Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a light source at a position corresponding to a finger touching a predetermined position is caused to emit light while other light sources are caused not to emit light, then the position of touch is clearly indicated, but the optical presentation becomes monotonous and fails to express movement speed variations
Solution Approach 1:
The patent applies dynamics by making the light emission characteristics changeable based on finger movement speed. The light source's emission intensity and duration are dynamically adjusted according to the detected finger movement speed, transforming a static light indication system into a dynamic one that can express different operational states. This resolves the contradiction by maintaining clear position indication while adding expressive capability for movement variations.
Solution Approach 2:
The patent changes the parameters of light emission (intensity, duration, color temperature) based on finger movement speed detection. By varying these light emission parameters according to the speed at which the finger moves across the input interface, the system provides differentiated optical presentations for different interaction types. This enables the system to maintain precise position indication while expanding the range of optical expression to convey movement characteristics.
2Measurement precision
If multiple light sources are used to indicate different positions, then position indication is achieved, but the system cannot effectively convey the speed and direction of finger movements
Solution Approach 1:
The patent implements feedback by detecting finger movement speed and using this information to adjust light emission characteristics. The system continuously monitors the interaction and provides real-time optical feedback that reflects both position and movement dynamics. This feedback mechanism ensures that position indication remains precise while simultaneously conveying movement speed and direction information through variations in light emission patterns.
Solution Approach 2:
By making the light emission dynamic and responsive to finger movement speed, the system transforms static position indicators into dynamic feedback elements. The light sources not only indicate position but also adapt their emission characteristics based on the detected movement parameters, thereby conveying speed and direction information without sacrificing position indication precision.
3Ease of operation
If simple light on/off control is used, then the system is easy to control, but the user feedback is limited and lacks operational feel
Solution Approach 1:
The patent enhances user feedback by changing multiple parameters of light emission (intensity, duration, color temperature) based on finger movement speed, while maintaining the simplicity of the underlying control system. The control logic remains relatively simple, automatically adjusting light parameters based on detected movement characteristics, thereby providing rich user feedback without complicating the control mechanism.
Solution Approach 2:
The system transitions from static light on/off control to dynamic light emission control that adapts to finger movement speed. This dynamic approach enriches user feedback and operational feel while building upon the simple foundation of light-based control, maintaining ease of operation while significantly enhancing adaptability and feedback quality.

AI summary
An input interface device (11,151) includes at least one processor (11). The processor (11) performs control to cause, among light emitters (151b), a first light emitter (151b) corresponding to a contact/proximity point detected by a detector (151a) to emit light with a luminous intensity higher than that of a remaining light emitter (151b). The contact/proximity point is where an object is in contact with or in proximity to a detection surface. The processor (11) further performs control, while the object is moving along the light emitters (151b) in a state in which the object is in contact with or in proximity to the detection surface, to gradually reduce a luminous intensity of, among the light emitters (151b), a second light emitter (151b) corresponding to a point where the object being in contact with or in proximity to the detection surface once detected by the detector (151a) is no longer detected to put out the second light emitter (151b) in a predetermined time.
