Gesture-Controlled Remote Control for IPTV Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IPTV systems are limited by their graphical user interfaces, which can only be controlled using simple key-commands via infrared or radio signals, restricting user interaction to the TV screen and lacking gesture control capabilities.
Innovation Solution
A remote control with a touch-sensitive screen and a programmable electronic processor that identifies finger gestures and maps them to predefined control commands, allowing users to control IPTV systems through intuitive and comfortable gestures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional remote control with simple key-commands is used, then the device complexity is low, but the ease of operation is limited and user interaction is restricted
Solution Approach 1:
The patent replaces traditional mechanical button presses with a touch-sensitive screen that detects finger gestures. The touch screen uses capacitive sensing technology to detect finger position, movement, and gestures, converting physical touch into digital signals for controlling the IPTV system. This substitution enables more intuitive and versatile user interaction while maintaining remote control functionality.
2Adaptability or versatility
If gesture-based control is implemented, then the adaptability of the control system is improved, but the difficulty of detecting and measuring gestures increases
Solution Approach 1:
The patent introduces a programmable electronic processor as an intermediary between the touch-sensitive screen and the IPTV system. The processor receives raw touch data from the screen, processes gesture patterns, interprets user intentions, and generates appropriate control commands. This intermediary layer simplifies the detection complexity by handling the complex gesture recognition algorithms and providing a clean interface to the IPTV system.
3Ease of operation
If a touch-sensitive screen with programmable processor is used, then the ease of operation is improved through intuitive gestures, but the device complexity increases
Solution Approach 1:
The patent makes the remote control device universal by integrating multiple functions into a single unit. The touch-sensitive screen with programmable processor can perform various control operations including channel changing, volume adjustment, menu navigation, and gesture-based commands. This multi-functionality consolidates what would otherwise require multiple separate devices or complex button configurations, making the increased complexity worthwhile through enhanced ease of operation.

AI summary
Methods and apparatus for controlling an Internet Protocol Television (IPTV) system by gestures on a remote control involve determining a number of fingers touching a screen of the remote control; identifying at least one characteristic of movement by the fingers; based on the number determined and at least one characteristic identified, finding a corresponding predefined gesture in a set of predefined gestures; and based on the gesture found, generating a corresponding control command to be sent to the IPTV system.
