摘要： A user can make a symbol with their hand, or other such gesture, at a distance from a computing device that can be captured by at least one imaging element of the device. The captured information can be analyzed to attempt to determine the location of distinguishing features of the symbol in the image information. The image information is then compared to hand gesture information stored in, for example, a library of hand gestures for the user. Upon identifying a match, an input to an application executing on the computing device is provided when the image information contains information matching at least one hand gesture with at least a minimum level of certainty. The hand gesture could include a single “static” gesture, such as a specific letter in sign language, for example, or include two or more “static” gestures. The gesture could also include motion, such as hand movement.

摘要： A computing device and/or application executing on the device can utilize fingertip tracking using a camera. However, when the fingertip is in a dead zone (an area that is not viewable by the camera), the fingertip tracking cannot function properly. Nevertheless, the position of the fingertip, when in the dead zone, can still be estimated. An image of a user's hand can be captured by at least one camera. A portion of a pointing finger can be detected in the captured image. An orientation of the portion of the pointing finger can be determined. One or more joint lines of the pointing finger can be identified. Based on data about a slant and/or a bend of the pointing finger obtained using information relating to the identified joint line(s), and/or on data obtained via calibration and/or historic/current usage, the position of the fingertip, when in the dead zone, can be approximated.

摘要： A user can use a finger, or other such object, to provide input to a computing device. The finger does not have to contact the device, but can be positioned and/or oriented in such a way that the device can determine an input that the user is attempting to provide, such as an element or icon that the user is intended to select. One or more cameras can capture image information, which can be analyzed to attempt to determine the location and/or orientation of the finger. If the finger is at least partially outside a field of view of the camera(s), the device can use a sensor (e.g., EMF) to attempt to determine a location of at least a portion of the finger, which can be used with the image information to determine the location and/or orientation of the finger. Other estimation processes can be used as well.

摘要： The use of resources on a computing device can be optimized for current conditions to reduce or minimize the amount of resources needed to provide a sufficient level of performance for various types of tasks. In some embodiments, one or more optimization algorithms can analyze information such as a type of task to be performed and the state of one or more environmental conditions to attempt to select a number and configuration of components, such as cameras and illumination elements, to use in performing the tasks. The performance of the tasks can be monitored, and the selection or states updated in order to maintain a sufficient level of performance without using more resources than are necessary.

摘要： A user attempting to obtain information about an object can capture image information including a view of that object, and the image information can be used with a matching or identification process to provide information about that type of object to the user. Information about the orientation of the camera and/or device used to capture the image can be provided in order to limit an initial search space for the matching or identification process. In some embodiments, images can be selected for matching based at least in part upon having a view matching the orientation of the camera or device. In other embodiments, images of objects corresponding to the orientation can be selected. Such a process can increase the average speed and efficiency in locating matching images. If a match cannot be found in the initial space, images of other views and categories can be analyzed as well.

摘要： A method and an apparatus for allocating spectrums are provided in the disclosure. The method includes: reconfigurable spectrums for a target group domain are calculated, wherein said reconfigurable spectrums contain one or more of a dedicated spectrum, a reusable spectrum and a loanable spectrum; during the system reconfiguration, spectrums are allocated to cells of the target group domain in a non-overlap region after spectrums are allocated to cells of the target group domain in an overlap region according to the reconfigurable spectrums. By use of the disclosure, the spectrum allocation can be implemented during the system reconfiguration, and interference can be effectively suppressed.

摘要： The disclosure discloses a sensing aiding method for cognitive radio. The method includes the following steps. a high level node transmits configuration information to a base station; the base station combines with a subordinate node of the base station to perform frequency spectrum sensing measurement, in which the subordinate node has sensing capability, and feeds back a result of the sensing measurement to the high level node; and the high level node formulates a corresponding WS allocation policy according to the received result of the sensing measurement. The disclosure also discloses a system. By the method and the system of the disclosure, the high level node transmits the configuration information to the base station; the base station performs the spectrum sensing measurement in combination with the subordinate node having the sensing capability of the base station in a designated frequency band and feeds the result of the sensing measurement back to the high level node; and the high level node formulates the corresponding WS allocation policy according to the result of the sensing measurement. Available white band resources are acquired; the probability of base station configuration failure is reduced, and the overhead caused by configuration failures is reduced.

摘要： A user can emulate touch screen events with motions and gestures that the user performs at a distance from a computing device. A user can utilize specific gestures, such as a pinch gesture, to designate portions of motion that are to be interpreted as input, to differentiate from other portions of the motion. A user can then perform actions such as text input by performing motions with the pinch gesture that correspond to words or other selections recognized by a text input program. A camera-based detection approach can be used to recognize the location of features performing the motions and gestures, such as a hand, finger, and/or thumb of the user.
