Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in accessing and consuming digital content across various devices due to device selection and operability issues, and there is a need for seamless content consumption while moving without interrupting the experience.
Innovation Solution
A projection system that detects and tracks a non-powered display medium, projecting digital content onto it while the user moves, using infrared markers, motion sensing, and facial recognition, and seamlessly handoffs content between zones, maintaining quality through dynamic adjustments in focus, brightness, and tilt.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user moves the display medium to a new location, then the user can consume content in different zones, but the projection may be interrupted or lost
Solution Approach 1:
The projection system dynamically tracks the display medium's location using sensors (camera, RFID, accelerometer) and continuously adjusts the projection beam direction and focus to maintain content projection on the moving medium across different zones
Solution Approach 2:
The system uses feedback from location detection sensors and medium tracking data to continuously adjust projection parameters, ensuring the projected content remains aligned with the display medium as it moves through different zones
2Ease of operation
If the projection system tracks and follows the medium dynamically, then continuous content consumption is enabled, but the system complexity increases
Solution Approach 1:
The system divides the tracking and projection adjustment functionality into separate modules: location detection sensors (camera, RFID), medium tracking algorithms, and projection adjustment mechanisms (lens focus, mirror orientation), allowing independent optimization and maintenance of each component
Solution Approach 2:
The projection system integrates multiple functions into a single device: content projection, location detection, medium tracking, and automatic adjustment, eliminating the need for separate devices and reducing overall system complexity
3Adaptability or versatility
If multiple projection systems are used to cover different zones, then seamless handoff is enabled, but the device complexity and cost increase
Solution Approach 1:
The patent combines multiple projection systems into a coordinated network where systems share location data and content projection state, enabling seamless handoff between zones while maintaining a unified user experience and reducing the need for redundant infrastructure

AI summary
Described herein are systems and techniques for detecting a location of a medium and projecting content onto the medium at the detected location. These systems and techniques also track the changing location of the medium while continuing to project the content onto the medium as the location changes. A user consuming the content on the medium is able to move the display medium relative to a projection device that projects the content without interrupting the consumption of the content.
