  • Patent number: 9946803
    Abstract: Instances of content, such as search results or browse items, can be displayed using a plurality of three-dimensional elements, with selected pieces of information for each instance placed upon faces, sides, or other portions of those elements. A user can view similar information for each of the instances of content by rotating the elements, such as by interacting with an input element or rotating a portable computing device rendering the elements. The user can apply various filtering criteria or value ranges, whereby the relative position of the elements in three-dimensional space can be adjusted based at least in part upon the applied values. By rotating the elements, applying criteria, and changing the camera view of the elements, a user can quickly compare a large number of instances of context according to a number of different criteria, and can quickly locate items of interest from a large selection of items.

  • Patent number: 9754016
    Abstract: A user interacting with an electronic device can receive suggestions for applications or services that can help the user with a specific task. The user might enter information that can be processed semantically to determine one or more actions, objects, or other types of information useful in discovering related applications or services, which might be local or remote to that device. One or more of these discovered applications or services is selected to suggest to the user based on any number of criteria, such as user behavior, preferences, location, time of day, etc. Using such an approach, a device can utilize a semantic process to attempt to infer an action or intent relating to a simple or complex task, and can discover and suggest applications or services that can assist with that task even where the user is unaware of, or not looking for, such an application or service.

  • Patent number: 9747847
    Abstract: Embodiments provide techniques for updating pixels of an electrophoretic display through computational modeling of a current state of each pixel. A model buffer may store data for a modeled current state of each pixel in a display, providing a prediction of a current color state for each pixel based on voltages previously applied to the pixel. Upon receiving a frame to be displayed, including a target state for each pixel, embodiments determine which of a set of voltages (e.g., positive, negative, or neural/zero voltages) optimally alters the state of the pixel to be as close as possible to the target state. These voltage(s) may be applied to each pixel in an iterative manner, with each voltage determined based on the current modeled state of the pixel.

  • Patent number: 9557811
    Abstract: Input can be provided to a computing device based upon relative movement of a user or other object with respect to the device. In some embodiments, infrared radiation is used to determine measurable aspects of the eyes or other of a user. Since the human retina is a retro-reflector for certain wavelengths, using two different wavelengths or two measurement angles can allow user pupils to be quickly located and measured without requiring resource-intensive analysis of full color images captured using ambient light, which can be important for portable, low power, or relatively inexpensive computing devices. Various embodiments provide differing levels of precision and design that can be used with different devices.

  • Patent number: 9280652
    Abstract: An unlock procedure for an electronic device can be based at least in part upon a determined gaze direction or viewing location of a user. During a device unlock process, the user can be directed to follow an element or path on a display element with the user's eyes. Image information captured of the user during this process can be used to correlate the user's eye position in the image with the corresponding gaze location on the device, in order to calibrate the gaze tracking in a way that is substantially transparent to the user. Further, certain devices can also utilize captured image information during the unlock process to authenticate the user using a process such as iris recognition or retinal scanning. Such an approach enables secure access to the device without requiring the user to manually enter identifying information, and re-authentication can be performed without distracting the user.

  • Patent number: 9232353
    Abstract: An electronic device can utilize image capture technology to detect the presence and location of another device. Using this information, the electronic device can display, in a user interface, a graphical element representing a detected device, along with identity information and the location of the detected device relative to the electronic device. The location of each detected device relative to the electronic device can be tracked and thus the graphical element can be updated in the user interface.

  • Patent number: 9170318
    Abstract: Electronic devices can identify other nearby devices, and determine the relative positions of those devices, using a combination of techniques. Various devices are able to project one or more instances of a unique identifier, such as a barcode, which can be imaged by other devices. The devices also can communicate position and/or orientation information over a wireless sideband channel. By combining the information relating to the projected identifier with information collected over the sideband channel, devices can automatically determine the location of various devices and associate a user or device identity with those devices. A user of a device then can view relative locations of those devices on a display element, including information about the user of the device. Further, the relative position determinations can enable a user to perform certain functions with respect to another device based at least in part upon the position and/or identity of that device.

  • Patent number: 9013416
    Abstract: An electronic device including two or more display elements can provide enhanced functionality with improved rates of power consumption. A user can cause information that does not change rapidly to be provided or moved to a relatively static display element, such as an electronic ink display, which enables that information to be displayed for a period of time with little additional power consumption. Similarly, content (e.g., video) that changes rapidly can be displayed on a relatively dynamic display element, such as and LCD or OLED display. Each display can be touch sensitive, such that a user can move content between the displays by pressing on, or making a motion in contact with, at least one of the displays. Various modes can be activated which cause certain types of content to be displayed on the dynamic and/or static display element.
