The effect of cursor shape and size on pointing efficiency

Graphical interfaces contribute to the ease of use of computers. Interfaces based on WIMP (windows, icons, menus, and pointer) have made it possible for users to perform tasks efficiently with a few mouse clicks. However, problems like deteriorating eyesight make it difficult for many middle-aged and older people to see the cursor. There is an extensive range of literature demonstrating selection strategies which address such problems. However, the effect of the shape of the tip of a cursor on pointing efficiency is still not clear. The most commonly used cursor shape is an arrow. It´s hard to say at this stage what shape of cursor is the best. The minute tip of the cursor is difficult to see and to place precisely into a target. Accurate placement of the cursor requires a keen eye, a steady hand and delicate motion of the hand. This causes significant physical and psychological burdens such as shoulder and neck stiffness and emotional fatigue. Thus, this research focused on the effect of the shape and size of the cursor on pointing efficiency for middle-aged and older adults. Thus, we seek to find the best shape for cursors.
