Climbing With a Head-Mounted Display

Human Factors, 2016
Objective: We explored the dual-task costs of climbers performing a visual communication task using a head-mounted display (HMD) while simultaneously climbing along a vertical surface. Background: Climbing is affected by secondary ...

Effect of Head-Mounted Displays on Posture

Human Factors: The Journal of the Human Factors and Ergonomics Society, 2007
Objective: The aim of the present study was to determine if a wearable system based on a head-mounted display (HMD) causes users to alter their head position and adopt postures that place greater stress on the musculoskeletal system. Background: HMDs are common output devices used with wearable computers. HMDs provide the wearer with visual information

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.

Head mounted display with peripheral vision

Proceedings of the 2005 international conference on Augmented tele-existence - ICAT '05, 2005
In paper, we present a new inexpensive HMD design that provides peripheral vision by attaching two small low resolution LCD's on its sides. We are currently experimenting with the design to identify the appropriate system parameters, and planning to assess the effectiveness in terms of user felt presence and task performance.

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

Using keyboards with head mounted displays

Proceedings of the 2004 ACM SIGGRAPH international conference on Virtual Reality continuum and its applications in industry - VRCAI '04, 2004
Alphanumeric input is often required in many computer applications. Virtual reality (VR) applications are no exception. For instance, enabling the alphanumeric input can augment a typical VR based walkthrough system so that the user can make notes and annotations. However, methods for efficient alphanumeric input for HMD-based VR systems have only been

Head-Mounted Display System for Microneurosurgery

Stereotactic and Functional Neurosurgery, 1998
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 ...

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
