1. Team Members: Faculty Advisors: Christian BaldusDavid Roberts Dr. Arun Somani Isi OamenShawn Yockey Dr. Zhao Zhang Chair-Mounted Computer Workstation Iowa State University Senior Design May06-09 Client: Lockheed Martin

2. Presentation Outline Project Overview Project goals History Use Cases of the Chair-Mounted Computer Sub-systems − Glove Pointer System − Visual Output System − Voice Commands Wrap-up and Q & A

3. Project Overview: What problem is being solved? A new tool in the toolkit for the US Military Space is at a premium on aircraft and ships Traditional laptops and computers are not always practical Need to develop non-traditional methods of data input and extraction.

4. Project goals: A different way of looking at computing Allow the user to use a computer without being tied down Develop new tools to allow this to happen − Replace the monitor − Replace the mouse − Replace the keyboard The end product must help the user: not give them an additional obstacle to overcome in performing their job

5. History We are the second team to attempt this project First team to attempt the project was May04-15 Inheritance − Pair of Goggles − Two RF circuits that do not work Key Difference − They had a budget − May06 team will research and produce new technologies but not the complete system

6. Use Case # 1: Ships

7. Use Case # 2: Aircraft

8. Glove System

9. Glove System (cont.) Functionality − Pointing device − I/O device − Spring-loaded potentiometer buttons − Use of Bluetooth wireless technology − Powered by batteries or power supply − Allows use of computer while away from workstation − May connect to utility belt for various reasons

10. Glove System (cont.) Keypad − Keyboard replacement − Projected Uses: Data entry Shortcut commands Navigation − Connectivity USB Serial Bluetooth

11. Glove System (cont.) Software − Projected uses: Integration of glove with rest of system Increased functionality − What may be used: Microsoft Windows XP HyperTerminal Off-the-shelf applications Individually written programs & scripts

12. Glove System (cont.) Bluewand − Movement sensitive input device − Equipped with many sensors − Projected uses: Remote Control Navigation device Mouse pointer − Connectivity: Bluetooth

13. Glove System (cont.) MG1101 MicroGyro − Fully integrated mini gyroscope − Dual-axis, miniature rate, self-contained − Uses I²C data technology − Possible uses: Pointing device Remote control Computer mouse − Connectivity USB Parallel port Bluetooth

14. Visual Output System Components of the prototype − Chair-mounted display − Head-mounted display − Device interfaces

15. Chair-mounted Display Requirements: − Accepts standard monitor input − Mounting Space is at a premium Must be stable Issues: − Expensive − Simple − Ultimately not needed for a prototype demonstration

16. Head-mounted Display Requirements: − Accepts standard monitor input − Minimize restriction of movement − Minimize restriction of view − Long operating life Drawbacks − Expense − Lack of wireless versions − Inheritance

17. Inherited Artifacts Goggles − Pros: Free Still works Relatively light weight − Cons: VGA connection Not Bluetooth capable without an intermediate device Disorienting Not rated for over 20 minutes of use

18. Device Interfaces May04-15 − Radio Frequency communication chip Frequency 2.4 GHz Range 6 feet − Built their own boards Large, bulky Did not work Requires more work to integrate parts May06-09 − Bluetooth Frequency: 2.4GHz Range: 32 feet − Parts available off the shelf Relatively compact Each part can work as its own unit, modular Almost plug-and-play

19. Voice Recognition Bluetooth headset − Pros : Ease of use 30 ft. range 8 hour battery 200 hour standby − Cons: Standby function Security Issues Voice to noise ratio

20. Voice Recognition (cont.) Software: Dragon Naturally Speaking − Pros : Packaged code Ease of use Executable commands Flexibility Training programs − Cons: Reliability Response time Software learning curve Microphone On/Off
