Topic: Java User Interface

1. Task Summary

In this assignment, you will complete number of interrelated components.

You will formulate one or more empirical questions. You will design a data collection protocol that is relevant to the empirical question. You will implement an interactive interface that will be used as the basis for the collection of data under your protocol. You will collect the data. You will analyze the data and present your findings.

Obviously, the type of interactive interface that you implement will determine the type of data that can be collected. This, in turn, will constrain the type of data collection protocol that can be deployed. The type of data collection protocol that can be designed, in turn, will constrain the type of empirical questions that can be asked.

In collecting your data, it is permitted to deviate by using "proxy" users in place of the participants from your target population. The proxy user, in the most basic case, would be yourself. Slightly better would be to ask your friends.

2. Component: Interactive Application

You have been provided with an example codebase.

The codebase features the following:

1. An interface that features a prompt area and a single button.

2. Prompts appear to the user at regular intervals.

3. During the time that the prompt appears, the button is deactivated.

4. When the prompt disappears, the button activates.

5. If the user presses the button, the input action is recorded. An informational message is printed on the console. Message indicates the time elapsed (from the point at which the prompt appears to the time the button is pressed).

You may use this codebase as the starting point of this assignment.

2.1. Success Criteria

 A. Basic: All resources required to run the interactive app have been submitted as per submission  requirements. Javadoc has been generated.

B. Documentation:

a. Class documentation is complete, accurate, and provides sufficient detail. Adheres to javadoc requirements.

b. Method documentation is complete and accurate. Fully specifies the pre and post conditions. Adheres to javadoc requirements.

C. Correctness: application behavior matches the specification (as found in the documentation of the class that contains the main method). App compiles and runs; does not crash.

D. Design and Implementation: Interactive interface makes use of all relevant architectural and software design patterns; adheres to principles of good programming.

E. Degree of Sophistication: [only attempt if all other criteria have been satisfied] sophistication of the implementation in terms of going beyond the provided codebase. Adds substantial new functionality and/or components.

3. Component: Study Report

Prepare a document that provides the following:

• Statement of empirical question
• Description of data collection protocol
• Concise summary of findings
• Detailed analysis of data
• Appendix containing the raw data and any other intermediate formats (such as a spreadsheet)

4. Examples

The basic bones of an assignment:

Empirical Question: Of two horizontally-aligned buttons, do users press the button on their dominant side faster than they press the button on their non-dominant side? Codebase is modified to include a second button.

Quantitative data collected from a non-trivial number of participants (like, say, more than 2), with both left- and right-side dominant represented over a non-trivial number of trials. Prompts ensure equal distribution between left and right buttons, but order is randomized. Data is analyzed in a spreadsheet, and an answer provided, as supported by the mean value of time-to-press, with discussion of whether difference may be due to chance. Do not include the significance testing.

Make sure it executes all the components well with a considerable skill.
