Solution Overview
Problem
Portable electronic devices face challenges in efficiently controlling output devices based on user movement, as existing technologies require significant computing resources and struggle to differentiate between device and user motion, leading to suboptimal user interface interactions.
Innovation Solution
A method and apparatus that utilize first and second motion sensors to generate motion data, allowing a processor to generate third motion data representing the user's movement independent of the device's movement, enabling the control of output devices such as displays and speakers based on this data, thereby enhancing user interface interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If motion capture and motion tracking technologies are used to control output devices, then user interface interactions can be enhanced, but significant computing resources are required
Solution Approach 1:
The motion data from multiple sensors is segmented and processed separately to determine device movement versus user movement. The processor divides the motion analysis into distinct components, evaluating sensor data independently before combining results to control output devices, thereby reducing overall computational burden.
Solution Approach 2:
Motion data is pre-processed and evaluated before being used to control output devices. The system performs preliminary analysis of sensor data to distinguish between device movement and user movement in advance, preparing control decisions beforehand to reduce real-time computational requirements.
2Measurement precision
If existing technologies are used to control output devices, then user movement can be detected, but the device cannot differentiate between device and user motion
Solution Approach 1:
The system segments motion detection into two independent evaluation processes: one for device movement and one for user movement. Multiple sensors are evaluated separately to determine their respective contributions to overall motion, allowing precise differentiation between device and user motion without information loss.
Solution Approach 2:
The processor acts as an intermediary that receives and evaluates data from multiple motion sensors, separating the interpretation of device movement from user movement. This intermediary processing layer enables accurate differentiation by independently analyzing sensor inputs before generating control signals for output devices.
3Measurement precision
If multiple motion sensors are used to track user movement, then control precision can be improved, but device complexity increases
Solution Approach 1:
Data from multiple motion sensors is merged and evaluated together to control output devices. The system combines information from various sensors in a unified processing approach, allowing precise control while managing complexity through integrated rather than separate handling of sensor inputs.
