Concept of the Joint Use of Smartphone Camera and Projector for Keyboard Inputs

  • The efficiency of text input by today’s smartphones is significantly limited by the small extents of the virtual keyboard displayed for allowing alphanumeric inputs. Future smartphones will integrate projectors which allow to project multimedia content as well as the smartphones’ dialogs. This paper introduces a concept to project the whole smartphone’s display onto a surface allowing the user to realize text inputs by interacting with the virtual keyboard projection. This projection is analyzed by standard image processing algorithms. Finally, an experimental implementation shows the feasibility of this concept.
