Display Key Information Control System for Body Key Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in recognizing and operating body keys on display devices due to their small and unclear markings, leading to frequent incorrect key presses.
Innovation Solution
A key information control system that includes body keys, a detection means (such as infrared, distance, or capacitive sensors) to determine the user's intention to operate the keys, and a key information display controlling unit to show key information at the edge of the display, aligning it with the key positions, providing a clearer and larger image-based interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If body keys are disposed on the display frame directly with small notes, then the display maintains a beautiful appearance and operation is convenient, but the key markings become too small and vague for users to recognize, leading to wrong key presses
Solution Approach 1:
The patent creates a visual copy of the key information on the display screen that corresponds to the physical key positions. This digital representation allows users to see enlarged, clear labels for each key function on the display interface, solving the recognition problem without changing the physical key layout or appearance on the display frame.
Solution Approach 2:
The patent introduces an intermediary layer - the display screen - that mediates between the physical keys and the user's visual perception. By projecting key information onto the display screen at positions corresponding to the physical keys, it bridges the gap between the small physical markings and the user's need for clear recognition.
2Ease of operation
If body keys are disposed on an unscrewable operation control panel, then key recognition is improved, but the device complexity increases and manufacturing cost increases
Solution Approach 1:
Instead of creating a physical copy through a separate control panel, the patent uses the display screen to create a visual copy of the key information. This eliminates the need for additional physical components while providing clear key labeling, thus reducing device complexity and manufacturing cost.
Solution Approach 2:
The display screen serves multiple functions: it displays content, provides key information visualization, and guides user interaction. By making the display multi-functional, the patent avoids adding separate dedicated components for key labeling, thereby reducing overall device complexity.
3Ease of operation
If body keys are disposed on an unscrewable operation control panel, then key recognition is improved, but the manufacturing cost increases
Solution Approach 1:
The patent creates key information visualization on the display screen rather than requiring a separate physical control panel. This approach uses existing display hardware to provide clear key labeling, avoiding additional manufacturing costs associated with producing and assembling separate control panel components.
Solution Approach 2:
The patent changes the state of key information from physical (small markings on a panel) to digital (enlarged visual representations on the display screen). This parameter transformation allows for clear key recognition without the manufacturing complexity and cost of physical control panels.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively reduces incorrect key presses by providing clear and prominent key information, enhancing user operation and eliminating the need for unscrewing panels, thus maintaining the display's aesthetics without increasing manufacturing costs.
Implementation Method 1
the determination unit acquires infrared intensity radiated from the user and sensed by the infrared sensor
Implementation Method 2
the determination unit acquires a distances between the user and the body keys detected by the distance sensors

AI summary
There are provided a key information control system and control method of body keys of a display and a television set, which relates to the display field and is capable of eliminating the problem of pressing a wrong key when the user operates the body keys. The key information control system comprises: the body keys disposed on the display; a detection means disposed in a surrounding area of the body keys, and configured to detect a state of a user relative to the body keys; a determination unit configured to determine whether the user has intention to operate the body keys according to the state of the user relative to the body keys; and a key information display controlling unit configured to control key information of the body keys to be displayed at an edge of a display area of the display in the case that the user has intention to operate the body keys, to make a display position of the key information correspond to a position of the body keys.
