OVERVIEW:
This was a super quick project I did to create a demo system for a 3D camera display. I got to utilize Blender 3D to experiment with some really interesting modeling techniques for the headset itself, along with a brief dip into some optical design for the lense/display system.
DESIGN:
The biggest design parameters of this project were the ergonomics and human factors considerations. The headset was designed to fit anyone comfortably, even while wearing glasses. To account for varying interocular distances between users, the initial design included sliding lenses which could be adjusted using sliders below the headset.
First Design with Adjustable Interocular Distances
The lens/display stack was designed using off the shelf lenses and displays. The headset was designed around the lenses optical center distance, with this distance being fixed. However after testing the first initial design, it was found that the radius of curvature of the lens was great enough that even the interpupillary distance did not need to be adjusted, and instead a fixed lens position could provide the needed optical clarity for users regardless of varying interpupillary distances.
Final Design with Fixed Lens Positions and Improved Ergonomics
The initial design was developed in Solidworks, however due to the desired shape and form of the face plate, Blender 3D was utilized instead to develop complex geometry and curves that would otherwise be too complex for traditional CAD software. The final design featured additional soft padding not shown here, for an extremely comfortable and snug fit.
