Grip-Sensing Control Device for Broadcast Menu Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing broadcast receivers require users to perform input operations on a remote controller while checking the receiver's image medium from a distance, making it inconvenient to select desired menus.
Innovation Solution
A control device that communicates with a broadcast receiver to determine a control mode based on user grip direction, allowing menu display on either the receiver or the control device, and enabling command input through a user interface optimized for the selected mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If menu information is displayed only on the broadcast receiver, then the receiver's display function is utilized, but the user must operate the remote controller from a distance without clear visual feedback
Solution Approach 1:
The patent introduces a control device as an intermediary between the user and the broadcast receiver. This control device receives menu information from the receiver and displays it locally, providing visual feedback to the user without requiring them to view the receiver's display from a distance. The intermediary resolves the contradiction by decoupling the display function from the receiver while maintaining the control function.
Solution Approach 2:
The patent extends the display function to a new spatial dimension by implementing a control device that can display menu information separately from the broadcast receiver. This creates a second display dimension, allowing users to view menu information on the control device while the receiver continues to display content, thus solving the visual feedback problem without compromising the receiver's display capabilities.
2Ease of operation
If the control device displays both menu information and control interface, then user convenience is improved, but the control device's interface complexity increases
Solution Approach 1:
The patent segments the interface into distinct functional areas: a menu information display area and a control interface area. This segmentation allows each area to serve its specific purpose without interfering with the other, reducing the perceived complexity for the user while maintaining comprehensive functionality. The control device processes different types of information separately, simplifying the user interaction model.
3Adaptability or versatility
If the system adapts control mode based on grip direction, then user preference accommodation is improved, but the system complexity increases
Solution Approach 1:
The patent replaces complex mechanical or manual adjustment mechanisms with an automatic sensor-based system. The gyro sensor automatically detects the grip direction and triggers the appropriate control mode without requiring user intervention or complex decision logic. This substitution simplifies the user interaction while maintaining high adaptability, as the system automatically adjusts to different usage scenarios.

Data Source
AI summary
A method for controlling a control device includes receiving, from a broadcast receiver, first information regarding a content which is currently provided through the broadcast receiver, and displaying a UI corresponding to the content which is currently provided through the broadcast receiver among a plurality of UIs based on the received first information. The plurality of UIs includes a plurality of UI items for controlling the broadcast receiver, respectively. A control command is transmitted to the broadcast receiver in response to a user input selecting an UI item among the plurality of UI items for controlling the broadcast receiver.
