The Weight Recorder by Weiche Wu, records the changing weight of a person over a period of time. The device is a mechanical scale with a compass holding a pencil that can draw lines on the tracing paper disk attached to the statistical part. When the user stands on the scale, the compass turns and the pencil draws an arc. The radius of the compass can be adjusted in every usage, so the arcs are drawn concentrically.
