Usually, if we're using a regular ruler, we need to use a marker. To do this,
we need to hold a ruler in one hand, then a marker in the other hand and record
the position markers. This measurement method actually has a very certain error,
but also more difficult and cumbersome. The ruler I designed is very convenient.
If you want to measure a length, you can simply pull out the ruler and press where
you want to mark it, and the length can be displayed automatically. This measurement
method avoids certain error, and is convenient and time-saving.
