Multi-user collaborative software applications may synchronize data between multiple users or multiple devices. There are multiple existing ways to synchronize data. Some of these synchronization methods, such as file locking, are easy to implement but have performance or functionality drawbacks. Operational transformation (OT) is a high performance synchronization method, but difficult and time-consuming to implement in many cases, and cannot be partially implemented throughout a system. Methods and systems provide for blending operational transformation with other synchronization methods in the same collaborative software application, allowing operational transformation to be used in situations where it cannot be implemented throughout a system.

Blended operational transformation for multi-user collaborative applications

Multi-user real-time collaborative software applications may synchronize data between multiple users or multiple devices. Current aspects describe a method and system for enabling undo operations in collaborative software applications where not all possible actions adhere to the operational transformation properties. Certain aspects herein operate in the absence of the so-called Inverse Property 2 (IP2).

Method and system for concurrent collaborative undo operations in computer application software

An electronic device includes a display including a touch sensor, a contextual sensor configured to provide data indicative of an operating condition of the electronic device, one or more memories in which touch input instructions, touch event mapping instructions, and a touch event mapping model are stored, and a processor coupled to the memory. The processor is configured through execution of the touch input instructions to obtain data indicative of an initial assessment of touch event position via the touch sensor. The touch event mapping model maps the initial assessment of touch event position to an adjusted touch event position as a function of the data indicative of the operating condition of the electronic device. The processor is further configured through execution of the touch event mapping instructions to determine the adjusted touch event position based on the touch event mapping model, the data indicative of the initial assessment of touch event position, and the data indicative of the operating condition.

Model-based touch event location adjustment

An entertainment system includes an object tracking camera, a logic subsystem operatively connected to the object tracking camera, and a data holding subsystem holding instructions executable by the logic subsystem. The instructions are executable to receive one or more images of a scene from the object tracking camera, the scene including a human and a companion object. The instructions are further executable to recognize a gesture of the human based on the received one or more images, and to wirelessly send a control command to the companion object responsive to the recognized gesture.

Companion object customization

A game-interactive customizable companion object includes a body, a communication subsystem housed within the body, and a behavior subsystem configured to control movement of the body. The behavior subsystem may include an initiation module configured to set initial behavioral characteristics of the companion object in accordance with the companion object profile, and an update module configured to change behavioral characteristics of the companion object responsive to control commands received from the entertainment system via the communication subsystem.
