The burning tablecloth

• Imagine that the table is set and dinner is ready. It’s time to sit down and share the moment. That is what we do also in terms of sharing a one time pattern change in the tablecloth, and in terms of sharing each others’ mobile phone activity. Incoming phone calls and messages are not notified by the phones themselves, but through a burned out pattern in the tablecloth, in between our plates. The Burning Tablecloth serves as a design example of the design technique for irreversible patterns, expressing colour and structure-changes in a knitted textile. The Burning Tablecloth changes colour and structure according to mobile phone signals (calls and text messages) with burned out patterns and acts as a medium for raising questions about interactive tactile and visual expressions in textiles. The project is a design example of research into three fields, knitted circuits, textile patterns and peoples’ relation to computational technology. The tablecloth is knitted with cotton yarns and a heating wire in a Stoll flatbed knitting machine. The pattern that appears when using the tablecloth is built up as squares with the potential of becoming chess-patterned over the whole tablecloth surface. The table-cloth is connected to a microcontroller and various electronic components. The heating wire knitted in the table-cloth is the active material; when heated it is able to change the colour and structure of the table-cloth. The burning tablecloth reacts to mobile phone signals by getting warm so that colour and eventually structure changes is appearing in the tablecloth. The experiment demonstrates a design example where visual and tactile interactive properties are expressed in a tablecloth by mobile phone signals. Combined in a material structure, textile circuits are controlled by external stimuli adding an aesthetical value to the textile expression. With a foundation of experienced knowledge from latter experiments, the tablecloth shows an example developed by the design technique for irreversible patterns. The Burning Tablecloth also demonstrates how information can be expressed in an esthetical way through textiles, acting as an interactive colour and structure changing ambient textile display.
