Solution Overview
Problem
Current head-mountable devices lack the capability to provide comprehensive environmental awareness and user interaction through multiple views, limiting their functionality in virtual and augmented reality applications.
Innovation Solution
Integration of multiple cameras and sensors into a head-mountable device that captures and processes multiple views of the environment, allowing for video passthrough, object detection, and user interaction, with adjustable camera positions and sensor arrays for enhanced field of view and detection capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cameras are integrated into the head-mountable device to capture multiple views, then environmental awareness and user interaction capability are improved, but device complexity and weight increase
Solution Approach 1:
The device divides the camera system into multiple independent camera modules positioned at different locations (front, rear, left, right sides). Each camera captures a specific view, and the system segments the overall field of view into multiple discrete camera feeds that are processed independently before being combined or selectively displayed.
Solution Approach 2:
The system transitions from a single-view (2D display of one camera feed) to a multi-view spatial arrangement by positioning cameras around the device in three-dimensional space. This allows capture of environmental data from multiple spatial dimensions simultaneously, creating a comprehensive spatial awareness capability.
2Adaptability or versatility
If multiple cameras and sensors are integrated to provide comprehensive environmental awareness, then functionality in virtual and augmented reality applications is improved, but weight of the device increases
Solution Approach 1:
The camera system is designed to serve multiple functions simultaneously: capturing environmental video for passthrough display, detecting objects for interaction, providing spatial awareness for navigation, and enabling various VR/AR applications. This multi-functionality reduces the need for separate specialized components.
Solution Approach 2:
Multiple camera modules and sensor arrays are integrated and combined into a single unified head-mountable device structure. The system merges data from all cameras and sensors through centralized processing to create comprehensive environmental awareness, reducing overall system weight compared to having separate devices for each function.
3Difficulty of detecting and measuring
If camera positions are made adjustable to enhance field of view, then detection capability is improved, but device complexity increases
Solution Approach 1:
The camera positioning system transitions from fixed to adjustable/dynamic positions. Cameras can be moved or repositioned to optimize field of view and detection capabilities based on user needs and environmental conditions, allowing the system to adapt its sensing geometry dynamically.

AI summary
A head-mountable device can have multiple cameras, which may be used to generate graphical content, provide a video passthrough of the environment, and/or sense objects, people, or events in the environment. The cameras of the head-mountable device can capture views that are output to a display. Other sensors and/or detectors can detect the presence or motion of objects and/or events in an environment of the user and provide outputs that call the user's attention to such objects and/or events. The outputs can include notifications, selectable features of a visual display output, and/or a view that includes the objects and/or events. The cameras can be integrated in a way that provides a low profile, such as by incorporation with other features of the head-mountable device.
