Multifocal planes head-mounted displays

Applied Optics, 2000
Stereoscopic head-mounted displays (HMD's) provide an effective capability to create dynamic virtual environments. For a user of such environments, virtual objects would be displayed ideally at the appropriate distances, and natural concordant accommodation and convergence would be provided. Under such image display conditions, the user perceives these

Amplifying Head Movements with Head-Mounted Displays [PDF]

Presence: Teleoperators and Virtual Environments, 2003
The head-mounted display (HMD) is a popular form of virtual display due to its ability to immerse users visually in virtual environments (VEs). Unfortunately, the user's virtual experience is compromised by the narrow field of view (FOV) it affords, which is less than half that of normal human vision.

Engineering of head-mounted projective displays

Applied Optics, 2000
Head-mounted projective displays (HMPD's) are a novel type of head-mounted display. A HMPD consists of a miniature projection lens mounted upon the user's head and retroreflective sheeting material placed strategically in the environment. First, the imaging concept of a HMPD is reviewed and its potential advantages and disadvantages are discussed.

Patient monitoring with head-mounted displays

Current Opinion in Anaesthesiology, 2009
Head-mounted displays (HMDs) are head-worn display devices that project an information display over the wearer's field of view. This article reviews a recent program of research that investigates the advantages and disadvantages of monitoring with HMDs, and discusses the design considerations and implementation issues that must be addressed before HMDs

Head-Mounted Display System for Microneurosurgery

Stereotactic and Functional Neurosurgery, 1997
Advances in video technology have enabled the incorporation of high-resolution electronic imaging of an operative field during microneurosurgical and endoscopic procedures. While current video-based monoscopic camera and monitor systems produce an excellent image, the third dimension is lacking and the operative field and image are at different ...

High-resolution inset head-mounted display

Applied Optics, 1998
A novel approach to inset superimposition in a high-resolution head-mounted display (HMD) is presented. The approach is innovative in its use of optoelectronic, nonmechanical devices in place of scanning mechanical devices commonly adopted previously.
