Abstract: The subject disclosure is directed towards detecting symbolic activity within a given environment using a context-dependent grammar. In response to receiving sets of input data corresponding to one or more input modalities, a context-aware interactive system processes a model associated with interpreting the symbolic activity using context data for the given environment. Based on the model, related sets of input data are determined. The context-aware interactive system uses the input data to interpret user intent with respect to the input and thereby, identify one or more commands for a target output mechanism.

Abstract: Various technologies described herein pertain to simulating oil painting. Data can be received from a sensor that indicates a desired orientation of an image editing tool with respect to a computer-implemented canvas. The computer-implemented canvas can include a paint map, which includes color values and height values of pixels representative of oil paint deposited on the computer-implemented canvas. Moreover, a footprint of the image editing tool upon the computer-implemented canvas can be computed based upon the data from the sensor. Further, an oil paint ridge model can be generated by modulating height values of a subset of the pixels from the paint map that are outside the footprint and less than or equal to a predetermined distance from an edge of the footprint. A display screen of a computing device can be caused to update an image rendered thereupon based upon the oil paint ridge model.
