Haptic sensations for tactile feedback computer interface devices. In one
method, a tactile sensation is output during the interaction of a cursor and a
graphical object, the tactile sensation being based on a periodic waveform and
having a frequency correlated with a size of the graphical object interacted with
the cursor. Another method includes receiving an indication of a position of a
cursor, causing the cursor to snap to a graphical object, such as a line, when
the cursor is within a predetermined distance so that the cursor can be moved along
or within the graphical object, and enabling the output of a vibration sensation
while the cursor is moved along or within the object. In another method, a tactile
sensation includes a pop sensation that is a short, high magnitude sensation, and
then a ringing sensation during or immediately after the output of the pop sensation
and which can fade in magnitude over time.
