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.

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

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 ...

Contrast budget of head-mounted displays

Optical Engineering, 2002
This paper introduces the concept of a contrast budget for a head-mounted display, i.e., a list of contrast values of separate contrast-degrading phenomena in the system. The basic phenomena are dynamic range, diffraction, scattered light, and ghost images.

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.

The Eyephone: a head-mounted stereo display

SPIE Proceedings, 1990
Head mounted stereo displays for virtual environments and computer simulations have been made since 1969. Most of the recent displays have been based on monochrome (black and white) liquid crystal display technology. Color LCD displays have generally not been used due to their lower resolution and color triad structure.

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.

An Introduction to Head Mounted Displays for Augmented Reality

2007
This chapter introduces design and principles of head mounted displays (HMDs), as well as their state-of-the-art examples, for augmented reality (AR). Section 2 introduces a brief history of head mounted displays, human vision system, and application examples of see-through HMDs.
