Haptic feedback stylus and other devices
First Claim
1. An apparatus, comprising:
- a stylus configured to be manipulated against a surface and configured to be held in a hand of a user;
a sensor configured to send at least one sensor signal to a host computer based on a coordinate position of the stylus only when the stylus is moved against the surface; and
an actuator disposed within the stylus and configured to apply a haptic sensation in response to the at least one sensor signal indicating the stylus at a designated coordinate position on the surface, wherein the actuator applies the haptic sensation while the stylus is in contact with the surface.

Abstract
A force feedback interface and method including an actuator in a non-primary axis or degree of freedom. The force feedback interface device is connected to a host computer that implements a host application program or graphical environment. The interface device includes a user manipulatable object, a sensor for detecting movement of the user object, and an actuator to apply output forces to the user object. The actuator outputs a linear force on the user object in non-primary linear axis or degree of freedom that is not used to control a graphical object or entity implemented by the host computer, and movement in the non-primary degree of freedom is preferably not sensed by sensors. The axis extends through the user object, and there are preferably no other actuators in the device, thus allowing the force feedback device to be very cost effective. Force sensations such as a jolt, vibration, a constant force, and a texture force can be output on the user object with the actuator. The force sensations can be output in a direction perpendicular to a planar degree of freedom, radial to spherical degree of freedom, and/or along a lengthwise axis of the user object.

13. An apparatus comprising:
-
a stylus; a sensor in communication with a host computer, the sensor configured to detect a coordinate position of the stylus against a surface and provide a coordinate position signal associated with the coordinate position of the stylus only while the stylus is moved along the surface; and an actuator coupled to the stylus, the actuator configured to vibrate in response to the sensor detecting the coordinate position of the stylus and the coordinate position signal indicating the stylus is positioned at a designated location on the surface. - View Dependent Claims (14, 15, 16, 17, 18)

19. A method for applying a haptic effect to a stylus comprising:
-
sensing a coordinate position of a stylus against a surface to produce a sensed signal; sending a coordinate position signal to a host computer only when the stylus is moved along the surface, the coordinate position signal associated with the sensed signal and indicating the coordinate position of the stylus along the surface; and applying a force from an actuator to the stylus in response to the coordinate position signal indicating the stylus being at a designated location on the surface, wherein haptic sensation is applied while the stylus is in contact with the surface. - View Dependent Claims (20, 21)
