A data input device for a computer or other electronic apparatus includes a grid panel having a pattern of grooves in the panel surface and a plurality of sensors along the grooves. The sensors sense the passage of a stylus along the grooves and feed the stylus movement information to electrical circuitry which interprets the movements as data. In an alternate embodiment, the grooves have lower channels in which a lower portion of a stylus guide moves. The stylus guide has a ball-type universal joint on the upper portion to which is connected a fitting for retaining the end of the stylus. An alphabet for use with the present grid panel is also disclosed.
