Publication number: 20100322550Abstract: An optical finger navigation device. Embodiments of the optical finger navigation device include a light guide film (LGF) including a finger interface surface, a light source in optical communication with the LGF to provide light from the light source to the finger interface surface, a sensor, and a navigation engine. At least a portion of the LGF exhibits total internal reflection (TIR). The sensor detects light from the LGF in response to contact between a finger and the finger interface surface which modifies reflection of light out of the LGF to the sensor. The light detected by the sensor is changed over at least a portion of the sensor in response to the contact between the finger and the finger interface surface. The navigation engine is configured to generate lateral movement information indicative of lateral movement of the finger relative to the sensor, in response to the detected light.Type: ApplicationFiled: June 18, 2009Publication date: December 23, 2010Applicant: AVAGO TECHNOLOGIES ECBU IP (SINGAPORE) PTE.

Publication number: 20080042975Abstract: A user observes an object in a visual scene and moves a user-controlled pointing device that measures magnetic fields to control or move the object. One or more magnetic sensors are included within the user-controlled pointing device and each magnetic sensor measures a magnetic field component associated with a respective orthogonal direction. A processing circuit receives an output signal from each magnetic sensor that represents the respective magnetic field component measured by that sensor. The processing circuit then tracks the movement of the pointing device using the output signals received from each magnetic sensor. Positional information for the object is determined based on the tracked movement of the user-controlled pointing device. The positional information is transmitted to a controller associated with the object using a communications link established between the pointing device and the controller.Type: ApplicationFiled: August 18, 2006Publication date: February 21, 2008Inventor: Gary R.
