PROTOCOL: DRIVING ENVIRONMENT SIMULATOR STARTUP



PROTOCOL: DAILY DRIVING ENVIRONMENT SIMULATOR STARTUP

Note: Use this protocol when starting up the simulator each day. This is used when the entire room has not been shut down. If the entire room has been shut down use the protocol entitled " Protocol: Complete Driving Environment Simulator Startup.”

• Turn on the APC labeled “control loader” and the white surge protector under the bottom shelf.

• Calibrate the car by first turning it’s steering wheel as far as it will turn to the left, then to the right, and then left 1 and ½ turns to stop at center.

• Flip the gray on/off switch on each projectors right side. Then, press and hold the glowing yellow button on each projector’s bottom side. When the button starts to flash release. This will turn on the projectors.

• Turn on the touch screen monitor inside the car by pressing its power switch.

• Turn on the television by pressing its power button.

• Turn on the VCR. Change the VCR channel to “Line 1.”

• Turn on laptop computer by pressing and holding button switch on the outer-left side of the computer. It will automatically boot up the text generation program. Follow directions on screen to enter data.

• Turn on the intercom speaker by flipping its power switch to the on position.

• Open the project you would like to run by clicking on the folder icon in the authoring tool. A list of projects should appear. Select the one you want by clicking on its name once and then clicking on the load button.

• Switch to run mode by clicking on the RUN tab. Once there, select your start point and click the transfer button. After the world finishes transferring, click the green run button. The simulator should now begin to run.

PROTOCOL: COMPLETE DRIVING ENVIRONMENT SIMULATOR STARTUP

Note: Use this protocol when starting up the simulator if the entire room has been shut down. If starting the simulator for daily use (parts of the simulator are turned on) use the protocol entitled "Protocol: Daily Driving Environment Simulator Startup.”

• Turn on all APC’s and the surge protector under the bottom shelf. The surge protectors are the large, heavy, black units that rest on the bottom level of the rack system. There will be three hill-shaped APCs, three box-shaped APCs, and one smaller white surge protector.

• Turn on rack computers. Turn on each switch on the back of each of the four computers in the rack system. If the upper-most computer on the rack is not running (if you cannot feel air circulating in front of the fan) open the small cover and press the bottom toggle switch.

• Calibrate the car by first turning it’s steering wheel as far as it will turn to the left, then to the right, and then left 1 and ½ turns to stop at center.

• Turn on the touch screen monitor inside the car by pressing its power switch.

• Turn on the projectors by turning on the switch on the right side of each projector. Then, press and hold the glowing yellow button on each projector’s bottom side. When the button starts to flash release. This will turn on the projectors.

• Turn on the television by pressing its power button.

• Turn on the VCR. Change the VCR channel to “Line 1”.

• Turn on laptop computer by pressing and holding button switch on the outer left side of the computer. It will automatically boot up the text generation program. Follow directions on screen to enter data.

• Turn on the intercom speaker by flipping its power switch to the on position.

• Turn on the Dell PC located at the technician’s desk. Log into windows with TTI as the login and TTI as the password. Once inside Windows, run Hyperdrive by clicking on the “circular H” icon at the toolbar.

• Open the project you would like to run by clicking on the folder icon in the authoring tool. A list of projects should appear. Select the one you want by clicking on its name once and then clicking on the load button.

• Switch to run mode by clicking on the RUN tab. Once there, select your start point and click the transfer button. After the world finishes transferring, click the green run button. The simulator should now begin to run.

PROTOCOL: DAILY DRIVING ENVIRONMENT SIMULATOR SHUTDOWN

Note: If you are simply shutting down for the day, please follow this protocol. If you must shutdown the entire room for some reason use the protocol entitled " Protocol: Complete Driving Environment Simulator Shutdown". Otherwise, the rack system should NEVER have its APCs turned off.

• Turn off intercom speaker by turning off the power switch on the side of the intercom speaker.

• Turn off the television and VCR.

• Turn off touch screen by using the power switch on the rear of the screen.

• Turn off the APC labeled “Control Loader” and the white surge protector under the bottom shelf. The displays inside the car should now be unlit.

• Turn off projectors. Turn off each of the three projectors by pressing and holding the center, green button the bottom of each projector until the button begins to flash yellow. Then release the button. When the buttons have stopped flashing turn off the power switch on the right side of the projector.

PROTOCOL: COMPLETE DRIVING ENVIRONMENT SIMULATOR SHUTDOWN

Note: If you must shutdown the entire room for some reason, please use this protocol. However, if you are simply shutting down for the day please use the protocol entitled " Protocol: Daily Driving Environment Simulator Shutdown".

• Turn off intercom speaker by turning off the power switch on the side of the intercom speaker.

• Turn off the television and VCR.

• Turn off touch screen by using the power switch on the rear of the screen.

• Turn off projectors. Turn off each of the three projectors by pressing and holding the center, green button the bottom of each projector until the button begins to flash yellow. Then release the button. When the buttons have stopped flashing turn off the power switch on the right side of the projector.

• Power down the rack system. To do this first go to the Dell PC, under the run tab in the authoring tool, right click each computer's name on the grid system. Choose the Shut Down option for each from the menu that appears. Turn off the power switches on the rear of each of the four computers in the rack system.

• Turn off the Dell PC on the desk by first shutting down the authoring tool using the close button in the upper right of its window. Then shut down Windows. Once it is safe to do say, turn off the CPU and the monitor.

• Turn off the touch screen Dell PC on the rack system by simply shutting down Windows. When it says that it is safe to do so, turn off the CPU and monitor.

• Turn off all of the APCs and the white surge protector under the bottom shelf. The displays in the car should now be unlit.

SIMULATOR SICKNESS PRE-SCREENING QUESTIONNAIRE

This study will require you to drive in a simulator. In the past, some participants have felt uneasy after participating studies using the simulator. To help identify people who might be prone to this feeling, we would like to ask the following questions.

• Do you or have you had a history of migraine headaches? ( yes ( no

If yes, please describe: _______________________________________

• Do you or have you had a history of claustrophobia? ( yes ( no

If yes, please describe: _______________________________________

• Do you or have you had a history of motion sickness? ( yes ( no

If yes, please describe: _______________________________________

• If you are a female, are you or is there a possibility that you might be pregnant? ( yes ( no

If a participant answered Yes to any of the first three questions, indicate to them they may be at a higher risk for problems resulting from simulator exposure (may trigger migraines for migraine sufferers, the confined space may be a challenge for claustrophobics, and motion sickness may be exacerbated. If a female participant indicated 'yes' to question four indicate to them they may not take part in the current study.

Additional questions which should be asked include the following questions. Depending on the answers provided they may or may not be a candidate for simulation experiments.

• Any health problems which affect driving?

• Heart problems or heart attacks?

• Lingering effects from stroke, tumor, head trauma, infection?

• Suffer from epileptic seizures?

• Shortness of breath/chronic med. Therapy for respiratory disorders/asthma?

Sex:

❑ male

❑ female

Age: ______

Are you wearing prescription glasses or contact lenses?

❑ no

❑ glasses

❑ contact lenses

What is your exposure to the driving environment simulator?

❑ first time

❑ second time

❑ more than two times

During this most recent experience in the driving environment simulator did you experience any feelings of discomfort?

|Eye Strain: |none |slight |moderate |severe |

|Temperature increase: |none |slight |moderate |severe |

|Dizziness: |none |unsteady |slight |moderate |severe |
