Tactile Protractor with arm

Measuring Angles Made Easy for Visually Impaired Individuals A revolutionary tactile protractor enables people with visual impairments to accurately measure or draw angles. The device features tactile markings every 5 degrees, with prominent ticks at 30 and 45 degrees for effortless navigation. Two precision-crafted hands allow users to take precise measurements, one with a clever "bite out" design that facilitates accurate readings at 5-degree intervals from the starting point. In contrast, the unadorned hand can only reach down to approximately 10 degrees. The sturdy arm is securely fastened to the base by means of a screw that points upwards, ensuring stability and preventing accidental dislodging. A thoughtful recess on the base accommodates the screw's head, providing a snug fit and added reassurance.
