# What is “RFIS” tag

I read somewhere about "RFIS" tag. I know what is "RFID" but does something called "RFIS" exist? I tried to search but all suggestions are RFID related. Would be nice if you have any clue share it please.

It could be just a mistake, so just simply it should have been RFID! or maybe this is something very new and no one knows about it!

This is a part of title:

"a body area network composed of compass and tilt sensors and RFIS tags"

-

Almost certainly a typo. Note that the s key is right next to the d.

But it may also refer to the new "Radio Frequency ISentification" technology, of course :-).

edit after your question update
The abstract talks about "intelligent guide to help blind people to solve puzzles". It's easily imaginable that RFID could be used to identify the puzzle pieces.

 Now that you pointed out D and S keys are next to eachother it makes much more sense! Beleive it, this is part of title of on an project fo a PHD position so I was like this should be some serious new technology or something! – Sean87 Jul 25 '12 at 8:31 I had no idea we had the tag. Cool stuff. – drxzcl Jul 25 '12 at 9:07 @drxzcl - I didn't know it either, but somebody else used it in a recent question or answer. We learn every day! :-) – stevenvh Jul 25 '12 at 9:11 aaa so you found it :D – Sean87 Jul 25 '12 at 9:20 @Sean87 - Ah, it wasn't even a challenge ;-) – stevenvh Jul 25 '12 at 9:24

According to Acronyms Dictionary, it can be as well:

RFIS    Remote Frequency Indicator Selector
RFIS    RWS/Fire-Control Interface Software
RFIS    Radio Frequency Interface Subsystem/System


I have a hard time believing that someone could make a typo in PhD project title.

 Sean hadn't told about the PhD yet when I posted, and it looks indeed hard to believe to have this kind of error in a project title, but there's still the reference to the "tag", so it doesn't look impossible to me. – stevenvh Jul 25 '12 at 8:57 @stevenvh, true :) – Andrejs Cainikovs Jul 25 '12 at 9:01 @stevenvh Sorry I was excited while posting my question, I gave more info in my question update maybe it can give more clue what they are talking about? – Sean87 Jul 25 '12 at 9:04 @AndrejsCainikovs Thanks for the dictionary!! – Sean87 Jul 25 '12 at 9:05 @Sean87 - There's also acronymfinder. – stevenvh Jul 25 '12 at 11:56

There is every indication that it is a "typo" as others have suggested.

The original text is as below, in relation to a 'pervasive systems' research incentive at a European university. Anyone else may find it in the same way that I did :-) :

• Have you ever tried to solve a puzzle blind folded? As strange as it may sound, it can be done if somebody next to you can act as your eyes; sees what you need to see and think for you. This is exactly what this project aims at doing but instead of having a person next to you, a body area network composed of compass and tilt sensors and RFIS tags will help you.

The idea is through grouping, object identification, and recognizing interaction between hand and puzzle pieces to build an intelligent guide to help blind people to solve puzzles. Each puzzle piece needs to be identified, its association with other pieces needs to be recognized and guidance and feed back (in forms of voice or hepatic feedback ) should be given to the player while choosing puzzle pieces and trying to put the pieces in the right place with right orientation.

The term has no special meaning in "pervasive systems" .

The term is used in this document in answer to Q2.10

1. Pervasive computing using RFIS, multi-touch.

but it seems more likely to be a typo here than a new acronym.
