A device-free future of ubicomp?

Ubicomp was a lot about interacting with things…

…and we build cheap embedded devices

…to hide sensing and computation everywhere and build infrastructures

Wearable computing was always the antithesis to the appliance-based approach

It only became sexy becauseof the ubiquity of cheap infrastructure and powerful smartphones

… but what comes next??

Device Free vs. Device Bound

So is „device-free“ the (next) future of (ubiquitous) computing?

Thesis Anti-Thesis

The devices shall return….

• Organic Printed Sensor RFID• Will enable printing remote

readable sensors/transducer

• Device-free“ computation by(uncontrolled) Signal Superimposing

• computation on the channel up to 1000x lower energy, faster transmission for 1000 node net

a) device-free is a necessary next step!

• New possibilities

• New constraints

• New thinking

• New knowlege/views:• On RF-Channel

• New Machine-Learning Tools

• New Models

• Complex interactions

“The only thing we know about the future is that it will be different.” (hopefully)

b) device-free != free of devicesc) synthesis of approaches will bring real change
