Abstract
One or more techniques and/or systems are provided for monitoring interactions by an input object with an interactive interface projected onto an interface object. That is, an input object (e.g., a finger) and an interface object (e.g., a wall, a hand, a notepad, etc.) may be identified and tracked in real-time using depth data (e.g., depth data extracted from images captured by a depth camera). An interactive interface (e.g., a calculator, an email program, a keyboard, etc.) may be projected onto the interface object, such that the input object may be used to interact with the interactive interface. For example, the input object may be tracked to determine whether the input object is touching or hovering above the interface object and/or a projected portion of the interactive interface. If the input object is in a touch state, then a corresponding event associated with the interactive interface may be invoked.
