Abstract

When an image is projected onto a non-planer surface, the resolution is not spatially uniform because projectors are normally designed to display an image with spatially uniform pixel density on a flat surface. We propose to insert a transparent layer between a projector and a non-planar surface and optimize its shape to make the projection pixel density spatially uniform, which can be controlled by non-uniformly refracting a projection light through the transparent layer. We use a multi-material 3D printer to fabricate the transparent layer combined with a non-planar surface. From the result of a projection experiment with the surface, we validate our proposed method.

Virtual rear projection: do shadows matter?
CHI EA '05: CHI '05 Extended Abstracts on Human Factors in Computing Systems

Rear projection of large-scale upright displays is often preferred over front projection because of the lack of shadows that occlude the projected image. However, rear projection is not always a feasible option for space and cost reasons. Recent ...
Shape-controlled microlens arrays fabricated by diffuser lithography

In this study, we used diffuser lithography to fabricate microlens arrays with the height smaller or larger than the radius of curvature of microlenses. The experimental results showed that the fill factor of the duplicated microlens arrays can be ...
Silicon micro-cantilever chemical sensors fabricated in double-layer silicon-on-insulator (SOI) wafer

Micro-cantilever piezoresistive sensors are optimally designed and fabricated in a double-layer silicon-on-insulator (SOI) wafer. The sensor geometry is optimized by placing the sensing piezoresistor at the cantilever root region to increase effective ...
