Project Description:

Fallarm is a pervasive fall prevention solution suitable for hospitals and care facilities. This project was to develop a User-Interface using JavaScript. This required the creation of a user-interface system that displays the transactions.

Responsibilities:

• The system is designed to learn from users to more precisely identify patient activities. Algorithm is designed to achieve this function.

• Use UML tools model business process and analysis, design, implementation system.

• Network part designing is for communication among device, server and client (Response Center). The customer device records activities 24/7 and send to server through socket programming, and alert information will be sent to caretaker when adverse event detected.

• Device will generate information and estimate risk class. Android emulator acts one client. Develop application for spatial coordinates generating. Normally this information will be stored in database using MySQL. When alert detected server will send information to Client (Response Center) with HTTP and secure HTTP protocol.

• Coding using Java Servlets, created web pages using JSP’s for generating pages dynamically.

• Designing, coding and configuring server side J2EE components like JSP, Servlets, Java Beans, XML.

• Deploying applications to server, Tomcat6.0.

• Spring MVC, Hibernate3 configuration

• Learned XML for communicating client.

• Rigorously followed Test Driven Development in coding.

1. Created a composite page to show data in tree structure, and display each level detail in the same page

2. Listening for the user behavior and use Ajax to asynchronously retrieve data from database(MySQL)

3. implemented server-side language by using PHP

4. Written documentation for all implementation

5. Used PHP(regular expression) to crawl data from external website and display in my own layout page

6. Developed an Android App which includes Google GPS info (respond GPS location in real-time), listing phonebook info and call corresponding contacts, making a connection with two Android phones via Bluetooth for sharing data.

7. Responsible for the front end graphical user interface design, and support, maintain, and document software functionality
