1. A method of controlling a touch sensitive panel of a computing device, said method comprising:

  • scanning said touch sensitive panel at a first rate to detect a user interaction therewith;

    detecting an event within said computing device, wherein said event is an identification of a surface type made based on metadata associated with a surface when compositing layers of surface data into a resultant image for display wherein said compositing layers further comprises;

    receiving said layers of surface data using a compositing module; and

    extracting surface type information from metadata associated with said surface data; and

    responsive to said event, scanning said touch sensitive panel at a second rate based on said surface type to detect a user interaction therewith, said second rate slower than said first rate wherein less power is consumed at said second rate versus said first rate and wherein further said event indicates a presence of a use case of said computing device in which any user interaction of said touch sensitive panel is limited.
