Solution Overview
Problem
Current smart loudspeakers provide a limited and mechanical interaction experience for users, lacking intelligence and personalization, resulting in a poor user interaction experience.
Innovation Solution
A control method for audio devices that includes detecting user position, determining a rotation mode for the display screen based on the position, acquiring and displaying corresponding expressions, and controlling the screen to operate according to the rotation mode, allowing differential rotation and expression display to enhance interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed display mode is used, then the device structure is simple, but the interaction experience is poor
Solution Approach 1:
The display screen transitions from a fixed static state to a dynamic adjustable state, allowing real-time rotation based on user position. The screen can rotate to different angles (e.g., 0°, 45°, 90°, 135°) to face users from different directions, making the interaction experience more natural and engaging while maintaining relatively simple control logic through predefined rotation angles.
Solution Approach 2:
The system detects user position through sensors (e.g., cameras, microphones, or position detection modules) and uses this feedback to automatically adjust the display screen rotation angle. This closed-loop feedback mechanism enables the screen to dynamically orient toward the user without requiring manual intervention, improving interaction experience while keeping the control system manageable.
2Adaptability or versatility
If the display screen rotates to face users, then the interaction experience is improved, but the device complexity increases
Solution Approach 1:
The display screen is designed with rotatable capability through a rotation mechanism that can adjust the screen orientation. By implementing predefined rotation angles and positions, the system achieves adaptability to different user positions without requiring overly complex continuous adjustment mechanisms, thus balancing versatility with manageable device complexity.
Solution Approach 2:
The rotation mechanism serves multiple functions: it not only orients the screen toward users but also enables different display modes (e.g., landscape, portrait) and facilitates various interaction scenarios (e.g., single-user, multi-user). This multi-functionality reduces the need for separate mechanisms for each function, thereby limiting the increase in device complexity.
3Adaptability or versatility
If multiple sound apparatuses are used, then the sound coverage is improved, but the device complexity increases
Solution Approach 1:
Different sound apparatuses are positioned at different locations within the device to provide directional sound output. Each sound apparatus is optimized for its specific position and function (e.g., front-facing, side-facing), enabling the system to provide directionally appropriate audio feedback based on user position while maintaining a relatively simple overall structure through localized optimization.
Solution Approach 2:
The system automatically selects and activates appropriate sound apparatuses based on detected user position without requiring manual configuration. This self-service capability allows the device to dynamically adjust audio output among multiple sound apparatuses, providing directional sound coverage while keeping the control system simple and intuitive.
