Abstract: A system and method for providing an on-demand user interface for an input device. The system includes a first device and a second device. The first device is configured to receive a first user input and select a first notification from a plurality of notifications stored on the first device based at least in part on the first user input. The first device then outputs the first notification using one or more hardware resources. The second device detects the first notification output by the first device and matches the first notification to a first content item stored on the second device. The first content item includes instructions for providing a second user input on the first device. The second device then renders the first content item on a display. The first device further receives the second user input subsequent to the first user input.

Abstract: An example processing system for a capacitive input device includes a first interface coupled to at least one first electrode of at least one lighting element and a second interface coupled to at least one second electrode of the at least one lighting element spaced apart from the at least one first electrode. A controller is configured to: forward-bias the at least one lighting element during first time periods to provide illumination; drive the at least one first and the at least one second electrodes with substantially the same voltage during second time periods; and drive the at least one first electrode with a modulated voltage relative to a reference voltage while guarding the at least one second electrode during third time periods to measure capacitance. A determination module is configured to determine presence of at least one input object in a sensing region based on changes in the capacitance.

Abstract: A touch sensor device and method is provided that facilitates improved device usability. Specifically, the touch screen device and method provide user interface functionality while reducing the possibility of inadvertent activation of certain functions. The touch screen device comprises a proximity sensor adapted to detect object presence in a sensing region, a display screen overlapping the sensing region, and a processor. The touch screen device is adapted to provide user interface functionality by facilitating the display of user interface elements and the selection and activation of corresponding functions. For certain functions, the touch screen device and method uses the presence of a second object to confirm selection of a function before that function will be performed. So configured, the touch device screen is able to reduce the likelihood of inadvertent activation for certain functions on the device.

Abstract: A proximity sensor device and method is provided that facilitates orientation changes in displays. The proximity sensor device and method provide a user with the ability to indicate an orientation change in a display using the sensing region of a proximity sensor device as a user interface. In one specific embodiment, proximity sensor device is implemented to indicate an orientation change in a first way responsive to detected object motion along the sensing region in a first direction, and is further implemented to indicate an orientation change in a second way responsive to detected object motion along the sensing region in a second direction. Thus, a user can cause orientation changes of different ways through the use of object motions in different directions along the sensing region.

Abstract: Pointing apparatus and method provide for control of cursor movement and selection of elements on a computer screen. Gyroscopic elements within the pointing apparatus indicate yaw and pitch movements in free space, and a mouse ball and mouse ball encoders indicate movement on a surface. Data indicative of the distance and direction the cursor is to be moved is generated from outputs of the gyroscopic elements and the mouse ball encoders. Certain amounts of movement are deemed unintentional, and, if necessary, the pointing apparatus adjusts the data so as not to indicate movement of such amounts. By doing so, the pointing apparatus minimizes unintentional cursor movement caused by instability of the gyroscopes and the inability of a person to hold the pointing apparatus absolutely motionless.

Abstract: An arrangement for spacing a floating body from a mother vessel during borehole-seismic measurements, wherein the floating body includes at least two buoyant bodies connected by a rigid framework and which supports the seismic equipment, the floating body is maintained in a correct position for transmitting seismic pulses by a crane or boom mounted on the mother vessel, a tube or hose system is mounted on the framework for ejecting a pressurized medium, preferably water, against the side of the vessel through nozzles, and the pressurized medium is transferred to the system through a hose coupled to a source of pressurized fluid on board the vessel.
