Attention Informer

May 23, 2006

timeline

Using the model of the Attention Seeker a tool bar appears once swiped to inform a viewer the current point in the duration of the film.

Like the Attention Seeker we made for the experiment, it could discreatly fade in and out at the bottom of the screen, show the duration of the video and indicate through the timeline bar what stage the video is at when you swipe. Because the unique identification number on the card for this application is not required, it would be possible to use cheaper, lower frequency tags and readers, or even use this function inconjunction with others.

This idea also goes hand in hand with, Attention (Re)Starter, where the swipe actually takes you to the beginning of the film. The problem with this idea is the same as the egg timers you get in sauna's, if it has been started before you, you need to wait either until others have left or until its ready to start again anyway. But maybe if the reader could see everyone enter and exit the screening space, it would know if you were alone and know if it were able to restart the video.

Open Call

We're seeking gallery goers in Liverpool to take part in an interactive experiment. The experiment asks nothing more than for you, the audience to give your attention. “Attention Please!” is a video installation with a difference; your attention is important and valuable, pay your attention carefully, and it will be rewarded.

Artist Sara Smith is working with technology partner Kisky Netmedia on this experiment using RFID (Radio Frequency Identification) technology. We're mixing techno tags with vivacious video. We're exploring presence and your effect on the art.

As people, ideas and hot new products compete for our attention through TVs, billboards, and the Internet, do they know if we're really paying attention? What if your attention can be measured? What happens when we pay attention to art? And if we do, will it change or react? Will it know? Does it matter? It does now.

We're looking for individuals and groups to participate in our experiment. Come alone, bring your friends or family; it's fun!

Pay attention at

The Box, FACT, 88 Wood Street, Liverpool, L1 4DQ.

03 & 04 May 2pm – 6pm

Just turn up.
If you want to bring a group before 2pm or only finish work at 6pm and want to come afterwards, contact us and we would be happy to accommodate you!

Looking forward to seeing you!

Writing to tags

April 17, 2006

paul pc and mac

The software that comes with the reader enables you to write 255 blocks of 4 characters to the tags, but what can you do with this after that? Does the tag need interrogating to retrieve this information, or will it send it out whenever it is read?

The reader has to switched (using the software) between read or write mode, each tag has to be added through the inventory reader (same device just in another mode) before it can be written to.
When in write mode (ISO host write) you need to select the tag you are working with input characters you want to write then send to the tag, then the COM interface can read this information when in Scan Mode (HID). This software is only PC format and appear quite complicated but it gives you the basic facilities to use the tags.

For our experiment, we are talking specifically about attention and audience participation-is it even important that we can write to the tag? I feel its important that we investigate this process as its something that makes the tags unique other than their ID number. We have been talking about the notion of rewarding our visitor's by giving them their tag (transponder) with their name written on it.
We could add another terminal to the set-up and use a PC with the COM interface software to simply write to the tag, but this would involve either using our registration reader or purchasing a fifth reader that we simply don't have budget for.
Or if we could find someone to write a Mac application that could be linked with our registration terminal that could write to the tag, but this is a low priority gimmick, only to be added if someone (else) can come up with an easy solution!

The shopping list

 RFID components

So what have we bought?
We have purchased the cheaper of the readers available that are high frequency (13.56MHz) rather than ultra high frequency (915MHz), the limitations are a typical reading distance of only 18cm (max distance I have found was 1.2m), but the UHF readers require external antennas which increases the range of the reader dramatically. The FEIG reader can be supplied as either RS232 connection (with separate power supply) or USB – we chose USB version.
The tags come in all shapes and sizes that signifies the amount of data the can be written to the tags. Remember when buying the tags to make sure they are the same frequency as the readers other wise they just won't work (thanks Scott, from BuyRFID!!!!).

I got quotes from BuyRFID (US) and RFID Components Ltd (UK) both of which were very helpful, supportive and competitive quotes.

3 FEIG PR101 USB Proximity Reader
250 13.56MHz Vicinity Card Transponders (or we could have purchased White Film Tags TIT – WFL 13.56MHz, from BuyRFID)
