Wearable Position Sensor Alerts for Arm-Mounted Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices, such as optical scanners and mobile computers, often suffer from improper positioning on a user's arm, leading to occlusion of the field of view, reduced scanning efficiency, and user discomfort due to ergonomic issues.
Innovation Solution
The wearable device includes a sensor that determines its position relative to a calibrating object, such as the user's hand or a marked glove, and alerts the user through audio, visual, or haptic feedback when improperly positioned, allowing for real-time adjustments to maintain optimal scanning and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the wearable device is placed on the user's arm without position monitoring, then the device can be worn freely, but the field of view may be occluded and scanning efficiency reduced
Solution Approach 1:
The patent implements a feedback mechanism where the sensor continuously monitors the wearable device's position relative to the user's hand and provides real-time feedback through alerts when mispositioning is detected. This allows the user to adjust the device to maintain optimal scanning efficiency without requiring complex automated positioning systems.
Solution Approach 2:
The system employs self-service by using the wearable device's own sensor to monitor its position and generate alerts for user adjustment. The sensor leverages the device's existing capabilities to detect hand proximity and provide positioning feedback, eliminating the need for external monitoring equipment.
2Reliability
If the wearable device includes position detection and alert features, then proper positioning can be maintained, but the device complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the sensor continuously monitors the wearable device's position relative to the user's hand and provides real-time feedback through alerts when mispositioning is detected. This allows the user to adjust the device to maintain optimal scanning efficiency without requiring complex automated positioning systems.
Solution Approach 2:
The patent replaces complex mechanical positioning systems with an optical sensor-based detection system. Instead of using mechanical guides or physical constraints to ensure proper positioning, the system uses optical sensing to detect hand proximity and provides electronic alerts, simplifying the mechanical design while maintaining positioning accuracy.
3Measurement precision
If the sensor continuously monitors position, then positioning accuracy is maintained, but energy consumption increases
Solution Approach 1:
The patent implements periodic monitoring where the sensor checks position at defined intervals rather than continuously. The system determines position at periodic intervals and only activates alerts when mispositioning is detected, reducing energy consumption while maintaining adequate positioning accuracy for scanning operations.

AI summary
Methods, apparatus and computer program products for alerting a user of a wearable device to adjust the position of the device are provided. An example method includes receiving environment data from a wearable device sensor connected to the wearable device, wherein the wearable device is mountable on an arm of the user such that the wearable device sensor is directed toward a hand of the user. Additionally, the example method determines a position of the wearable device on the arm of the user relative to a calibrating object based at least in part on the captured environment data. Further, the example method alerts the user to adjust the position of the wearable device in an instance in which the position of the wearable device relative to the calibrating object exceeds a predetermined threshold.
