Haptic sensations for tactile feedback interface devices
First Claim
1. A method for providing a haptic sensation to a user physically contacting a haptic feedback device, said haptic feedback device communicating with a host computer implementing a graphical environment, the method comprising:
- receiving an indication of an interaction of a user-controlled cursor with a graphical object in said graphical environment; and
enabling the output of a tactile sensation during said interaction, said tactile sensation being based on a periodic waveform and having a frequency correlated with a size of said graphical object interacted with said cursor.

Abstract
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.

11. A method for providing a haptic sensation to a user physically contacting a haptic feedback device, said haptic feedback device communicating with a host computer implementing a graphical environment, the method comprising:
-
receiving an indication of a position of a user-controlled cursor;
causing said cursor to snap to said graphical object when said cursor is within a predetermined distance of said graphical object in said graphical environment so that said cursor is displayed touching said graphical object and said cursor can be moved along or within said graphical object based on user manipulation of said haptic feedback device; and
enabling the output of a vibration sensation to the user while said cursor is moved along or within said graphical object. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 20, 21, 22, 23, 24, 25, 26, 27)

19. A method for providing a tactile sensation to a user physically contacting a haptic feedback device, the method comprising:
-
enabling the output of a pop sensation, said pop sensation being a short, high magnitude sensation; and
enabling the output of a ringing sensation during or immediately after said output of said pop sensation, said ringing sensation being commanded using a periodic waveform and having a longer duration and lower magnitude than said pop sensation.
