Chair-Mounted Computer Workstation

This project aims to develop a chair-mounted computer workstation for the US military, providing a non-traditional method of data input and extraction. The system replaces the monitor, mouse, and keyboard, allowing the user to operate the computer without being tied down. The project team has researched and produced new technologies, including a glove pointer system, visual output system, and voice commands.

  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. 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 Device Interfaces

  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. 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 Voice Recognition (cont.)
