The prototype device is based on TxtBoard, a situated messaging device that uses the SMS protocol to let members of households broadcast messages home. A tablet device that supports stylus markings, or scribble, in addition to SMS are implemented. The HomeNote prototype is essentially a Toshiba Port´eg´e Tablet PC encased in a wall-mountable frame containing GPRS and SIM cards. This provides each HomeNote with a unique phone number which is used to receive and display text messages sent via mobile phones (in this version users could not send messages out through the device). Local scribbling is also supported using the tablet’s stylus input.
