Abstract
A time-passage indicator device can comprise a housing, a plurality of light elements located inside the housing, a window comprising an inner and an outer surface, and a processor that controls the plurality of light elements. Some devices also contain a touch sensor, and the processor controls the light elements based upon signals from the touch sensor. The window can be attached to the housing and diffuses or scatters the light from the plurality of light elements. The light elements can emit light through the window forming an illuminated region viewable by a user. The processor can control the light elements such that the illuminated region changes to indicate the passage of time. The illuminated region can be viewable from all angles between 10 degrees and 90 degrees, where the angle of 90 degrees corresponds to a normal viewing angle.
