A Pattern Approach To Examine The Design Space Of Spatiotemporal Visualization, Chen Guo

Department of Computer Graphics Technology Degree Theses

Pattern language has been widely used in the development of visualization systems. This dissertation applies a pattern language approach to explore the design space of spatiotemporal visualization. The study provides a framework for both designers and novices to communicate, develop, evaluate, and share spatiotemporal visualization design on an abstract level. The touchstone of the work is a pattern language consisting of fifteen design patterns and four categories. In order to validate the design patterns, the researcher created two visualization systems with this framework in mind. The first system displayed the daily routine of human beings via a polygon-based visualization. The …

An Examination Of Presentation Strategies For Textual Data In Augmented Reality, Kanrawi Kitkhachonkunlaphat

Department of Computer Graphics Technology Degree Theses

Videos with embedded text have been widely used in the past and the text in the videos usually contained valuable information. However, it was difficult for people to fully understand the text in videos displayed on smartphones due to obstructions such as color conflicts between letters and the moving background. Adjustments to texts that would support the human visual system, such as changes to brightness and color contrast, increased legibility of text, and taking into account the phantom illumination (PI) illusion (the optical illusion that increases the perception of brightness in a certain area), should be able to improve peoples’ …

User Assisted Tree Reconstruction From Point Clouds, William P. Leavenworth Ii

Department of Computer Graphics Technology Degree Theses

LIDAR is a useful tool for quickly digitalizing real world objects, but it usually takes some effort to produce a recognizable object from the raw input. When the object is a tree, the challenge is to create a three‐dimensional model that represents its general shape, while avoiding the influence of undersampling and noise. In the method developed for this research, the user creates a sketch overlaying a display of the raw input data. Each node in the sketch creates an estimated slice of the tree skeleton at that point, and the slices are connected according to the connectivity of the …

Defining Industry Expectations And Misconceptions Of Art And Technology Co-Creativity, Vanessa C. Brasfield

Department of Computer Graphics Technology Degree Theses

The primary purpose of this study was to establish whether or not students and industry professionals share the same views about what students should be learning in animation education, what skills are necessary, and whether or not students graduating with a bachelor’s degree would be adequately prepared for an entry level position. To establish where misconceptions lie, surveys were issued to three groups: undergraduate students, post-graduate students, and industry professionals. These surveys were then analyzed using paired t-test for validation and question relevance, and ANOVA models to establish whether or not groups shared viewpoints. These data established significance within the …

Stereoscopic Visualization As A Tool For Learning Astronomy Concepts, Norman M. Joseph

Department of Computer Graphics Technology Degree Theses

Three-dimensional (3D) visualization is becoming an extensively used educational tool. 3D visualization tends to be most useful when demonstrating concepts involving the very large – such as astronomy, or the very small – such as nanotechnology. Stereo visualization allows students to familiarize and immerse themselves in worlds which are difficult or impossible to experience in real life. This study will evaluate the educational benefit of teaching lessons involving a highly spatially-oriented topic (astronomy) using stereoscopic visualization technology.

We have used a stereoscopic visualization system, installed in a classroom, to deploy 3D simulation packages for use in classroom instruction. This educational …

Visual Learning Styles Among Digital Natives, Eric Palmer

Department of Computer Graphics Technology Degree Theses

This study explored the concept of digital nativity and its educational implications, including application of the learning styles hypothesis. The concept of digital natives, first put forth by Marc Prensky, introduced the notion that individuals raised in a technological environment have developed in such a way as to utilize information differently than the non-native generations before them. This study examined the possibility that these differences may include an increased efficiency in the utilization of narrative imagery versus textual information. The potential benefit of utilizing narrative imagery as an instructional tool is discussed. An experimental test application was developed for the …
