Axis orientation compensation is provided in a system in which movement of a controlling device is used to control navigational functions of a target appliance by determining which one of plural sides of the controlling device is an active side of the controlling device and by causing navigational functions of the target appliance made relative to at least one of an X, Y, and Z axis of the target appliance to be dynamically aligned with movements of the controlling device made relative to at least one of an A, B, and C axis of the controlling device as a function of the one of the plural sides of the controlling device that is determined to be the active side of the controlling device.

A gesture recognition device includes a sensor unit having at least one sensor and a controller connected to the sensor unit. The controller is operable in a training mode and a trained mode. When the controller is operated in training mode, the controller is configured to allow selection of a domain followed by at least one of a selection and a creation of corresponding gestures using a domain module. The controller in the training mode is further configured to receive input signals from the sensor unit for the corresponding gestures, to apply a filter module corresponding to the selected domain to generate filtered datasets, and to train a gesture engine based on the filtered datasets. When the controller is operated in the trained/identification mode, the controller is configured to identify the gesture.

A remote access device and methods of operation thereof are provided for accessing a physical object or location. The remote access device includes an accelerometer, a wireless transmitter, and control circuitry. The control circuitry causes the wireless transmitter to transition between a first operating mode and a second operating mode in response to receiving signals from the accelerometer indicating a first change in motion states of the remote access device. The control circuitry causes the wireless transmitter to transition between a first operating mode and a second operating mode in response to receiving signals from the accelerometer indicating a second change in motion states of the remote access device. The control circuitry further causes the wireless transmitter to transition between the first operating mode and the second operating mode in response to receiving signals from the accelerometer indicating a third change in motion states of the remote access device.

A method for performing a directional operation includes: obtaining an operation directing to a target operation device; determining a direction of the operation, determining the target operation device matched with the direction of the operation; and performing the operation on the target operation device.

A control device may be configured to control one or more electrical loads in a load control system. The control device may be a wall-mounted device such as dimmer switch, a remote control device, or a retrofit remote control device. The control device may include a gesture-based user interface for applying advanced control over the one or more electrical loads. The types of control may include absolute and relative control, intensity and color control, preset, zone, or operational mode selection, etc. Feedback may be provided on the control device regarding a status of the one or more electrical loads or the control device.

A traceable optical device is capable of being tracked by an electronic device having an image sensor. The traceable optical device includes a light guide member, at least one light source, and a shielding member. The light guide member has at least one light-incident surface and a light-emitting surface connected to each other. The light source is configured to emit light into the light guide member from the light-incident surface. The shielding member shields the light guide member and has at least one light transmission area.

A sensor controller includes a transmitter configured to transmit an uplink signal including a first partial signal and a second partial signal. The transmitter is configured to transmit the first partial signal by direct spreading using a first spread code and transmit the second partial signal by direct spreading using a second spread code which is different from the first spread code and which has an identical chip time length to the first spread code. An active stylus includes a receiver configured to receive an uplink signal including a first partial signal and a second partial signal. The receiver is configured to synchronize with the uplink signal by detecting the first partial signal using a first spread code and thereafter detect the second partial signal using a second spread code, which is different from the first spread code and has an identical chip time length to the first spread code.

Techniques for acoustic management of entertainment devices and systems are described. Various embodiments may include techniques for acoustically determining a location of a remote control or other entertainment device. Some embodiments may include techniques for controlling one or more entertainment components using voice commands or other acoustic information. Other embodiments may include techniques for establishing a voice connection using a remote control device. Other embodiments are described and claimed.

Systems, interfaces, and methods for implementing the systems and interfaces includes selection attractive movement as the selection protocol, where a selection object is used to discriminate between selectable objects and attract a target object toward the selection objects, where the direction and speed of the motion controls, discriminates, attracts, and activates the selected objects.

Methods and apparatuses are provided for remote-controlling a target apparatus using a mobile communication terminal. A communication link is established with the target apparatus having a display screen adapted to visualize an object. An amount of movement of the mobile communication terminal is detected. Motion information for moving the object is generated using the amount of movement of the mobile communication terminal. The motion information is transmitted to the target apparatus. The amount of movement is detected based on at least one of current position information, acceleration information, and angular velocity information of the mobile communication terminal.
