Dynamic updating of projected keyboard models to increase typing efficiency of a user

A computer program product comprising:

• one or more non-transitory computer-readable storage media;
• and
• program instructions stored on the one or more non-transitory computer-readable storage media to perform operations comprising:
• causing a first keyboard model to be projected on a surface;
• causing cameras to monitor a first user with respect to at least three coordinate planes;
• collecting first information based on multiple positions of palm(s) of the first user with respect to multiple of the coordinate planes;
• collecting second information based on vertical palm movement and/or horizontal finger shifts of the first user with respect to a first plane of the at least three coordinate planes;
• determining, based on the first information and the second information, updates for increasing a typing efficiency of the first user;
• generating a second keyboard model, wherein the second keyboard model is a version of the first keyboard model modified to include the determined updates;
• and
• causing the second keyboard model to be projected,
• wherein the determined updates include rearranging a placement of a first key of the first keyboard model in the second keyboard model,
• wherein the rearranging the placement of the first key of the first keyboard model in the second keyboard model comprises:
• centering the first key at a forecasted location of a key pressing event on the second keyboard model.
