The multitouch tabletop display provides a collaborative workspace for multiple users around a table. Users can perform direct and natural multitouch interaction to
select target elements using their bare fingers. However,
physical size of fingertip varies from one person to another
which generally introduces a fat finger problem. Consequently, it creates the imprecise selection of small size target elements during direct multitouch input.
In this respect, an attempt is made
to evaluate the physical finger input properties i.e. contact area and shape in the context of imprecise selection
