Terminal Device Haptic Unit Emotional State Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current terminal devices primarily use haptic effects for notification purposes, lacking true interaction with users through senses other than vision and hearing, and fail to effectively induce emotional responses beyond basic notifications.
Innovation Solution
A terminal device equipped with a haptic unit that adjusts frequency, strength, and rhythm to provide emotional stimuli, along with input and control units that analyze and match emotional states from various inputs, including images and sounds, to deliver tailored haptic effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If haptic effects are used only for notification purposes, then the device function is simple and reliable, but the user experience and emotional interaction are limited
Solution Approach 1:
The patent applies parameter changes by varying haptic effect parameters (amplitude, frequency, duration, pattern) to represent different emotional states. The control unit adjusts these parameters based on detected emotional inputs, transforming the haptic unit from a simple notification device to an emotional communication interface without requiring hardware redesign.
Solution Approach 2:
The haptic unit is designed to perform multiple functions: traditional notifications and emotional expression. By integrating emotional state detection and corresponding haptic pattern selection, the same hardware component serves dual purposes, reducing overall system complexity while enhancing adaptability.
2Adaptability or versatility
If multiple haptic parameters are adjusted to induce emotions, then the emotional induction capability is enhanced, but the control complexity increases
Solution Approach 1:
The control unit automatically selects and adjusts haptic parameters based on detected emotional states without requiring manual intervention. The system self-regulates by mapping detected emotions to pre-defined haptic patterns, simplifying operation while maintaining complex emotional expression capabilities.
Solution Approach 2:
The system implements feedback by continuously monitoring emotional state inputs and adjusting haptic output accordingly. This closed-loop control ensures appropriate emotional induction while automating the complex parameter adjustment process, making the system easy to operate despite its sophisticated functionality.
3Adaptability or versatility
If haptic effects provide detailed emotional feedback, then the user experience is enhanced, but the energy consumption increases
Solution Approach 1:
The haptic unit operates periodically rather than continuously, activating only when emotional state changes are detected or notifications are required. This intermittent operation maintains high-quality emotional feedback capability while significantly reducing overall energy consumption compared to continuous operation.
Solution Approach 2:
The haptic effect parameters are dynamically adjusted based on the detected emotional state intensity and type. The system applies stronger, more complex haptic patterns only when emotionally significant events occur, while using minimal or no haptic output during stable emotional states, optimizing the balance between feedback quality and energy consumption.
