    摘要: The claimed subject matter provides a system and/or a method that facilitates enhancing interactive surface technologies for data manipulation. A surface detection component can employ a multiple contact surfacing technology to detect a surface input, wherein the detected surface input enables a physical interaction with a portion of displayed data that represents a corporeal object. A physics engine can integrate a portion of Newtonian physics into the interaction with the portion of displayed data in order to model at least one quantity related associated with the corporeal object, the quantity is at least one of a force, a mass, a velocity, or a friction.

    摘要: Speckle sensing for motion tracking is described, for example, to track a user's finger or head in an environment to control a graphical user interface, to track a hand-held device, to track digits of a hand for gesture-based control, and to track 3D motion of other objects or parts of objects in a real-world environment. In various examples a stream of images of a speckle pattern from at least one coherent light source illuminating the object, or which is generated by a light source at the object to be tracked, is used to compute an estimate of 3D position of the object. In various examples the estimate is transformed using information about position and/or orientation of the object from another source. In various examples the other source is a time of flight system, a structured light system, a stereo system, a sensor at the object, or other sources.

    摘要: A depth-sensing method for a time-of-flight depth camera includes irradiating a subject with pulsed light of spatially alternating bright and dark features, and receiving the pulsed light reflected back from the subject onto an array of pixels. At each pixel of the array, a signal is presented that depends on distance from the depth camera to the subject locus imaged onto that pixel. In this method, the subject is mapped based on the signal from pixels that image subject loci directly irradiated by the bright features, while omitting or weighting negatively the signal from pixels that image subject loci under the dark features.

    摘要: Methods and devices for providing a user input to a device through sensing of user-applied forces are described. A user applies forces to a rigid body as if to deform it and these applied forces are detected by force sensors in or on the rigid body. The resultant force on the rigid body is determined from the sensor data and this resultant force is used to identify a user input. In an embodiment, the user input may be a user input to a software program running on the device. In an embodiment the rigid body is the rigid case of a computing device which includes a display and which is running the software program.

    摘要: Touch detection systems and methods are described. The system comprises a light guiding sheet, a light source, a reflective layer and a detector. When a fingertip or other suitable object is pressed against the light guiding sheet, light which is undergoing total internal reflection within the sheet is scattered. The scattered light is reflected by the reflective layer and detected by the detector. In an embodiment, the light is infra-red light. The touch detection system may, in some embodiments, be placed on a display and the touch events used to control the display.
