  9. 9. SURFACE SEGMENTATION &TRACKING
  10. 10. STRENGTHS enables interactive multitouch applications on everyday surfaces. uses the users hands, arms, and legs as graphical, interactive surfaces users can transiently appropriate surfaces from the environment to expand the interactive area eg books, walls, tables. uses all these surfaces without any calibration
  11. 11. WEAKNESS the system is sensitive to approach angle of fingers. require fingers to be outstretched to be recognisable. the system assumes that the user is a right hander projection distance limited classification driven approach suffers from scalability issues since it is not possible to build a classifier for every conceivable surface.
