Perceptual User Interface

Perceptual User Interface or PUI is an ultimate level interface. It is multimodal in the extreme, maximising the bandwidth of interchange between the person and the computer, fully engaging all of the user's senses, and completely immersing.

This creates the situation whereby the virtual world is interacted with no different from the physical world, and all but eliminates any difference between the two.

Below, we offer a selection of links from our resource databases which may match this term.

Large Image Display: Chrysalis: Natural User Interface in Surveilance
Part two of a short series looking at the French film Chrysalis (2007)'s take on Natural User Interfaces. This focusses on a slightly more advanced form of touchscreen display; dealing with video data in such a way as to feel totally natural, even to a non-computer-user.

Brain Machine Interface Enabled Wheelchair
Researchers at the University of South Florida have developed a wheelchair-mounted robotic arm, which is capable of interfacing with the wheelchair user's thoughts via a non-invasive neural interface.

Large Image Display: Chrysalis: Natural User Interface in Paperwork
A look at the tabletop interface system, a form of NUI that has long been sought after, but as the French film Chrysalis imagines it. A form which strongly resembles current efforts, but has the added benefit of being just a few years ahead of us, and is willing to show the capabilities off.

A Downside of Gesture-Control: Perceptual Power of Gestures Used by Others
A potential concern has been found in the psychological implications of gesture control interfaces. When we design such things we must be aware of a power some gestures have, to alter the perceptions and memories of those who witness them.

VR Interfaces: Vocal Joystick

The Vocal Joystick is a hardware interface for those with severe disabilities such as motor impairments. Provided they can make sounds with their larynx, even if they are not words, the user can navigate a virtual environment, or web page.

Spoken Dialogue Technology: Toward the Conversational User Interface

Spoken Dialogue Technology attempts to provide an exhaustive coverage of spoken dialogue systems. Based on the author?s earlier 80 page paper on the same subject, this book fleshes things out, whist still maintaining a fairly academic presentation style.

The Symphony of Smell, A New Approach to the Sense
We have never truly succeeded at a VR scent interface. All those we have, bar none, physically release a scent into the room around the user, because we have never been able to grasp how the brain processes the sense of smell. A novel study tracing individual nerve firings with mice in controlled conditions, reveals that the actual organisation of the sense of smell is far more complex than we ever dreamed.

The Human Brain has a Network Backbone
An unexpected discovery of a hierarchical networking scaffold inside the human brain itself, has interesting implications for future neuroprosthetics. Rather than having to interface with the grey matter right where computations are being done, we may in fact only have to interface with the white matter 'between departments' as it were, to achieve the same interface effect.
