World’s thinnest hologram paves path to new 3D world – RMIT University

Now a pioneering team led by RMIT University’s Distinguished Professor Min Gu has designed a nano-hologram that is simple to make, can be seen without 3D goggles and is 1000 times thinner than a human hair.

“Conventional computer-generated holograms are too big for electronic devices but our ultrathin hologram overcomes those size barriers,” Gu said.

“Our nano-hologram is also fabricated using a simple and fast direct laser writing system, which makes our design suitable for large-scale uses and mass manufacture.

“Integrating holography into everyday electronics would make screen size irrelevant – a pop-up 3D hologram can display a wealth of data that doesn’t neatly fit on a phone or watch.

Dr Zengji Yue, who co-authored the paper with BIT’s Gaolei Xue, said: “The next stage for this research will be developing a rigid thin film that could be laid onto an LCD screen to enable 3D holographic display.

“This involves shrinking our nano-hologram’s pixel size, making it at least 10 times smaller.

“But beyond that, we are looking to create flexible and elastic thin films that could be used on a whole range of surfaces, opening up the horizons of holographic applications.”

haptics for VR walls and other objects [CHI17 fullpaper]
← SIC on EMS [UIST16 contest hardware]
Ad Infinitum: a parasite [ScienceGallery’17] →

In this project, we explored how to add haptics to walls and other heavy objects in virtual reality. Our main idea is to prevent the user’s hands from penetrating virtual objects by means of electrical muscle stimulation (EMS). Figure 1a shows an example. As the shown user lifts a virtual cube, our system lets the user feel the weight and resistance of the cube. The heavier the cube and the harder the user presses the cube, the stronger a counterforce the system generates. Figure 1b illustrates how our system implements the physicality of the cube, i.e., by actuating the user’s opposing muscles with EMS.

Projection mapping on a moving surface

This research aims at overcoming this limitation and realizes dynamic projection mapping in which dynamically-changing real-world and virtual visual information are completely merged in the level of human visual perception. This high-speed dynamic projection mapping requires a high-speed projector enabling high-frame-rate and low-latency projection. In order to meet this demand, we have developed a high-speed projector “DynaFlash” that can project 8-bit images up to 1,000fps with 3ms delay.In particular, as a challenging target for the dynamic projection mapping, we focus on a non-rigid surface. Sensing of non-rigid surface deformation is difficult to be achieved at high speed because it has high degrees-of-freedom and involves self-occlusions as well as external occlusions. Our newly proposed method overcomes this limitation. Our method can obtain the deformation robustly at 1,000 fps by using an originally proposed marker “Deformable Dot Cluster Marker”, even when the target causes large deformation and occlusions.

PrintScreen: print touch screens on anything, including paper

PrintScreen is an enabling technology for digital fabrication of customized flexible displays using thin-film electroluminescence (TFEL). It enables inexpensive and rapid fabrication of highly customized displays in low volume, in a simple lab environment, print shop or even at home. We show how to print ultra-thin (120 um) segmented and passive matrix displays in greyscale or multi-color on a variety of deformable and rigid substrate materials

Sharp Develops Free-Form Display, Enables Vastly Greater Design Freedom for Displays

Sharp announces the development of the Free-Form Display, a device that can be shaped to meet a wide range of user needs thanks to the incorporation of IGZO technology and proprietary circuit design methods. Conventional displays are rectangular because they require a minimal width for the bezel in order to accommodate the drive circuit, called the gate driver, around the perimeter of the screen’s display area. With the Free-Form Display, the gate driver’s function is dispersed throughout the pixels on the display area. This allows the bezel to be shrunk considerably, and it gives the freedom to design the LCD to match whatever shape the display area of the screen needs to be.

Flexibile, high definition CAAC-OS displays from SEL curve around bezels

As one way to utilize this flexibility, SEL have produced side-roll and top-roll OLED displays, with the display curving over the edge where a bezel would usually be.The prototypes on show were a 3.4-inch 960×540 pixel display with a resolution of 326 ppi, and a 5.4-inch 960×1280 pixel display with a 302 ppi resolution. They still provide the high color reproduction characteristic of OLED displays.

Researchers find a way to make glass that’s anti-fogging, self-cleaning and free of glare

Through a process involving thin layers of material deposited on a surface and then selectively etched away, the MIT team produced a surface covered with tiny cones, each five times taller than their width. This pattern prevents reflections, while at the same time repelling water from the surface

Edge blending software

Edge Blending software allows you to connect multiple projectors so that they overlap and then set them up so that the output of each beamer is aligned and the brightness of the overlapping area is corrected so that the image looks seamless.

Quite a few of these packages only allow the output to be corrected in an openGL / DirectX environment.

Below is an overview of Edge Blenders that also allow the whole windows desktop to be projected over all the beamers.

Some of these can auto set up using a webcam.
