Visual Math

Every once in a while, I'll see a retweet of this image explaining the discrete Fourier transform (DFT) by Stuart Riffle: Though fully understanding this equation requires the requisite mathematical background to precisely decompose, it's visually apparent to observe how coloring the components might help form an intuitive understanding of…

Explained: Inside-Out Tracking

A primary contributor to a sense of active presence in virtual reality is low-latency, high-accuracy six-degree-of-freedom head tracking (6DoF). Similarly for augmented reality, tracking is a major piece in creating augmentations that are believably anchored in an environment. Driven by the observation that the experience is the product of mixed…

HMD Personalization

The third generation of virtual reality is imminent with early-2016 consumer product launches of both Rift and Vive. This generation's stack of tech (rendering, optics, display, tracking) is about to hit a sweet spot between affordability and immersion, helping our brain blur the boundary between simulation and reality. Some of…

Lens Blur and Beyond

In mid-2014, Google released a new camera app with a compelling computational photography feature for simulating a shallow depth of field. Traditionally, capturing this effect requires a traditonally thick, multi-element lens with a wide aperture. High-end smartphones like the iPhone 5s or Nexus 5 have demonstratively shown better results in…
