False Accept Rate

The False Accept Rate or FAR (similar to the False Match Rate or FMR) is a measurement of the accuracy of biometric data being recorded by a given system. By its very nature biometric data is organic in origin, and organic data is subject to considerable variance between both individuals and sessions.

With both interface and security-based biometrics, FAR is referred to as the accuracy of the data being checked. A high FAR indicates that there is a wide margin for error in the data being checked, such that whilst it is possible to pick up all variations an individual might use – differences in their gait for example – opening the net that far may incorrectly identify other individuals as being that person.

On the other hand, narrowing the margin for error too much, will effectively lock out an authorised person who maybe has a sore ankle that day, and is walking slightly differently.

With interface biometrics, the situation is a little different. Here biometrics are usually neural codes or EMG readings of muscle potential. A high false accept rate here means that there is a high potential that the neural code will be misread, and an action other than what was intended, triggered. As an extreme example, the person meant to raise their hand with the beer glass in it, but the system falsely interpreted that as another command instead, opening the hand so the beer glass fell to the floor and smashed.

The difference between FMR and FAR is subtle, but important. Whilst a false accept is 'not quite right, but close enough', a false match means exactly that. One command has been misconstrued as another command completely.

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.

Book Quotes: Refusing to See - AI Rights
Idoru is, essentially, one long piece on the struggle to understand the quest for robot rights ? or in this case, the rights of an AI itself, from an outsider?s perspective; from the perspective of one who refuses to accept the AI as other than a tool, despite all evidence to the contrary.

Animatrix: A Detective Story
A Detective story is unique in the Animatrix set, because it deliberately uses a different colour palette for the world. All characters seem to get on with the changed palette and treat it as normal, a grainy, yellowing film noir look. If that palette and those colours are all you have ever known, you are going to accept them as real.

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?"
