Introduction
This section will provide a brief description of ViSTA, and expectations of our group. In order to
describe ViSTA, we will ask three questions to ourselves, and answer them. First of all, ViSTA
and it is main purpose will be explained. Also, main reason behind ViSTA will be provided.
Finally, details of development process will be described.
What is ViSTA?
ViSTA is short term for Visualization of Scanpath Trend Analysis. The main goal of the ViSTA
project is visualization of STA algorithm, and gaze map that STA algorithm applied; however,
project should be implemented in a modular way that enables other algorithms to be implemented
easily. Simply, it is a visualization tool for eye tracking data algorithms such as STA.
Why this project is being developed?
STA is a new algorithm that doesn’t have any visualization tool for itself. This is the main reason
why this project is being developed; however there are some other constraints that take this project
far advanced than being a just visualization tool for an algorithm, and that is modularity. There are
so many different visualization methods, scanpath analysis tools, algorithms, and more to come in
each year. Diversity is keyword for eye tracking, and in order to catch this trend, creating a
framework for STA that is ready for change is important.
How it is being achieved?
One of the constraints for this project is modularity, and to achieve that object oriented
programming is important. The other important constraint is diversity, and to overcome this issue
generalizing some cases, and creating standards is important. Also, selecting best visualization
methods is the most important thing in case of diversity. Lastly, for chosen visualization methods
finding best visualization tools, and using them is important. Simply, doing literature survey on
visualization methods is the most important step to achieve ViSTA.
Backgrounds, Aims & Organization
Formulation of Design Problem
The main concern about ViSTA is visualization of STA algorithm. However, only visualizing STA
algorithm is not enough, but visualizing of all raw data is also important
We have been given this project because of STA algorithm does not have its own visualization
tool. There is only text format input and output, and offline access that current implementation
uses.
There are several different visualization techniques for gaze paths and trending paths. One of the
other concern about ViSTA is researching and choosing best technique among them.
Shortly, ViSTA is about choosing best visualization technique for STA algorithm and
implementing it in an online and much more user-friendly environment.
