Wrist-worn Display Gesture Activation via Accelerometer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wrist-worn electronic devices often require manual activation to display information, which can be inconvenient for users who want to quickly glance at data without explicit input.
Innovation Solution
The implementation of sensors, such as accelerometers and gyroscopes, to detect user gestures like watch check movements, automatically controlling display visibility based on activity types, allowing for timely and power-efficient display changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display is always on to provide easy access to information, then user convenience is improved, but power consumption increases
Solution Approach 1:
The system performs preliminary actions by detecting user gestures (such as wrist movements or arm positions) before the user actually needs to view information. When a gesture indicating intent to check the display is detected, the display is activated in advance, allowing the user to immediately view information without needing to manually wake the display. This resolves the contradiction by providing easy access (improving ease of operation) while maintaining power efficiency (reducing power consumption) compared to having the display always on.
2Use of energy by moving object
If the display is activated only with explicit user input to save power, then power consumption is reduced, but user convenience deteriorates
Solution Approach 1:
The system implements self-service by automatically detecting user gestures and autonomously activating the display without requiring explicit user input such as button presses or taps. The gesture detection system monitors for specific movements (e.g., wrist raises, arm positions) and automatically triggers display activation when these gestures are detected. This resolves the contradiction by reducing power consumption (compared to manual activation) while improving convenience (automatic response to natural gestures).
Solution Approach 2:
The system replaces the mechanical interaction system (physical buttons, taps, or switches) with a gesture-based detection system that uses sensors to detect body movements. Instead of requiring mechanical user input to activate the display, the system uses optical or other sensors to detect gestures such as wrist movements or arm positions. This substitution maintains power efficiency while significantly improving user convenience, as natural gestures are more intuitive and faster than mechanical inputs.
3Ease of operation
If gesture detection is continuously monitored to enable automatic display activation, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system applies local quality by focusing gesture detection on specific body parts and specific gesture patterns rather than monitoring all possible movements. Instead of analyzing every possible arm motion, the system concentrates on detecting specific local gestures (such as wrist raises, particular arm positions, or specific movement patterns) that indicate intent to view the display. This selective approach reduces the complexity of the detection algorithm and processing requirements while maintaining automatic activation functionality.
Solution Approach 2:
The system uses partial action by activating the display based on detection of specific gesture patterns rather than requiring complete or complex sequences of movements. The gesture recognition system is designed to trigger display activation when specific partial gestures are detected (such as a wrist raise or a particular arm position), without requiring the user to perform complete, complex, or prolonged movements. This partial action approach simplifies the user interaction while maintaining ease of operation, and consequently reduces the complexity of the detection system compared to requiring more elaborate gesture sequences.

AI summary
In one embodiment, an electronic device to be worn on a user's forearm includes a display and a set of one or more sensors that provide sensor data. In one aspect, a device may detect, using sensor data obtained from a set of sensors, that a first activity state of a user is active. The device may determine, while the first activity state is active, that the sensor data matches a watch check rule associated with the first activity state. Responsive to the detected match, the device may cause a change in visibility of the display.
