Digital TV Control via Voice and Gesture Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital TV control systems are inconvenient as they require separate applications and processes for controlling devices beyond basic functions, limiting user interaction and functionality, especially when using smartphones or other devices instead of traditional remote controllers.
Innovation Solution
A system that allows control of digital devices using embedded functions of controlling devices without additional applications, utilizing voice, gesture, and network connectivity to enable intuitive control of targeted devices, including digital TVs, through voice recognition and gesture recognition interfaces, allowing control from neighboring devices without the need for specific pairing or installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate application is installed on a smartphone to control a digital TV, then control functionality is provided, but device complexity and user inconvenience increase due to installation and execution requirements
Solution Approach 1:
The digital TV is designed to function both as a display device and as a controlling device. The TV's built-in controller can directly control other digital devices without requiring a separate smartphone application, thereby eliminating the need for additional software installation and execution while maintaining control functionality.
Solution Approach 2:
The controlling device utilizes its own embedded functions and resources to perform control operations. The TV's controller serves itself and other devices by leveraging the TV's existing hardware capabilities (camera, microphone, processor) without needing external smartphone applications.
2Ease of operation
If traditional remote controllers or smartphone applications are used, then basic control functions are available, but diverse functions and scenarios require separate program installations
Solution Approach 1:
The controlling device is designed with universal control capabilities that can handle both basic control functions and diverse advanced scenarios through a single integrated system. The controller uses voice recognition, gesture recognition, and camera-based object recognition to provide adaptable control for various functions without requiring separate applications.
Solution Approach 2:
The control system dynamically adapts its operation mode based on the detected scenario. It can switch between voice-based control, gesture-based control, and automatic object recognition control depending on the user's needs and environmental context, providing both ease of operation for basic functions and versatility for diverse scenarios.
3Ease of operation
If voice and gesture recognition are implemented, then intuitive control is achieved, but processing time and system complexity increase
Solution Approach 1:
The controller continuously monitors the environment using its camera and microphone, pre-processing sensory data in real-time. When a control command is detected (such as a recognized voice or gesture), the system is already in a state ready to quickly execute the appropriate control action, thereby reducing the perceived processing time for the user.
Solution Approach 2:
The system replaces traditional mechanical button-pressing interfaces with voice and gesture recognition. By using the TV's built-in camera and microphone along with its processor, it directly translates physical gestures and spoken commands into control signals, eliminating the need for separate remote controllers and reducing the time required to initiate control actions.
4Ease of operation
If paired remote controllers are used, then control is limited to pre-decided functions, but user mobility is restricted as users must locate the remote controller
Solution Approach 1:
The digital TV itself serves as the controlling device, eliminating the need for separate remote controllers. Since the TV is stationary and the user approaches it to watch content, the control function is naturally integrated into the device the user is already interacting with, providing both accessibility and location flexibility.
Solution Approach 2:
The control function is merged with the display device. Instead of having a separate remote controller that must be located and used, the TV incorporates control capabilities directly, combining the functions of display and control into a single integrated system that eliminates the need for users to search for or handle separate control devices.
