Abstract
Depth perception is an important component of many augmented reality applications. It is, however, subject to multiple error sources. In this study, we investigated depth judgments with a stereoscopic video see-through head-mounted display for the purpose of designing depth cueing for systems that operate in an individual's action space. In the experiment, we studied the use of binocular disparity and relative size to improve relative depth judgments of augmented objects above the ground plane. The relative size cue was created by adding auxiliary augmentations to the scene according to constraints described in the section on the underlying theory. The results showed that binocular disparity and relative size improved depth judgments over the distance range. This indicates that for accurate depth judgments, additional depth cues should be used to facilitate stereo- scopic perception within an individual's action space. © The Authors.

Highlights
Space perception refers to the process by which the sensation of the physical space is transformed into the perceived space
The Distance variable had more than two conditions (N 1⁄4 4), and we had to test the assumption of sphericity of Distance for signed and absolute errors
We studied the effects of depth cues on depth judgments of augmented objects above ground plane within distances from 6 to 10 m
Summary
Space perception refers to the process by which the sensation of the physical space is transformed into the perceived space. This study focuses on depth perception within an individual’s action space using a video see-through head-mounted display (HMD). In a video see-through HMD, the viewer sees the surrounding scene through images that are captured by head-mounted cameras. Another technique for implementing see-through capability in a display is based on a semitransparent screen. The benefit of video see-through displays is that the rendering of scenes (e.g., latency, colors, and depth of field) can be matched to real-world imagery.[2,3,4] the perception of the real world with video see-through display is adversely affected by some characteristics of cameras and displays such as resolution limitations and optical distortions.[5,6]. 11 m 2.3 deg 25 deg AOI 1 m 0.5 m AA 0.2 m would require more accurate calibration and a higherresolution HMD (see Sec. 3.9)
