DIY Head Mounted Displays Moving Towards Augmented Reality

چکیده
The field of Augmented Reality (AR) is growing rapidly. Many of the options available now are very expensive, which is limiting to development of applications of the technology. We have designed and developed several opensource do-it-yourself (DIY) head-mounted displays for augmented reality (AR) that cost between $4 to $40. Optical design and simulations were completed using Zemax for a design with a lens and a flat beam splitter (on-axis model) and for a single curved optical component (off-axis model). One demonstration of the on-axis model and two variations of the off-axis model were made. Each device aims to display the data from a projection source while at the same time allowing the user to see the real world around him/her with minimal obstruction. The effect is similar to Google Glass, but with some limitations to make it affordable and easily made by a wide range of potential users. The three main components in our design are: 1) a smart-phone screen as the projection source, 2) a curved clear plastic as the beam splitter and 3) cardboard as the body of the system.

Multiple Head Mounted Displays in Virtual and Augmented Reality Applications
With the recent introduction of low cost head mounted displays (HMDs), prices of HMD-based virtual reality setups dropped considerably. In various application areas personal head mounted displays can be utilized for groups of users to deliver different context sensitive information to individual users. We present a hardware setup that allows attaching 12 or more HMDs to a single PC. Finally we ...

Augmented Reality Enabled Collaborative Work in “Studierstube”
We introduce a multi-user augmented reality system to support collaboration of participants in research, presentation and education. Our system “Studierstube” presents threedimensional stereoscopic images simultaneously to a group of users wearing see-through head mounted displays. The displays do not affect natural communication and interaction, making working together very effective. Users se...

In augmented reality (AR) systems using headmounted displays (HMD's), it is important to accurately sense the position and orientation (pose) of the user's head with respect to the world, in order that graphical overlays are drawn correctly aligned with real world objects. It is desired to maintain registration dynamically (while the person is moving their head) so that the graphical objects wi...
