HMD Notification Control via Mobile Device Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-mounted displays (HMDs) and mobile devices face challenges in providing effective notifications for events, particularly when the mobile device is positioned outside the camera's view angle or not facing the user, leading to difficulties in recognizing events such as text messages or calls.
Innovation Solution
The integration of a processor-controlled system in both mobile devices and HMDs, which includes a camera unit to detect the mobile device's position and transmit location information, allowing for detailed notifications to be provided by either the mobile device or HMD based on its position relative to the user's field of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the mobile device provides detailed notifications for all events, then the user receives complete information, but the notification may not be visible when the device is outside the view angle area
Solution Approach 1:
The notification provision is made dynamic based on the mobile device's position relative to the HMD's view angle. The system automatically adjusts between providing detailed notifications (when device is within view angle) and simple notifications (when device is outside view angle), resolving the contradiction between information completeness and visibility.
Solution Approach 2:
Different notification types are applied based on the local condition of device position. Within the view angle area, detailed notifications with full information are provided. Outside the view angle area, simplified notifications are provided. This local differentiation resolves the contradiction by adapting notification quality to spatial context.
2Loss of information
If the HMD provides notifications for all events, then the user receives complete information, but the mobile device's notification function becomes redundant
Solution Approach 1:
The HMD's camera detects the mobile device's position and provides feedback about whether the device is within the view angle area. Based on this feedback, the system determines which device should provide the notification, optimizing the distribution of notification responsibilities and reducing unnecessary system coordination complexity.
Solution Approach 2:
The mobile device independently determines whether to provide detailed notifications based on its own position relative to the HMD's view angle. When within the view angle, the mobile device serves itself by providing notifications without requiring HMD intervention, simplifying the overall system coordination.
3Reliability
If the mobile device is positioned outside the view angle area, then the user may not see the device screen, but the device should still provide notifications for events
Solution Approach 1:
The notification strategy dynamically adapts to the device's spatial position. When outside the view angle area, the system switches to a reliable notification mode where the HMD provides notifications to ensure delivery, while acknowledging that detailed visual information may be lost. This resolves the contradiction by prioritizing reliable delivery over detailed visibility in this context.

AI summary
The present specification relates to a mobile device, a head mounted display (HMD) paired with the mobile device and a method of controlling therefor, and more particularly, to a method of providing a notification for an occurrence of an event from at least one of the mobile device and the HMD based on a position of the mobile device for the HMD.
