2. A Brief Review: Design For Web

3. Plethora of Factors Many Variables Many Variables Mix display platforms, e.g., CRT, LCD, projector, iphone, Android, etc. Mix display platforms, e.g., CRT, LCD, projector, iphone, Android, etc. Content must be transformed by a software at the viewing time (e.g., Using a Web browser to display a Website). Content must be transformed by a software at the viewing time (e.g., Using a Web browser to display a Website). These factors cause differences in the final product and challenges in design. These factors cause differences in the final product and challenges in design.

4. Design for the Web Variables include: Variables include: User ’ s display ’ s screen resolution (e.g., 800x600);User ’ s display ’ s screen resolution (e.g., 800x600); Display device ’ s color gamut (color range);Display device ’ s color gamut (color range); Display device ’ s actual size (e.g., 15 ”, 17 ” );Display device ’ s actual size (e.g., 15 ”, 17 ” ); Available fonts (discussed in details later);Available fonts (discussed in details later); Available plug-ins (discussed later);Available plug-ins (discussed later); Internet bandwidth (how fast the user can download content, discussed later);Internet bandwidth (how fast the user can download content, discussed later); Browser version and compatibility (discussed later).Browser version and compatibility (discussed later).

6. Variable: Connection Speed This variable affects every single user on the Internet! This variable affects every single user on the Internet! No matter if you make sure you use common fonts, or don ’ t require uncommon plug-ins, this factor still affects your site. No matter if you make sure you use common fonts, or don ’ t require uncommon plug-ins, this factor still affects your site. Everyone must connect to the Internet. Everyone must connect to the Internet. Different technologies provide different bandwidths (like the lanes on a highway). Different technologies provide different bandwidths (like the lanes on a highway).

7. Bit or Byte? Filesize (how big a file is on your computer) is usually measured in units of byte (B), e.g "kilobytes," "megabytes," and "gigabytes." 1 KB (one KiloByte) = 1,024 Bytes (approximately 1 thousand Bytes) 1 MB (one MegaByte) = 1,024 KB (approximately 1 million Bytes) 1 GB (one GigaByte) = 1,024 MB (approximately 1 billion Bytes)

8. Bit or Byte? Data transfer speed on the other hand is expressed in bits (b). Exampls: 1 kbps = 1,024 bit per second 1 Mbps = 1,024 Kb per second. 1 Gbps = 1,024 Mb per second.

9. Example: Download speed Download speed in KB = 124KB/sec Download speed in Kb = 124K * 8 b/sec = 992 Kb/sec or 992 Kbps Download speed in Kb = 992Kb/sec

10. What is your internet speed? http://www.speedtest.net http://www.speedtest.net http://www.speedtest.net Website for Mobile Device (save bandwidth) http://m.facebook.comhttp://m.facebook.comhttp://m.facebook.com http://hk.m.yahoo.comhttp://hk.m.yahoo.comhttp://hk.m.yahoo.com http://www.openrice.com/mobilehttp://www.openrice.com/mobilehttp://www.openrice.com/mobile

11. What is your internet speed?

12. Speeds of mobile technologies GSM Modem 9.6 – 14kb/s but typically 9.6kb/s too slow for web browsing GPRS 56 – 114kb/s but typically about 33kb/s similar to dial-up modem speeds for PCs, suitable for web browsing EDGE 2.5G 236 Kb/s 3G 384kb/s but typically about 144kb/s less than typical ADSL broadband speeds for PCs but adequate for streaming music and video (under ideal conditions) 3.5G HSDPA 1.8Mb.s ~ 7.2 Mb/s 802.11b (WiFi) 11 Mb/s (11000kb/s) – typically 4 Mb/s connection between base station and handset/laptop 802.11g (WiFi) 56 Mb/s (56000kb/s) – typically closer to the same speeds as 802.11b 802.11n (WiFi) or 802.16 (WiMax) 70 Mb/s (70000kb/s) – over much wider distances than WiFi

13. iPad: Wifi + 3G

14. SmarTone: 3G vs Wifi

15. PCCW: 3G vs Wifi

16. Connection Speed A lot of the Internet users are still using 56K modems. A lot of the Internet users are still using 56K modems. 56K = 56 kilobits = 56, 000 bits. 56K = 56 kilobits = 56, 000 bits. Remember, Remember, 1 byte = 8 bits1 byte = 8 bits 56000bits/8 = 7000 bytes = 7 KB56000bits/8 = 7000 bytes = 7 KB At the most, it downloads at 7KB per second.At the most, it downloads at 7KB per second.

17. Connection Speed Most users will not wait any more than 10 seconds for a site to load. Most users will not wait any more than 10 seconds for a site to load. On a 56K modem, a site that is only 70KB will take over 10 seconds to load completely. On a 56K modem, a site that is only 70KB will take over 10 seconds to load completely. Unlike print, the web requires a minimalist design strategy where less is more. Unlike print, the web requires a minimalist design strategy where less is more.

Try surfing the Internet on slower modems or mobile devices such as 28.8KBps, 33.6KBps, etc. to get a good feeling of the typical modem user, mobile/3G user, wifi user.

22. Internet Browsers Similar to plug-ins, other than the different available Internet Browsers, each browser has different version numbers. Similar to plug-ins, other than the different available Internet Browsers, each browser has different version numbers. Sometimes when you look at a site using IE 8, IE7, Firefox 3.6, or Firefox 3.5, they will look different. Sometimes when you look at a site using IE 8, IE7, Firefox 3.6, or Firefox 3.5, they will look different. This means that you have to not only test out on different browsers, but also different versions of the same browser This means that you have to not only test out on different browsers, but also different versions of the same browser
