Mixed reality head-mounted display

2005 Digest of Technical Papers. International Conference on Consumer Electronics, 2005. ICCE., 2005
The mixed reality head-mounted display (MRHMD) is a video see-through head-mounted display supporting binocular vision for mixed reality applications, with customized hardware for real-time composition of video from natural scenes and rendered graphics from its supporting computer system.

Head mounted display

Displays, 2002
Abstract This chapter describes head mounted displays (HMDs) from the viewpoint of the human factors. Because it has two separate display systems, HMDs are especially effective in displaying stereoscopic images. To develop better stereoscopic three-dimensional display technologies, it is important to investigate visual functions such as accommodation

Natural Perspective Projections for Head-Mounted Displays

IEEE Transactions on Visualization and Computer Graphics, 2011
The display units integrated in today's head-mounted displays (HMDs) provide only a limited field of view (FOV) to the virtual world. In order to present an undistorted view to the virtual environment (VE), the perspective projection used to render the VE has to be adjusted to the limitations caused by the HMD characteristics.

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.

Climbing With a Head-Mounted Display

Human Factors: The Journal of the Human Factors and Ergonomics Society, 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 auditory cognitive tasks, and climbing impairs later recall of secondary task information; the effects of visually ...

Head Mounted Displays for Medical Use

Journal of Display Technology, 2008
Head Mounted Displays have been used in various forms to assist surgeons and other medical personnel to support and improve visualization of the work site. Historically, many of these were of inadequate resolution, bulky, cave-like and heavy and they, deservedly, received limited acceptance.

Next-generation head-mounted display

SPIE Proceedings, 2010
Head Mounted Displays (HMDs) have been utilized by the military for various applications since the 1980's. In the 1990's, this technology migrated to the consumer market. Most of these early systems suffered the major drawback that they were "look-at" versus "see through" systems, which prevented the user from seeing their environment.

Head mounted displays and deaf children

Proceedings of the 2014 conference on Interaction design and children, 2014
Headmounted displays (HMDs) are evaluated as a tool to facilitate studentteacher interaction in sign language. Deaf or hardofhearing children who communicate in sign language receive all instruction visually. In normal deaf educational settings the child must split visual attention between signed narration and visual aids. Settings in which visual aids

Owl pellets and head-mounted displays

Proceedings of the 12th International Conference on Interaction Design and Children, 2013
This demonstration will provoke discussion of the role of head mounted displays (HMD) in Deaf science education for children. The demonstration mimics the classroom laboratory experience of children who are Deaf or hard-of-hearing. When these children dissect an owl pellet, their teachers can not stand behind them and offer instruction over their ...
