The development of head-worn computing systems that incorporate advanced optical modules, such as DLP displays and TIR wedges, along with contextual control technologies and sensors, to enable see-through displays, efficient light management, and user-friendly interfaces for presenting micro Doppler signatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If head-worn computing systems use advanced optical modules (DLP displays and TIR wedges) to provide high-resolution see-through displays, then display quality and contextual awareness are improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent combines DLP display technology with TIR wedge optics into an integrated optical module that provides both high-resolution display and see-through capability. The combiner element merges the digital display output with the real-world view, allowing users to see both virtual information and physical environment simultaneously through a single optical path.
Solution Approach 2:
The optical module serves multiple functions: it acts as a display device, a see-through window, and a light management system. The TIR wedge both guides display light to the user's eye and allows environmental light to pass through for see-through capability, eliminating the need for separate components for each function.
2Measurement precision
If head-worn computing systems incorporate advanced optical modules for micro Doppler presentations, then measurement precision and contextual awareness are improved, but device weight and size increase
Solution Approach 1:
The optical components are nested within a compact housing structure. The TIR wedge is positioned within the optical path of the DLP display, and the combiner element is integrated into the optical module assembly, allowing multiple functional elements to occupy overlapping or adjacent spatial volumes rather than requiring separate mounting spaces.

AI summary
Aspects of the present disclosure relate to visual presentation techniques for indicating a location in a head-worn computer using an avatar. A method may include receiving a location indicative of a human presence at a location in an obscured environment, establishing a virtual location marker in a position that is visually available to a person wearing a head-worn computing system, wherein the virtual marker provides an indication of the location in the obscured environment, and generating an avatar as a representation of the human presence and presenting the avatar in a field of view of the head-worn computing system, wherein the presentation of the avatar is positioned in the field of view by visually associating the avatar with the location marker such that the avatar appears to remain at the location marker location, as perceived by a person wearing the head-worn computing system, independent of the head-worn computing system's viewing angle.
