    Broadening the interface bandwidth in simulation based training

    Get PDF
    Currently most computer based simulations rely exclusively on computer generated graphics to create the simulation. When training is involved, the method almost exclusively used to display information to the learner is text displayed on the cathode ray tube. MICROEXPERT Systems is concentrating on broadening the communications bandwidth between the computer and user by employing a novel approach to video image storage combined with sound and voice output. An expert system is used to combine and control the presentation of analog video, sound, and voice output with computer based graphics and text. Researchers are currently involved in the development of several graphics based user interfaces for NASA, the U.S. Army, and the U.S. Navy. Here, the focus is on the human factors considerations, software modules, and hardware components being used to develop these interfaces

    Using teleporting, awareness and multiple views to improve teamwork in collaborative virtual environments

    Mobile Group Dynamics (MGDs) are a suite of techniques that help people work together in large-scale collaborative virtual environments (CVEs). The present paper describes the implementation and evaluation of three additional MGDs techniques (teleporting, awareness and multiple views) which, when combined, produced a 4 times increase in the amount that participants communicated in a CVE and also significantly increased the extent to which participants communicated over extended distances in the CVE. The MGDs were evaluated using an urban planning scenario using groups of either seven (teleporting + awareness) or eight (teleporting + awareness + multiple views) participants. The study has implications for CVE designers, because it provides quantitative and qualitative data about how teleporting, awareness and multiple views improve groupwork in CVEs.

    This paper describes the design of user-interface widgets that include non-speech sound. Previous research has shown that the addition of sound can improve the usability of human–computer interfaces. However, there is little research to show where the best places are to add sound to improve usability. The approach described here is to integrate sound into widgets, the basic components of the human–computer interface. An overall structure for the integration of sound is presented. There are many problems with current graphical widgets and many of these are difficult to correct by using more graphics. This paper presents many of the standard graphical widgets and describes how sound can be added. It describes in detail usability problems with the widgets and then the non-speech sounds to overcome them. The non-speech sounds used are earcons. These sonically-enhanced widgets allow designers who are not sound experts to create interfaces that effectively improve usability and have coherent and consistent sounds

    Crowdsourcing in Computer Vision

    Computer vision systems require large amounts of manually annotated data to properly learn challenging visual concepts. Crowdsourcing platforms offer an inexpensive method to capture human knowledge and understanding, for a vast number of visual perception tasks. In this survey, we describe the types of annotations computer vision researchers have collected using crowdsourcing, and how they have ensured that this data is of high quality while annotation effort is minimized. We begin by discussing data collection on both classic (e.g., object recognition) and recent (e.g., visual story-telling) vision tasks. We then summarize key design decisions for creating effective data collection interfaces and workflows, and present strategies for intelligently selecting the most important data instances to annotate. Finally, we conclude with some thoughts on the future of crowdsourcing in computer vision.Comment: A 69-page meta review of the field, Foundations and Trends in Computer Graphics and Vision, 201

    Evolution of human computer interaction

    The work is devoted to the review of the development the human-computer interaction. In the first sections the history of computing in the "pre-computer" era is briefly described and then the early history of modern computing, methods of the first computers controlling and the tasks of programmers at this stage are described. It describes the methods of interaction with the first -generation computers using the remote control elements, punched cards and punched tapes. The section, devoted to the second generation computers, describes the emergence of high-level operating systems and programming languages. At this point, there are such means of interaction with the computer as the displays and, respectively, such programming tools as interactive languages and interactive debuggers. Research is also beginning on principles of human-computer interaction the infancy of the discipline "computer graphics", the development of computer graphics packages and the emergence of interactive computer graphics standards are considered. In the section “Revolutions in computer science” describes the appearance of a large number of the same series computers and the first super-computers in the context of human-computer interaction. Revolutionary changes are considered in computer graphics and emerging of the science discipline “computer visualization” with its parts “scientific visualization”, “software visualization”, “information visualization” and also “programming by demonstration”. The information about the attempt to create a fifth generation computer based on logical programming is given. It is told about the initial period of teaching programming. The creation of computer networks and the emergence of personal computing as well as the creation the tools of modern parallel computing have become the important stages in the development of modern computing. The virtual reality becomes an important computer visualization tool. The modern state of human-computer interfaces is characterized primarily by emerging of natural interfaces which can be attributed Brain-Computer Interface (Neurocomputer interface, Brain-Computer Interfaces), interfaces based on the direct use of nerve impulses, speech recognition, recognition of lip movement, mimic recognition and eye tracking (Eye Gaze or Eye Tracking), haptic interfaces and also interfaces giving tactile feedback (allowing you to feel the touch),motion capture interfaces the entire human body or individual organs (head, entire arm, hands, fingers, legs), motion capture toolkits,in particular, interfaces based on leg movements (foot-operated computer interfaces), sign interfaces, sign languages. We briefly describe the activity approach to the design of interfaces and also some problems concerning the problem of mass interfaces. Finally, we discuss a number of problems arising from the increasing capabilities of modern computers. The work is in the nature of a popular science article and it largely reflects the subjective impressions of the author. © 2020 National Research Nuclear University. All rights reserved

    International audienceAfter their wide developments in the last 20 years, including domains as Interactive Computer Graphics, Human Computer Interfaces, Multimodal interfaces, Virtual/Augmented/Mixed Reality systems, we are at a end of a period in which all seems to be done. However, Interactive Computer Systems enter in new age and we are at a new cross point and at the beginning of a new period, that of enaction and enactive interaction

    Correcting menu usability problems with sound

    Get PDF
    Future human-computer interfaces will use more than just graphical output to display information. In this paper we suggest that sound and graphics together can be used to improve interaction. We describe an experiment to improve the usability of standard graphical menus by the addition of sound. One common difficulty is slipping off a menu item by mistake when trying to select it. One of the causes of this is insufficient feedback. We designed and experimentally evaluated a new set of menus with much more salient audio feedback to solve this problem. The results from the experiment showed a significant reduction in the subjective effort required to use the new sonically-enhanced menus along with significantly reduced error recovery times. A significantly larger number of errors were also corrected with sound

    AbstractThis paper surveys work within the Computer Algebra community (and elsewhere) directed towards improving user interfaces for scientific computation during the period 1963–1994. It is intended to be useful to two groups of people: those who wish to know what work has been done and those who would like to do work in the field. It contains an extensive bibliography to assist readers in exploring the field in more depth. Work related to improving human interaction with computer algebra systems is the main focus of the paper. However, the paper includes additional materials on some closely related issues such as structured document editing, graphics, and communication protocols
