| The project's goal is to develop unobtrusive, deeply interconnected smart devices - called Smart-Its - that can be attached to everyday items in order to support new functionality, novel interaction patterns and intelligent collaborative behavior. The long-term vision is that devices such as Smart-Its will be as cheap, as unobtrusive and as generic as state-of-the-art smart labels (i.e., radio tags), but in addition they will also be able to communicate with peers, and they will be customizable in their behavior. In order to facilitate a meaningful integration in their environment, Smart-Its are equipped with a broad range of different sensors providing context information. This context information is distributed among collections of Smart-Its and thus permits collaborative evaluation of collected data. Smart-Its will possess perceptive computing capabilities. |

| The
Smart-Its project is based on a philosophy of building and
trying fully functional prototypes, and from day one the partners
have begun to implement hardware/software artefacts that enable
us to study issues in augmentation and networking of everyday
objects. The device development is based on experience from
the partner's previous research, for example conducted in
the Europen project TEA, in TecO's Mediacup work, and in VTT's
SoapBox development. |

| Our
first device prototypes are based on two different microcontroller
platforms, Atmel and PIC. The Atmel platform enables us to
look into Bluetooth integration, while the PIC-based platform
is used in conjunction with RFM communication. The overall
device architecture is modular so that different sensor boards
can be connected to either microcontroller platform. |
| |
| This
Smart-It is based on Atmel's ATmega103L microcontroller with
128 kB of in-system programmable flash memory and only 4 kB
of SRAM. Ericsson's Bluetooth modules allow communication between different devices. |
| |
| This
device is integrates a PIC 16F876 20 MHz for processing, RFM
868 MHz for communication (128kbit/s), on board sensors and
an I2C interface for sensor/actor boards. Power is supplied
by 3V lithium cell |
