“…Similar to the design of Olson et al [2011] and the Oculus Rift, this assembly holds a pair of aspheric magnifying lenses (ElectroOptix, Inc. AHM-5). The lenses are separated from the top LCD by slightly less than their 5.1 cm focal length in order to synthesize a magnified, erect virtual image appearing near "optical infinity".…”

Conventional DisplayCascaded Display Factorizations Cascaded LCD Prototype Layer 1 Layer 2 Figure 1: A pair of off-the-shelf LCDs were modified to create a cascaded display: placed in direct contact with a fixed lateral offset. In comparison to any single LCD used in their construction, cascaded displays can quadruple spatial resolution by presenting attenuation layer patterns that are optimized, in real time, using non-negative matrix factorization. (Motorsport image courtesy Aurélien Vialatte.) AbstractWe demonstrate that layered spatial light modulators (SLMs), subject to fixed lateral displacements and refreshed at staggered intervals, can synthesize images with greater spatiotemporal resolution than that afforded by any single SLM used in their construction. Dubbed cascaded displays, such architectures enable superresolution flat panel displays (e.g., using thin stacks of liquid crystal displays (LCDs)) and digital projectors (e.g., relaying the image of one SLM onto another). We introduce a comprehensive optimization framework, leveraging non-negative matrix and tensor factorization, that decomposes target images and videos into multi-layered, time-multiplexed attenuation patterns-offering a flexible trade-off between apparent image brightness, spatial resolution, and refresh rate. Through this analysis, we develop a real-time dual-layer factorization method that quadruples spatial resolution and doubles refresh rate. Compared to prior superresolution displays, cascaded displays place fewer restrictions on the hardware, offering thin designs without moving parts or the necessity of temporal multiplexing. Furthermore, cascaded displays are the first use of multi-layer displays to increase apparent temporal resolution. We validate these concepts using two custom-built prototypes: a dual-layer LCD and a dual-modulation liquid crystal on silicon (LCoS) projector, with the former emphasizing head-mounted display (HMD) applications.

“…Failed attempts at VR systems by Nintendo (Virtual Boy) and Sega (Sega VR) in the 1990s and a further lack of development into the 2000s had many of its critics arguing the technology was "dead" [3]. However, as noted by Olson [4] the video games industry has driven advances in graphics cards that are able to handle increasingly sophisticated 3D constructed environments. Furthermore, simultaneous developments in smartphones and HMDs have made VR an accessible commodity for consumers.…”

With the increasing power of mobile CPUs and GPUs, it is becoming tractable to integrate all the components of an interactive, immersive virtual reality system onto a small mobile device. We present a demonstration of a head-mounted display system integrated onto an iPhone-based platform. In building this demonstration we tackled two main problems. First, how to integrate the userinterface, utilizing the phone itself as an unseen touch interface. Second, how to integrate multiple inertial measuring units to facilitate user interaction. The resulting system indicates the practicality of mobile virtual reality systems based on smartphones.
