The LipStick features in detail

control by force

Only minimal head movements are necessary to move the cursor. The required force can be adjusted from very small to as large as one likes. At maximum sensitivity, less than 10 grams of force will move the cursor.

precise cursor control

Excellent control over both very small and large cursor movements. Very precise at small movements. Pixel by pixel control is quite possible. Automatic acceleration for large and fast movements. Screen cursor movements are smooth and free of unwanted jumps.

mouse clicks with lips

Left or right mouse clicks are produced by lifting the upper or lower lip, not by sipping or puffing as in other mouth controlled devices.
Free choice which lip controls which mouse button. Mouse dragging is easily accomplished.
