Arrows should be used when representing movement, direction, extension, progress, etc. When its purpose in print is not any of those, it is very unlikely to remain as arrow in the tactile. A couple of typical examples that arrows in the print figures should be not shown as arrows in tactile:
1. Double headed arrow is often used as indications of length or distance measurement. It should be changed to two end bars (to show the beginning and end of the measurement) with a line across in between (for the student to trace).
2. Arrows are often used as lead lines in print. Well, we should not use arrows as lead lines in tactile, if we need to use any.
