Video

Video Quality Frame – a single image Frame rate – speed of video frames per second (fps) Higher frame rate = better video display Television = 30 fps Flicker of choppiness = 15 fps Streaming over Internet = 10-30 fps

Streaming Video Data is viewed in a browser as it is being transferred to the PC and is viewed before the entire transmission has completed. Often travels over Internet at 28.8 kilobytes per second

Playing Streaming Video A video player is needed to play it on PC MediaPlayer RealOne QuickTime

To Create Streaming Video To create it: Video camera Method to convert video to digital data If camera is not digital Software to assign codec and other features Server to store the video file

Video Editing Software Saves video at different frame rates Resizes video to different resolutions Extracts clips or allows clips to be resequenced Adds narration, audio, text, and other special effects Combines video and still photographs Alters colors and changes contrast Converts file formats

Video Devices Video cameras Video capture card Video tuners Analog camcorders Digital camcorders Webcams Video capture card Convert analog to digital Video tuners Enables computers to receive television signals

FireWire Use a FireWire to transfer digital video images to and from PC May also be called IEEE 1394 cables 2 types of cables 4 pin 6 pin

Interactive Web Sites

Types of Web Sites Business sites Noncommercial sites Also known as E-commerce Noncommercial sites Educational Professional and Trade Organizations Public Interest Groups

Considerations for Design Target audience Who will visit the site? Specific designs for the Web What works well for a book or newsletter may not work for the Internet Browsers Different browsers display pages differently

Steps to Planning and Building the Web Site Define the Goals of the Web Site Define the Target Audience Know the tools you will need to plan with Storyboard Flowchart Spreadsheet

Steps to Planning and Building the Web Site (Continued) Content Decide on a theme Use appropriate language to get your message across How much space do you have for storing your Web site

Steps to Planning and Building the Web Site (Continued) Interaction What method of navigation will you use to move around the Web site? What type of hyperlinks will you use? Text Graphics Will you need plug-ins?

Steps to Planning and Building the Web Site (Continued) Visual design Consider the layout How much white space? How will you use color? Be sure that hyperlinks display Text formatting Do not underline text Consider bulleted and numbered lists Limit the amount of text on a page to prevent scrolling pages

Steps to Planning and Building the Web Site (Continued) Graphics, Videos, and Special Effects Consider: file size and download time memory requirements Monitor size and resolution Browser type

Steps to Planning and Building the Web Site (Continued) Final Guidelines Spell-check Grammar check Make sure hyperlinks work Check graphics Do they load correctly? Are they appropriate for content? Name sources for copyright Is the theme consistent throughout?

Adding Sound Files to a Power Point Presentation

Volume Control Adjustments Go to Start, Programs, Accessories, Entertainment Click On Volume Control. The following window will open: Check the Volume level on the Volume Control, CD and Mic You can adjust the volume level by sliding the volume button up and down with your mouse. Make sure the MUTE boxes DO NOT have a check mark √ in them.

Create Sound File Use Sound Recorder Record your sound file Save the file in a folder or location of your choice Edit the sound file as needed

Using Sound Recorder Go to Start, Programs, Accessories, Entertainment, Sound Recorder The button with the red dot is the record button. To begin a recording, click this button with your left mouse button.

Using Sound Recorder (Continued) When recording begins, the green volume line will change appearance. If this line does not change as the music plays, you need to go back to the VOLUME CONTROL window and check the settings. A recording will not occur unless the green volume line fluctuates. During recording the button with the red dot turns grey and the button to the left (the stop button) becomes black. Click the stop button to stop your recording.

Editing and Recording Tips Before you can edit your recording you should save it. In the SOUND RECORDER go to FILE, SAVE AS and name your recording. The file name extension on the file will be .wav Wav is the extension automatically given to any files you create with the SOUND RECORDER.

Virtual Reality

Equipment HMD – Head Mounted Display Data-Glove Force Feedback Devices

Uses for VR Simulate an environment with 3-D graphics Popular for many games Players do not have to be at the same location to participate Create 3-D Communities Users build their own world 3-D Chat

Uses for VR (continued) Science Scientists around the world can analyze data for research Military Create training environments

Medicine Doctors study 3-D models of the human body to determine effective radiation treatments for cancer Engineers in Georgia are developing a data glove that will be able to “feel” tumors in patients 130 miles away

Industry Pharmaceutical and chemical companies use virtual reality to design chemical and biological catalysts Education Students in one school district will be able to participate in experiments/labs with other school districts

Scientific Visualization Uses computer graphics to transform columns of data into images Becoming a part of the 3-D design used in virtual reality

Global Positioning Systems GPS

What is GPS? A satellite system controlled by the U.S. Department of Defense (DOD) It’s a worldwide system Designed for the military Provides specially coded signals from satellites Four satellite signals compute a position

Satellites First GPS satellite was launched in 1978. Constellation of 24 satellites was achieved in 1994. Each satellite is built to last about 10 years. Replacements are constantly being built and launched into orbit. GPS satellites weigh approximately 2,000 pounds and are about 17 feet across with the solar panels extended. Transmitter power is only 50 watts or less.

Uses of GPS GPS is used to locate objects and give directions Used as a mapping device to give/get directions

Geocaching A high-tech game of treasure hunting Uses GPS coordinates to locate “caches” (treasures) left by other individuals Use GPS coordinates to locate a cache (treasure)

Geocaching Rules Fill out the logbook Take something out of the cache (if you want to) Put something in the cache Return the cache to the exact position and condition in which it was found

Geocaching Facts Over 200 countries currently participate in geocaching GPS units can be added to handheld devices or purchased separately Units cost between $100 and $1000 Waypoints for caches are listed on the Internet
