Focus Blur

Focus blur is a fullscreen effect intended to replicate the visual acuity of a camera in the virtual environment. It is also known as depth blur, depth of field, or lens blur. It creates a focus-field, usually by means very similar to an alpha blend of the final image in the video buffer, which renders only objects at a given depth as solid. The others get rendered increasingly fuzzily as they move away from the target depth.

Cameras Without Lenses
It sounds odd to think of cameras without lenses to focus the light, because cameras have continually been created with intent to replicate the eye, and the eye has a lens. Without a lens, how do you focus light? Well you don't, but that's ok, because you don't have to.

Attention is what makes Sensory Data Stand Out
The title above should come as no surprise to most people. However, we now have empirical scientific evidence to back this up. When you concentrate your attention or focus on a particular channel of sensory input, it comes in clear and sharp, regardless of the background information. The study focuses on the sense of sight, but what applies there, applies to all.

Podcast: Woody Norris: Inventing the next amazing thing: Directional Sound
The talk is primarily focussed on demonstrating his new invention 'hypersonic sound'. It is essentially a way to precisely focus sound, or as the inventor puts it "put sound where you want to." This has obvious implications for 3D sound effects in virtual reality and channeled sound cones in augmented reality.
