Draw and drag: accessible touchscreen geometry for students who are blind

The drawing of geometric shapes, such as rectangles or triangles of varying sizes, in geometry classes is inaccessible to blind students. Most solutions to this inaccessibility are inaccurate, low tech, time consuming, or require assistance. Draw and Drag is a research project to test the feasibility of using touchscreens to allow students who are blind to do their geometry homework easily and quickly without any assistance.
