Innovation Solution
A method and system for controlling a digital television that includes presenting a touch layer representation with content elements gradually revealed based on the duration of a touch command, allowing for capacitive touch control and independent selection of content elements, which can be used to access and customize features without disrupting the main control interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional on-screen interfaces are used for digital television control, then basic control functions are provided, but the interfaces become complex with distracting elements and require extraneous actions
Solution Approach 1:
The interface is segmented into multiple touch-sensitive layers that can be independently activated. Each layer contains specific control elements, allowing the system to present only relevant controls based on user interaction depth, thereby simplifying the visible interface while maintaining comprehensive functionality.
Solution Approach 2:
The interface dynamically adjusts its complexity based on touch duration. Short touches reveal basic controls, while longer touches progressively reveal additional layers of controls. This dynamic adaptation allows the interface to remain simple for routine operations while providing access to advanced features when needed.
2Adaptability or versatility
If conventional fixed interfaces are used, then manufacturing consistency is maintained, but customization options are limited
Solution Approach 1:
The touch-sensitive interface is designed as a universal control system that can adapt to different user preferences and device configurations. The same hardware platform supports multiple interface configurations through software-defined layers, eliminating the need for manufacturer-specific custom hardware while providing versatile control options.
Solution Approach 2:
The interface allows dynamic changing of operational parameters such as touch threshold durations, layer activation settings, and control element visibility. These parameter changes enable customization without requiring physical reconfiguration, maintaining manufacturing simplicity while providing adaptability.
3Ease of operation
If progressive disclosure of content elements is implemented, then user interaction is optimized, but processing requirements increase
Solution Approach 1:
The system performs preliminary actions by pre-defining multiple touch layers and their associated control elements during system initialization. This allows the progressive disclosure mechanism to operate efficiently by simply activating pre-prepared layers based on touch duration, rather than dynamically generating interface elements during user interaction.

AI summary
The present disclosure relates to digital television processes and systems. In one embodiment, a method of controlling a display device includes presenting, by a display device, display content. The display device can receive a touch command indication, wherein the indication is associated with a remote control touch command exceeding a first threshold. The display device can also present a touch layer representation including content elements which are gradually presented based on the duration of the touch command received, determine that the touch command has exceeded a second threshold, and update presentation of the touch layer to display one or more graphical elements in response to the touch command exceeding the second threshold.
