Abstract: The subject matter of this specification generally relates to modular vehicles including separable pod and base units. In some implementations, a computing system installed in a vehicle base identifies a vehicle pod that is detachably connected to a chassis on the vehicle base. In response to identifying that the vehicle pod is detachably connected to the chassis on the vehicle base, a communications link can be established between the computing system installed in the vehicle base and a computing system installed in the vehicle pod. Based on information obtained through the communications link, the computing system installed in the vehicle base can determine a particular configuration of the vehicle pod that is detachably connected to the chassis. The computing system can then verify that the vehicle base can safely transport the vehicle pod while the vehicle pod is detachably connected.

Abstract: A method of providing decisions to user queries includes: receiving, by at least one processor, a query transmitted from a client device; identifying, from a query database, a first query model; applying, by the at least one processor, the identified first query model to multiple user experience data entries from a user experience database, to obtain at least one correlation resulting from the application of the first query model to the multiple user experience data entries; and identifying, by the at least one processor, an answer to the query from the at least one correlation.

Abstract: This specification describes technologies for mental state measurement using sensor data obtained from sensors attached to objects. One embodiment is a method that includes receiving sensor data from sensors attached to non-wearable objects. The first and second attachable sensors each include an output and a sensor. The method further includes determining mental state data from the sensor data; and causing to be displayed a representation of a mental state based on the mental state data. The method can further include: deriving an action metric from the mental state data; comparing the action metric to a threshold; automatically taking an action when the action metric exceeds the threshold; collecting post action sensor data; determining post action mental state data based at least in part on the post action sensor data; and forwarding the post action mental state data for display of a representation of a mental state.

Abstract: Systems and methods are disclosed for selecting from various mechanisms for displaying a message directed to particular user(s) and/or user account(s). The mechanism by which the message may be displayed may be determined based at least in part on prediction of the importance and/or a prediction of a time criticality of the message to the user(s) to whom the message is to be delivered. The message may be received or generated by a hub user device. If the hub user device is not in the process of displaying any content on a primary display screen associated with the hub user device, then the received or generated message may be displayed on the primary display screen.

Abstract: User interfaces for selecting content for presentation or other actions is described in this disclosure. Using a small number of input controls a user may quickly and easily navigate content available for presentation from one or more content providers. Additional information may be presented to the user to facilitate selection of the content. Users may select content using one or more of a graphical user interface, or voice input.

Abstract: Methods and apparatus are provided for user interface operation. In one embodiment, a method includes displaying a user interface including one or more graphical elements, wherein display of the user interface is associated with a display configuration, and detecting a user command associated with navigating to one or more previously displayed user interface display configurations. The method may further include storing a user interface configuration for the display configuration, and adjusting display of the user interface based on the user command.
