Hand held device with non-permanent led line guides, bookmark, and hand support features

A hand held device with non-permanent LED line guides comprising:

• a container body that contains
• a column of individually controlled LED lights positioned to produce a series of parallel illuminated lines on a writing surface,
• a plurality of individual power controls that selectably control power to the column of individually controlled LED lights,
• a plurality of individual brightness controls that selectably control brightness to the column of individually controlled LED lights,
• a plurality of individual height adjustment controls that selectably control a vertical height position of the column of individually controlled LED lights,
• a column of equally spaced stop guards set into a line guide track of the container body along the column of individually controlled LED lights so as to confine the individual height adjustments to a predetermined spacing,
• a counter configured to receive as input a page number of a document that includes the writing surface,;
• at least two clips disposed on a backside of the container body, and configured to be inserted between pages of the document, and securely fasten the handheld device to the document,
• a first self-leveling foot, a second self-leveling foot, and a third self-leveling foot, each disposed on a supporting surface of said container body, and;
• processing circuitry configured to receive a height measurement output signal, and determine a dynamic height adjustments that is applied to the first self-leveling foot, the second self-leveling foot, and the third self-leveling foot so as to level the container body with respect to the writing surface, and generate an audio alert signal when the level adjustment exceeds a predetermined threshold height,
• a non-transitory storage device that has stored therein an indication of the predetermined height adjustment, said indication of the predetermined height adjustment corresponding to a surface on which the hand held device is mounted;
• and
• an information panel that receives from the processing circuitry an indication of a total height adjustment and provides a visual display of the total height adjustment.
