1. A haptic input device held by a user, comprising:
- a housing defining a tapered input end to interact with a screen of a touch-based user interface device, the housing enclosing;
a receiver within the tapered input end and configured to wirelessly receive a signal from the touch-based user interface device, the received signal corresponding to a touch input gesture provided to the screen by the user and detected by the touch-based user interface device;
a decoder to extract an input signal from the received signal;
a controller to generate a control signal based on the input signal;
a haptic actuator to provide a first haptic feedback response corresponding to the control signal;
a sensor to determine an orientation of the haptic input device relative to the touch-based user interface device; and
a transmitter to transmit the orientation to the touch-based user interface device;
whereinthe haptic actuator is configured to provide a second haptic feedback based on the orientation.

Abstract
One embodiment of a haptic input device may include a receiver configured to receive a signal from a touch-based user interface device. The signal may include a control signal or a look-up value. The haptic input device may also include a decoder coupled to the receiver and configured to decode the signal from the touch-based user interface device, at least one sensor configured to determine at least one characteristic of the haptic input device, a controller coupled to the one or more sensors and configured to transmit a control signal, a haptic actuator coupled to the controller, and a transmitter coupled to the at least one sensor.

10. A method for providing haptic feedback, comprising:
-
detecting an input gesture by at least one input sensor of a touch-sensitive input device, the input gesture performed by a stylus in contact with a touch screen surface of the touch-sensitive input device; deriving, by a processor within the touch-sensitive input device, an orientation characteristic of the stylus; receiving, by the processor, a signal from the stylus comprising a acceleration characteristic of the stylus; determining, by the processor, a haptic response based on the orientation characteristic, the acceleration characteristic, and the input gesture; and transmitting a haptic output signal to the stylus, the haptic output signal comprising a look-up value corresponding to the haptic response, the output signal instructing the stylus to provide the haptic response. - View Dependent Claims (11, 12, 13, 14, 15)

16. A haptic input device, comprising:
-
a housing comprising an input end and a sensor end, the input end configured to contact a touch-sensitive surface of a user interface device; a receiver within the input end and configured to receive a modulated signal from the user interface device, the modulated signal corresponding to a gesture input provided by the input end to the touch-sensitive surface; a demodulator in communication with the receiver and configured to extract an input signal from the modulated signal; a sensor within the sensor end and configured to provide sensor data based on an orientation characteristic of the haptic input device relative to the user interface surface; and a controller in communication with the demodulator and the sensor and configured to generate a control signal based in part on the input signal and in part on the sensor data; a haptic actuator coupled to the controller and configured to provide a haptic feedback response based on the control signal; and a transmitter configured to transmit the sensor data to the user interface device such that an output of the user interface device is modified based on the sensor data;
wherein the sensor end is opposite the input end.
