Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses and remote control devices face challenges in recognizing touch inputs from insulators and require large areas for circuit components, leading to increased manufacturing costs and complexity, necessitating a more intuitive and cost-effective single input system for user operations.
Innovation Solution
A display apparatus with an input unit that includes a single physical function key or touch panel, utilizing a processor to distinguish between short clicks and long presses based on input time, maintaining execution speed within a preset critical time and accelerating it thereafter, while providing on-screen guidance for user operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touch sensor is used to control display apparatus functions, then user operation recognition is improved, but insulator materials cannot be used and touch may not be recognized
Solution Approach 1:
The input unit is designed to accept multiple types of user operations (touch, click, long press) through a single unified interface, making it compatible with different interaction methods and materials while maintaining reliable operation recognition
2Ease of operation
If jog switch or tact switches are used to control display apparatus, then user operation recognition is improved, but manufacturing costs increase and circuit board area increases
Solution Approach 1:
Multiple input functions (touch sensing, click detection, long press recognition) are merged into a single input unit, eliminating the need for separate jog switches and tact switches, thereby reducing component count, manufacturing cost, and circuit board area
Solution Approach 2:
The single input unit performs multiple input functions that would traditionally require separate components, reducing overall device complexity and manufacturing costs while maintaining full operational capability
3Ease of manufacture
If single input device is applied to display apparatus, then manufacturing cost and device complexity are reduced, but operation intuitiveness and ease of use may be compromised
Solution Approach 1:
The input unit dynamically responds to different user interactions by detecting touch duration (short click vs. long press) and intensity, providing context-aware functionality that enhances operational intuitiveness despite using a simplified single-input design
Solution Approach 2:
The system provides visual feedback through the user interface to confirm recognized input types (short click, long press), helping users understand the system's interpretation of their actions and improving the overall ease of operation
4Measurement precision
If long press input is continuously processed at full sampling rate, then input recognition accuracy is maintained, but energy consumption increases
Solution Approach 1:
The processor uses periodic sampling at different rates depending on the input state: high-rate sampling during initial press recognition and lower-rate sampling during sustained long press, reducing energy consumption while maintaining accurate input detection
Solution Approach 2:
The sampling rate dynamically adjusts based on the input phase: full sampling rate during the critical initial period for accurate short click vs. long press differentiation, then reduced sampling rate for the remainder of the long press duration, optimizing energy efficiency

AI summary
A display device is provided. The display apparatus includes: a display configured to display a user interface screen; an input interface configured to receive a user operation to select and execute at least one menu item included in the user interface screen; and a processor configured to separately recognize a short click and a long press based on an input time of the user operation, constantly maintain an execution speed of a function corresponding to a selected menu item within a preset critical time in the time for which the input of the long press is continued and accelerate the execution speed of the corresponding function after the preset critical time passes.
