Optical See-Through System
An optical see through system or OST, is a type of augmented reality display in which the virtual display unit is transparent, letting in an unfiltered physical world. This type of display offers a zero-latency approach over natural sight. The downside however, is that there is very little time to properly calculate the placement of virtual effects onto the physical.

An automated calibration method, designed for optical microscopes, may find a home in head mounted display units and heads-up augmented reality systems.
Optogenetics as a field of study, is only a few years old but already a means has been found to make use of it in living brains. Light-detecting proteins combined with gene therapy and an optical neuroprosthetic with a BrainGate style 3D array allow true two-way communication between the brain and a computer system.
Virtual sight devices, sometimes termed virtual light, are a class of display system which is a mix of AR, prosthetics, and VR. They have no actual display units as such, and completely bypass the human eye. Instead, they tap into the optical nerve directly, and deliver processed information to the neurons heading into the brain.
A study conducted to understand how flies and bees can navigate so precisely using just natural sunlight, has interesting implications for machine vision, and adding additional sense-based navigation systems to UAVs and UGVs without adding the weight or cost of any extra hardware.
This still from Chrysalis shows a very different method of locking and unlocking your front door than we are used to. There is no key and no key hole. Instead, what there is is a retinal scanner embedded in the door level with the average head. Peer in and if it recognises you, it unlocks. If not, there is nothing to pick.
Zebrafish are handy little critters, as far as neuroscience goes. These tiny, mostly transparent little fish have brains that whilst greatly simplified, have a structure remarkably similar in basic form, to our own. Add in that aforementioned near-transparency, and it becomes possible under the correct lighting conditions, to literally see right into their brains, to the point where you can practically watch as a thought takes place.
Unlike in the peripheral nervous system, where cells are often unable to distinguish which branching pathway an electrical system is travelling from, the central nervous system makes use of sophisticated internal networks not too dissimilar from an IP record, to differentiate between nervous pathways.
This book is very much a holistic first-timer?s guide to creating a hideously complex system ? a full virtual reality. The book describes a VR system as ?a system that provides a synthetic experience for its user(s)?, a definition which could not possibly be any broader.
One person?s take on creating an inventory system that emulates reality.
Industry news, originally posted 02-02-2004, deemed too important to allow to fade. Tired of battling with wardrobe accessories in crampt changing rooms? Fed up of trying oh-so-carefully not to damage items whilst your body does its best to get in the way, and the stall is falling apart around you? VR may have a solution, in the form of a system developed by Toshiba. The company is developing a 3D, realtime system uses video cameras to create a virtual copy of your body on a screen, and not only moves with you, just as a mirror would, but also tries on clothes, without you having to. The system is still at an early stage, but it could in use in stores within three years.
