Prototype 1 - The receipt as a trace

If you had access to someones receipts you would be able to build up a picture of what they do, where they have been and what type of person they are: male/female, old/young.

Receipts act as a trace of where someone has been and what they have been doing.

The more receipts are handled the more the warmth from the hands degrades the thermal paper and leaves a mark of the person's presence. The more the receipt is handled the more evidence it holds of human interaction.

Prototype 1 - Tracing human presence

In order to trace human presence I am going to utilise the properties of thermal paper and manipulate how it visually represents human interaction but on a larger scale.
