Squeezing More Lens Into Your VR Headset

Gizmodo posted a fantastic article about the VR platform and content being developed at Magic Leap. At the core of what may drive their augmented reality tech is a new kind of lens for scanning and projecting.


Scanning laser projectors sweep one or more beams of luminance-
modulated light in a scan pattern to form an image. The approach
offers a number of advantages in the construction of 3D displays,
compared with conventional matrix-based display technologies
such as LCD, DLP, and OLED. Because the image is formed by a
single scanning pixel rather than an array of pixels, scanning laser
displays can enable significant display miniaturization that is
decoupled from display resolution.

How to Get People to Pay Attention

A machine-generated signal often fails to hold our attention for very long. However, when the signal is someone else’s ongoing creation, engagement can be very high.

In this case, Smart built a video capture mechanism that converts dance moves into a “Do Not Walk” signal.

“Non-invasive” Direct Neural Interface

This tech will lead to some interesting new approaches to controlling things (or people!) over the internet.

Our non-invasive interface, demonstrated originally in August 2013, combines electroencephalography (EEG) for recording brain signals with transcranial magnetic stimulation (TMS) for delivering information to the brain. We illustrate our method using a visuomotor task in which two humans must cooperate through direct brain-to-brain communication to achieve a desired goal in a computer game.

Dutch Defibrillator Drone

There’s an interesting article on Nerdoholic about a flying defibrillator.

The drone tracks emergency mobile calls and uses the GPS to navigate. Once at the scene, an operator, like a paramedic, can watch, talk and instruct those helping the victim by using an on-board camera connected to a control room via a livestream webcam.

Drones can clearly be more than a way to convey the material; they can also project the expertise of an emergency medical professional. There are many imaginable cases where it would be difficult to pre-position materials and expertise that would be required to save a life, from floating devices to blood clotting agents to chemical burn treatments.
