Characterizing Navigational Tools In A Virtual Search Task, Austin Riggs
Characterizing Navigational Tools In A Virtual Search Task, Austin Riggs
All Theses
The goal of this thesis is to characterize and empirically compare navigational tools in the context of a virtual inspection task. The framework considers both directional-cue navigational tools (e.g., GPS navigation arrows) and trail navigational tools (e.g.,footprints) in comparison to a control condition. Characterizing the tools allows for documented relationships between specific navigational tool-performance combinations. It is intended that by characterizing and comparing the tools a more advantageous use of navigational tools will emerge to increase the benefit provided to both the users and implementers of virtual environments. The focus of the metrics in the paper were distance traveled, speed …
Effects Of Meeting Spaces On The Performance Of A Concept Selection Task By Engineering Design Teams, Necmettin Ozkan
Effects Of Meeting Spaces On The Performance Of A Concept Selection Task By Engineering Design Teams, Necmettin Ozkan
All Theses
Given the increasing importance of collaboration and the resulting use of virtual tools, this research investigates the performance of engineering design teams using a concept selection task in three meeting spaces, face-to-face, 2D online and 3D virtual. Cisco's WebEx and Sun Microsystems' Wonderland were used as the 2D online meeting space and the 3D virtual environment, respectively. Twenty-four two-person design teams were formed and randomly assigned to the meeting spaces. Eight teams performed a cell-phone concept selection task in each meeting space. Four dependent variables were measured: task completion time, team satisfaction, self-evaluated quality and expert-evaluated quality. Following data collection, …
