A polarized head-mounted projective display

Fourth IEEE and ACM International Symposium on Mixed and Augmented Reality (ISMAR'05), 2005
The lack of image brightness is a common problem in optical see-through head-mounted displays (OST-HMD) where a beamsplitter is required to combine views from HMD image source and the direct-view of a real world scene. This problem is further aggregated in a head-mounted projective display (HMPD) due to the fact that light passes through the ...

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

Prolonged work with head mounted displays

Proceedings of the 2014 ACM International Symposium on Wearable Computers: Adjunct Program, 2014
This paper sums up the main results from a research project focusing on prolonged work with head mounted displays and the effect on physiological and mental strain.

Multisensory Integration with a Head-Mounted Display and Auditory Display

Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2008
Human operators who use head-mounted displays (HMDs) in their work may benefit from auditory support. It is unclear whether auditory support is better delivered in free-field or via earpiece, and what the effect of walking is. To examine this problem, a novel multisensory integration task was created in which participants identified mismatches between ...

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.

An approach for user identification for head-mounted displays

Proceedings of the 2015 ACM International Symposium on Wearable Computers - ISWC '15, 2015
A head-mounted display (HMD) is a device, worn by a person, which has a display in front of one or both eyes. HMDs have applications in a variety of domains including gaming, virtual reality, and medicine. In this paper we present an approach that can identify a user, from among a group of users, by synchronously capturing their unconscious blinking ...

The use of a head-mounted display for visualization in neuroendoscopy

Computer Aided Surgery, 2004
To evaluate the clinical use of a head-mounted display (HMD) for visualization in all neuroendoscopic procedures.We retrospectively evaluated all endoscopic and endoscope-controlled procedures in which the HMD was used in our department between July 1999 and June 2002.A total of 269 endoscopic procedures were performed.

A Mobile Head-Mounted Display for Action Sports

2012 Third FTRA International Conference on Mobile, Ubiquitous, and Intelligent Computing, 2012
We describe a highly portable head-mounted display designed for use in action sports such as skiing and snowboarding. The low field-of-view, monocular display is designed to keep distraction to a minimum and not impede the mobility of the wearer. Implications of the location of the monocular display are discussed.

Dynamic light amplification for head mounted displays

Proceedings of the 16th ACM Symposium on Virtual Reality Software and Technology, 2009
Two common limitations of modern Head Mounted Displays (HMD): the narrow field of view and limited dynamic range, call for rendering techniques that can circumvent or even take advantage of these factors. We describe a simple practical method of enhancing visual response from HMDs by using view-dependent control over lighting.

Thumbnail Input for Head-Mounted Display

2015
In this work, we propose an input interface for mobile head-mounted display. A camera is attached on frames of glasses to take pictures below. When users lift their hand so that the camera can see their thumbnail, the system recognizes it and detects its position. Measured position is used for inputting command for controlling the head-mounted display.
