Wearable Motion Sensor Intermediary for Distant Gesture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices that use infrared sensors for gesture detection are inconvenient as they require direct contact or proximity, limiting the ability to operate the device from a distance, especially in environments like kitchens where movements during cooking can inadvertently trigger unwanted actions on the screen.
Innovation Solution
An electronic device with a communication interface and a motion sensor system, including an acceleration sensor, gyro sensor, and barometric pressure sensor, that communicates with a movement detection apparatus to detect and interpret user movements, allowing the device to update the screen accordingly, enabling operation from a distance and reducing accidental interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If infrared sensors are used for gesture detection, then the device can detect user gestures, but the device requires direct contact or proximity which limits operation from a distance
Solution Approach 1:
The patent introduces a movement detection apparatus as an intermediary device that wears on the user's body. This apparatus contains motion sensors that detect movements locally, and then communicates this data to the electronic device. This intermediary approach allows the electronic device to operate from a distance while maintaining reliable gesture detection through the wearable sensor that moves with the user's body.
2Ease of operation
If motion sensors are continuously activated for gesture detection, then gesture detection is always available, but power consumption increases
Solution Approach 1:
The patent implements periodic action by having the controller activate motion sensors only when specific conditions are met, such as when a particular screen is displayed or when gesture detection is needed. The sensors are deactivated during periods when they are not required, creating an on-demand detection system that maintains gesture detection availability while significantly reducing overall power consumption compared to continuous operation.
3Measurement precision
If all motion sensors are activated simultaneously, then comprehensive movement detection is achieved, but device complexity and power consumption increase
Solution Approach 1:
The patent applies dynamics by making the sensor activation state changeable based on operational needs. Different motion sensors (acceleration sensor, gyro sensor, barometric pressure sensor) are activated dynamically according to the current screen context and detection requirements. This dynamic activation strategy maintains comprehensive movement detection capability when needed while reducing device complexity and power consumption during normal operation by keeping sensors inactive until required.

AI summary
An electronic device includes a communication interface, a display, and a controller. The communication interface communicates with a movement detection apparatus including a motion sensor that detects a predetermined movement of a user. The controller activates the motion sensor when a screen displayed on the display is related to the predetermined movement. The predetermined movement includes a plurality of motions, the motion sensor includes a plurality of sensors that detect the plurality of motions, and when the screen displayed on the display is related to one motion among the plurality of motions, the controller activates the sensor that detects the one motion.
