In this work, effects of stereoscopic view on object recognition and navigation performance of the participants are examined in an indoor Desktop Virtual Reality Environment, which is a two-floor virtual museum having different floor plans and 3D object models inside. This environment is used in two different experimental settings: 1) color-multiplex stereoscopic 3D viewing is provided by colored eye-wear, 2) regular 2D viewing. After the experiment, participants filled a questionnaire that inquires their feeling of presence, their tendency to be immersed and their performance on object recognition and navigation in the environment. Two groups (3D and 2D), each having 5 participants, with equal tendency are formed according to the answers of 'tendency' part, and the rest is evaluated to examine the effects of stereoscopic view. Contrary to our expectations, results show no significant difference between 3D and 2D groups both on feeling of presence and object recognition/navigation performance.
