AIM Wearable technology interfaces with normal human movement and function, thereby enabling more efficient and adaptable use.We developed a wearable display system for use with intra-operative neuronavigation for brain tumor surgery. MATERIAL AND METHODS The Google glass head-up display system was adapted to surgical loupes with a video-streaming integrated hardware and software device for d...

Screen-readers |computer software that enables a visually impaired user to read the contents of a visual display| have been available for more than a decade. Screen-readers are separate from the user application. Consequently, they have little or no contextual information about the contents of the display. The author has used traditional screen-reading applications for the last ve years. The de...

In Virtual Reality, considerable systematic spatial orientation problems frequently occur that do not happen in comparable real-world situations. This study investigated possible origins of these problems by examining the influence of visual field of view (FOV) and type of display device (head-mounted display (HMD) vs. projection screens) on basic human spatial orientation behavior. In Experime...

This paper presents two vision-based interface systems. The first, Visual Screen, uses an inexpensive technique to transform an ordinary screen into a touch screen using an ordinary camera. The setup is easy: position a camera so it can see the whole screen. The system calibration involves the detection of the screen region in the image, which determines the projective mapping between the image...

The so-called “blue-c” is a novel three sided immersive projection system, which has been especially designed to support telecollaborative teamwork [4]. Therefore, special projection screens are used, which can be switched to a transparent state electrically. The user is captured with sixteen cameras in total, standing outside of the projection room. These images are then processed to create a ...

We have developed a technique that changes the image seen on a screen depending on the viewing angle. A new display apparatus for video conferences based on this technique projects multiple images of participants taken from different angles onto a directional screen consisting of a directional diffusion plate and lens. This display apparatus provides us with the natural feeling and comfort of d...

A new technique for multi-view autostereoscopic projection display is proposed, and demonstrated. The technique uses two mobile projectors, a rotating retro-reflective diffuser screen, and a head-tracking camera. As two dynamic viewing slits are created at the viewer's position, the slits can track the position of the eyes by rotating the screen. The display allows a viewer to move approximatel...

As users pan and zoom, display content can disappear into off-screen space, particularly on small-screen devices. The clipping of locations, such as relevant places on a map, can make spatial cognition tasks harder. Halo is a visualization technique that supports spatial cognition by showing users the location of off-screen objects. Halo accomplishes this by surrounding off-screen objects with ...
