Head mounted display with peripheral vision
Proceedings of the 2005 international conference on Augmented tele-existence - ICAT '05, 2005In 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.

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, 2004Alphanumeric 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

Contrast measurement of head-mounted displays
Optical Engineering, 2002We present a way to measure the contrast of helmet- mounted displays. Standards exist for direct view flat panel displays and projection displays, but head-mounted displays do not seem to be covered by the standards yet. We start by discussing a basic setup (4-mm aperture, lens, detector) with the aperture residing in the exit pupil of the display. A 4

Contrast budget of head-mounted displays
Optical Engineering, 2002This 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.

Thumbnail Input for Head-Mounted Display
2015In 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.
