Abstract:
We present the evaluation of a bimanual augmented reality (AR) interaction technique, and focus on the effect on viewpoint and image reversal on human performance The interaction technique (called flip-flop) allows the user to interact with a 3D object model by using a V-shaped AR menu placed on a desk in front of her/him. The menu is made of two complementary submenus. Both submenus (master and slave) are made of four Artag fiducial markers. The functionalities of the slave submenu are the following : (1) increase/decrease the size or rotate/stop the 3D object, (2) apply a color (one over four) or (3) a 2D texture (one over four) on the 3D object and (4) apply predefined material parameters. Each event is triggered by a masking of a Artag marker by the the user’s right or left hand. 40 participants were instructed to perform actions such as rotate the object, apply a texture or a color on it, etc. The results revealed some difficulties due to the inversion of the image on the screen
. Finally, although the proposed interaction technique is currently used for product design, it may also be applied to other fields such as edutainment, cognitive/motor rehabilitation, etc. Moreover, other tasks than the ones tested in the experiment may be archived using the menu.
