Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If gesture recognition is used for user interaction, then the interface can support complex operations, but the system becomes less flexible and requires pre-registered gestures
Solution Approach 1:
The patent replaces the mechanical gesture recognition system with a magnetic field-based detection system. Instead of requiring users to perform pre-registered physical gestures, the system detects magnetic field changes caused by magnetic stickers placed on objects, enabling direct and flexible object manipulation without gesture learning curves.
Solution Approach 2:
The patent introduces magnetic stickers as an intermediary between the user and the objects. These stickers act as mediators that carry magnetic signatures, allowing the interface to identify and manipulate objects directly through magnetic field detection rather than through complex gesture recognition.
2Reliability
If camera-based gesture recognition is used, then the interface can detect user actions, but it fails in dark environments
Solution Approach 1:
The patent replaces the optical camera-based detection system with a magnetic field-based detection system. Magnetic field detection is independent of light conditions, allowing reliable object identification and interaction in dark environments where camera-based systems fail.
3Ease of operation
If touch panel alone is used for object manipulation, then the interface is simple to operate, but it lacks flexibility for 3D object control
Solution Approach 1:
The patent merges the simple touch panel interface with magnetic field detection capabilities. The touch panel maintains its simplicity for basic interactions while the magnetic detection system adds 3D spatial awareness and object identification, combining the advantages of both approaches.
Solution Approach 2:
The patent creates a multi-functional interface where the touch panel serves both as a simple input device and as part of a comprehensive object manipulation system. The magnetic detection capability enables the same interface to handle both 2D touch interactions and 3D object control universally.
Data Source
AI summary
An information processing device includes a touch panel that detects a first user input, a communication unit that communicates with a portable terminal which detects a second user input, a data obtaining unit that obtains content data including an operable object, a display output unit that outputs a content image which displays the object, and a control unit that controls an operation of the object displayed in the content image, wherein the control unit executes a first operation of the object if the first user input is detected by the touch panel, and executes a second operation of the object if the second user input is received from the portable terminal by the communication unit.
