摘要:
An interactive table has a display surface on which a physical object is disposed. A camera within the interactive table responds to infrared (IR) light reflected from the physical object enabling a location of the physical object on the display surface to be determined, so that the physical object appear part of a virtual environment displayed thereon. The physical object can be passive or active. An active object performs an active function, e.g., it can be self-propelled to move about on the display surface, or emit light or sound, or vibrate. The active object can be controlled by a user or the processor. The interactive table can project an image through a physical object on the display surface so the image appears part of the object. A virtual entity is preferably displayed at a position (and a size) to avoid visually interference with any physical object on the display surface.

Various embodiments are disclosed relating to a keyboard with integrated key and touchpad. In an example embodiment, a keyboard is provided that includes a plurality of keys, each key being capable of being pressed to select one or more keyboard inputs. The keyboard also includes a micro touchpad provided on an upper surface of a first key of the keys to allow pointer control by moving a finger or other object across a top surface of the micro touchpad.

A hand held computer input device includes a first housing portion having at least one user actuable input device. A first extending handle is coupled to, and extends away from, the first housing portion. A second handle is also coupled to, and extends away from, the first housing portion. An orientation sensor is coupled to the first housing and is configured to sense a physical orientation of the first housing portion. The orientation sensor provides an orientation signal indicative of the physical orientation sensed.

A method and system uses an acceleration curve to enhance data navigation. In a preferred embodiment, the scrolling algorithm of an input device with a rotational member accelerates a resultant scroll amount in direct relation to a rotational speed of the rotational member. The acceleration curve may be implemented in a look-up table in the mouse driver. Different acceleration curves may be used based upon whether a user is scrolling up or scrolling down. In a further embodiment, acceleration is temporarily inhibited upon the occurrence of a change in the direction of rotation of the rotational member.

In a computer system, a touch sensitive input device having touch sensitive auxiliary controls system can be used to anticipate a user's action. When a user's hand approaches a touch sensitive input device, feedback can be displayed on a display screen. A user can receive feedback without activating the input device. The feedback may take the form of status information related to the feature controlled by the input device and can vary depending upon the application open. Likewise, when the hand of a user is moved away from the touch sensitive input device, the feedback brought on by sensing the user's hand may disappear.

A computer keyboard has a grid of conductors forming a plurality of intersections, with force-sensitive resistor (FSR) elements located between the conductors at the intersections. A plurality of keys are located above the intersections and exert force on the conductors and FSR elements during key presses. A resistor network sub-circuit is connected to some of the conductors, and is switchable between low and high resistance values. An Analog to Digital Converter (ADC) is coupled to the resistor network sub-circuit. A microprocessor grounds a conductor and tests another conductor for a threshold voltage level while the resistor network is switched to the high resistance value. The microprocessor switches the resistor network to the low resistance value upon detecting the threshold voltage level and subsequently receives from the ADC a digital value of a voltage on the tested conductor.

Embodiments are disclosed that relate to hover detection in interactive display devices. One embodiment provides an interactive display device comprising a display panel configured to display an image on an interactive surface, an imaging optical wedge disposed adjacent to the display panel, an image sensor configured to capture an image of an object located in front of the interactive surface and spaced from the interactive surface by capturing the image through the imaging optical wedge, a logic subsystem, and a data-holding subsystem comprising instructions executable by the logic subsystem to operate the display panel and the image sensor, and to detect a hover input based upon one or more images received from the image sensor.

Disclosed herein are techniques for scaling and translating gestures such that the applicable gestures for control may vary depending on the user's distance from a gesture-based system. The techniques for scaling and translation may take the varying distances from which a user interacts with components of the gesture-based system, such as a computing environment or capture device, into consideration with respect to defining and/or recognizing gestures. In an example embodiment, the physical space is divided into virtual zones of interaction, and the system may scale or translate a gesture based on the zones. A set of gesture data may be associated with each virtual zone such that gestures appropriate for controlling aspects of the gesture-based system may vary throughout the physical space.

A docking station for an electronic device includes a magnet that holds the electronic device in a mated orientation relative to the docking station. The docking station may include a mounting surface with two or more different charge-contact regions, each charge-contact region electrically coupled to a terminal of an electric power source and positioned to form an electrical connection with a charging terminal of the electronic device when the electronic device mates with the mounting surface.

A sensor manager provides dynamic input fusion using thermal imaging to identify and segment a region of interest. Thermal overlay is used to focus heterogeneous sensors on regions of interest according to optimal sensor ranges and to reduce ambiguity of objects of interest. In one implementation, a thermal imaging sensor locates a region of interest that includes an object of interest within predetermined wavelengths. Based on the thermal imaging sensor input, the regions each of the plurality of sensors are focused on and the parameters each sensor employs to capture data from a region of interest are dynamically adjusted. The thermal imaging sensor input may be used during data pre-processing to dynamically eliminate or reduce unnecessary data and to dynamically focus data processing on sensor input corresponding to a region of interest.
