Locator-Dots, also called Loc-Dots, are tactile markers designed for use by individuals who are blind or have low vision.
These plastic, adhesive-backed dots are clear and can be used to mark light switches, oven controls, house keys, alarm clocks, telephones, tape recorders, etc.
They can also be used as keytop overlays to designate certain keys on a computer keyboard. The package contains six dots, and is available in clear (see-thru) or orange.
Stick them to any clean surface where a tactile marking will prove helpful.
Each dot measures 3/16th an inch, with the raised portion of the dot measuring 1/16 inch.
