Abstract: A virtual reality system is described herein. The virtual reality system includes a cane controller and a computing system. The cane controller comprises a rod, a sensor, and a brake mechanism, wherein the sensor is configured to generate a signal that is indicative of position, direction of movement, and velocity of the rod, and wherein the brake mechanism is configured to apply a force to the rod. The computing system receives the signal, computes a position, direction of movement, and velocity of a virtual rod in a virtual space, and outputs a control signal to the brake mechanism based upon such computation. The brake mechanism applies the force to the rod in a direction and with a magnitude indicated in the control signal, thereby preventing the user from causing the virtual rod to penetrate a virtual barrier in the virtual space.

Abstract: Aspects relate to detecting gestures that relate to a desired action, wherein the detected gestures are common across users and/or devices within a surface computing environment. Inferred intentions and goals based on context, history, affordances, and objects are employed to interpret gestures. Where there is uncertainty in intention of the gestures for a single device or across multiple devices, independent or coordinated communication of uncertainty or engagement of users through signaling and/or information gathering can occur.

Abstract: Described herein are various technologies pertaining to presenting search results to a user, wherein the search results are messages generated by way of social networking applications. An interactive graphical object is presented together with retrieved messages, and messages are filtered responsive to interactions with the interactive graphical object. Additionally, a graphical object that is indicative of credibility of a message is presented together with the message.

Abstract: The systems and techniques described herein implement an improved gaze-based on-screen keyboard that provide dynamically variable dwell times to increase throughput and reduce errors. Utilizing a language model, the probability that each key of the on-screen keyboard will be the subsequential key can be determined, and based at least in part on this determined probability, a dwell time can be assigned to each key. When used as an iterative process, a minimum dwell time may be gradually reduced as confidence in the subsequential key increases to provide a cascading minimum dwell time.

Abstract: Information sharing between meeting attendees during a co-located group meeting in a meeting space is democratized using a computer that is operating cooperatively with one or more object sensing devices in the meeting space to identify postures formed by the meeting attendees.

Abstract: Some examples include transitioning between an individual mode and a collaborative mode in response to an orientation change of a device. Further, some implementations include identifying data to be shared with one or more other devices (e.g., co-located devices) in the collaborative mode. In some examples, the individual mode may be associated with an individual search, the collaborative mode may be associated with a collaborative search, and the devices may transition between the individual mode and the collaborative mode in response to orientation changes.

Abstract: The subject disclosure is directed towards using credibility-related data in conjunction with servicing a web request such as a search query or a request for page content. The credibility-related data may be used to convey information to a user indicative of a level of credibility, such as to view credibility information with each search result, or in association with returned web page content. The credibility-related data may be used to rank, re-rank and/or filter search results. Also described is extracting credibility-related feature data from search-related data and web pages, and using the feature data with a dataset of credibility-rated pages to learn/train relative feature weights in a credibility model used by the search engine.

Abstract: Systems and methods are provided to perform collaborative retrieval, communication, and navigation of electronic content in a co-located environment. In an illustrative implementation, a collaborative content environment comprises a collaborative content interface engine, and an instruction set comprising at least one instruction providing instructions to the collaborative content interface engine to process data representative of inputs from two or more cooperating interface devices to allow for the retrieval, communication, search, and navigation of electronic content. In the illustrative implementation, the collaborative content interface engine can present retrieved, communicated, searched, and/or navigated data according to a selected display paradigm. The display paradigm can include one or more display portions of a display pane comprising data responsive to the inputs received from the two or more cooperating interface devices.
