It’s like homemade cookies. You can make them yourself, provided you have the ingredients, some kitchen utensils, a bowl and an oven.Photo by Fabio Bruna, http://flickr.com/photos/_fabio/104792456/. CC-BY 2.0.
This is a broad term, and there are many different terms that all more or less mean the same thing. Such terms are Pervasive Computing, Ambient Intelligence, Physical Computing, Everyware and the Internet of Things.
For our purposes today, Ubiquitous Computing is – again quoting Wikipedia – about a “post-desktop model of human-computer interaction”. This means it’s not about our laptops and external monitors, but about smart devices that we wouldn’t necessarily recognize as being a computer.

In the next half-hour or so I’ll take you through some amazing projects. We’ll talk about tools and products you can use yourself and where to get some inspiration. But first, let’s talk about the spirit of Homemade and this new world ubicomp may bring.Photo by Tobias Toft, http://flickr.com/photos/tobiastoft/3127970010/. CC-BY 2.0.

In a way, Homemade Ubicomp is a science kit for all of us. We can play with it, learn from it, experiment and innovate.Photo by Jeff Keyzer, http://flickr.com/photos/mightyohm/2729474646/. CC-BY 2.0.
The advances of Ubiquitous Computing have the potential of creating a whole new world. There are many upsides to this world, but also a few downsides.Photo by Dan Foy, http://flickr.com/photos/orangeacid/459207903/. CC-BY 2.0.
It’s not hard to imagine that in the near future, your new pair of jeans will have an embedded RFID tag that can be used to not only hamper theft, but also recognize you as a customer.
Ubiquitous Computing is about more than just RFID of course. Essentially, it’s about all data that can be captured through sensors: whether a door is open or closed, the temperature in a room, noise levels and so on.Photo by myuibe, http://flickr.com/photos/myuibe/2439798709/. CC-BY 2.0.
Should the jeans store tell you about the tag in your jeans? How easy should it be to find, so that you can destroy it?
Why are there RFID chips in our passports in the first place? They’ve proven to be susceptible to eavesdropping and straight copying. Sure, usually they’re encrypted, but how strong is that encryption? RFID transport cards have been completely broken.
Wouldn’t a non-wireless chip have been better? Or did the RFID companies win the lobbying game?Photo by Lali Masriera, http://flickr.com/photos/visualpanic/3209209460/. CC-BY 2.0.

Used because Mediamatic is awesome and needs to be promoted as much as possible.
The bottle contains an Arduino board which is a programmable micro-processor that you can hook up to all kinds of out- and inputs; an accelerometer to detect when you turn the bottle upside down; an LCD screen to display the message; an LED to make it glow and a module for radio communication.
There’s another Arduino with radio transmitter that sends emails to the bottle. Unfortunately they never got actual integration with email working, so this is still a prototype.
Let’s see a video of how it’s used.

The scale itself is driven by an engine, which shows you the balance between the food on the left side, and the number of tries on the right.Project page and video: http://dkds.ciid.dk/py/tangible-user-interface/projects/meet-the-food-you-eat/

We used a bunch of laptops, RFID readers, various electronic things, and construction materials. Nothing ridiculously expensive, nor something that takes months to create.Photo by Daria Perevezentsev, http://www.mediamatic.net/page/52662/en.

What you need to build this? An old couch, car massage chairs, two RFID readers and a laptop. Perhaps a car battery and LED displays to show massage credit. Not very high tech, but pretty awesome!

Requirements: two small stage elevators (not exactly home made, but hey). Computer, two RFID readers, some mechanics and Arduino to control the elevators via computer. And the controls are nothing fancy: the Arduino drives an engine that pushes the up or down buttons. There’s an optical scanner trick that measures how high the elevator has gone so it stops in time.iKWiN: http://www.mediamatic.net/page/52953/enPhoto by Mathias Forbach, http://www.mediamatic.net/page/54630/en.

Unfortunately the hardware kept breaking, so in total we only played with it for about 15 minutes. That said, those were 15 very cool minutes.
Requirements: large bird, Arduino with accelerometer and RFID reader, laptop for communicating with the bird and playing the sounds. Less easy to get: wireless camera and processing infrastructure.Vbird: http://www.mediamatic.net/page/52865/en

Violet is a French company that sells the Mir:ror, which Brian used, as well as the Nabaztag. This is rabbit connected directly to the internet via Wi-Fi. It participates in Violet’s social network, so you can add friends, get news updates and so on. It has an RFID reader so you can trigger actions, just like the Mir:ror.
You can hack the Nabaztag so it doesn’t point at Violet’s servers but your own. This allows you to circumvent Violet’s social network, which, to be frank, kind of sucks.
The Mir:ror allows you to launch applications on your own computer, and do calls to web servers. This latter is really cool, because it makes it very easy to program web responses to a tag being read in your room. For example, logging in to Dopplr ;-)
A Nabaztag costs € 145, or about 1600 SEK. A Mir:ror is € 49 or 550 SEK. This is excluding shipping.

I think that, fundamentally, Touchatag is an engineering company, whereas Violet has more design sensibilities (in fact, Touchatag is an Alcatel-Lucent venture). This is reflected in the devices themselves. You can set up server interactions with Touchatag, but it’s a very complicated engineering process rather than a simple server call. The Mir:ror is also prettier, it beeps and blinks. It also reads more RFID tags than Touchatag.
During PICNIC, we’ve successfully used the Touchatag readers to drive several projects, although we circumvented the required Touchatag software and interacted with the reader directly.
The Touchatag costs € 30, or 330 SEK.Photo by Mark Wubben, http://flickr.com/photos/novemberborn/2958316938/. CC-BY 2.0.
The design of the Arduino is open source, which is a really cool approach. Because of this, there are various variants of the official Arduino.
An Arduino board sells for about 230 SEK.

TinkerKit is a toolkit to rapidly prototype physical computing projects. It is not yet commercially available, but is definitely something to keep an eye on.Photo by tinker_it, http://flickr.com/photos/tinker_it/3257586175/. All rights reserved. I deem this fair use, since I’m essentially marketing their product.
