摘要:
An interactive display that uses a planar radiation guide (such as a planar light guide) to perform display and/or imaging. The planar radiation guide has a radiation propagation portion and a radiation interface portion. The radiation propagation portion propagates the radiation by the principles of total internal reflection (with perhaps some minor leakage). The planar radiation guide also has a radiation interface portion where radiation is more apt to exit or enter the planar radiation guide. The interactive display performs both display and imaging, while the planar radiation guide is used to perform at least one (but perhaps both) of the display and imaging operations.

A system and method are disclosed for setting interactions between paired computing devices. Paired devices may interact in a master-slave relationship, where the slave device is an intelligent computing device capable of performing a wide variety of functions for the master computing device. When initiating a paired relationship, various characteristics relating to the initiating device are recorded, and the used in defining the relationship between the initiating device and the target device with which the initiating device paired. In a further example of interactions between paired computing devices, user-defined policies may be recorded, stored and implemented which affect the behavior of one or both computing devices when the two devices are paired.

Methods and apparatus for distributing power and data to devices coupled to the human body are described. The human body is used as a conductive medium, e.g., a bus, over which power and/or data is distributed. Power is distributed by coupling a power source to the human body via a first set of electrodes. One or more devices to be powered, e.g., peripheral devices, are also coupled to the human body via additional sets of electrodes. The devices may be, e.g., a speaker, display, watch, keyboard, etc. A pulsed DC signal or AC signal may be used as the power source. By using multiple power supply signals of differing frequencies, different devices can be selectively 15 powered. For example, a 100 Hz signal may be used to power a first device while a 150 Hz signal may be used to power a second device. Digital data and/or other information signals, e.g., audio signals, can be modulated on the power signal using frequency and/or amplitude modulation techniques. The power source and peripheral devices can interact to form a complete computer network where the body serves as the bus coupling the devices together. Devices can include optional batteries, one or more CPUs, transmit/receive circuitry, and/or input/output circuitry. In one particular exemplary network implementation the first device to be placed on the body operates as a master device, e.g., bus master, with one or more subsequently added devices working as slaves.

An infrared source is configured to illuminate the underside of one or more objects on or above a touchable surface of a touch panel. Infrared light reflected from the underside of the object(s) is detected by an infrared sensor integrated in the touch panel below the touchable surface.

摘要:
Hardware input devices can provide context sensitive labels which can change according to an application running on a computer and/or the function assigned to an input element. An illustrative aspect includes employing ink having two or more electroluminescent pattern layers with an input device. Based on the context of a computer associated with the input device, an illuminated pattern identifies the current functionality of one or more of the inputs of the input device.
摘要:
An interactive display device employing a flat panel display (FPD). The interactive display device includes a housing, a flat panel display, a light diffusing layer, a visible light illumination system, and a non-visible light illumination system that is used for detecting objects adjacent to the FPD. Techniques are also described for providing uniform illumination of the FPD with visible light, when viewed from a plurality of viewing angles by a user, and for diffusing the visible illumination at a surface boundary of the FPD, such that a coherent image of an interior of the housing is at least partially obscured from view by the user. Non-visible light that has passed through the FPD is reflected from objects adjacent to the display, passes back through the FPD, and is detected within the housing.
摘要:
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.
摘要:
A keyboard having an input region that provides a set of input elements designed to complement a separate pointing device such as a computer mouse. These input elements enable both the dominant and non-dominant hand to work easily together to perform various functions, which in turn, makes “consumption” and “composition” tasks more efficient. The input region may be spaced laterally from the alphanumeric or “QWERTY” section of the keyboard. The elements include a scrolling member, first and second groups of keys, and an application switching device. The scrolling member may take the form of a rotatable member. The rotatable member may have an asymmetric outer profile and/or be frustum-shaped. The first group of keys preferably includes a Back key and a Forward key. The first group of keys and the scrolling member make performing “consumption” tasks more efficient. The second group of keys preferably includes a Cut key, a Copy key, and a Paste key. The application switching device is preferably configured to provide a command, when actuated, to move between open applications. The application switching device may be independently-actuable, and/or dedicated and labeled as an application switching device. Additionally, the application switching device may be movable for actuation in opposing directions. Exemplary embodiments of the application switching device include a toggle switch, a rotatable dial, a laterally slidable member, and one or two keys. The second group of keys, application switching device and the scrolling member make performing “composition” tasks more efficient.
