Abstract
In this chapter, the preferences of UNITEN students in using augmented reality technology user interface applications to solve selected engineering problems are compared. Cross sectional study design and Wilcoxon-Signed Rank Test approach were adopted to analyze the difference in the rankings of the engineering applications. Within a controlled environment, this research further applies “trials within the same session but with breaks between tasks,” an affirmed reliable method in measuring learnability that has been rarely explored by any related works locally. The results were captured through descriptive statistical analysis. The findings provided reliable evidences that multiple function user interface (MFIT) is more effective than the tangible user interface (TUI) for engineering students. Simultaneously, this research also presents evidences that MFIT is better than TUI in the engineering problem solving statistically.
TopProblem Statement
Reviews on several related works has raised some problem statements that have been determined in teaching and learning in engineering field especially mechanical engineering
Key Terms in this Chapter
Wilcoxon-Signed Rank Test: Is a non-parametric statistical hypothesis test used to compare two related samples, matched samples, or repeated measurements on a single sample to assess whether their population mean ranks differ (i.e., it is a paired difference test).
Mixed Reality (MR): Sometimes referred to as hybrid reality, is the merging of real and virtual worlds to produce new environments and visualizations where physical and digital objects co-exist and interact in real time.
MFIT: Multiple function interaction technique that allows multiple task to be performed simultaneously (i.e., using two or more fingers to select options on the screen, selecting, dragging, resizing image on the screen, etc.).
Competitive Usability Testing: A kind of usability test on the design and competitors.
Global Positioning System: It is a global navigation satellite system that provides geolocation and time information to a GPS receiver anywhere on or near the Earth.
TUI: Is a user interface in which a person interacts with digital information through the physical environment.
Metaphor: Is a figure of speech that describes an object or action in a way that isn't literally true, but helps explain an idea or make a comparison.
