This paper proposes a wearable Hyperboloidal Head Mounted Projective Display (HHMPD), and reports on three user studies on the evaluation of visual quaity of a wearable HHMPD. Using a hyperboloidal mirror, an HHMPD can provide a wide field-of-view (FOV), a large observational pupil, and optical see-through capability. We propose a simple head attached screen that is both retro-reflective and semi transparent thereby allowing a HHMPD to be available in a wearable condition. Our user studies have shown that our wearable HHMPD provides a virtual image with a visual acuity of around 20/200 at perceptually 2 to 3 meters away from the user, and that users are able to identify visual stimuli in the periphery of the visual field up to ± 50 degrees in horizontal, while paying attention to a real object in frontal direction.
