False Non-Match Rate

The False Non-Match Rate or FNMR is another attribute of biometric systems. It refers to the frequency of the system to mistake a signal that matches valid data for one that is invalid, or fits no known pattern.

It differs from False Reject Rate or FRR in that FRR rejects those that come close to the required data, but for whatever reason are still rejected. In contrast, FNMR refers to the rate of rejection for perfect matches. Of course, like most biometric errors, a FNMR as low as possible is desirable.

FNMR type-errors with biometric data are thus much more likely to be encountered, the more precise the data needs to be. Biometric security systems are unlikely to encounter them, as these use multiple methods to determine an individual's identity, and as such are much more likely to have an FRR error. False non matches occur with very precise data such as neural readers detecting specific patterns, or in EMG data.

Japanese Telecomm Predicts Fully Immersive Mainstream VR by 2020
With the expansion rate of Japan's wireless networks in terms of both bandwidth and decreasing cost, coupled with the rate of development of mobile phones into computing platforms in their own right, NTT DoCoMo, Japan's largest mobile phone carrier service believe that this estimate is about right.

Instantaneous Visual Virtual Face
One of the major issues with any virtual form, is facial expression. Traditionally, getting a virtual face to match your physical intent for expression in real-time, was a lost cause. Even for big budget film making, CG overlays had to be constructed frame by frame by hand. Enormously time consuming, ludicrously expensive and completely useless for real-time usage.

The Trazer by Cybex Incorporated. Billed as a virtual reality exercise machine, this $6,495 USD (?3,300) machine tracks an infrared belt worn by the exerciser, and uses changes in the position of that, and senses of increase or decrease in heat rate, to determine how much they are exercising.





At CES 2009, Nvidea unveiled a system of active glasses. Specifically, shutter glasses. The frames alternate polarisation to block light out every second frame, so that each eye gets half the screen update rate of any normal monitor, but will work with a normal output stream just fine.






The dream of a prosthetic limb that touches and feels like a natural limb, is still some ways away. A natural arm or leg processes sensory data at a rate we just do not have the bandwidth to recreate, much less tie into the human nervous system. That said however, significant progress has already been made, and development continues at a rapidly accelerating pace.




Computers are becoming more powerful at an ever-increasing rate, but will they ever become conscious? Artificial intelligence guru Ray Kurzweil thinks so and explains how we will upload our minds and upgrade our bodies to become immortal before the dawn of the 22nd century. In this debate with his critics, including several Discovery Institute Fellows, Kurzweil defends his views and sets the stage for the central question: "What does it mean to be human?"

A Camera that Detects Vital Signs
Originally designed with Olympic events in mind, the INCA camera is a tiny recording device that is also perhaps the first SimStim device in existence. It is capable of interfacing with any body area network to record metadata of temperature, heart rate, breathing, potentially even mood of the subject on screen, and transferring that data directly onto the video file itself, as additional data.
