One of the main goals of augmented reality is placing virtual content in the real world at a precise location. To achieve this goal, the Head Mounted Display (HMD) should be able to place virtual content at a precise location, and the users should be able to perceive at the exact location. However, achieving this task is very challenging. Since the birth of augmented reality, researchers have been trying to design AR glasses which can do this. Recently AR researchers by taking advantage of SLAM algorithms are able to come closer to the first phase of this goal. Microsoft designed and manufactured a pair of smart glasses called the HoloLens. It is well known for its advanced SLAM algorithm to place the content in a precise location as close as possible. However, there is no significant research on the perceptual location of the virtual content which are placed through Hololens. Therefore this thesis presents a method for measuring the perceived location of virutal objects, and presents an experiment, where these measurements are made with the Hololens. Through this experiment, interesting information about HoloLens was found, such as the capability of regaining tracking immediately after occlusion, rightward error about the horizontal plane, and bias of floating the virtual content above the surface, and objects that appear to close to the observer. Therfore Hololens is an advanced AR display, it still suffers from these problems.
