Abstract
Abstract A device for measuring and indicating reading speed in words per minute. The length of any reading assignment up to 9,999 words is set on an input counter on the device. The device is turned on when the reader starts reading the text. At the end of 1 minute, and for every 3 seconds thereafter, light emitting diodes on the device display the reading speed in words per minute. The reader determines his reading speed by observing the reading speed device immediately after reading the passage.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
71 words
A reading rate indicator comprising: elapsed time counting means; input data entry means to allow the entry of a number corresponding to the number of words of text to be read; computation means to operate on the output of the elasped time counter and the input data entry means to compute a number representative of a reading rate in words per minute; display means to display the results of the computation.
