(I’m a big fan of dotted or dashed lines, it’s a great visual trick for representing hidden things. Glad to see that Mike is taking up this language, we should develop it further!)

Here’s the description of the talk in full, the slides are available from slideshare and at Mike’s weblog:

Things have long had identifying marks, from silversmiths’ hallmarks to barcodes, but mating machine-readable identification with pervasive networking greatly increases the value of the marks.

For example, when a machine-readable identification method such as an RFID or a high-density visual code is combined with the wireless networking of a mobile phone, a new way of interacting with everyday objects is created. Once you have the capability uniquely identify anything immediately, you can attach meta information to it. Any meta-information. How much is this worth on eBay? Which of my friends has one? Will this go with my Mom’s china? Will it make me sick if I eat it? Was it made by children?

I call this digital representation as accessed through a unique ID, an object’s “information shadow” and I now see them attached to just about everything. Beyond getting meta information, however, lies an even more powerful concept: changing the physical object to a service, for which the thing you’re looking at is but a single instantiation of that agreement. It’s already happened to media, and to car-shared cars and shared bicycles in urban areas.

When this happens, the objects have to change at a fundamental level. They have to be designed differently and they have to be described and discussed differently. The “owner’s” relationship to the object changes. The very idea of ownership changes. The solid object grows a dotted line that is filled-in as-needed, when-needed, and with the features that are needed. This is not the same thing as renting or co-ownership, its anytime/anywhere nature-enabled by the underlying technology makes these new service objects fundamentally new.

Many recent products point in this direction, where objects such as the Amazon Kindle are useless without the service contract, where a Nabaztag/tag is an empty shell waiting for connection to a network full of personal information and social connections, and where NFC phones and RFID peripherals are just the touchpoints between the online and the offline.
