A non-Bluetooth device operates in a same frequency band as Bluetooth devices by employing a method of intelligent frequency hopping. The method includes: scanning a frequency band for frequency hopping communications in the frequency band by one or more Bluetooth communication devices communicating according to a Bluetooth communication protocol; determining a first frequency hopping sequence utilized by the one or more Bluetooth communication devices according to the Bluetooth communication protocol; determining a second frequency hopping sequence within the frequency band to avoid interference from the frequency hopping communications by the one or more Bluetooth communication devices; and establishing a wireless communication connection between two non-Bluetooth devices, the wireless communication connection operating in the frequency band according to a second wireless communication protocol different than the Bluetooth communication protocol, and using the second frequency hopping sequence.

Method and device for intelligent frequency hopping in a shared frequency band

A user device is disclosed which includes a touch input and a keypad input. The user device is configured to operate in a gesture capture mode as well as a navigation mode. In the navigation mode, the user interfaces with the touch input to move a cursor or similar selection tool within the user output. In the gesture capture mode, the user interfaces with the touch input to provide gesture data that is translated into key code output having a similar or identical format to outputs of the keypad.

Translation of directional input to gesture

Illumination spot alignment is performed by capturing an image by an image array. The image is evaluated to determine an illumination spot size and location. Coordinates identifying the illumination spot size and location are stored.

Illumination spot alignment

A system and method for tracking the x, y and z coordinates of a position of an input device in an interactive computer system is disclosed. An image sensor situated on the input device captures images of an electronic marker displayed on a display screen. As the position of the input device changes, the features of the electronic marker as captured by the image sensor also change. Images of the electronic marker captured during game play are compared to a calibration image of the electronic marker to determine current x, y and z coordinates of positions of the input device. The game display is updated to reflect the movements of the input device.

System and method for interactive three-dimensional position tracking

In one embodiment, a surface is navigated by 1) using a first light sensor, mounted to a navigation device, to detect light reflected from a surface, and 2) using outputs of the first light sensor, over time, to determine relative movement of the navigation device with respect to the surface. While using the first light sensor, it is determined whether the outputs of the first light sensor, over time, are indicating movement of the navigation device with respect to the surface. If not, 1) a second light sensor that is mounted to the navigation device, and of a different type than the first light sensor, is used to detect light reflected from the surface, and 2) outputs of the second light sensor, over time, are used to determine relative movement of the navigation device with respect to the surface.

Methods and apparatus for navigating a surface

A pointing device and method for operating the same is disclosed. The pointing device includes an illumination system, a camera system, and a controller. The illumination system illuminates a surface over which the pointing device moves. The illumination system generates a light level determined by an illumination control signal. The camera records a plurality of images of the illuminated surface. The controller records first and second images taken by the camera at different times and determines a displacement indicative of the direction and distance the positioning device moved between the two different times. The controller also generates the illumination control signal. The illumination control signal depends on at least one of the images recorded by the camera system. In one embodiment, the surface is characterized by a reflectivity and the light level generated by the illumination system is inversely related to that reflectivity.

Pointing device with adaptive illumination level

In one embodiment, movement between a surface and an imager is tracked by using the imager to acquire a series of digital images of the surface. Each of the digital images represents a pattern of light that is reflected from the surface. If a first number of the digital images have surface qualities that are above a surface quality threshold set to an initial value, ones of the series of digital images are compared to track movement between the surface and the imager. If a second number of the digital images have surface qualities that are below the surface quality threshold, then i) the surface quality threshold is dynamically lowered to a new value, and thereafter ii) ones of the series of digital images are compared to track movement between the surface and the imager. Other embodiments are also disclosed.
