multiple functions: it can display information to occupants inside the vehicle, provide external displays visible from outside the vehicle, and adapt to different viewing positions. By integrating sensing capabilities to detect occupant presence and characteristics, the single display universally serves multiple display needs that would traditionally require separate dedicated displays for each function
2Reliability
If the display provides external display aligned with occupant's gaze, then display effectiveness is improved, but the system complexity increases due to sensing and positioning requirements
Solution Approach 1:
The system incorporates sensing modules that detect occupant presence, position, and gaze direction, providing real-time feedback to the control system. Based on this feedback, the movable display automatically adjusts its position and orientation to align with the occupant's gaze, ensuring optimal viewing without requiring complex manual intervention or overly sophisticated control systems
Solution Approach 2:
The display system autonomously positions and orients itself based on sensor input regarding occupant location and gaze direction. The integrated sensing and control mechanisms enable the display to self-adjust without external intervention, reducing the operational complexity while maintaining high alignment accuracy through automated gaze-following functionality

AI summary
A movable display system and a method therefor are provided. The movable display system includes: a movable display (310); a driving module (320) to realize at least one of a vertical movement of the movable display, a linear movement of the movable display, a rotational movement of the movable display, or any combination thereof; and a controller (330) to control the driving module (320) such that the movable display (310) functions in a first mode of displaying information outside a mobility and a second mode of displaying information inside the mobility.
