This paper introduces the Human Information Workspace (HISpace) as a test-bed for evaluating new information exploration mechanisms. In moving from dated interaction devices and small computer monitors, we aim to utilize more natural surfaces such as tables and walls as our interaction space. In testing our theories, we have produced a number of gaming applications as test cases. Here, we repor...

With the recent emergence of a wide range of information displays that reach beyond the traditional graphics-based computer screen, it seems that the original definition of ambient display, and its focus on user attention and aesthetics, has become diluted. Instead, we propose a taxonomy of alternative information displays that is mainly based on context, in terms of the data it represents and ...

Consider the problem of visualizing high-dimensional data that has been categorized into various classes. Our goal in visualizing is to quickly absorb inter-class and intra-class relationships. Towards this end, class-preserving projections of the multidimensional data onto twodimensional planes, which can be displayed on a computer screen, are introduced. These class-preserving projections mai...

High-Order Wavefront Aberration Regularized Deconvolution (HOWARD) is a complete closed loop system developed for simulating human visual function with the primary goal of enhancing graphic computer displays for users that have refractive errors (resulting in difficulty interacting with visual displays). Visual function is a primary requirement for a human being to engage in computer usage effi...

Computer Vision is a field that studies methods for capturing numerical or symbolic information. Some of the computer vision processes are image capture, enhancement, segmentation, feature extraction, and clarification. AI-based technology allows public to carry out more optimal surveillance deal with Covid-19. During Covid-19 pandemic, many people have adopted new normal habits by implementing...

We compared matches between colours that were both presented on a computer monitor or both as pieces of paper, with matching the colour of a piece of paper with a colour presented on a computer monitor and vice versa. Performance was specifically poor when setting an image on a computer monitor to match the colour of a piece of paper. This cannot be due to any of the individual judgments becaus...

This paper introduces an interactive expression editing system that allows users to design facial expressions easily. Currently, popular example-based methods construct face models based on the examples of target face. The shortcoming of these methods is that they cannot create expressions for novel faces: target faces not previously recorded in the database. We propose a solution to overcome t...

Retrieving knowledge from a knowledge repository includes both the process of finding information of interest and the process of converting incoming information to a person’s own knowledge. This paper explores the application of 3D interfaces in supporting the retrieval of spatial knowledge by presenting the development and the evaluation of a geo-referenced knowledge repository system. As comp...

Advances in computers and software have made it possible to construct a new generation of teaching tools for automatic control. These tools have a position somewhere between ordinary laboratory processes and conventional computational tools. The idea is to have a multiple-view representation of a system and some of its attributes available on the computer screen. The objects can be manipulated ...

An experimental technique is described for eliciting a subjective evaluation of the prosody of synthetic speech by untrained listeners. The technique makes use of a graphic display time-aligned with the speech signal. Subjects are asked to indicate which parts of a recording are unsatisfactory by clicking on a computer screen with a mouse. The technique was applied to two TTS systems for French...
