Wearable Device Gesture Control for Driving Context
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices often perform unintended operations due to their functions, causing user inconvenience, especially when the user is driving a vehicle.
Innovation Solution
A wearable device equipped with a sensor unit to detect user movements and a control unit to determine the user's state, allowing it to operate in a mode that performs preset functions or avoids them, and enabling communication with vehicles to enhance user convenience during driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wearable device provides various functions based on collected information, then the functionality and versatility are improved, but unintended operations occur causing user inconvenience
Solution Approach 1:
The control unit continuously monitors sensor data and user actions, comparing detected movements against predefined criteria to determine whether to activate or suppress functions. This feedback mechanism ensures that functions are only executed when genuine user intent is detected, preventing unintended operations while maintaining full functionality availability
Solution Approach 2:
The wearable device dynamically adjusts its operational state based on real-time sensor input. The system transitions between different operational modes (active vs. inactive) depending on whether user movements meet the threshold for intentional interaction, allowing the device to adapt its behavior to the current context
2Ease of operation
If the wearable device detects user movements to activate functions, then the ease of operation is improved, but false gesture triggers occur causing unintended operations
Solution Approach 1:
The system adjusts the sensitivity threshold for gesture detection based on contextual parameters such as detected activity state and movement patterns. By dynamically changing the parameter thresholds for what constitutes a valid gesture, the system maintains ease of operation for genuine user actions while filtering out false triggers from incidental movements
Solution Approach 2:
The control unit pre-establishes criteria for valid gestures and uses preliminary sensor data analysis to predict whether detected movements are likely to be intentional. This preliminary assessment allows the system to prepare appropriate responses while avoiding activation from accidental movements
3Adaptability or versatility
If the wearable device operates with full functionality during driving, then the versatility is improved, but user safety and convenience deteriorate due to unintended operations
Solution Approach 1:
The system applies different operational rules to different functions based on the driving context. When driving is detected, the system selectively suppresses functions that could cause distraction or unintended operations while maintaining availability of essential functions, creating localized quality differences in function accessibility

AI summary
Disclosed are a wearable device and a method of controlling the wearable device. The wearable device includes a sensor unit configured to detect at least one movement of the wearable device, and a control unit configured to determine a state of the wearable device based on the at least one detected movement, and to control, based on the determined state, the wearable device to operate in a first mode of performing a preset function of the wearable device or in a second mode of not performing the preset function.
