Television User Interface Touch Pad Gesture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic program guides (EPGs) for television systems face challenges in providing intuitive navigation for users due to increased channel options and complexity, with current remote controls requiring excessive button pressing and analog direction controls not providing intuitive control.
Innovation Solution
A user interface for television displays using a remote control with a touch pad that communicates wirelessly, employing periodic touch position sampling with quantized timestamps to reduce latency, and utilizing directional gestures for intuitive control, such as skipping forward or backward during playback and controlling scrolling speed through gestures like swipe and hold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional remote controls with directional keys are used to navigate EPGs, then users can select programmes, but excessive button pressing is required which reduces ease of operation
Solution Approach 1:
The patent replaces mechanical button pressing with voice recognition technology. The voice-activated remote control system captures spoken commands, processes them through speech-to-text conversion, and executes corresponding EPG navigation actions, eliminating the need for multiple sequential button presses and significantly reducing navigation time.
Solution Approach 2:
The voice-activated remote control serves multiple functions: it navigates EPGs, searches for programmes, adjusts playback controls, and accesses information services all through voice commands. This multi-functionality consolidates what would require multiple separate operations into a single unified interface, improving ease of operation across diverse tasks.
2Adaptability or versatility
If EPGs include additional information and functionality, then user capabilities are enhanced, but the complexity of navigating and selecting options increases
Solution Approach 1:
Voice recognition technology replaces complex manual navigation through多层次 menus and buttons. Users can access diverse EPG functionalities and select from numerous programme options by speaking natural language commands, which the system interprets and executes, thereby managing interface complexity while preserving extensive adaptability.
Solution Approach 2:
The voice-activated system automatically processes and interprets user intentions without requiring manual navigation through complex interfaces. The system self-manages the complexity of translating voice commands into appropriate EPG actions, programme selections, and information retrieval, allowing users to benefit from enhanced functionality without directly engaging with interface complexity.
3Ease of operation
If analog direction controls are used in remote controls, then navigation capability is improved, but integration with EPG and intuitiveness are insufficient
Solution Approach 1:
The patent replaces analog directional controls with voice-based navigation. Instead of requiring users to interpret and manually execute directional movements on a touchpad or motion sensor, the system accepts natural language voice commands that directly translate to EPG navigation actions, significantly improving intuitiveness while maintaining enhanced navigation capability.
Solution Approach 2:
The voice recognition system automatically detects and interprets user intent from spoken commands without requiring the user to manually control a pointer or interpret analog signals. The system self-manages the translation of voice input into precise EPG navigation, making the interaction more intuitive while preserving navigation effectiveness.

AI summary
A user interface for a television display includes a remote control with a touch pad. The remote control communicates wirelessly with a receiver. Periodic samples of touch positions are time stamped only when they are received at the receiver, and the time stamps are quantized to the interval of the periodic samples. The response of the user interface to gestures may be determined by a set of cascaded style sheets. Directional gestures may be used to skip forward or backward by a relative time during playback. During EPG scrolling, a position indicator may remain fixed in a horizontal direction until a time boundary of the EPG is reached, at which point the position indicator may move to the end of the time boundary. When scrolling programme items, an item may remain highlighted until it scrolls off the display, at which point the highlighting disappears until scrolling is complete. During scrolling, multiple directional gestures may be used to increase speed of scrolling. A swipe and hold gesture may be used to control the speed of scrolling, which is dependent on the length of time of the hold.
