Abstract: Various implementations disclosed herein include devices, systems, and methods that associate user activities with user interface (UI) elements within a 3D environment. Some implementations do so in ways that account for inaccuracies (i.e., fuzziness) in sensor-based detection of the user activities, e.g., inaccuracy in sensor data-based gaze tracking or sensor data-based hand/joint position. Some implementations use a sampling technique to associate user activity in a 3D environment with an appropriate portion of a UI positioned within a 3D environment. For example, a sampling technique may be used to identify sample locations within the 3D environment (e.g., sample locations around a gaze direction) to evaluate and ultimately select from to associate with a user activity, e.g., associating a particular UI button with a gaze direction.

Abstract: Systems and methods are disclosed for determining whether a message received by a client may be spam, in a computing environment that preserves privacy. The message may be encrypted. A client invokes the methods when a message is received from a sender that is not known to the client. A client can decrypt the message, break the message into chunks, and apply a differentially private algorithm to the set of chunks. The client transmits the differentially private message sketches to an aggregation server. The aggregation server receives a large collection of such message sketches for a large plurality of clients. The aggregation server returns aggregated message chunk (e.g. frequency) information to the client to assist the client in determining whether the message may be spam. The client can process the message based on the determination without disclosing the message content to the server.

In some implementations, a user can adjust playlist criteria by manipulating a list of representative music tracks. In some implementations, a user can compare the user's playlist to playlists of other users.

Abstract: In devices with flexible displays, multilayer adhesive stacks may be included. A multilayer adhesive may attach a flexible display panel to the display cover layer in an electronic device. Including multiple layers of adhesive in the adhesive stack (as opposed to a single layer) provides more degrees of freedom for the tuning and optimization of the properties of the adhesive stack. The multilayer adhesive stack therefore has better performance than if only a single layer of adhesive is used. The multilayer adhesive stack may include one or more layers of soft adhesive, hard adhesive, hard elastomer, hard polymer, and/or glass to optimize the mechanical and optical performance of the multilayer adhesive stack. Soft adhesive layers may be included to optimize lateral decoupling (e.g., during folding and unfolding) of the adhesive stack. Harder layers may be included to provide rigidity and prevent denting during impact events.
