摘要：
Methods and systems for dynamic virtual convergence (218) and a video see through head mountable display (200) that uses dynamic virtual convergence are disclosed. A dynamic virtual convergence algorithm (218) includes sampling an image with two cameras. The cameras each have a field of view that is larger than a field of view of displays used to display images sampled by the cameras (210). A heuristic is used to estimate the gaze distance of the viewer. The display frustums are transformed so that they converge at the estimated gaze distance. The images sampled by the cameras (210) are then reprojected into the transformed display frustums. The reprojected images are displayed to the user to simulate viewing of close range objects.
