ABSTRACT:
A reading pacer and reading speed indicator including a transparent tube having a viscous fluid therein and a pace-indicating member of differing density from that of the fluid, such as a steel ball, for association with the lateral edge of reading matter in order to be visible in the peripheral vision of a reader and to pace or indicate a reading rate in accordance with the slope or angle thereof with respect to the vertical. A curved section of the tube carries both indicia and an indicator member for preselecting or determining the slope of the pacer tube.
Preferably, the pacer unit includes means for attaching or mounting the unit directly upon the surface of the page and includes means for quickly re-setting the pace-indicating member into association with the first portion of the reading matter. The pacer unit may be invertible for reset or may include mobile means such as a magnet for re-setting a ferrous pace-indicating member.
