Monitoring interactions between two or more objects within an environment

A method for monitoring interactions between an input object and an interface object, comprising:

• receiving a depth map comprising depth data for pixels within a captured image of an environment;
• generate a depth derivative image from the depth map based upon computing depth derivatives for pixel clusters within the captured image using the depth data;
• iterating over the depth derivative image to identify an input object having depth derivative characteristics within predefined input object parameters;
• and
• iterating over the depth derivative image to identify an interface object having depth derivative characteristics within predefined interface object parameters, the input object distinguishable from the interface object.

A system for monitoring interactions between an input object and an interface object, comprising:

• a projection component configured to project an interactive interface onto an interface object;
• and
• a tracking component configured to:
• track an input object and the interface object in real-time within an environment by iteratively identifying the input object and the interface object within the environment based upon depth maps associated with captured images of the environment;
• and
• determine whether the input object is in a hover state or a touch state in relation to at least one of the interface object or the interactive interface based upon the tracking.
