Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing music playing applications on electronic devices, such as smartphones, fail to provide a realistic user experience similar to playing an actual instrument, as they only reproduce sounds without simulating the physical action of playing.
Innovation Solution
An electronic device and method that connects with a wearable device through wireless communication to detect motion and transmit control information, allowing users to experience guitar playing by simulating the actions of strumming guitar strings, thereby enhancing the realism of music playing on the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a music playing application reproduces only sounds similar to real guitar sounds, then the sound quality is improved, but the user experience difference from actual instrument playing increases
Solution Approach 1:
The patent replaces the mechanical system of actual guitar playing with an electronic sensing system. Motion sensors detect the user's hand movements and gestures, converting physical actions into digital signals that control sound output. This substitution maintains the realism of the user experience while enabling electronic sound reproduction.
Solution Approach 2:
The patent introduces motion sensors as an intermediary between the user's physical actions and the electronic sound reproduction. These sensors capture the nuances of hand movements and translate them into control signals, serving as a mediator that preserves the authenticity of the playing experience while bridging the gap between physical gesture and digital audio output.
2Ease of operation
If motion detection is added to simulate actual guitar playing actions, then the user experience realism is improved, but the device complexity increases
Solution Approach 1:
The patent applies motion sensors that serve multiple functions: they detect hand movements, determine playing gestures, and control sound reproduction. By making the sensing system multi-functional, the patent reduces the need for separate components for each function, thereby managing device complexity while achieving realistic user experience.
Solution Approach 2:
The motion sensing system automatically detects and interprets user gestures without requiring manual input or configuration. The system self-calibrates by learning from user movements and automatically maps gestures to corresponding musical actions, reducing the complexity of system configuration and operation.
3Ease of operation
If motion sensors are used to detect playing actions, then the ease of operation is improved, but the energy consumption increases
Solution Approach 1:
The patent implements periodic sampling of motion sensor data rather than continuous monitoring. The system activates sensors only when motion is detected or during specific playing phases, reducing overall energy consumption while maintaining responsive gesture control functionality.
Solution Approach 2:
The patent dynamically adjusts the sensitivity and sampling rate of motion sensors based on playing intensity and context. During quiet passages, the system reduces sensor activation to conserve energy, while during intense playing segments, it increases sensitivity to capture nuanced gestures, optimizing the balance between ease of operation and power consumption.
