Abstract

We present a technology for designing curved display surfaces that can both display information and sense two dimensions of human touch. It is based on 3D printed optics, where the surface of the display is constructed as a bundle of printed light pipes, that direct images from an arbitrary planar image source to the surface of the display. This effectively decouples the display surface and image source, allowing to iterate the design of displays without requiring changes to the complex electronics and optics of the device. In addition, the same optical elements also direct light from the surface of the display back to the image sensor allowing for touch input and proximity detection of a hand relative to the display surface. The resulting technology is effective in designing compact, efficient displays of a small size; this has been applied in the design of interactive animated eyes.

Flexibles

“…Recently, an emerging stream of research investigates how to embed customized interactive elements in 3D-printed objects. This includes adding interactive input and output functionalities in 3D-printed objects through light pipes [56,5], by filling internal pipes with media post-print [39], or via pipes that transmit sound [22]. It has also been shown how to embed interactive structures that can be deformed on-demand [11].…”

“…Objects may be extended by means of conductive plastic [11,20,21] or spray [7]. Moreover, 3D printed pipes are used to redirect in-or output channels in 3D printed objects [26,3,19,10].…”

3-D printable open source dual axis gimbal system for optoelectronic measurements

“…available with CAD models of various parts enables low-cost and relatively easy distributed production by consumers [67] and adopted by scientists [40]. One area that is benefiting from 3-D printing is optics with 3-D printed embedded optical elements and interactive devices [68], curved displays [69], phantoms for whole animal optical imaging [70], spectral system for collagen fluorescence lifetime measurements [71], flexure translation stage for open-source microscopy [72], smart phone microscope adapters [73], a 3-D microscope stage [74] and a large customizable library of mechanical components for optics setups [75]. While open source 3-D printing has seen wide acceptance in biology and optics, it remains conspicuously absent from the semiconductor arena.…”
