Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack the ability to dynamically adjust haptic outputs based on the orientation, position, and operating environment, leading to suboptimal notification salience and user attention.
Innovation Solution
The system and method involve using sensors to determine the orientation, position, and operating environment of an electronic device, allowing it to select and provide tailored haptic outputs, including direction, duration, frequency, and pattern of vibrations, which can be combined with auditory and visual notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If haptic output is provided without considering device orientation and environment, then the notification can be delivered simply, but the salience and effectiveness of the notification is reduced
Solution Approach 1:
The haptic output parameters (intensity, pattern, duration) are dynamically adjusted based on real-time sensor data about device orientation, position, and operating environment. The system transitions from static haptic patterns to adaptive patterns that respond to contextual changes, resolving the contradiction between simple delivery and effective salience.
Solution Approach 2:
The device uses its own built-in sensors (accelerometers, gyroscopes, environmental sensors) to automatically determine orientation and environment, then self-adjusts haptic output without requiring external input or complex external systems. This self-service approach improves notification effectiveness while avoiding the complexity of additional external sensing systems.
2Adaptability or versatility
If multiple sensor inputs are processed to determine device context, then the haptic output can be optimized for the situation, but the processing complexity and time increase
Solution Approach 1:
The system segments the sensing and processing function into distinct modules: orientation sensing (accelerometers, gyroscopes), environmental sensing (light, temperature, proximity), and haptic control. Each module operates independently with defined interfaces, reducing overall system complexity while maintaining comprehensive adaptability across multiple sensor types.
Solution Approach 2:
A unified processing framework handles multiple sensor inputs (accelerometer, gyroscope, environmental sensors) and application contexts through a single adaptive haptic output mechanism. This universal approach allows the system to adapt to various situations without requiring separate processing paths for each sensor type, managing complexity while maintaining versatility.
3Ease of operation
If haptic output parameters are adjusted based on orientation and environment, then user attention is enhanced, but the energy consumption increases
Solution Approach 1:
Instead of continuously monitoring all sensors and adjusting haptic parameters, the system uses periodic sensing at key moments (notification delivery, orientation change events) to determine when adaptation is necessary. This periodic approach maintains user attention effectiveness while significantly reducing the energy consumption associated with continuous sensor processing.
4Ease of manufacture
If simple haptic vibration is used, then the device structure remains simple, but the notification effectiveness in various orientations is suboptimal
Solution Approach 1:
The system maintains a simple haptic actuator structure but achieves enhanced notification effectiveness by dynamically changing output parameters (intensity, frequency, pattern, duration) based on device orientation and environment. This parameter-based adaptation resolves the contradiction between structural simplicity and notification effectiveness, avoiding the need for complex mechanical structures while improving reliability.
