Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for TV devices require complex finger movements to select functions, making intuitive operation difficult due to their poor operability, especially with simple button configurations.
Innovation Solution
An information processing apparatus equipped with an imaging unit, icon display control, and operation determination unit that displays operation icons and detects hand movements to allow intuitive selection of TV functions by recognizing pixel regions and motion vectors, enabling execution of predetermined processing based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a remote control with many operation buttons is used, then various functions can be controlled, but the operability becomes poor and users must send instructions many times
Solution Approach 1:
The patent replaces the mechanical button-pressing system with an optical recognition system. An imaging apparatus captures images of the user's hand movements, and image processing extracts motion vectors to recognize gestures. This substitution eliminates the need for physical remote control buttons while maintaining comprehensive function control capability.
Solution Approach 2:
The patent creates a visual copy of the user's hand movement on the display screen. The imaging apparatus captures the actual hand movement, processes it to generate motion vectors, and displays the extracted movement trajectory on the screen. This visual feedback copy allows users to see their gestures being recognized, improving ease of operation while maintaining versatility.
2Ease of operation
If a remote control with a simple button configuration is used, then operability is improved, but users must send instructions many times to access hierarchical menus
Solution Approach 1:
The patent introduces dynamic gesture recognition that can adapt to different operation needs. By recognizing the direction, speed, and pattern of hand movements through motion vector analysis, the system can navigate hierarchical menus in a single continuous gesture rather than requiring multiple discrete button presses. This dynamic approach reduces the time to access functions while maintaining simple operation.
Solution Approach 2:
The patent adds the dimension of spatial motion recognition to the control interface. Instead of one-dimensional button pressing, the system recognizes two-dimensional hand movement trajectories captured by the imaging apparatus. This dimensional expansion allows users to access hierarchical menus through continuous spatial gestures, significantly reducing the time required to reach nested functions.
3Adaptability or versatility
If finger movement is required to match menu display objects, then functions can be selected, but intuitive operation becomes difficult
Solution Approach 1:
The patent implements real-time visual feedback by displaying the extracted hand movement trajectory on the screen. The imaging apparatus captures hand movements, processes them to generate motion vectors, and immediately displays these vectors on the display device. This feedback loop allows users to see their gestures being recognized and adjusted in real-time, making the operation more intuitive while maintaining full function selection capability.
Solution Approach 2:
The patent uses visual display of motion vectors to indicate recognized gestures. By presenting the extracted movement information as visible graphical elements on the screen, the system provides intuitive feedback about which function is being selected. This visual indication method makes the relationship between hand movement and function selection more intuitive.
