Immersive Viewer Distance Sensor Dynamic Scene Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current videoconferencing systems lack immersion and interactive flexibility due to the need for wearable sensors, joysticks, or GUI controls, which can disrupt the experience and require significant space and energy for large displays, while also presenting choppy scene changes with 360° views.
Innovation Solution
An immersive viewing system that uses a movement detector with a distance sensor to dynamically adjust the view on a display based on user movement, allowing seamless navigation of active scenes without the need for attached sensors or controls, employing cameras with pan-tilt servos and range finders for accurate tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wearable sensors, joysticks, or GUI controls are used to control videoconferencing systems, then interaction capability is improved, but user immersion is degraded and device complexity increases
Solution Approach 1:
The patent extracts the control function from wearable sensors, joysticks, and GUI controls, and relocates it to the environment itself through distance sensors and movement detectors positioned in the room. This eliminates the need for users to wear or hold control devices, reducing device complexity while maintaining interaction capability.
Solution Approach 2:
The patent introduces an intermediary system consisting of distance sensors and movement detectors that mediate between the user's natural movements and the videoconferencing system. This intermediary automatically translates physical movement into system control, improving ease of operation without requiring users to learn complex control interfaces.
2Illumination intensity
If large displays are used to provide immersive viewing, then viewing quality is improved, but space requirements and energy consumption increase
Solution Approach 1:
The patent implements dynamic scene navigation where the displayed content automatically adjusts based on the user's distance from the display and movement patterns. This dynamic adaptation allows the system to provide high-quality viewing experiences at smaller display sizes by intelligently framing and focusing content, reducing energy consumption while maintaining viewing quality.
3Adaptability or versatility
If 360° views with multiple cameras are used to provide comprehensive coverage, then scene coverage is improved, but scene change smoothness is degraded due to choppy transitions
Solution Approach 1:
The patent uses distance sensors to detect user position in advance and proactively adjusts the active scene before the user actually moves to a new viewing position. This preliminary action ensures smooth scene transitions by pre-positioning the camera view, eliminating choppy transitions while maintaining comprehensive 360° scene coverage.

Function Achieved in This Case
Enhances user interaction and immersion by allowing users to control active scenes with head or body movement, providing a non-tactile, seamless experience across different locations, and reducing the need for multiple monitors or large displays, applicable in various applications like remote collaboration and video gaming.
Implementation Method 1
a distance sensor configured to detect a distance of the user from the display
Data Source
AI summary
An apparatus, a method of providing scenes on a display and an immersive viewing system is disclosed. In one embodiment, the apparatus includes: (1) a movement detector configured to monitor movement of a user with respect to a display, wherein the movement detector is disengaged from the user and includes a distance sensor configured to detect a distance of the user from the display and (2) an active screen displayer configured to navigate an active scene on the display based on changes in the distance and dynamically provide an updated view of the active scene on the display based thereon.
