Abstract: Image data representing a two-dimensional image is received. Symbols are extracted from the image data using a detection service. The symbols are encoded into representation vectors, each representing distinct symbols. A labeled two-dimensional image is generated by (i) performing a comparison between a representation vector and representation vectors of symbols included in a library of known symbols, (ii) in accordance with determining that the corresponding representation vector exceeds a threshold similarity with a particular representation vector, applying a first label to the symbol, wherein the first label is a label of a first symbol that is represented by the particular representation vector, and (iii) in accordance with determining that the corresponding representation vector does not exceed the threshold similarity with representation vectors, applying a second label to the symbol.

Abstract: A user computing device displays a three-dimensional virtual space via a user interface. The user computing device detects a gesture input at a location of the user interface. The user computing device translates the gesture input into a user interface input by predicting, based on the gesture input, a design intended by the gesture input and mapping, based on the design and the location of the gesture input on the user interface, the design to the user interface to generate the user interface input. The user computing device executes, in response to the user interface input, an operation to add an object in the three dimensional virtual space. The user computing device renders an updated three dimensional space displaying the object.
