Development Of Tangible Code Blocks For The Blind And Visually Impaired, Hyun Woo Kim Jan 2023

Development Of Tangible Code Blocks For The Blind And Visually Impaired, Hyun Woo Kim

Theses and Dissertations

The fields of Science, Technology, Engineering, and Mathematics (STEM) have been growing at an accelerating rate in recent times.

The block based programming language, Scratch, was specifically designed to lower hurdles to learning how to program for sighted students. Unfortunately, although very effective and widely used in K12 classrooms, Scratch, similar to other block based languages, is inaccessible to students who are blind and visually impaired (BVI). This thesis is part of a larger project to make the …

Big Data Visualization Platform For Mixed Reality, Aliakbar Panahi Jan 2017

Big Data Visualization Platform For Mixed Reality, Aliakbar Panahi

Theses and Dissertations

The visualization of data helps to provide faster and deeper insight into the data. In this work, a system for visualizing and analyzing big data in an interactive mixed reality environment is proposed. Such a system can be used for representing different types of data such as temporal, geospatial, network graph, and high dimensional. Also, an implementation of this system for four different data types are created. The data types include network data, volumetric data, high dimensional, and spectral data for different mixed reality devices such as Microsoft HoloLens, Oculus Rift, Samsung Gear VR, and Android ARCore were created. It …

Beyond Description: Converting Web Site Usage Statistics Into Concrete Site Improvement Ideas, Julie Arendt, Cassie Wagner

VCU Libraries Faculty and Staff Publications

Web site usage statistics are a widely used tool for Web site development, but libraries are still learning how to use them successfully. This case study summarizes how Morris Library at Southern Illinois University Carbondale implemented Google Analytics on its Web site and used the reports to inform a site redesign. As the main campus library at a research university with about 20,000 undergraduate and graduate students, the library included resources from multiple library departments on a single site. In planning the redesign, Morris Library's Virtual Library Group combined usage reports with information from other sources, such as usability tests …

Location, Location, Location: A Transaction Comparison Of Catalog Searches Originating From The Library Homepage And Aleph, Jimmy Ghaphery, Thomas Mcnulty, Susan Teague Rector

VCU Libraries Faculty and Staff Presentations

Jimmy Ghaphery, Head, Library Information Systems, Virginia Commonwealth University (VCU); Thomas McNulty, Integrated Library Systems Librarian, VCU; Susan Teague-Rector, Web Applications Manager, VCU. We will analyze several weeks of search terms from February 2009 in order to determine how different points of entry impact user searches. Specifically we will compare user searches originating from a search tool on the library homepage and searches originating directly from Aleph. This session should be of interest to those who are involved with usability and OPAC design as well as system administrators tasked with measuring OPAC activity.

Faced with the challenges inherent in designing online search interfaces and the ever-growing amount of resources available online, VCU Libraries sought to explore how to build effective search interfaces that, at the same time, support a wide variety of computer users and provide comprehensive access to assorted collections of electronic resources. Over a 9 …

Vcu's My Library: Librarians Love It. . . . Users? Well, Maybe, Jimmy Ghaphery, Dan Ream Jan 2000

Vcu's My Library: Librarians Love It. . . . Users? Well, Maybe, Jimmy Ghaphery, Dan Ream

VCU Libraries Faculty and Staff Publications

Virginia Commonwealth University's My Library project (circa 1998-1999) has chosen "ease of use" as its primary design criteria. The development of this tool using Perl scripting is described, and reports derived from usage logs are analyzed here. My Library tends to appeal a great deal to a small number of users as a personal tool. Librarians have found it popular as a class teaching tool, with pages designed for specific classes in library instruction receiving the heaviest use.
