TECHNIQUES TO AUTOMATICALLY UPDATE SOFTWARE APPLICATIONS

Techniques to automatically update software applications are described. An apparatus may comprise a processor and a memory. The memory may store an update component that when executed by the processor is operative to manage updates for an application program. The update component may comprise an update manager and a permission manager. The update manager may be operative to update a file version for one or more application files of the application program and store one or more current file version identifiers for the one or more application files of the application program in the memory. The permission manager may be operative to receive a communication request to communicate with a remote device from the application program prior to communicating information to the remote device, and send a communication response granting or denying the communication request to the application program based on the one or more current file version identifiers. Other embodiments are described and claimed.

Gestures And Gesture Recognition For Manipulating A User-Interface

Symbolic gestures and associated recognition technology are provided for controlling a system user-interface, such as that provided by the operating system of a general computing system or multimedia console. The symbolic gesture movements in mid-air are performed by a user with or without the aid of an input device. A capture device is provided to generate depth images for three-dimensional representation of a capture area including a human target. The human target is tracked using skeletal mapping to capture the mid-air motion of the user. The skeletal mapping data is used to identify movements corresponding to pre-defined gestures using gesture filters that set forth parameters for determining when a target’s movement indicates a viable gesture. When a gesture is detected, one or more pre-defined user-interface control actions are performed.

PERSONALIZED NAVIGATION USING A SEARCH ENGINE

Personalized navigation for one or more individuals’ use of a search engine is provided. Identification of a query submitted to the search engine is performed. If the query is identified to be a personal navigational query, which is a query via which the individuals intend to navigate to a particular site or information object that they have previously viewed, the particular site or information object associated with the query is identified, and results of the search are personalized based on knowledge of the identified site or information object.

LEARNING TRANSPORTATION MODES FROM RAW GPS DATA

Described is a technology by which raw GPS data is processed into segments of a trip, with a predicted mode of transportation (e.g., walking, car, bus, bicycling) determined for each segment. The determined transportation modes may be used to tag the GPS data with transportation mode information, and/or dynamically used. Segments are first characterized as walk segments or non-walk segments based on velocity and/or acceleration. Features corresponding to each of those walk segments or non-walk segments are extracted, and analyzed with an inference model to determine probabilities for the possible modes of transportation for each segment. Post-processing may be used to modify the probabilities based on transitioning considerations with respect to the transportation mode of an adjacent segment. The most probable transportation mode for each segment is selected.

Image Browsing and Navigating User Interface

Techniques for image browsing, navigating and user interface operation are described herein. An image cube, having three axes representing a medical patient’s body parts, imaging technology and image date, may be displayed on a visual display. Image piles of icons or thumbnail images may be positioned within the image cube, according to the three axes. By fixing the body parts axis on a specific body part, an image plane may be selected from the image cube. The selected image plane replaces the image cube in the visual display, including only image piles of the selected body part, organized according to axes indicating imaging technology and image date. An image pile may be selected from the image plane, to replace the image plane on the visual display. Image pile operations allow the user to select from the image pile a desired image(s) for display.
