Abstract: A plurality of data items can be managed using a processor. The plurality of data items can be contributed by a plurality of applications. The plurality of data items can include at least scheduled events, scheduled tasks and previous activities. Information corresponding to at least the scheduled events, scheduled tasks and previous activities can be presented. The plurality of data items can be managed based on knowledge and meaning of content of the plurality of data items.

Abstract: Coordination and handling of communications can include sending, from a requesting device to a recipient device prior to establishing a communication session with the recipient device, a request for the communication session and receiving, within the requesting device, a reply to the request from the recipient device. Responsive to the reply, the communication session is scheduled within the requesting device based upon the reply.

Abstract: In one embodiment, a method includes detecting user input linked to a portion of a graphical user interface associated with one or more applications. The method further includes rendering, in response to the detected user input, at least a portion of a transient graphical object that is made up of several portions. Each portion is associated with a different virtual space, and each portion contains content including at least: 1) information linked to a particular one of the one or more applications; and 2) one or more graphical control objects for initiating one or more actions linked to the particular application.

Abstract: The touch sensor is a touch sensor that senses changes in characteristics of the electromagnetic signal in an environment in order to detect the contact or the proximity.

Abstract: In one embodiment, a method includes accessing a first context data associated with a first touch event on a first device and accessing a second context data associated with a touch event on the first device. The touch event has been detected by a second device. The method further includes comparing the first context data with the second context data and determining, based on the comparison, whether the first touch event is the touch event detected by the second device.

Abstract: In one embodiment, a method includes receiving, by an electrode of a device, a signal from a user's body. The received signal is based on an electromagnetic interference signal generated by an object that is external to the device. The method further includes determining, using machine learning applied to the received signal, one or more of the following: an identity of the object, an interaction between the user and the object, or a context surrounding the device.

Abstract: In one embodiment, an apparatus includes an electrode that is coupled to a body of a user and is configured to receive a signal from the body. The received signal is based on an electromagnetic interference signal generated by an object that is external to the apparatus. The apparatus further includes one or more processors coupled to the electrode. The processors are configured to detect, based on the signal received by the electrode, one or more of: an interaction between the user and the object, an identity of the object, or a context surrounding the apparatus.

Abstract: The touch sensor is a touch sensor that senses changes in characteristics of the electromagnetic signal in an environment in order to detect the contact or the proximity.

Abstract: In particular embodiments, an apparatus includes a single electrode configured to passively receive a charge displacement and a change in characteristics of electromagnetic signals in an environment. The apparatus further includes a touch sensor, coupled to the single electrode, configured to detect a first input based on the charge displacement, and a second input based on the change in characteristics of electromagnetic signals in the environment.

Abstract: In particular embodiments, an apparatus includes an insulator coupled to one or more electrodes that are configured to passively sense charge displacement or a change in characteristics of electromagnetic signals in an environment.

Abstract: In particular embodiments, a method includes receiving a signal from an electrode of a touch sensor that senses a charge displacement, based on the signal, in order to detect the contact or separation. The method further includes detecting a contact or separation input to the touch sensor.
