Head-Mounted Field-of-View Capture With Laser Focal-Point Marking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During service or repair work on machinery or industrial equipment, there is a need for remote assistance where the on-site personnel require guidance from a distant expert who cannot visually see the work site.
Innovation Solution
A system is developed to optically capture and electronically transmit a person's field of vision with a variably determinable focal point to a remote receiving station, using an image recording unit, focal point generation unit, and image transmission unit, potentially integrated with a carrier element like a headband or helmet, and including sound recording and playback for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a mobile phone with camera or glasses with built-in camera is used to capture and transmit the field of view, then the remote person can see the work site, but the remote person cannot identify the specific focal point or area of interest that the on-site person is looking at
Solution Approach 1:
A laser pointer is introduced as an intermediary device to mark the focal point. The laser pointer projects a visible dot onto the work site, serving as a visual mediator that indicates exactly where the on-site person is looking or pointing. This allows the remote person to immediately identify the area of interest without needing to interpret the on-site person's gestures or speech, thus transmitting focal point information effectively.
Solution Approach 2:
The laser pointer produces a brightly colored dot (typically red, green, or blue) that stands out against the background of the work site. This color contrast makes the focal point highly visible and easily distinguishable in the transmitted video feed, enabling the remote person to quickly identify the specific area being referenced without additional verbal explanation.
2Adaptability or versatility
If the image recording unit and focal point generation unit are integrated into a single detachable unit, then the system becomes more compact and versatile, but the ease of operation may be reduced due to assembly and disassembly requirements
Solution Approach 1:
The system is divided into separate functional modules: the image recording unit (camera), the focal point generation unit (laser pointer), and the carrier element (headband or glasses). These modular components can be detached and reattached, allowing the system to be adapted to different configurations and use cases. The segmentation enables flexibility in how the components are assembled and used, catering to different user needs and scenarios.
Solution Approach 2:
The carrier element is designed to accommodate both the image recording unit and the focal point generation unit, making it a universal platform that can support multiple functions. The same carrier can hold different camera devices or laser pointer types, allowing the system to be versatile and adaptable to various requirements while maintaining a consistent base structure.

AI summary
System for optically capturing and instantaneously electronically forwarding at least a portion of the field of vision of a person together with a variably determinable focal point of the person in question, optically displayed in the person's field of vision, to a spatially remote receiving and playback station, with an image recording unit and a focal point generation unit, which can be fixed to the person's head by means of a carrier element, and with an image transmission unit for transmitting at least a portion of the field of vision together with the optically displayed focal point to the spatially remote receiving and playback station.
