Name: Facebook Pro: Rethinking the Interactions of Professionals
Date: November 2011 - December, 2011
The idea of FaceBook Pro originally comes from some unfortunate incidents happened in real life. For example, someone is venting about the strategy of his company but forget to keep it private; someone is complaining about the long-hour work but post it to the wrong people. FaceBook Pro aims to provide a new design of SNS interface and the interactive process to help people enjoy the facility of social networking without the risk of impairing their career. In addition to that, FaceBook Pro tries to improve the cohesiveness within the group and team-work efficiency by enabling users observe and interpret more about the colleagues they work with everyday.

Name: Expert Review: Carnegie Museum of Natural History’s DDR
Date: November, 2011
This project conducted a heuristic evaluation of the Carnegie Museum of Natural History’s Digital Discovery Room (DDR) website and proposed a summary of the evaluation including any recommendations to the museum. 
The expert review was based on Nielsen’s 10 heuristics, I evaluated two main tasks/parts of the website:

Name: Evaluating the usability of flight search websites
Date: November, 2011
This competitive analysis evaluated a list of flight searching websites on features as well as usability and usefulness. It provides helpful decision making information for new entrants. For example, consider a client who is considering adding flight searching capabilities to their popular US-based travel website. This could help them decide whether they should build their own flight search product or link to an external product.
The project is divided into three parts: 
Building feature matrix
Task walkthrough (The task is “Find the cheapest flights from Pittsburgh to Boston leaving the afternoon of November 22 and returning any time on November 26th or 27th”)

This think-aloud usability test evaluate parts of the interface of the Flickr photo website. The task places the participant in the role of a father with a daughter who is moving out of his home. The father wishes to help his daughter make decisions about what to do with the things she has left behind at his home. The father has decided to share the photographs of 11 of these belongings with his daughter using
The work involved:
Analyze the provided video clip and transcript. Create a list of both good and bad critical incidents.
For each of the critical incidents identified, a usability aspect report was written
Summarized the main insights derived from the evaluation. Specifically address the most important good critical incidents, the most severe bad critical incidents, and any recommendations with respect to the evaluated system or evaluation task.

Name: Contextual Inquiry: Gathering & Interpreting Data
Date: October, 2011
Contextual Inquiry (CI) provides researchers with a framework to collect information from and understand the user.This mini project examined how people manage their social networks. The work involved evaluating 5 CI models and deciding the two most important CI models to create. Then decided the key tasks and prepared a session protocol (set of questions and things to observe). To obtain data in a comprehensive manner, the users I observe all have at least two of these three characteristics:
10 years age difference with me
From a different culture/country
Use a social networking system/website that I do not use

Contextual Inquiry Report
Name: Designing New Tablet: User Response to Amazon Kindle Fire
Date: September, 2011
Creating the affinity diagram is a discovery process. The UX researcher has to read, think and compare hundreds of pieces of data, then finally connect these notes as dots and produce a whole picture to reveal the meaningful design pattern. 
In this project, the affinity reveals that the priceand correlated products are major issues and concerns of kindle fire. For example, it is clear that manufacturing a ‘Kindle Fire’ would cost 209 dollars whereas the actual price is only 199, but Amazon still seems to be able to gain profit because of the increase in digital contents accompanying this product. And data has proved that, due to the irresistible low price, the ‘Kindle Fire’ is indeed gaining great popularity. In terms of correlated products, generally they can be divided into two parts: the ‘Kindle Fire’ accessories and other competing products. From the diagram, it is easy to see that all kinds of new accessories have already come out and other competing products have already, to different extents, been affected.
After walking the affinity diagram, one idea for tablet computer design is to simplify the functions of the device, and target these simplified products to specific user groups. A proposed idea iFun is derived from the diagram, which is building a low price subscription-based tablet product. Taking advantage of the cloud computing technology, the subscription fee will make up for the deficit between cost and price.

Date:Nov–Dec 2011  
Use the “Symbolic regression” finds the form of the equation, and the coefficients, simultaneously. Make a generation of random trees, evaluate their fitnesses, then let the more fit have sex to produce children. Maybe the children will be more fit!

Highlights of this project:
Illustrated a large number of Object-Oriented ideas such as Inheritance and Polymorphism
Utilized data structures such as ArrayList in Java Collections and added exception handling
Designed and realized the GUI using Swing components accompanied with event handling
