Gesture Input Display Apparatus with Real-Time Visual Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display systems require users to navigate through multiple steps and lack intuitive feedback when issuing commands, making it difficult for users to intuitively know their input state or instantly receive feedback on input results.
Innovation Solution
A display apparatus equipped with a communicator and processor that senses user gesture inputs through sensors, determines corresponding commands, and implements operations based on the sensed gestures, providing immediate feedback through a user interface that includes drawing objects representing the gesture path, allowing for internal and external searches based on gesture characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional button-based input apparatus is used, then device complexity is reduced, but ease of operation deteriorates due to multiple navigation steps and lack of intuitive feedback
Solution Approach 1:
The patent replaces traditional mechanical button-based input with gesture recognition technology. The gesture sensor detects hand gestures in the air, converting physical movements into control commands. This substitution enables more intuitive and direct user interaction while maintaining manageable system complexity through software-based gesture interpretation.
Solution Approach 2:
The patent implements real-time visual feedback by displaying the recognized gesture on the screen as users perform the action. This immediate feedback loop helps users understand the system's response to their gestures, improving intuitiveness and reducing operational errors without requiring complex input mechanisms.
2Productivity
If multiple navigation steps are required for commands, then command specificity is improved, but loss of time increases due to extended navigation procedures
Solution Approach 1:
The patent segments gesture gestures into distinct categories (e.g., pointing, tapping, swiping, pinching) that directly correspond to different command types. Each gesture segment performs a specific function, eliminating the need to navigate through multiple menu levels and significantly reducing the time required to execute commands.
Solution Approach 2:
The system performs preliminary gesture recognition and interpretation before executing commands. By continuously monitoring for gesture inputs and pre-processing the detected movements to identify intended commands, the system can rapidly execute actions without requiring users to navigate through multiple steps, thereby reducing time loss.
3Loss of information
If traditional input methods are used, then device complexity is maintained at low levels, but loss of information occurs due to lack of intuitive feedback on input state
Solution Approach 1:
The patent implements real-time visual feedback by displaying the recognized gesture on the screen as users perform the action. This immediate feedback loop helps users understand the system's response to their gestures, improving intuitiveness and reducing operational errors without requiring complex input mechanisms.
Solution Approach 2:
The system uses color changes and visual effects to provide feedback on gesture recognition status. Different colors indicate different states (e.g., gesture detected, command executed, error conditions), ensuring users receive clear information about the input state without adding significant device complexity.

AI summary
A display apparatus includes a display configured to display an image; a communicator configured to communicate with an input apparatus, the input apparatus including at least one sensor that senses a user's gesture input; and at least one processor configured to, in response to the gesture input being sensed by the sensor of the input apparatus, determine a command which corresponds to the sensed gesture input among a plurality of commands corresponding to a plurality of functions supported by the display apparatus, and implement an operation corresponding to the determined command, and wherein the command corresponding to the gesture input is based on at least one among content and a first user interface displayed on the display, or a user's input prior to the gesture input. Thus, the display apparatus implements operations in response to a user's gesture input, thereby providing more familiar and closer interaction with a user.
