Motion-Sensing Display Feedback UI for Intuitive Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices using four-way buttons and enter buttons for manipulating highlights are less intuitive and require precise movements, leading to inconvenience in selecting display items, especially when the highlight is moved in a direction different from the user's intention.
Innovation Solution
A method and apparatus that display feedback UI in a region of a display item corresponding to the motion direction of an input device, using a remote controller with a motion sensor, where the feedback UI is displayed on specific faces of the display item based on the motion direction, size, and rotation, and is removed when the input device moves beyond a preset value, allowing for intuitive and precise manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a four-way button and enter button are used to manipulate the highlight, then the display device can perform various functions, but the manipulation becomes less intuitive and requires pressing the button several times
Solution Approach 1:
The patent replaces the mechanical four-way button system with a motion-sensing input device that detects directional movements (up, down, left, right) and directly translates them into highlight movements on the display screen. This substitution eliminates the need for multiple button presses and makes manipulation more intuitive by directly mapping physical motion to on-screen navigation.
2Measurement precision
If a pointer is used to manipulate the highlight, then precision manipulation is possible, but it is inconvenient for the user to select the display item and the highlight may move in a direction different from the user's intention
Solution Approach 1:
The patent implements a feedback mechanism where a feedback UI element is displayed on the display screen in response to the motion direction of the input device. This feedback provides visual confirmation to the user about the intended direction of highlight movement, preventing accidental misdirection and enhancing the user's confidence and control during the selection process.
3Measurement precision
If precision manipulation is required to position the highlight using a pointer, then the display item can be accurately selected, but the operation becomes inconvenient and complex
Solution Approach 1:
The patent segments the manipulation process into distinct directional movements (up, down, left, right) that correspond to the four faces of the display item. By dividing the selection process into these discrete directional segments, the system simplifies the manipulation process while maintaining precision, as each direction clearly corresponds to a specific face of the display item.

AI summary
Provided are a display device and a method for controlling same. The method for controlling a display device includes: displaying a plurality of display items on a display screen; obtaining the coordinates of a point indicated by an input device; highlighting and displaying a first display item positioned on the coordinates; determining the direction of movement of the input device by using the obtained coordinates and coordinates of a moved point, when the point indicated by the input device has been moved; and displaying a feedback UI in a region of the first display item corresponding to the direction of movement of the input device which has been determined.
