Effects Of Visualization On Algorithm Comprehension, Matthew Mulvey
Effects Of Visualization On Algorithm Comprehension, Matthew Mulvey
Theses and Dissertations
Computer science students are expected to learn and apply a variety of core algorithms which are an essential part of the field. Any one of these algorithms by itself is not necessarily extremely complex, but remembering the large variety of algorithms and the differences between them is challenging. To address this challenge, we present a novel algorithm visualization tool designed to enhance students understanding of Dijkstra’s algorithm by allowing them to discover the rules of the algorithm for themselves. It is hoped that a deeper understanding of the algorithm will help students correctly select, adapt and apply the appropriate algorithm …
Design And Measurement Of A Real-Time Peer-To-Peer Game, Michael D. Simonsen
Design And Measurement Of A Real-Time Peer-To-Peer Game, Michael D. Simonsen
Theses and Dissertations
Currently, multiplayer online games use the client-server architecture which is very resource intensive, expensive, and time consuming. Peer-to-peer protocols are a less resource intensive alternative to the client-server model. We implement a peer-to-peer protocol called NEO in a multiplayer game and run experiments in a lab setting and over the Internet. These experiments show us that NEO is able to run a smooth playable game, with low unused updates and low location error. This happens as long as the arrival delay is long enough to allow updates to arrive in the given time limit and the round length is short …
An Ecological Display For Robot Teleoperation, Robert W. Ricks
An Ecological Display For Robot Teleoperation, Robert W. Ricks
Theses and Dissertations
This thesis presents an interface for effectively teleoperating robots that combines an ecological display of range and video information with quickening based on dead-reckoning prediction. This display is built by viewing range and video information from a virtual camera trailing the robot. This is rendered in 3-D by using standard hardware acceleration and 3-D graphics software. Our studies demonstrate that this interface improves performance for most people, including those that do not have much previous experience with robotics. These studies involved 32 test subjects in a simulated environment and 8 in the real world. Subjects were required to drive the …
