The application/hack that we built is something that we are calling “shifd”, which is pronounced “shift”, not “shifty”…though Nick is kind of a shifty guy… Anyway, we wanted to build something that allows you to shift between your desktop, mobile, tv, car, etc experiences in a more seamless way…

Hack Day was a tremendous experience…I won’t reiterate everything here…we did a few interviews on our Hack Day experience with the great folks at BBC Backstage and Yahoo! Developers Network (part 1, part 2). Below is a video that explains our hack (we shot it right after we got back from Hack Day and hadn’t slept in three days, so be warned!) and some links to some of the tools that we used in our application.

Why RFID??
RFID may or may not be the proper technology to use here. Of course Bluetooth or NFC achieves the same thing that we were trying to achieve with RFID – detecting presence. We’ve gotten a lot of “Why the hell did you use RFID for this? You should have used Bluetooth!”comments. Sure, Bluetooth is much more prevalent and no one has an RFID reader hooked up to their laptop/desktop… but remember that this was all about a “hack” that we had to throw together in 24 hours. Here’s a few reasons why we ended up using RFID:

1. It was very easy to implement a quick “hack” that would detect “presence” for us using the RFID tags/readers that we took along with us to Hack Day. We only had 24 hours to build this thing and I didn’t want to mess around with a Bluetooth library that I’ve never used before. RFID was easy and that’s why we used it.
2. A lot of the developers at Hack Day that tried to use Bluetooth in their hacks had to resort to “wired” solutions because of all of the noise/interference in the room at Alexandra Palace. Everyone that got up on stage to present their Bluetooth hack said something along the lines of “well, we tried to use bluetooth but couldn’t get it working in this room…”. I’m glad we ended up using RFID…..

What’s Next?
We are working on putting out a version of shifd.com in the next few months. We’re going to launch the web and mobile pieces first and then will layer in the “presence” in a later release (using Bluetooth, etc).
