OMNI TOUCH TECHNOLOGY

OmniTouch is a wearable depth-sensing

and projection system that enables

interactive multitouch applications on

everyday surfaces (Harrison, Benko,

Wilson, 2011).

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

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.
