Abstract
In one embodiment, a tape measure having a tape, housing, and an input, has an OLED strip overlaid on top of the tape. The housing contains a programmable controller and a rolled-up portion of the tape. A specified fraction of the length of the linear target is provided to the controller using the input. The tape may be extracted from the housing to generate an exposed portion of the tape corresponding to the total length of a linear target. The controller receives information indicative of the total length of the linear target. The controller controls the OLED strip to show, i.e., light up along the tape, a fractional portion corresponding to the specified fraction of the linear target.
