Wireless Control Device Panning and Zooming Large Screen Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for controlling large screen displays, such as those in entertainment ecosystems, lack efficient methods for seamless user interaction and content navigation using wireless portable computers, particularly in scenarios where direct communication between the portable device and display is not feasible.
Innovation Solution
A system that includes a control device with a processor executing instructions to present a user interface with a video image and a movable border, allowing users to pan and zoom content on a display device by sending commands to a controller, enabling intuitive control of video presentation without direct communication between the portable device and the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wireless portable computer is used to control a large screen display, then user mobility and ease of operation are improved, but direct communication between the portable device and display becomes infeasible, requiring an intermediary controller
Solution Approach 1:
The patent introduces a display controller as an intermediary device that receives control commands from the portable computer and translates them into display control signals. This mediator enables wireless portable devices to control large screens without requiring direct communication links, maintaining user mobility while managing system complexity through specialized intermediary hardware
2Area of stationary object
If the entire video image is displayed on the large screen, then the display area is maximized, but the user cannot easily navigate or focus on specific portions of the content
Solution Approach 1:
The patent divides the video content into manageable portions using a border indicator that highlights specific regions of interest. Users can drag this border to segment and select different portions of the video, enabling focused navigation on large screens while maintaining the ability to view the complete content context when needed
Solution Approach 2:
The system allows users to display only the necessary portion of the video content at any given time by dragging the border to select regions of interest. This partial action approach enables focused viewing of specific content areas without requiring the entire video to be visible, improving navigation efficiency on large displays
3Adaptability or versatility
If a border indicator is added to the user interface to enable panning and zooming, then content navigation capability is improved, but the user interface complexity increases
Solution Approach 1:
The border indicator serves multiple functions: it acts as a selection tool for defining regions of interest, a navigation aid for panning across content, and a visual feedback mechanism showing what will be displayed. This multi-functional design enhances content navigation capability without proportionally increasing interface complexity, as a single element performs multiple navigation tasks

AI summary
A multi-window user interface (UI) on a control device such as a tablet computer communicates commands to a display controller, which may be implemented by a game console. The controller controls presentation on a large screen display according to the commands. The control device may always present a multi-window UI which the control device can command to have mimicked on the display, with the UI also being configured to cause a single video to be presented whole screen on the display while the multi-window UI remains presented on the control device. The video feeds that populate the multi-window UI are of the same content but of lower resolution than those which are presented on the display. A movable window on the control device can be dragged and dropped to cause a corresponding magnifying focus on the display over the corresponding portion of video in focus on the control device.
