Dynamic Cursor Icon for Input Mode Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses, such as smart TVs, lack intuitive feedback on user input modes and commands, leading to user distraction and inconvenience, as they display a standard cursor regardless of input method.
Innovation Solution
A display apparatus with an image processor, display, and controller that processes user inputs to display a cursor as an icon showing the operational state of the input, including input modes like remote controller, mouse, gesture, and voice inputs, and commands like roll-over, pushing, and loading, with animation effects to provide visual feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard cursor is displayed regardless of input mode, then the display apparatus maintains simplicity in cursor rendering, but the user cannot intuitively identify the input state or obtain feedback on the input result
Solution Approach 1:
The patent applies local quality by changing the cursor icon's appearance based on the specific input mode being used. Different input modes (remote controller, mouse, keyboard, voice, gesture, touch) are represented by distinct cursor icons, allowing users to intuitively identify the current input state at the local level of the cursor display without complicating the overall system architecture.
Solution Approach 2:
The patent utilizes color changes and visual modifications of the cursor icon to indicate different operational states such as roll-over, pushing, waiting, and loading. This provides intuitive visual feedback to users about the current input state and system status, improving ease of operation through visual cues.
2Loss of information
If the cursor icon changes to show operational state, then the user can intuitively identify input state and obtain feedback, but the display system becomes more complex in processing and rendering different cursor states
Solution Approach 1:
The patent implements feedback by displaying cursor icons that reflect the current operational state of the input device. The controller receives input signals, determines the operational state (roll-over, pushing, waiting, loading), and updates the cursor icon accordingly. This feedback loop provides users with real-time information about their input actions and system status, reducing information loss.
Solution Approach 2:
The patent applies dynamics by making the cursor icon adaptive and changeable based on the input mode and operational state. Instead of a static cursor, the system dynamically selects and displays appropriate cursor icons that correspond to the current state, allowing the display to respond flexibly to different input conditions without requiring complex processing for each individual case.
3Ease of operation
If animation effects are added to the icon, then visual feedback is enhanced and user interaction is improved, but the processing power and energy consumption increase
Solution Approach 1:
The patent uses periodic action through animation effects on the cursor icon to provide enhanced visual feedback. Animations such as blinking, pulsing, or rotating effects are applied to indicate specific operational states or to draw user attention to the cursor location. These periodic visual variations improve ease of operation by making the cursor more noticeable and the feedback more engaging, while consuming minimal additional energy compared to static displays.

AI summary
A display apparatus and a control method thereof for displaying an operational state of a user input are provided. The display apparatus includes: an image processor configured to process an image signal; a display configured to display an image thereon based on the processed image signal; a user input configured to receive a user's input; and a controller configured in response to the user's input being received, control the display to display thereon a cursor moved in correspondence with a location of the user's input as an icon showing an operational state of the user's input. Thus, a user may intuitively recognize the operational state of the user's input and may obtain prompt feedback on the input result without suspending his/her interaction.
