Digital

  1. 1. Let’s Get Digital! MLCS Research Methods Terry Butler 2000 February 3
  2. 2. Let's get digital: outline <ul><li>digital resources: </li></ul><ul><ul><li>how to get them; what to do with them </li></ul></ul><ul><li>desktop publishing and web publishing </li></ul><ul><li>document conversion </li></ul><ul><li>lab practice: </li></ul><ul><li> scanning, digitizing, manipulating </li></ul>
  3. 3. What is &quot;digital&quot; <ul><li>Digital means &quot;encoded in numbers&quot; </li></ul><ul><li>A record is &quot;analog&quot;; a CD is &quot;digital&quot; </li></ul><ul><li>Digital information can be easily stored, copied, altered, transmitted and combined with other digital material </li></ul>
  4. 4. What is &quot;digital&quot; - examples
  5. 5. Digital materials - acquiring <ul><li>Analog materials can be &quot;digitized&quot; </li></ul><ul><li>They are easy to copy and adapt </li></ul><ul><li>Copyright laws protect the rights of the creator of an image -- so be careful! </li></ul>
  6. 6. Digital - Words <ul><li>Text - keyboarding or capture from printed page </li></ul><ul><li>OCR step 1: make an electronic image </li></ul><ul><li>OCR step 2: &quot;recognize&quot; letter shapes and words </li></ul><ul><li>OCR step 3: save text (with formatting) as word processing document </li></ul><ul><li>common file format: ASCII; ANSI; UNICODE </li></ul><ul><li>note: word processor formats are not standard! </li></ul>Doc
  7. 7. Digital Pictures - Photos <ul><li>photo is scanned (converted to digital form) </li></ul><ul><li>graphics software program can alter and control image as it is saved as a graphic file </li></ul><ul><li>common file formats: GIF; JPEG; TIFF </li></ul>
  8. 8. Digital Sounds <ul><li>sound is converted to digital form as it is played (or it can be &quot;live&quot; recording with a mike) </li></ul><ul><li>more difficult to manipulate than text or pictures </li></ul><ul><li>standard formats: MIDI (music); AIFF, WAV; RA (RealAudio)’ MP3 </li></ul>
  9. 9. Digital Video <ul><li>special equipment to capture - sound and pictures </li></ul><ul><li>formats: QT4 (QuickTime 4); MPG; RV (Real Video); AVI </li></ul>
  10. 10. Web Publishing <ul><li>information is encoded in HTML and &quot;published&quot; (made public) </li></ul><ul><li>before - type in HTML; now - convert document to HTML (wysiwyg) </li></ul>
  11. 11. Document Conversion <ul><li>how is text stored in a computer system? </li></ul><ul><li>operating system differences (PC vs Mac) </li></ul><ul><li>word processing file formats </li></ul><ul><li>conversions done by the operating system </li></ul><ul><li>document conversion software: </li></ul><ul><ul><li>examples: Word for Word; MacLink Plus </li></ul></ul>
  12. 12. Encoding - file formats <ul><li>standard numeric codes: &quot;c&quot; = 99 = 63 hex </li></ul><ul><li>ASCII - 128 codes; upper ASCII - 256 codes </li></ul><ul><li>ANSI - better standards for codes above 128 </li></ul><ul><li>UNICODE - all the world's characters </li></ul>HTML ANSI ASCII Doc
  13. 13. Word processing file formats <ul><li>Commercial file formats are not standard and are purposely kept changing </li></ul><ul><li>Conversion from one to another is usually less than perfect </li></ul>
  14. 14. Document conversions <ul><li>Macintosh computers can open PC files (but not vice versa ) </li></ul><ul><li>Conversion programs take the file to a &quot;common denominator&quot; then to the target format </li></ul><ul><li>Most of the conversion programs run on Macintosh: </li></ul><ul><ul><li>MacLink; Word for Word </li></ul></ul>
  15. 15. Computer Lab - Let’s get digital! <ul><li>Scanning text - using a flatbed scanner, scan in and interpret one or two pages of text (using OCR software) </li></ul><ul><li>Scanning images - using a flatbed scanner, scan in a colour picture </li></ul><ul><li>Digitizing sound - digitizing using a sound card will be demonstrated </li></ul>
  16. 16. Computer Lab - (continued) <ul><li>Document conversion - a word processing file will be converted from Macintosh to PC (or the reverse) and tested on the target system </li></ul><ul><li>Manipulating text, images, and sound files - students will work with the resulting text, image, and sound files </li></ul>
